Jessica Fridrich’s main research areas are steganography, the science (and art) of message hiding, and the forensics of digital multimedia. Professor Fridrich is viewed by her peers as a “superstar” and the world’s foremost authority in the field of steganography. In 2009, in addition to her many research papers, she published “Steganography in Digital Media: Principles, Algorithms, and Applications,” (Cambridge University Press) which has rapidly become the seminal graduate textbook in steganography. In the area of forensics, she has developed a now patented method for “finger printing” digital photos so that photos can be reliably linked with a camera. Her method is the only one that has been officially approved (it has passed the Daubert Challenge) for use as evidence in forensics cases in a court of law. In total, Fridrich’s research has resulted in over 150 refereed publications, with over 16,000 citations, and seven patents, all of which have been successfully commercialized.
