It is also multi-scheme, because it allows to have on the same server different types of micropayment schemes. The framework has been designed...
In this paper is presented an extended experimental evaluation of one of the most effective source camera identification techniques proposed so far, by Lukáš et al. (IEEE Trans Inf Forensics Security 1(2):205–214, 2006). This method uses the characteristic noise left by the sensor on a digital picture as a fingerprint in order to identify the source camera used to take the picture. The aim of the...
