The MIFARE Classic is the most popular RFID chip, used in public transport as well as cafeterias and other applications. This paper gives an overview of which methods were used to re-engineer the chips, from polishing to analyzing the communication. Within this process, various security weaknesses were discovered. Those allow various attacks, which will be shown in the last part of the paper.

This paper describes a metal mount RFID tag that works reliably on metallic surfaces. The method proposes the use of commercial label type RFID tags with 2.5 mm thick Styrofoam103.7 with a relative permittivity of 1.03 attached on the back of the tag. In order to verify the performance of the proposed method, we performed experiments on an electric transformer supply chain system. The experimen...

In this paper we discuss how to reduce identification time with a given number of tags in the field of an RFID reader. This paper proposes three methods for fast tag identification: bi-slotted tree based RFID tag anti-collision protocols, query tree based reservation, and the combining method of them. Theses proposed methods can be used for enhancing the identification speed of RFID systems.

AN RFID BASED UBIQUITOUS FRAMEWORK FOR MOBILE OBJECT TRACKING

The robust development of Electronic Health Records (EHRs) causes a significant growth in sharing EHRs for clinical research. However, such a sharing makes it difficult to protect patients’ privacy. A number of automated de-identification tools have been developed to reduce the re-identification risk of published data, while preserving its statistical meanings. In this paper, we focus on the ex...

This paper deals with multiobjective nonlinear system identification applied when modelling the relation of firing angle and equivalent reactance of a thyristor controlled series capacitor (TCSC). The mathematical representation chosen is NARMAX (Nonlinear AutoRegressive Moving Average with eXogenous inputs) due to its capability in modelling nonlinear systems and in using prior information. Th...

Previous approaches to the task of native language identification (Koppel et al., 2005) have been limited to small, within-corpus evaluations. Because these are restrictive and unreliable, we apply cross-corpus evaluation to the task. We demonstrate the efficacy of lexical features, which had previously been avoided due to the within-corpus topic confounds, and provide a detailed evaluation of ...
