We propose a model and definition for anonymous (group) identification that is well suited for RFID systems. This is based on the definition of Juels and Weis of strong privacy for RFID tags, where we add requirements for completeness and soundness. We also propose a weaker and more realistic definition of privacy. For the case where tags hold independent keys, we prove a conjecture by Juels an...

Extracting minutiae from fingerprint images is one of the most important steps in automatic fingerprint identification system. Because minutiae matching are certainly the most well-known and widely used method for fingerprint matching, minutiae are local discontinuities in the fingerprint pattern. In this paper a fingerprint matching algorithm is proposed using some specific feature of the minu...

The factorization problem in non-abelian groups is still an open and a difficult problem [12]. The hardness of the problem is illustrated by the moves of the Rubik’s cube. We will define a public key identification scheme based on this problem, in the case of the Rubik’s cube, when the number of moves is fixed to a given value. Our scheme consists of an interactive protocol which is zero-knowle...

RFID applications do not always use encryption to ensure the security as public key cryptographic algorithms that are costly in term of computing resources. We proposed to secure the communication from an ISO 14443 RFID card to the reader against passive eavesdropping at the physical layer by adding noise. During the card reply, the reader generates an appropriate noise that is modulated by the...

Presented here is an alternative method of identification for species of the Neotropical palm genus Syagrus. It makes use of anatomical characters found in the leaflet margins and can be used for identification when few other vegetative or reproductive morphological characters are available. This anatomical study demonstrates the vast diversity found in a single palm genus and may also help to ...

Im Forschungsprojekt Navigation, Vermessung und Kennzeichnung in der Rundholzlogistik wurde ein RFID-basiertes System entwickelt, das eine automatisierte einzelstammweise Kennzeichnung von Rundholz ermöglicht. Damit ist ein wesentlicher Schritt für ein umfassendes Controlling der Holzernteund Bereitstellungsprozesse und zur Sicherstellung waldbesitzerscharfer Abrechnung des aufgearbeiteten Rohh...
