A Robust Integrated Watermarking Algorithm for Vector Geographic Data Copyright Protection

Vector geographic data play an important role in the natural resources and environment sector as well as in other location information services. This is also one of the types of data where the cost to create it is relatively large because of the difficulty in surveying, collecting, and authorizing. The rapid development of the Internet has created many advantages in the distribution, exploitation, and use of vector geographic data, but it also gives rise to many problems such as duplication, redistribution, forgery, and illegal data use. The theft on the Internet is becoming more and more sophisticated and the number of violations is increasing, showing the urgent need to research and develop an effective solution to protect the copyright of vector geographic data and prevent them from being illegally collected and used. Among the major studies and solutions, digital watermarking emerges as an effective method and is an active research area for copyright protection. Towards a good solution for copyright protection of vector geographic data, our study proposes a new algorithm with three main contributions, including: (1) generating short, pseudo-random meaningful watermarks to in-crease robustness and to enable automated as well as visual manual verifying; (2) building a uniformly distributed mapping between the vertex coordinates and the watermark bit indexes to increase the robustness of the watermarks; and (3) integrating two types of watermarks, namely, spatial domain-based watermarking and zero-watermarking to be resistant to most common attacks on geographic vector data. The algorithm works on all types of vector geographic data, including points, polylines, and polygons.

Resilient Localization and Coverage in the Internet of Things

The proliferation of the Internet of Things (IoT) has revolutionized traditional services, giving rise to emerging smart infrastructures by connecting the physical and digital worlds. Sensory data is essential in IoT-based systems for providing context-aware and location-based services. Hence, the accurate localization of IoT devices is paramount. Anchor misplacement can significantly affect location information and coverage services in IoT. We study the effect of anchor misplacement in typical IoT settings where sensors are randomly deployed, can be mobile, and may belong to multiple providers. We identify sensing coverage holes formed by anchor misplacement and analyze their presence and impact. To mitigate the impact of anchor misplacement on network reliability, we propose a framework to identify the affected sensor nodes and then identify and remove misplaced anchor nodes. The validity of our approach is verified, and its effectiveness is demonstrated by several experiments with different network topologies and parameters. Our results are promising and can be utilized in multiple coverage applications, such as smart agriculture systems and habitat monitoring, regardless of the sensors or deployment types. It also sheds light on best practices and methods for a reliable design of IoT-based systems.

Indoor Positioning Technology and Control of Mobile Home Service Robot

With the rapid development of the market economy, location information services have shifted from outdoor to indoor, requiring higher system accuracy. Indoor positioning and control is an indispensable technical support for mobile home service robots to perform system tasks, and this technology is also an important parameter that marks the level of intelligence of a home service robot. However, in indoor places, how to obtain the target node location information timely and accurately and how to control and path planning should be the first issues to be considered in the design of home robots at this stage. This article gave a brief overview of the current indoor positioning technology and control, analyzed the more widely and frequently used indoor positioning methods, and deeply studied the ultrasonic positioning technology. On this basis, a mobile home service robot system was designed, and simulation experiments were carried out, respectively, to test the receiving time and arrival time of the node signal, the node positioning accuracy, the optimal degree of route planning, and the absolute and relative errors of navigation and path estimation. The experimental results showed that the accuracy of the robot system positioning proposed in this article reached more than 80%, and the relative error was only 4.21%, which verified its feasibility and effectiveness in practical applications. Popularizing it in the market can effectively improve the system performance and intelligence of home service robots.

INDOOR POSITIONING METHOD BASED ON SINGLE BASE STATION AUDIO SIGNAL

Abstract. The growth of the Internet of Things has increased demand for location information services, but existing indoor positioning technology has limitations. The purpose of this paper is to discuss indoor positioning with a single audio base station and to propose an indoor positioning method based on signal strength. The proposed method is simple to use on smart phones, and the base station is straightforward to deploy. The base station transmits digital amplitude modulated signals in multiple directions using this method. Prior to the test, a database is created with the signal strengths measured at multiple points throughout the area to be evaluated. During the test, the terminal measures the signal strength and compares it to the database to determine the spatial position. Indoor dynamic and static tests are conducted to evaluate the method’s performance. The test results demonstrate that the positioning method is highly accurate and will meet the requirements for indoor location-based services.

