Simulation of the Lightweight Blockchain Technique Based on Privacy and Security for Healthcare Data for the Cloud System

Information about healthcare is derived from healthcare data. Healthcare data sharing helps make healthcare systems more efficient as well as improving healthcare quality. Patients should own and control healthcare information, one of their most valuable assets, instead of letting data be spread out among health care providers differ. This protects data from being shared between healthcare systems and privacy. Public ledger accompanied by a decentralized network of peer's compromises patient has been demonstrated to be able to achieve trusted, auditable computing by blockchain. The use of access control and cryptographic primitives are insufficient in addressing modern cyber threats all privacy and security concerns associated with a cloud-based environment. In this paper, the authors proposed a lightweight blockchain technique based on privacy and security for healthcare data for the cloud system. The cost-effectiveness of our system's smart contracts is evaluated, as well as the procedures used for data processing in order to encrypt and pseudonymize patient data.

Systems Engineering Integration and Test Challenges due to Security Measures in a Cloud‐Based System

AbstractCloud based systems have become popular with company's Chief Information Officers and Chief Technical Officers due to their ability to support a wide range of Web based applications and services including; scalability to allow users to increase/decrease their cloud footprint real time based on demand, load balancing to optimize computing performance, and failover which allows processing/memory assets to be reassigned real time when a failure is detected or predicted on the current processing assets. In addition, organizations can lower their Information Technology (IT) costs by deferring their infrastructure maintenance/costs to the Cloud Service Provider (CSP). However, Cloud‐based security threats and mitigations are well documented in literature, and address multiple client side, network, and cloud side (service/application and data) vulnerabilities. Defined mitigations include the use of access control, encryption, key management, digital signatures, and intrusion detection/prevention systems to yield a secure cloud‐based system. Implementing these security measures adds significant system functionality to the already complex cloud‐based system that must be assessed by the system architect. The additional requirements and development must be managed by the systems engineering team, and the increased integration and test must be addressed by the systems engineering integration and test lead. This paper will highlight the scope growth realized when a system interfaces into the cloud, relative to equivalent non‐cloud based systems. The added scope will be shown to include the development, integration and test of security related hardware and software configuration items, development of significant integrated test equipment/test vectors to verify the security functionality over a wide range of conditions, multiple cooperative systems/software led activities to analyze and test software throughout its development, and the system accreditation efforts to get authorization to tie into the cloud. With this information, the systems engineering leads will have a better understanding of the challenges involved with integrating and testing a cloud‐based system and can then properly plan and budget for this activity. This paper will focus specifically on a public cloud based implementation. Hybrid and private cloud implementations will not be addressed herein.

Exploring presentation attack vulnerability and usability of face recognition systems

Commercial face recognition software intended for the use of access control is evaluated. Most of the systems are to be used with hand-held devices (smartphones). The systems under test also contain three stationary systems designed to unlock doors or other secure entrance systems. While specifics of the systems cannot be gone in-depth under test (due to NDAs), the results of the evaluation of liveness detection (or presentation attack detection) with different complexity levels and template comparison performance are presented. The robustness against presentation attack is compares with the systems usability, and highlight where current commercial of the shelf systems (COTS) stand in that regard. The results focusing on the tradeoff between acceptance, linked with usability, and security are examined, which usually negatively impacts usability. A first extension of the attacks to systems using the NIR spectrum for imaging is also presented. This is mostly limited to stationary systems as they can include dedicated hardware with NIR capabilities. This is their main differentiation to most COTS systems running on smartphones, which do not rely on dedicated hardware. Though exceptions to this already exist for example in Apple devices. It is shown that most of the systems are not secure and not user friendly, having huge problems with difficult lighting conditions while only providing the most basic liveness or presentation attack detection capabilities.

Bedrooms and beyond: Youth, identity and privacy on social network sites

This article considers young people’s identities and privacy on social network sites through reflection on the analogy of the teenage bedroom as a means to understand such spaces. The notion therein of intimate personal space may jar with the scope and complexity of social media and, particularly, with recent emphasis on the challenges to privacy posed by such environments. I suggest, however, that, through increased use of access controls and a range of informal strategies, young people’s everyday digital communication may not be as out of control as is sometimes inferred. Recent adaptations of the bedroom analogy indicate that social network sites retain intimacy and that their individual-centred format continues to facilitate the exhibition and mapping of identities. Although an awkward fit, I suggest the bedroom may still help us think through how social network sites can function as vital personal home territories in the midst of multi-spatial patterns of sociability.

Monitoring System for Prisoner with GPS using Wireless Sensor Network (WSN)

In day today’s life security is a very important thing in the world. For better achievement of security advanced technology have been undertaken in correctional facilities. Various security devices like CCTV, Tracking bracelets, ID barcode scanning and other devices have contributed to the improved and secure management. The aim of this paper is to invent a security system against prisoner by using RF Transmitter and receiver technology. It is based on RF Transmitter and Receiver technology on ultra high frequency range which can be applied to use in access control by using RF Transmitter and Receiver tag. The RF Transmitter and Receiver tag contains a unique set of number as a code, so it can be identified. The RF Transmitter will act as the bracelet and the RF Receiver will be at the server side. For keeping the track of prisoner Global Positioning System (GPS) is used. This technology can be used for monitoring the prisoners in the jail, patients in the hospitals or mental asylums who basically try to escape or run away from jails and mental asylums. It tracks the particular person wearing the bracelet within its range and as soon as it’s outside the range the GPS connected to the bracelet gets activated and we can track that particular person with the help of GPS on the bracelet. It’s also very useful in the schools for students and the staff, colleges, employees in the offices and etc where we need to keep track of someone’s presence. There is no need of keeping continuous watch due to this technology, for example if the prisoner runs away from the jail a message will be sent to the jailer and buzzer will ring. Due to this technique it will be easy for monitoring purpose.

