Scalable fragile watermarking for image authentication

IET Information Security, 2013
Semi‐fragile watermarks are used to detect unauthorised changes to an image, whereas tolerating allowed changes such as compression. Most semi‐fragile algorithms that tolerate compression assume that because compression only removes the less visually significant data from an image, tampering with any data that would normally be removed by compression ...

Filtering Trust: Disclosing the Role of Artificial Intelligence Decreases Trust in Technology, but Does Not Prevent Harm to Body Image After Viewing AI‐Generated Content

International Journal of Eating Disorders, Volume 59, Issue 6, Page 1304-1312, June 2026.
ABSTRACT Objectives Despite the rapid growth of generative artificial intelligence (AI), virtually no research exists examining the psychological impacts of viewing or interacting with AI‐generated images of people. Additionally, it remains relatively unknown whether informing viewers when images are AI‐generated is an effective way to lessen harm or ...
