  • Most of the sources of security and privacy issues in RFID technology arise from the violation of the air interface between a tag and its read. Most of the sources of security and privacy issues in RFID technology arise from the violation of the air interface between a tag and its reader. This paper will approach consideration of security analysis with cryptographic primitive based on hardware basis.

  • Using carefully assembled sets of IDs based on the cryptographic principle of secret shares, we can create RFID tags that yield virtually no information to casual "hit-and-run" attackers, but only reveal their true ID after continuous and undisturbed reading from up-close something that can hardly go unnoticed by an item's owner. In this paper, we analyses the practical issues of cryptography for RFID privacy with lightweight method.

  • Internet-based distribution of digital contents provides great opportunities for producers, distributors and consumers, but it may seriously threaten users' privacy. The Digital Rights Management (DRM) systems which one of the major issues, concern the protection of the ownership/copyright of digital content. However, the most recent DRM systems do not support the protection of the user's personal information. This paper examines the lack of privacy in DRM systems. We describe a privacy policy and user's privacy preferences model that protect each user's personal information from privacy violation by DRM systems. We allow DRM privacy agent to automatically negotiate between the DRM system policy and user's privacy preferences to be disclosed on behalf of the user. We propose an effective negotiation algorithm for the DRM system. Privacy rules are created following the negotiation process to control access of the user's personal information in the DRM system. The proposed privacy negotiation algorithm can be adapted appropriately to the existing DRM systems to solve the privacy problem effectively.

  • 본 논문에서는 난수 기반의 ID를 동적으로 RFID 태그에 부여함으로써 태그의 ID 추적으로 인해 태그 소유자의 프라이버시가 침해당할 소지를 제거할 수 있는 RFID 시스템을 제안한다. 현재 RFID 시스템의 취약한 문제점으로 사생활 침해의 문제가 대두되고 있다. 이는 RFID 태그에 저장되는 ID를 추적함으로써 발생하고 있으며 본 논문에서는 이러한 문제점을 방지하기 위해 태그에 난수 기반의 ID를 필요할 때마다 동적으로 할당함으로써 ID 추적이 불가능한 RFID 시스템을 제안한다. 이러한 시스템은 대형 할인매장에서 손님들에게 태그를 나누어 주고 프라이버시를 보호하면서 그 이동 경로를 추적하여 고객정보를 축적하는 RFID 시스템에 적용할 수 있다.

  • This study focuses on the antecedents to the privacy concerns and their influence on trust and online transaction intention. Based on previous exploratory works and the literature review of privacy concerns, four antecedents are identified-Internet literacy, social awareness, perceived vulnerability, and perceived ability to information control. Incorporating these antecedents, privacy concerns, trust and online transaction intention, a conceptual model is developed and seven research hypotheses are proposed for empirical testing. The proposed model is examined through structural equation analysis. The results show that Internet literacy, social awareness, and perceived vulnerability have statistically significant effect on the privacy concerns of users and the privacy concerns has a positive influence on the trust. Finally, the trust has a positive effect on the online transaction intention. Implications of these findings are discussed for both researchers and practitioners and future research issues are raised as well.

  • Personal Identifiable Information (PII) is considered information that identifies or can be used to identify, contact, or locate a person to whom such information pertains or that is or might be linked to a natural person directly or indirectly. In order to recognize such data processed within information and communication technologies such as PII, it should be determined at which stage the information identifies, or can be associated with, an individual. For this, there has been ongoing research for privacy protection mechanism to protect PII, which now becomes one of hot issues in the International Standard as privacy framework and privacy reference architecture. Data processing flow models should be developed as an integral component of privacy risk assessments. Such diagrams are also the basis for categorizing PII. The data processing flow may not only show areas where the PII has a certain level of sensitivity or importance and, as a consequence, requires the implementation of stronger safeguarding measures. This paper propose a standard format for satisfying the ISO/IEC 29100 "Privacy Framework" and shows an implementation example for privacy reference architecture implementing privacy controls for the processing of PII in information and communication technology.

  • The objective of this study was to discuss child privacy issues at Web sites targeting children, Specifically, the study examined l)types of information required for join the membership, 2)whether privacy policies at Web sites for children abide by privacy guideline, and 3)specific examples of recommendable privacy policy and problematic privacy policy from Web sites, Total of 305 Web sites targeting children were used for content analysis, Selected Web sites included recommended sites by Korea Council of Children's Organizations and food business Web sites, The results showed that more than 70% of Web sites required private information when children join the membership. Most of these Web sites provided mailing service for children. Generally, Web sites showed problems in parents' approval procedures. Also, privacy policies at Web sites frequently omitted purpose specification principle and the security safeguard principle. Regulating online service provides and marketers targeting children would be necessary for protecting child privacy. Further, education program targeting parents and children could help them make right choices to protect children's online privacy.

  • Radio Frequency Identification (RFID) is a technology for automated identification of objects and people. RFID may be viewed as a means of explicitly labeling objects to facilitate their "perception" by computing devices. RFlD systems have been gaining more popularity in areas especially in supply chain management and automated identification systems. However, there are many existing and potential problems in the RFlD systems which could threat the technology s future. To successfully adopt RFID technology in various applications. we need to develop the solutions to protect the RFID system s data information. This study investigates important issues related to privacy and security of RF1D based on the recent literature and suggests solutions to cope with the problem.

  • With the wide deployment of biometric authentication systems, several issues pertaining security and privacy of the biometric template have gained great attention from the research community. To resolve these issues, a number of biometric template protection methods have been proposed. However, the design of a template protection method to satisfy four criteria, namely diversity, revocability and non-invertibility is still a challenging task, especially performance degradation when template protection method is employed. In this paper, we propose a novel method to generate a revocable minutiae-based fingerprint template. The proposed method consists of feature extraction from fingerprint minutiae pairs, quantization, histogram binning, binarization and eventually binary bit-string generation. The contributions of our method are two fold: alignment-free and good performance. Various experiments on FVC2004 DB1 demonstrated the effectiveness of the proposed methods.

  • The technical definition of Blockchain is commonly known 'distributed ledger', however, there is no legal definition for being accepted in worldwide. Therefore, unless legal definitions and concepts of Blockchain are presented, there is a possibility that various legal disputes will occur in the future in Blockchain environment. The purpose of this study is to derive legal issues related to personal information protection that can be conflicted in Blockchain environment based on domestic Privacy Act and GDPR. The outcomes of this study can prevent various legal disputes and provide solutions that may occur due to the spread of Blockchain. It also suggests the foundation for the improvement of Privacy Act. Finally, it contributes to activate of Blockchain, industry, in Korea.
