Robust signal hashing defines a feature vector that characterizes the signal, independently
of" nonsignificant" distortions of its content. When dealing with images, the considered …

The goal of video hashing is to design hash functions that summarize videos by short
fingerprints or hashes. While traditional applications of video hashing lie in database …

In this paper, we propose a nonlinear structural hashing approach to learn compact binary
codes for scalable video search. Unlike most existing video hashing methods which …

Perceptual hashing has been broadly used in the literature to identify similar contents for
video copy detection. It has also been adopted to detect malicious manipulations for video …

Robustness and discrimination are two of the most important objectives in image hashing.
We incorporate ring partition and invariant vector distance to image hashing algorithm for …

Recently, learning based hashing methods have become popular for indexing large-scale
media data. Hashing methods map high-dimensional features to compact binary codes that …

This paper present the concept of robust video hashing as a tool for video identification. We
present considerations and a technique for (i) extracting essential perceptual features from a …

Image hashing is an emerging technology in multimedia security for applications such as
image authentication, digital watermarking, and image copy detection. In this paper, we …

Hashing method is an efficient technique of multimedia security for content protection. It
maps an image into a content-based compact code for denoting the image itself. While most …

Due to large volume and high variability of editing tools, protecting multimedia contents, and
ensuring their privacy and authenticity has become an increasingly important issue in cyber …
