Raising Security of Fingerprint Biometric Systems- using Advanced Encryption Scheme
Securing biometrics databases from being compromised is major challenge, it must be overcome in order to support widespread use of biometrics based authentication. In this paper we present a cryptographic technique for enhanced security of fingerprint information using RC4 enrichment algorithm approach. RC4 algorithm is already used for image encryption. This paper is about encryption and decry...

In De Kuthy and Meurers (1998, 1999b) we showed that such cases of partial constituent fronting can successfully be an...
متن کاملBack and Forward Moving Scheme of Front Wheel Raising for Inverse Pendulum Control Wheel Chair Robot
A power assist wheel chair robot by which a patient can climb over steps/curbs without any helper's assistance is proposed. A patient can maintain inverse pendulum control of the wheel chair after raising its front wheels. Next, a patient can move to the step maintaining the inverse pendulum control, and can climb over the step being assisted by DC motor force. A light weight wheel chair system...
متن کاملRaising tibet.
Thermochronologic, sedimentologic, oceanographic, and paleoclimatic studies suggest that rapid uplift and unroofing of southern Tibet began about 20 million years ago and that the present elevation of much of the Tibetan plateau was attained by about 8 million years ago. Hypotheses advanced to explain the tectonic evolution of the India-Asia collision, which began about 40 to 50 million years a...