Precise Indoor Path Planning Based on Hybrid Model of GeoSOT and BIM

With the improvement of urban infrastructure and the increase in the coverage of high-rise buildings, the demand for location information services inside buildings is becoming more and more urgent. Moreover, indoor path planning, as a prerequisite and basis for realizing path guidance inside buildings, has become a research focus in the field of location services. This makes the accurate planning of indoor paths an urgent problem to be solved at present. This requires dynamic and precise planning from static fuzzy planning, and the corresponding scene converted from a two-dimensional plane to a three-dimensional one. However, most of the existing indoor path planning methods focus on the use of two-dimensional floor plans in buildings to build indoor maps and rely on traditional path search algorithms for pathfinding, which lack in the efficient use of the building’s own geometric and attribute information and lack consideration of the internal spatial topology of the building, making it difficult to meet the needs of indoor multi-layer continuous space path planning. Considering this relationship, it is difficult to meet the path planning needs of indoor multi-layer continuous spaces. In addition, the two-dimensional expression dominated by arrows and line drawings also greatly reduces the intuitiveness and interactivity of path expression. Regarding this, this paper combines the GeoSOT grid with accurate real geographic information and the BIM model and proposes an accurate indoor path planning method. Finally, using Guanlan Commercial Street in Baiyin City as the experimental object, the precise planning and generation of indoor paths and the interaction of visual displays on the web page are realized. It has been verified that the method has certain reference and application values for meeting the demand of location information services in buildings and building an integrated indoor–outdoor navigation service platform.

Implementasi Aplikasi Sistem Informasi Pemerintahan Daerah (SIPD) pada Dinas Perpustakaan dan Kearsipan Kabupaten Aceh Barat

The Regional Government Information System was built to facilitate the delivery of local government information to the public and was developed to produce interconnected and integrated electronic-based local government information services. This study aimed to determine the extent of the application of the Regional Government Information System application at the Library and Archives Service of West Aceh Regency. This study used qualitative methods. The data were collected with the data observation and interview, and were analyzed by using data reduction, data presentation, and drawing conclusions. The results of the study illustrated that the implementation of the Regional Development Information system application at the Library and Archives Service of West Aceh Regency was not optimal. This could be indicated that the behavior of Human Resources (HR) was not ready to face the application of the regional Government Information System application in every field due to the lack of socialization and training at the Regional Apparatus Work Unit level. Therefore, the entering regional development planning data could not be finished at the time given by Bappeda in West Aceh. The implication of this research was that the local government is obliged to provide information on regional development and regional financial information which is managed in the Regional Government Information System directly integrated with the Central Government in providing the information to the public regarding the administration of local government.

Resilience and coastal governance: knowledge and navigation between stability and transformation

Several intergovernmental agreements highlight the need for resilience in the face of environmental and societal challenges. Coastal systems are particularly complex and susceptible to global climate change, and building human resilience to future changes is of high priority. While the concept of resilience has historically been associated with stability to perturbations, the notion of transformation within the social-ecological resilience (SER) approach has recently gained importance in ecosystem management. In order to operationalize resilience in the context of coastal governance in a changing climate, a better understanding of the concept is required. This paper provides an overview of different approaches to resilience, including stability and transformation, in order to understand resilience as a concept in a coastal governance context. Subsequently, we propose five steps and three types of knowledge (system, target, transformative) with which to embed SER in coastal governance. In addition, we consider scale and system boundaries; identify (un)desirable system characteristics and the role of normative goals and common visions in resilience management. Finally, we highlight the central role that local actors and information services play in fostering a two-way exchange between science and society and tailoring solutions for establishing or enhancing SER to the needs of local actors. We conclude that the navigation between stability and transformation within the concept of resilience is central to finding sustainable future pathways in the face of climate change.

