With recent advances in Internet and multimedia technology, the involvement of digital images in sexual offenses against women and children has been increasing significantly. These sexual offenses can be rapes, child sexual abuses and gang rapes. Even in one child sexual abuse case, evidence images and videos can be over 100 gigabytes. In Canada alone, Cybertip.ca received over 21,000 tips about online child exploitation between 2002 and 2008 and found 12,696 websites offering child sexual abuse images. Identifying criminals from this digital evidence can be very challenging because they are usually careful to hide or cover their faces and tattoos. All traditional biometric identification methods, e.g., faces, tattoos and fingerprints are not applicable to these evidence images. This talk will present a set of new computational methods for identifying criminals and victims in this digital evidence.
Dr. Adams Wai Kin Kong received the Ph.D. degree from the University of Waterloo, Canada. Currently, he is an associate professor at the Nanyang Technological University, Singapore. His papers have been published in TPAMI, TIP, TIFS, TSMC, TCSVT, CVPR and Pattern Recognition. One of his papers was selected as a spotlight paper by TPAMI and another one was selected as Honorable Mention by Pattern Recognition. With his students, he received best student paper awards in The IEEE Fifth International Conference on Biometrics: Theory, Applications and Systems, 2012 and IEEE International Conference on Bioinformatics and Bioengineering, 2013. In the summer of 2008, he served as an expert witness to the U.S. Department of Justice for a case of child sexual abuse. He is working closely with Singapore Police Force for a number of forensic projects. He has developed seven patents; four of his patents have been approved, and the others have been filed. His research interests include biometrics, forensics, image processing and pattern recognition.
