This book presents to the readers the basics of Digital Forensics; why this domain is gaining rapid importance in the present day. We clarify the difference of this domain of research, from traditional security measures; specifically the additional challenges that digital forensic techniques are able to overcome, as compared to the olden techniques of cryptography, watermarking and steganography. In the book, we discuss about the most important challenges faced by forensic analysts in the present day, along with the state-of-the-art solutions. We also present the recent challenges identified in this field, while paving a path for possible future researches towards solving those.…