Action Planning Checklist for Social Determinants of Health: Older Adults with Chronic Conditions

In order to provide prognostic information for gerontologists who regularly counsel families, we determined to measure the longevity of subacute patients who have feeding tubes and tracheostomies. This study compares two cohorts of patients: 2002-2006 and 2015-2019. T-tests were performed to compare the total days in acute care, the total survival days, and the number of hospital admissions between the two groups. Results revealed (2002-2006, 2015-2019), some variance in the acute care days between the two groups (M= 15.4186, 21.49438) and p= .66. There is a wide difference in the total survival days between the two groups with individuals from 2015-2019 living longer than 2002-2006 (M= 229.8198, 644.0449), p< .001. However, there is no statistically significant difference in the number of hospital admissions between the two groups (M= 0.994186, 0.7752809), p= .09754. We hypothesize that advances in technology, medicine, and care over the span of 17 years contribute to increased longevity. On average, patients in the 2015-2019 group survived 414 days longer than the first group. Yet, even with such advances, more days were spent in acute care in the second group (2015-2019). Our data show subacute longevity has nearly tripled in the last decade. Although patients are living longer, they are often in a vegetative state; in most instances, there is no apparent improvement in quality of life. This study provides current data which will help gerontologists improve prognostication and allow them to form a more realistic long view of care.

KELOMPOK INFORMASI MASYARAKAT DAN MASYARAKAT INFORMASI (Studi Kasus Kontribusi Kelompok Informasi Masyarakat Dalam Mewujudkan Masyarakat Informasi di Kota Magelang)

This paper aims to describe the contribution of Community Information Group in the development of the information society. The development of an information technology based service city, needs to be supported by community readiness. They are entities who have high information needs, able to apply information technology in various fields, and able to exchange digital data quickly over long distances. Currently, the Magelang City Government is committed to implementing a Smart City, supported by Magelang Cerdas Application, that makes it easier for the public to access local information and public services. However, community response is still low, so community information groups need support in encouraging the success of local government programs. The problem is studied descriptively qualitatively, by taking the location in Magelang City. Informants are officials of the Communication Informatics dan Statictics Agency and also management of Community Information Group who were chosen purposively. Research findings state that Community Information Group contributes in disseminating government programs to the community. However, the efforts made were less than optimal due to coordination factors, lack of human resources commpetence, priority issue, and budget issue.

The LADM Valuation Information Model and its application to the Turkey case

Spatial data in a Land Administration (LA) establish a fundamental geospatial data theme (see UN GGIM, 2018) and the integrated geospatial information framework for any Spatial Data Infrastructure (SDI). Domain-specific standards, an integral component of the SDI, play an essential role to represent the semantics of domains, specify links between distributed registries and databases, and stimulate the development and implementation for Land Administration Systems (LAS). As an international descriptive standard providing an abstract conceptual schema, the ISO 19152:2012 Land Administration Domain Model (LADM) has been used and is being used as a reference for the implementation of LAS. Various approaches have been used for the LADM implementation that includes elaborating (via a country profile) and realizing a technical model suitable for the implementation (van Oosterom and Lemmen, 2015).LADM focuses on a specific function of LA that is interested in Rights, Responsibilities and Restrictions (RRR) affecting land, and the geometrical components thereof. The land value function of LA is considered outside the scope in the first edition. Recently, for extending the flexible and modular basis of the LADM, a valuation information model is developed for the specification of valuation information maintained by public authorities. It identifies the links between property valuation and the other LA registries and databases (e.g., cadastre, land registry, building and dwelling registries) that may enable interoperability across systems. The conceptual schema of the model provides a common basis to direct the development of local and national valuation databases and information technology products and services, following an approach similar to the LADM implementation. The proposed LADM Valuation Information Model is on the agenda of the development of the second edition of LADM within ISO/TC211.The operability of the newly proposed conceptual model needs to be evaluated through technical implementation. This paper describes the development of a prototype for the implementation of the LADM Valuation Information Model and assesses its operability through a case study for Turkey. The primary aim of the paper is to test the capabilities of the LADM Valuation Information Model using the required and produced data in recurrent valuation processes, but not to build a specific information management system for Turkey. As the implementation of a LADM compliant prototype initially requires the development of a country profile at conceptual level, methodologies applied for LADM profile development are examined and then a Turkish LADM Valuation Information Model country profile is proposed using the Conceptual Schema Languages (CSL) of the Unified Modelling Language (UML) and INTERLIS. INTERLIS is a formal language as well as a set of software tools that support LADM implementations. Subsequently, approaches and tools used in the LADM implementation are investigated and utilized for the automated transformations from the country profile to several technical models. In this context, the article presents the experiences gained during the implementations. Moreover, strategies for implementing and managing property valuation information more efficiently (e.g. bi-temporal aspects of valuation information management) are also studied and applied to the implementation. The generated technical models are then populated with sample datasets related to recurrent property valuation including the geometries of valuation units, as well as valuation information covering several years. The developed prototype is then tested through a number of queries to assess whether the LADM Valuation Information Model fulfils information management needs of recurrent valuations. The main contribution of this paper is to provide a holistic approach on how to develop an LADM conformant prototype for managing property valuation information.

