Concurrency and Computation: Practice and Experience, Volume 38, Issue 15, August 2026.ABSTRACT This paper presents MusicoCrypt, a context‐bound music‐modulated stream‐encryption framework that incorporates audio‐derived public side information into a pseudorandom‐function‐centered encryption workflow. A shared reference recording is processed using a pitch‐tracking pipeline, and ordered note pairs are encoded as residues in ℤ132 ...

An Approximate Schur Decomposition-Based Spatial Domain Color Image Watermarking Method
IEEE Access, 2019 In this paper, an approximate Schur decomposition-based spatial domain blind color image watermarking method is proposed to protect the copyright of color images, which has low computation complexity similiar to the watermarking technique in the spatial ...

Secure Decentralized Key Relaying via Random Walks in Dynamic Semi‐Trusted QKD Networks
Advanced Quantum Technologies, Volume 9, Issue 8, August 2026.Quantum Key Distribution (QKD) provides point‐to‐point, information‐theoretically secure session keys, but distance limitations require trusted relays between remote parties. Can quantum keys be relayed without trusting every intermediate node or depending on a central controller?

Phase watermarking of digital images
Proceedings of 3rd IEEE International Conference on Image Processing, 2002 A watermark is an invisible mark placed on an image that can be detected when the image is compared with the original. This mark is designed to identify both the source of an image as well as its intended recipient. The mark should be tolerant to reasonable quality lossy compression of the image using transform coding or vector quantization.

Journal of Evaluation in Clinical Practice, Volume 32, Issue 5, August 2026.ABSTRACT Background Clinical ethics scholarship on deepfakes has focused primarily on patients as targets of synthetic deception, in which fabricated audiovisual material alters patient beliefs about clinicians and care. This focus neglects the reverse epistemic vulnerability: clinicians themselves as recipients of synthetic, adversarially generated ...
