AngelFingerprint: A Traceable, Explainable, and White-Box Stealthy Watermark for Text-Guided Image Editing

Text-guided diffusion editing raises disinformation concerns, making reliable image provenance essential. While watermarks are commonly used for this purpose, most methods carry a fixed ID that cannot explain what was changed and which prompt produced it. Furthermore, under open-source white-box access, attackers can e...

Personalizing LLM Agent Memory Using Biometrics

Bio-Memory is proposed, a biometric-aware memory architecture that conditions memory retrieval on both semantic similarity and biometric matching and augments each atomic memory note with a biometric embedding and uses biometric matching to form the retrieval candidate pool before semantic ranking.

Retrosynthesis of Synthetic Media for Explainable AI Provenance Forensics

A self-referential retrosynthesis framework for explainable AI provenance forensics under a fixed-generator setting that leverages a jointly optimized encoder-decoder pair to implement a self-embedding mechanism that enables round-trip consistency verification.
