A study on the use of perceptual hashing to detect manipulation of embedded messages in images. (arXiv:2303.00092v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Typically, metadata of images are stored in a specific data segment of the
image file. However, to securely detect changes, data can also be embedded
within images. This follows the goal to invisibly and robustly embed as much
information as possible to, ideally, even survive compression.
This work searches for embedding principles which allow to distinguish
between unintended changes by lossy image compression and malicious
manipulation of the embedded message based on the change of its perceptual or
robust hash. …
