Recently, splicing detection, another important area in digital forensics has attracted increasing attention. Is there any relationship between steganalysis and splici

The scheme utilises Message Authentication Codes (MAC), specifically OMACs, which create a cryptographic fixed-length summary of a document. An OMAC must be truncated to a form part of our watermark and is used during authentication. The re

This proposed scheme utilizes the local spatial correlation of neighboring quantized VQ indices to conceal secret data under image coded stream and achieve data reversibility simultaneously.

https://doi.org/10.1057/9781137464750The compositing of two or more people into a single image is a common form of manipulation. We describe how such composites can be detected by estimating a camera’s intrinsic parameters from the image of a person’s eyes. Differences in these parameters across the image are used as evidence of tampering.

https://doi.org/10.1057/9781137010353We analyze the security of a fingerprinting scheme proposed at IWDW 2005. We show two results, namely that this scheme (1) does not provide .: a dishonest buyer can repudiate the fact that he redistributed a content, and (2) does not provide .: a buyer can be framed by a malicious seller.

Early Modern Literature in HistoryThis paper reviews techniques for binary images data hiding and watermarking and proposes a general framework for authentication purposes. Finally, a multi-level signature scheme is presented, which is effective to detect malicious tamperings conducted to an image.
