We propose a novel method for fingerprint liveness detection, which is based on the analysis of fine movements of the fingertip surface, which are induced by volume changes due to the blood flow. Our method can be implemented in combination with standard optical fingerprint scanners. We present some background information on fingerprint liveness detection(More)
This paper deals with an SMS encryption for mobile communication. The transmission of an SMS in GSM network is not secure, therefore it is desirable to secure SMS by additional encryption. In the following text, there are compared differences in the use of symmetric and asymmetric cryptography for SMS transfer securing. In the next part, there is the(More)
This paper deals with the design of a biometric security system based upon the fingerprint and speech technology. In the first chapter there are the biometric security systems and a concept of an integration of the both technologies introduced. Then the fingerprint technology followed by the speech technology is shortly described. There are discussed some(More)
This paper deals with an add-on for biometric security systems, especially for the fingerprint recognition technology. This added part of such systems is the liveness detection. Our method is based on detection of optical characteristics of the finger surface (skin). The main idea is to detect the movements of papillary lines, but some another optical(More)
This paper deals with a description of wireless sensor networks at the beginning. Further follows the introduction to the agent platform suitable for wireless networks. Mobile code and sensor networks suffer from considerable security problems. Our proposal of countermeasure is based on combination of smartcards with sensor nodes. Smartcards as a tamper(More)
Travelling is becoming available for more and more people. Millions of people are on a way every day. That is why a better control over global human transfer and a more reliable identity check is desired. A recent trend in a field of personal identification documents is to use RFID (Radio Frequency Identification) technology and biometrics, especially (but(More)
