Content-adaptive steganography constrains its embedding changes to those parts of covers that are difficult to model, such as textured or noisy regions. When combined with advanced coding techniques, adaptive steganographic methods can embed rather large payloads with low statistical detectability at least when measured using feature-based steganalyzers trained on a given cover source. The rece...

This document describes RMX, a simple message randomization scheme that when used as a front end to existing hash-then-sign signature schemes, such as RSA and DSS, frees these signatures from their current vulnerability to off-line collision attacks on the underlying hash function. We demonstrate the practicality of the approach, which requires no change to hash functions or signature algorithm...
