Christine Yurie Kim Eminent Professor of Information Technology and Associate Chair for Graduate Studies and Research Dr. K.J. Ray Liu delivered a keynote speech at the Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC 2011) in Xi’an, China. Held on October 18-21, ASPIPA ASC aims to promote research and education on signal processing, information technologies and communications.  

Dr. Liu’s talk was titled, “Information Anti-Forensics”, and discussed a variety of anti-forensic operations, in particular several anti-forensic techniques designed to remove evidence of an image’s compression history.  These techniques are used to perform a number of image tampering operations such as double compression, cut-and-paste image forgery, and image origin falsification, which render the changes forensically undetectable. 

The rise of the Internet coupled with the widespread availability of digital cameras and audio recorders has created an environment in which society relies heavily on digital multimedia content when communicating information.  Because digital content is easily manipulated, a number of forensic techniques have been developed to verify the authenticity of multimedia content. By contrast, very little consideration has been given to anti-forensic operations capable of disguising evidence of multimedia tampering.  The study of anti-forensics is critically important to digital information security and assurance because it creates awareness of vulnerabilities in existing forensic techniques, which digital forgers may attempt to secretly exploit. 

The APSIPA is an annual conference that began in 2009 and was held in Japan and Singapore in previous years. The scope of APSIPA concerns all aspects of signals and information including processing, recognition, classification, communications, networking, computing, system design, security, implementation, and technology with applications to scientific, engineering, and social areas. APSIPA ASC 2011 was sponsored by Northwestern Polytechnical University, Shaanxi Provincial Key Laboratory of Speech & Image Information Processing (SAIIP), d-Ear Technologies, SNDA, Dolby Laboratories, and the Chinese Information Processing Society of China.
