%0 Journal Article %J Image Processing (ICIP) %D 2010 %T Security analysis for privacy preserving search of multimedia %A Lu,W. %A Varna,A.L. %A Wu,M. %X With the increasing popularity of digital multimedia such asimages and videos and the advent of the cloud computing paradigm, a fast growing amount of private and sensitive mul- timedia data are being stored and managed over the network cloud. To provide enhanced security and privacy protection beyond traditional access control techniques, privacy preserv- ing multimedia retrieval techniques have been proposed re- cently to allow content-based multimedia retrieval directly over encrypted databases and achieve accurate retrieval com- parable to conventional retrieval schemes. In this paper, we introduce a security definition for the privacy preserving re- trieval scenario and show that the recently proposed schemes are secure under the proposed security definition. %B Image Processing (ICIP) %P 26 - 29 %8 2010/// %G eng
