The student Shahad Fhadil has obtained her master's degree from the Department of Computer Sciences / University of Technology for her thesis titled "Electronic Crime for Identification of the Author of an Instant Message Using Viper". In this thesis, the researcher reached new technological methods of e-forensic to confront the continued anonymity and fraud, The anonymity of the Internet has made it difficult to trace criminal identity. Criminals use virtual characters to hide their real identities, in IM.
