RFID based systematic student's attendance management system

Most educational institutions’ administrators are concerned about student irregular attendance. Truancies can affect student overall academic performance. The conventional method of taking attendance by calling names or signing on paper is very time consuming and insecure, hence inefficient. Therefore, computer-based student attendance management system is required to assist the faculty and the lecturer for this time-consuming process. For this project, RFID based systematic student’s attendance management system can provide much convenient method to take attendance, but some prerequisites has to be done before start using the program. Although the use of RFID systems in educational institutions is not new, it is intended to show how the use of it came to solve daily problems in our university. Assisted by the System Development Life Cycle (SDLC) methodology, the system has been built using the web-based applications such as JSP, MySQL and Apache to cater the recording and reporting of the students’ attendances. NetBeans IDE 6.1 is used for developing the overall system, MySQL as the database and Java act as the scripting programming language. RFID Based Systematic Student’s Attendance Management System was built using open source software and it will reduce the cost of development process. The system can be easily accessed by the lecturers via the web and most importantly, the reports can be generated in real-time processing, thus, providing valuable information about the students’ commitments in attending the classes

AnonPri: A Secure Anonymous Private Authentication Protocol for RFID Systems

Privacy preservation in RFID systems is a very important issue in modern day world. Privacy activists have been worried about the invasion of user privacy while using various RFID systems and services. Hence, significant efforts have been made to design RFID systems that preserve users\u27 privacy. Majority of the privacy preserving protocols for RFID systems require the reader to search all tags in the system in order to identify a single RFID tag which not efficient for large scale systems. In order to achieve high-speed authentication in large-scale RFID systems, researchers propose tree-based approaches, in which any pair of tags share a number of key components. Another technique is to perform group-based authentication that improves the tradeoff between scalability and privacy by dividing the tags into a number of groups. This novel authentication scheme ensures privacy of the tags. However, the level of privacy provided by the scheme decreases as more and more tags are compromised. To address this issue, in this paper, we propose a group based anonymous private authentication protocol (AnonPri) that provides higher level of privacy than the above mentioned group based scheme and achieves better efficiency (in terms of providing privacy) than the approaches that prompt the reader to perform an exhaustive search. Our protocol guarantees that the adversary cannot link the tag responses even if she can learn the identifier of the tags. Our evaluation results demonstrates that the level of privacy provided by AnonPri is higher than that of the group based authentication technique

A Privacy Preserving Framework for RFID Based Healthcare Systems

RFID (Radio Frequency IDentification) is anticipated to be a core technology that will be used in many practical applications of our life in near future. It has received considerable attention within the healthcare for almost a decade now. The technology’s promise to efficiently track hospital supplies, medical equipment, medications and patients is an attractive proposition to the healthcare industry. However, the prospect of wide spread use of RFID tags in the healthcare area has also triggered discussions regarding privacy, particularly because RFID data in transit may easily be intercepted and can be send to track its user (owner). In a nutshell, this technology has not really seen its true potential in healthcare industry since privacy concerns raised by the tag bearers are not properly addressed by existing identification techniques. There are two major types of privacy preservation techniques that are required in an RFID based healthcare system—(1) a privacy preserving authentication protocol is required while sensing RFID tags for different identification and monitoring purposes, and (2) a privacy preserving access control mechanism is required to restrict unauthorized access of private information while providing healthcare services using the tag ID. In this paper, we propose a framework (PriSens-HSAC) that makes an effort to address the above mentioned two privacy issues. To the best of our knowledge, it is the first framework to provide increased privacy in RFID based healthcare systems, using RFID authentication along with access control technique

Product Authentication Using Hash Chains and Printed QR Codes

This thesis explores the usage of simple printed tags for authenticating products. Printed tags are a cheap alternative to RFID and other tag based systems and do not require specialized equipment. Due to the simplistic nature of such printed codes, many security issues like tag impersonation, server impersonation, reader impersonation, replay attacks and denial of service present in RFID based solutions need to be handled differently. An algorithm that utilizes hash chains to secure such simple tags while still keeping cost low is discussed. The security characteristics of this scheme as well as other product authentication schemes that use RFID tags are compared. Arguments for static tags being at least as secure as RFID tags is discussed. Finally, a scheme for combining RFID authentication with static tags to achieve security throughout the supply chain is discussed

