New method embeds information in AI policy randomness

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a novel method called posterior-matching randomness modulation (PRAM) to embed information within the random actions of a stochastic policy in Markov Decision Processes (MDPs). This technique allows information to be communicated implicitly by modulating action realizations without changing the overall action distribution. PRAM is framed as a channel coding problem and is proven to be asymptotically reliable, enabling message decoding with minimal error as state trajectories lengthen. The paper demonstrates PRAM's utility in applications such as multi-bit policy watermarking and trajectory provenance. AI

IMPACT Introduces a novel technique for implicit communication in AI policies, potentially enhancing security and traceability of AI models.

    Embedding Information in Policy Randomness: Distribution-Preserving Implicit Communication in MDPs

    arXiv:2610.15976v1 Announce Type: cross Abstract: This paper investigates a new role of randomness in stochastic policies--as a medium for embedding and communicating information. Specifically, we consider an agent interacting with an environment according to a prescribed stochas…
