We introduce and analyze a randomized traitor tracing algorithm for broadcast security. This algorithm is very efficient compared to brute force methods (the mean time it takes is...
Abstract. In the future it is likely that peer communities will be routinely established for the purpose of sharing electronic resources and targeted information among groups of pe...
Computer vision applications are able to model and reconstruct three dimensional scenes from several pictures. In this work, we are interested in the group of algorithm that regis...
