Face masks are an essential tool to mitigate the ongoing SARS-CoV-2 pandemic: a call to action

Over the past several months, an increasing volume of infor- mation has expanded awareness regarding the transmission of SARS-CoV-2, the novel coronavirus associated with COVID-19. Following the pandemic declaration by the World Health Orga- nization (WHO), global authorities immediately took measures to reduce the transmission and subsequent morbidity associa- ted with this highly contagious disease. However, despite initial success in “flattening the curve” of viral transmission, many areas of the world are currently experiencing an increase in com- munity transmission, threatening to replicate the early public health emergencies experienced by Italy (1,2). In addition, the possibility of contact tracing through geosocial applications and public service platforms have been met with variable interest (3). Given current spread and the upcoming influenza season, it is essential that we use our voices as experts in upper airway health and disease to educate and encourage all communities to adopt appropriate protective measures, including the routine use of facemasks.

Uncertainty in geosocial data

In data management, uncertainty and lack of information are commonly considered as hurdles to overcome. But when it comes to management of geosocial data, where data can be used to associate people with geographic locations they visited, uncertainty is frequently not just an obstacle but also a desired feature. Uncertainty and lack of information---such as knowing only approximate locations of users or knowing only some of the locations users visited---may reduce the accuracy of data analysis. They, however, may be desired, or even required, for keeping user privacy, and for using data that otherwise would not have been collected and used. Due to the heterogeneity of geosocial data, uncertainty is prevalent in geosocial applications, and should not be overlooked. In this paper, we discuss some of the causes of uncertainty in geosocial data management. We elaborate on some of the advantages and disadvantages of using inaccurate or incomplete geosocial data, and we illustrate some of the methods to cope with uncertainty in geosocial applications.

The problem of technological integration and geosocial cruising in Seoul

In this article, I challenge a focus in digital anthropology on the integration of media into everyday life. Korean queer men’s experience on geosocial applications suggests that integration is not a neutral methodology but is rather a locally negotiated concern, a management of the connection between spaces. I use the example of the sauna to illustrate that the urban structure of Seoul is frequently orientated around semi-public rooms or bang that are imagined as insulated from the rest of society. The rise of geosocial cruising applications, with their tendency to connect and unite arenas that should be kept apart, have resulted in anxiety over the exposure of men to an uncontrollable totality of social relations.

GEO HASH BASED LOCATION PROTECTION

Cell phones and the Internet have changed the correspondence and with it the lifestyle of people. This project aims to shield area security in Geo-Social Applications alongside a component of following along surveyed information. The point of this paper is to grasp territory based organizations (LBS) and recognize its key parts behind organization giving then shed some light on the limitation keeping the development movement. This project aims at providing a system for safeguarding location privacy in GeoSocial Applications along with a feature of tagging along polled data.

Survey on Preserving Location Privacy inGeosocial Applications

By tremendous improvement of pinpoint localization, more number of geo-social applications are used by millions, which gives an opportunity to interact, also sharing locations to unknown. However today’s geo-social application have many privacy issues, which can easily misused by an expert even a well known person. LocX is a latest technique used for providing security in geosocial application. In LocX working scenario, Location coordinates are transformed before updating to server. User must exchange their secret key prior to location sharing , . Medium of sharing key is via mail or messages. This mechanism is not suited for high end geosocial applications. One user can hold the secret key of his N friends. LocX is efficient but not a novel method, for reduce the complexity a new technique for Location privacy is introduced ,using attribute based encryption instead of sharing secret keys. By adopting this way, it provides performance overhead and ease of use.

Now a days there are many geo social applications which are based on large extent, so people are more concern about the security of location and respective data stored at that location. But the location privacy provided is not enough. In this paper, we are using LocX, which is a new approach for improving location privacy without adding ambiguity or relying on strong assumptions. User stores encrypted data on the server by using transformations. When user allows recommender then they can access the users location and data. LocX provides more privacy for today’s mobile devices.