WE-C-103-05: CT Scanning Protocol Quality Control Program: Development, Implement and Initial Experiences

Purpose: Frequent review of CT scanner protocols has been recognized as an important component to any CT quality control (QC) program, yet manual review is extremely labor-intensive and prone to human errors. The purpose of this study was to develop, implement and evaluate a software system to automatically monitor protocols on our CT scanners. Methods: A software system written in Matlab (MathWorks) and Excel Visual Basic (Microsoft) was developed to automatically check scanner CT protocols and notify designated users of changes on a weekly basis. The development team included medical physicists and lead technologists. Abdomen and pelvis protocols were monitored between December 2012 and February 2013 on two representative CT scanners for adult and pediatric, single-and dual-energy protocols. A total of 78 and 89 protocols were monitored on scanners 1 and 2, respectively. The overall workflow and number of errors identified were evaluated. Results: During the 2+ months monitoring period, 89 scanning protocols were modified on scanner 1, of which 20 were identified to be inappropriate (22%). 40 protocols were modified on scanner 2, of which 5 were identified to be inappropriate (13%). While the most frequent inappropriate modification was to the series description, errors were also found in changes to mAs, kernel, and reconstruction direction, increment and slice width. Conclusion: In routine clinical practice, CT protocols were found to be changed quite frequently. Thus, an automated protocol QC program is essential to ensure protocol accuracy and consistency. Use of access controls to limit the number of users able to modify protocols may help reduce the number of changes, but does not guarantee the accuracy of changes by authorized users. We successfully developed and implemented a software system to automatically monitor CT protocols that can be easily applied to a wide range of practices with negligible impact on workload.

A Survey of Delegation from an RBAC Perspective

Delegation in access control takes place in the presence of an access control model, when a user is unable to perform their administratively assigned permissions. In this paper, we discuss the meanings of the word “delegation” found in the literature, focusing on its use in access control. In the context of a rolebased access control model, we survey many possible ways in which delegation can be specified.

Automatic Personal Identification Using Feature Similarity Index Matching

Problem statement: Biometrics based personal identification is as an effective method for automatically recognizing, a person’s identity with high confidence. Palmprint is an essential biometric feature for use in access control and forensic applications. In this study, we present a multi feature extraction, based on edge detection scheme, applying Log Gabor filter to enhance image structures and suppress noise. Approach: A novel Feature-Similarity Indexing (FSIM) of image algorithm is used to generate the matching score between the original image in database and the input test image. Feature Similarity (FSIM) index for full reference (image quality assurance) IQA is proposed based on the fact that Human Visual System (HVS) understands an image mainly according to its low-level features. Results and Conclusion: The experimental results achieve recognition accuracy using canny and perwitt FSIM of 97.3227 and 94.718%, respectively, on the publicly available database of Hong Kong Polytechnic University. Totally 500 images of 100 individuals, 4 samples for each palm are randomly selected to train in this research. Then we get every person each palm image as a template (total 100). Experimental evaluation using palmprint image databases clearly demonstrates the efficient recognition performance of the proposed algorithm compared with the conventional palmprint recognition algorithms.

Multifeature-Based High-Resolution Palmprint Recognition

Palmprint is a promising biometric feature for use in access control and forensic applications. Previous research on palmprint recognition mainly concentrates on low-resolution (about 100 ppi) palmprints. But for high-security applications (e.g., forensic usage), high-resolution palmprints (500 ppi or higher) are required from which more useful information can be extracted. In this paper, we propose a novel recognition algorithm for high-resolution palmprint. The main contributions of the proposed algorithm include the following: 1) use of multiple features, namely, minutiae, density, orientation, and principal lines, for palmprint recognition to significantly improve the matching performance of the conventional algorithm. 2) Design of a quality-based and adaptive orientation field estimation algorithm which performs better than the existing algorithm in case of regions with a large number of creases. 3) Use of a novel fusion scheme for an identification application which performs better than conventional fusion methods, e.g., weighted sum rule, SVMs, or Neyman-Pearson rule. Besides, we analyze the discriminative power of different feature combinations and find that density is very useful for palmprint recognition. Experimental results on the database containing 14,576 full palmprints show that the proposed algorithm has achieved a good performance. In the case of verification, the recognition system's False Rejection Rate (FRR) is 16 percent, which is 17 percent lower than the best existing algorithm at a False Acceptance Rate (FAR) of 10(-5), while in the identification experiment, the rank-1 live-scan partial palmprint recognition rate is improved from 82.0 to 91.7 percent.

Prelaminates for contactless cards

Today, prelaminates are mainly used to manufacture PVC contactless cards for use in access control, banking and ticketing applications. However, there is an emerging application which will soon reach mass market proportions: secure ID, and in particular government-issued identity documents. These applications often require higher quality substrates that guarantee enhanced security and longer life, such as those based on polycarbonate and polyester.

Evaluation of Biometric Technologies for Access Control at Transportation Facilities and Border Crossings

To ensure that only authorized individuals–-legitimate workers, travelers, and visitors–-enter a transportation facility or border crossing, their identities must be ascertained. Because manual procedures are time-consuming, resource intensive, and vulnerable to human error and manipulation, the use of biometric technologies should be considered. This paper discusses several biometric technologies–-fingerprint recognition, iris recognition, facial recognition, and hand geometry–-and assesses their feasibility for use in access control at transportation facilities and border crossings. The advantages and disadvantages of the technologies are provided, as are cost, accuracy, and other performance data. Potential privacy and data issues are also discussed.
