A Cloud‐User Protocol Based on Ciphertext Watermarking Technology
Security and Communication Networks, Volume 2017, Issue 1, 2017., 2017 With the growth of cloud computing technology, more and more Cloud Service Providers (CSPs) begin to provide cloud computing service to users and ask for users’ permission of using their data to improve the quality of service (QoS). Since these data are stored in the form of plain text, they bring about users’ worry for the risk of privacy leakage ...

A Guide to Machine Learning Epistemic Ignorance, Hidden Paradoxes, and Other Tensions
WIREs Data Mining and Knowledge Discovery, Volume 15, Issue 3, September 2025.ABSTRACT Machine learning (ML) has rapidly scaled in capacity and complexity, yet blind spots persist beneath its high performance façade. In order to shed more light on this argument, this paper presents a curated catalogue of 175 unconventional concepts, each capturing a paradox, tension, or overlooked risk in modern ML practice.

Information hiding through variance of the parametric orientation underlying a B-rep face
, 2008 Watermarking technologies have been proposed for many different,types of digital media. However, to this date, no viable watermarking techniques have yet emerged for the high value B-rep (i.e.

Geometric Invariant Semi-fragile Image Watermarking Using Real Symmetric Matrix [PDF]
, 2010 In order to improve the detection of malicious tampering of images, it is necessary to decrease the fragility of hidden watermarks, even for digital images which have been distorted incidentally. However, watermarks are sensitive to geometric distortions.

FaceSigns: Semi-fragile Watermarks for Media Authentication
ACM Transactions on Multimedia Computing, Communications, and ApplicationsManipulated media is becoming a prominent threat due to the recent advances in realistic image and video synthesis techniques. There have been several attempts at detecting synthetically tampered media using machine learning classifiers. However, such classifiers do not generalize well to black-box image synthesis techniques and have been ...