Geo social networks are the new trend in the social networking now a day. With the advance in thesmart phone and internet technology they are achieving more popularity than before. These geo social networking sites make use of the location information of the users. So location privacy of the users is a very big concern. Withoutadequate privacy protection, however, these systems can be easily misused, e.g., to track users or target them for home invasion. So an added privacy must be provided in order to preserve the location of the users. In this paper we comparethe different location privacy settings that can be introduced in geo social applications and different methods that are now adopted to provide security to the users.

Advanced Security in Geo Social Applications

In real world geo social applications become more useful. But there is lot of misuse by the personal information. There are many number of security issues in the geo social applications. LocX is new technique which is used to provide the security in geosocial applications. In this process, searching of location axis points are sent to update the server. In this LocX, user will share the secret key prior to location sharing, this will provide through mail or messages. This is not compatible with high range geosocial applications. Here one user will have the secret key of his K friends. LocX is the better technique but it is not suitable for high end geo social applications. In this paper, attribute based encryption instead of sharing secret key. Using this performance overhead and easy to use.

Preserving Location Privacy in Geosocial Applications

Using geosocial applications, such as FourSquare, millions of people interact with their surroundings through their friends and their recommendations. Without adequate privacy protection, however, these systems can be easily misused, for example, to track users or target them for home invasion. In this paper, we introduce LocX, a novel alternative that provides significantly improved location privacy without adding uncertainty into query results or relying on strong assumptions about server security. Our key insight is to apply secure user-specific, distance-preserving coordinate transformations to all location data shared with the server. The friends of a user share this user's secrets so they can apply the same transformation. This allows all location queries to be evaluated correctly by the server, but our privacy mechanisms guarantee that servers are unable to see or infer the actual location data from the transformed data or from the data access. We show that LocX provides privacy even against a powerful adversary model, and we use prototype measurements to show that it provides privacy with very little performance overhead, making it suitable for today's mobile devices.

Privacy‐preserving framework for geosocial applications

ABSTRACTThe paper deals with user privacy in geosocial applications. Geosocial applications have become very popular but can misuse user's private data and location. We propose a novel solution that prevents tracking and protects against personal identity and location being misused by external attackers or service providers. The proposed framework provides security and privacy protection for geosocial applications that provide, for example, information sharing, geotagging, and monitoring of people without revealing their identity to unauthorized persons, including the service provider. Unlike current security solutions in geosocial services, our novel framework uses advanced cryptography to secure user privacy. This protection is provided by advanced group signatures ensuring data integrity, authenticity, non‐repudiation, and strong privacy protection. The paper outputs a detailed cryptographic scheme for the protection of privacy in geosocial services and its security analysis. The proposed scheme has also been implemented, and the performance results are outlined in the paper. Copyright © 2013 John Wiley & Sons, Ltd.

A Web Service for Managing Spatial Context Dedicated to Serious Games on and for Smartphones

The GeoEduc3D project aims to provide educational games for smartphones based on Geomatics and use augmented reality techniques in order to make these games more immersive. To improve the immersive and interactive aspects of those games, we focused on the exploitation of spatial context in this particular application framework (serious games, augmented reality, smart phones, and multi-users environment). Our work has thus led to the design of a solution dedicated to the management of spatial context in a multi-players environment on and for smartphones. Several contributions have been made: modeling spatial context, proposing a service-oriented architecture to manage this context, defining a Web Service Spatial Context (WSCS) and implementation of a WSCS prototype and a mobile client according to an environment exploiting FourSquare, a geo-social application.

The emergent urban imaginaries of geosocial media

A class of geosocial software applications has begun to emerge that integrates location and social networking. These applications enable public participation in the production of datasets that reveal patterns of individual perception, interaction, and experience in space. Geosocial data consist of point locations that have been created and tagged by participants with short statements about their perceptions and/or experiences. Increasingly, these data are streamed via map interface by ‘meta-geosocial’ aggregation services and are freely available to the public. In this article I suggest that as geosocial applications become more popular, the composite sketches of place that result from them will constitute increasingly accurate representations of the local collective socio-spatial imaginary. Using data collected from one of the more popular geosocial media services, I explore the proposition that collective digital imaginaries have the potential to emerge from geosocial data. And drawing on the literature of the imaginary, I argue that geosocial-based imaginaries do not simply reflect socio-spatial practice, but also inform and influence the ways that we perceive, experience and interact in space.