Community Public Safety Evaluation System Based on Location Information Service Architecture

The establishment of communities is for the better operation and management of cities, and community safety has gradually become a topic of increasing concern. It is not only an important part of the community public safety system, but also the foundation of social and economic development. With the improvement of the overall economic level of society, wireless network coverage has been greatly improved, smart devices have also been rapidly developed and popularized, and location-based information service systems have gradually entered the field of community public safety. At present, my country still lacks experience in community safety management. At the same time, there is no complete set of standards and evaluation system for the public safety evaluation system of urban communities. However, community public safety involves people’s livelihood issues and the stability and development of the city. Therefore, it is urgent to build a community public safety evaluation system based on the location information service architecture. Based on the safety community research and location service system, this paper uses the combination of theory and practice, quantitative and qualitative methods, and tentatively explored and constructed a community public safety evaluation system based on the location information service architecture. This article integrates location information service technology into the community public safety evaluation system, selects three indicator factors, investigates a more comprehensive evaluation subject, and combines the evaluation subject’s qualitative evaluation of community public safety with quantitative evaluation through fuzzy comprehensive evaluation. This paper conducts an empirical analysis of a certain community and finds that its public safety evaluation score is 62.6232 points, which is in the “general” ranks, and it needs to be combined with the location information service system to improve the community safety issues. This study has guiding significance for ensuring community public safety and has theoretical and practical significance for community construction and development.

Systematically Quantifying IoT Privacy Leakage in Mobile Networks

Privacy leakage of Internet of Things (IoT) has become a great challenge with the popularity of IoT services through mobile networks, such as smart homes, wearables, and healthcare. While previous work summarized general structures to analyze IoT privacy and provide case studies of specific devices or scenarios, it is still challenging to conduct a comprehensive and systematic quantification study of large-scale IoT privacy leakage in real world. To combine systematic analyses with real-world measurements, we provide a method to quantify IoT privacy leakage on a large-scale mobile network traffic data set containing 47651 IoT devices. We generate privacy fingerprints and attribute them to a privacy quantification framework. The framework is constructed based on the semantics of multiple privacy sensitive markers selected from the traffic along with the involved network entity types in IoT (i.e., user, device, and platform), and the fingerprints are generated from sensitive information extracted in the traffic via their markers. Our quantification shows that IoT users, devices, and platforms have considerable risks, respectively. Moreover, IoT devices have a larger scale of privacy leakage than users and platforms, and they perform different daily patterns on privacy leakage following their working conditions. In addition, we present three case studies on the leakage of location information, application calling, and voice service, which illustrate that a third party can profile a network entity in both cyberspace and physical space.

