ProxyEraseAgent: Blind Watermark Removal in the Wild
ProxyEraseAgent recovers blind watermarks by using a knowledge base of public watermarking systems to find 'proxy decoders.' It ranks these decoders based on their response to an input image and then uses their feedback to plan an adaptive, multi-step attack path. This method successfully removes watermarks with a 94.8% success rate across 11 different systems, showing that external feedback can guide removal when the target decoder is unknown.
