Anti-Spoof Reliable Biometry of Fingerprints Using En-Face Optical Coherence Tomography

Optical coherence tomography (OCT) is a relatively new imaging technology which can produce high-reso- lution images of three-dimensional structures. OCT has been mainly used for medical applications such as for ophthalmology and dermatology. In this study we demonstrate its capability in providing much more re- liable biometry identification of fingerprints than conventional methods. We prove that OCT can serve se- cure control of genuine fingerprints as it can detect if extra layers are placed above the finger. This can pre- vent with a high probability, intruders to a secure area trying to foul standard systems based on imaging the finger surface. En-Face OCT method is employed and recommended for its capability of providing not only the axial succession of layers in depth, but the en-face image that allows the traditional pattern identification. Another reason for using such OCT technology is that it is compatible with dynamic focus and therefore can provide enhanced transversal resolution and sensitivity. Two En-Face OCT systems are used to evaluate the need for high resolution and conclusions are drawn in terms of the most potential commercial route to ex- ploitation

Using biometrics authentication via fingerprint recognition in e-Exams in e-Learning environment

E-learning is a great opportunity for modern life. Notably, however, the tool needs to be coupled with efficient and reliable security mechanisms to ensure the medium can be established as a dependable one. Authentication of e-exam takers is of prime importance so that exams are given by fair means. A new approach shall be proposed so as to ensure that no unauthorised individuals are permitted to give the exams

Gait Verification using Knee Acceleration Signals

A novel gait recognition method for biometric applications is proposed. The approach has the following distinct features. First, gait patterns are determined via knee acceleration signals, circumventing difficulties associated with conventional vision-based gait recognition methods. Second, an automatic procedure to extract gait features from acceleration signals is developed that employs a multiple-template classification method. Consequently, the proposed approach can adjust the sensitivity and specificity of the gait recognition system with great flexibility. Experimental results from 35 subjects demonstrate the potential of the approach for successful recognition. By setting sensitivity to be 0.95 and 0.90, the resulting specificity ranges from 1 to 0.783 and 1.00 to 0.945, respectively

The fusion of law and information technology

In information society, legal norm communications have been never established in certain fields for a long time. That is, a few legal norms have never obeyed in the fields. Above all, legal norms which relate to data protection, information contents and information security, would often infringed. Most violation would be conducted by using information technologies. Information technologies would often be used in these infringing incidents. It can be said that these infringing incidents would have never been conducted without information technology. These infringing incidents include hacking actions, personal data abuse, personal information disclosure, unauthorized access, infringing copyrights, infringing privacy rights, and so on. A way of preventing those infringements is to raise the level of punishment against the violators. But, it will prove to be disappointing. Furthermore, it would be an ex post facto measure to the last. It would be needed to invent an ex ante measure, if it is possible. As the ex ante measure, the author proposes a fusion of law and information technology. An information technology will lead people to a lawful deed when they conduct actions in using computers and networks. They say that information technology cures information technology. After all, the fusion will aim at realizing laws, and it will contribute to recover a social justice