Photo Based Location Information Services Using Encryption Free Framework with Duplicate Checking

In mobile, many applications provide services to the users based on the photos provided by the user.Certain applications, client users take a photo of a certain spot and send it to a server, the server identifies the spot with an image recognizer and returns its related information to the users.It can cause a privacy issue because image recognition results are sometimes privacy sensitive.To overcome the problems of existing approaches, proposed an Encryption-Free framework for Privacy preserving Image Recognition, called Enfpire.InEnfPire, the server cannot identify the client users current location, its candidates can only be presented. In proposed thefeature extraction with CNN algorithm help to collect the unique and accurate features from input image and also used Duplicate Detection process to detect images with same features present within same index.In proposed approach user transform the extracted image feature x into y on the user server and sends it to the public server.With the transformation , the effectiveness of the original feature x is degraded so that the public server cannot uniquely recognize the spot-ID of user from y.It only retrives the relevant spot ID’s.The unique spot ID will identify and information regarding the spot and relevant images will be given to the user.

IoT device location information storage system based on blockchain

In recent years, with the development of technologies such as the Internet, sensors and RFID, the application of the Internet of Things in various industries has deepened, resulting in a large number of new technologies, new products and new applications. There are a large number of devices in the Internet of Things. The interconnection of location information of these devices brings convenience to people’s lives, and there is also the problem of leaking location privacy. Therefore, effective management of the location information of the device is crucial to the development of the Internet of Things. At present, in the aspect of device location information supervision, the traditional encryption method or the location information is generally blurred, which improves the security of the location information, but also reduces the applicability of the location information. Aiming at these problems, based on the research on the equipment positioning of the Internet of Things and the key technologies of the blockchain, this paper designs a location chain storage system for IoT devices based on blockchain, and experiments the system. The results show that the number of transactions in the block has a significant impact on the time the system provides location services. The number of transactions in the block can be reasonably set by calculating the network nodes in the blockchain. The results show that the system can protect the device. Providing location information services to users under the premise of location privacy.

Digital local information services in developing countries: Evidence from Colombia

This exploratory research identifies and investigates factors that affect the delivery of local information in a developing country. The service provider and 195 local institutions based in Medellin, Colombia collaborate through an online portal, Infolocal, constituting a local information landscape (LIL). The study implements a conceptual framework for the LIL and highlights deficiencies in traditional local information service models. A Delphi study was conducted with global experts of local information services (LIS) in order to refine the traditional Unified Theory of Acceptance and Use of Technology model constructs for the Infolocal information service. Second, a survey was developed based on the revised categories (effort expectancy, performance expectancy, social influence, facilitating conditions, organisational support, and affective commitment) and disseminated to the local institutions to assess their perceptions of the service. This data was then evaluated using exploratory factor analysis. The study found that theories of technology acceptance were insufficient in explaining the disjunctions in the information landscape of this service. This study contributes to closing a gap in understanding the perceptions of LIS practice from the perspective of institutions that engage directly with citizens’ technology acceptance and use behaviour in a multilevel relationship. This article captures, compares, and analyses the disjunctions between the theoretical frameworks as espoused by experts and the practices of LIS.

Design and Implement of Pets Management System using Mobile Phone

Products for companion animal management system using smart phone are rapidly expanding as the pet animal industry grows globally. In this paper, we tried to broaden the application by integrating various contents about companion animals. We aim to apply various contents related to companion animals such as information management, schedule, health care, QR code, SNS, shopping, and location information service to the application. As a result of this research, we found that the new synergy effect was achieved through the integration between the contents, and the application field of the contents was widened due to the increased connectivity. In this study, we have developed a synergy effect through the integration of various contents by adding various contents related to companion animals and studied the necessary parts to expand the application field by increasing the interaction and connection between functions. Improvements and differentiations include comprehensive content management and comprehensive information management and sharing through QR CODE SYSTEM. As a result of the production and execution of this PET-IN, the interactions between the respective contents smoothly complemented the disadvantages and the advantage was maximized. In addition, by creating synergy effect of new effects, various functions can be applied more than other applications, and it is wider and more efficient in function. The user's feedback is reflected, and more content is added to further expand the function and efficient linkage can lead to the user's use of the application and the high effect of the function linkage can lead to the satisfaction of the user. This implies that comprehensive content composition is required for companion applications and may be important data for composing contents of companion animal applications in the future.