Computação massivamente paralela para identificação de marcadores RFID

Mestrado em Engenharia de Computadores e TelemáticaNos dias que correm, tem-se assistido a uma grande evolução dos sistemas de identificação através de marcadores RFID, frequentemente sem se dar a devida importância à componente de privacidade nos mesmos. A presente dissertação pretende explorar um paradigma de identificação de marcadores com o intuito de colmatar esta lacuna, recorrendo à utilização de uma função dificilmente invertível, criptográfica ou de síntese, para a geração no marcador de um identificador pseudo-aleatório a partir do identificador real do mesmo, bem como de um conjunto de números aleatórios gerados pelo marcador e pelo leitor. Contudo, torna-se necessária uma pesquisa ao longo de todos os identificadores atribuídos, que por questões de desempenho é realizado de uma forma massivamente paralela. Desta forma, impede-se o seguimento de objectos ou pessoas associados ao marcador por entidades Ilegítimas, que não tenham acesso a uma base de dados de todos os identificadores atribuídos.In recent years, there has been a large evolution of identification systems through the use of RFID tags, often with some disregard for privacy concerns. In this dissertation a paradigm will be explored focusing on the use of a well known cryptographic standard or hashing function to generate a pseudo-random identifier from the real identifier as well as a set of random nonces from the tag and reader. However, a search is required along the set of assigned identifiers, which for the sake of performance shall be done resorting to a massively parallel approach. This way, it becomes unfeasible for an illegitimate reader to relate two activation sessions of the same tag without access to the database of all the assigned identifiers

Providing Security and Privacy in RFID Systems Using Triggered Hash Chains

RFID technology shall increase security, e.g. by helping to prevent counterfeiting. But the tech-nology also causes privacy issues. In this paper, after highlighting goals and problems, an ap-proach called “Triggered Hash Chains ” is pro-posed to address the problems. The approach combines concepts of two very different, widely known RFID protocols, i.e. the “Hash-based ID variation ” approach and the “Hash chain ” ap-proach. The resulting proposal joins the advan-tages of both protocols. The approach is evaluated using a variety of criteria that are rele-vant in practice

Ensuring Application Specific Security, Privacy and Performance Goals in RFID Systems

Radio Frequency IDentification (RFID) is an automatic identification technology that uses radio frequency to identify objects. Securing RFID systems and providing privacy in RFID applications has been the focus of much academic work lately. To ensure universal acceptance of RFID technology, security and privacy issued must be addressed into the design of any RFID application. Due to the constraints on memory, power, storage capacity, and amount of logic on RFID devices, traditional public key based strong security mechanisms are unsuitable for them. Usually, low cost general authentication protocols are used to secure RFID systems. However, the generic authentication protocols provide relatively low performance for different types of RFID applications. We identified that each RFID application has unique research challenges and different performance bottlenecks based on the characteristics of the system. One strategy is to devise security protocols such that application specific goals are met and system specific performance requirements are maximized. This dissertation aims to address the problem of devising application specific security protocols for current and next generation RFID systems so that in each application area maximum performance can be achieved and system specific goals are met. In this dissertation, we propose four different authentication techniques for RFID technologies, providing solutions to the following research issues: 1) detecting counterfeit as well as ensuring low response time in large scale RFID systems, 2) preserving privacy and maintaining scalability in RFID based healthcare systems, 3) ensuring security and survivability of Computational RFID (CRFID) networks, and 4) detecting missing WISP tags efficiently to ensure reliability of CRFID based system\u27s decision. The techniques presented in this dissertation achieve good levels of privacy, provide security, scale to large systems, and can be implemented on resource-constrained RFID devices
