This paper explores the connection between forensics, counterforensics, steganography and adversarial images. On the one hand, forensicsbased and steganalysis-based detectors help in detecting adversarial perturbations. ...

Group membership verification checks if a biometric trait corresponds to one member of a group without revealing the identity of that member. Recent contributions provide privacy for group membership protocols through th...

This paper proposes a group membership verification protocol preventing the curious but honest server from reconstructing the enrolled signatures and inferring the identity of querying clients. The protocol quantizes the...

This paper considers watermarking detection, also known as zero-bit watermarking. A watermark, carrying no hidden message, is inserted in content. The watermark detector checks for the presence of this particular weak si...

This second part focuses on estimation of secret parameters of some practical watermarking techniques. The first part reveals some theoretical bounds of information leakage about secret keys from observations. However, a...

Dans ce chapitre, le concept de tatouage asymétrique est introduit de façon simple et pédagogique. Tout d'abord, deux applications se servant du tatouage numérique dans un système de protection sont brièvement décrites. ...

In spread-spectrum watermarking, the watermarked document is obtained from the addition of an attenuated watermark signal to a cover multimedia document. A traditional strategy consists of optimising the detector for a g...
