This paper introduces a new concept called controllable ring signature which is ring signature with additional properties as follow. (1) Anonymous identifica-tion: by an anonymous identification protocol, the real signer can anonymously prove his authorship of the ring signature to the verifier. And this proof is non-transferable. (2) Linkable signature: the real signer can generate an anonymou...

This paper is aimed at ident ify ing the potent ial role of SPI CE, especially SPI CE level 3, to achieving the proposed UK public sector efficiencies. SPI CE level 3 presents the process m aturity fram ework to address the level I I I of the SPICE model. Building upon the developments of level I I , SPI CE 3 advocates establishment of a process improvement infrast ructure to facilitate good pr...

This document is intended to provide a first time user of I D E N T with tutorials on the usage of the program. The user should be familiar with the theoretical aspects of linear system identification. The Box and Jenkins (1976) Time Series Analysis is probably the best first reference. Following are explanations of each command (generated by IDENT), and examples of each command. I D E N T uses...

Automated border cont rol (ABC) is concerned with fast and secure processing for intelligence-led ident if icat ion. The FastPass proj ect aims to build a harmonised, modular reference system for future European ABC. When biometrics is taken on board as ident it y, spoofing at tacks become a concern. This paper presents current research in algorithm development for counter-spoofing at tacks in ...

To evaluate the accuracy of the MicroScan System (American Hospital Supply Corp., Sacramento, Calif.) for identification of coagulase-negative staphylococci, we tested 175 clinical isolates of coagulase-negative staphylococci. The results obtained by the MicroScan system were compared with those of the API Staph-Ident system (Analytab Products, Plainview, N.Y.). Forty-three discrepancies betwee...

An upward embedding of an embedded planar graph states, for ea h vertex v, whi h edges are in ident to v \above" or \below" and, in turn, indu es an upward orientation of the edges. In this paper we hara terize the set of all upward embeddings and orientations of a plane graph by using a simple ow model. We take advantage of su h a ow model to ompute upward orientations with the minimum number ...
