The proliferation of AI-generated content (AIGC) has facilitated sophisticated face manipulation, severely undermining visual integrity and posing unprecedented challenges to intellectual property (IP). In response, a common proactive defense leverages fragile watermarks to detect, localize, or even
The intellectual property of deep generative networks (GNets) can be protected using a cascaded hiding network (HNet) which embeds watermarks (or marks) into GNet outputs, known as box-free watermarking. Although both GNet and HNet are encapsulated in a black box (called operation network, or ONet),
The intellectual property of deep image-to-image models can be protected by the so-called box-free watermarking. It uses an encoder and a decoder, respectively, to embed into and extract from the model's output images invisible copyright marks. Prior works have improved watermark robustness, focusin…
Recent research has shown that an adversary can use a surrogate model to steal the functionality of a target deep learning model even under the black-box condition and without data curation, while the existing defense mainly relies on API poisoning to disturb the surrogate training. Unfortunately, d…
Most of the artificial lights fluctuate in response to the grid's alternating current and exhibit subtle variations in terms of both intensity and spectrum, providing the potential to estimate the Electric Network Frequency (ENF) from conventional frame-based videos. Nevertheless, the performance of…
Blind source separation involves the estimation of mixing matrix given only observed mixtures. Considering the computational cost in practice, this paper proposes an efficient mixing matrix estimation (MME) method using an easily configured two-sensor array. Time-frequency (TF) analysis, which has b…
This paper presents a robust design of the transmit beampattern for uniform linear antenna arrays. Existing designs are usually completed at the stage of achieving an optimal transmit covariance matrix from identifying a weighting matrix with the assumption of ideally orthogonal waveforms. However,…
