The rising popularity of social networks and cloud computing has greatly increased a
number of JPEG compressed image exchanges. In this context, the security of the …

Repeated rounding of sample blocks in alternating domains creates complex convergence
paths. We study convergence and block stability for JPEG images compressed with quality …

JPEG-compatibility steganalysis detects the presence of embedding changes using the fact
that the stego image was previously JPEG compressed. Following the previous art, we work …

Forensic investigators sometimes need to verify the integrity and processing history of digital
photos and videos. The multitude of storage formats and devices they need to access also …

Given a JPEG pipeline (compression or decompression), this paper shows how to find the
antecedent of a 8 x 8 block. If it exists, the block is compatible with the pipeline. For …
