SCAN-based compression-encryption-hiding for video on demandSCAN-based compression-encryption-hiding for video on demand Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-022003enWe present a SCAN-based method for image and video compression-encryption-hiding with application to digital video on demand. The software SCAN implementation running on a Pentium IV takes about 1 second for 25 video frames. As an alternative solution, however, we have developed a FPGA-based architecture, which operates in real time.http://creativecommons.org/licenses/by/4.0/IEEE MultiMedia10379-87 Dollas Apostolos Δολλας Αποστολος Bourbakis, Nikolaos G Institute of Electrical and Electronics Engineers Video on demand Cryptography Image coding Video compression Discrete wavelet transforms Dictionaries Transform coding Wavelet transforms Chaotic communication Context
