Research that began a decade ago in video copy detection has developed into a technology
known as" video fingerprinting". Today, video fingerprinting is an essential and enabling tool …

In the recent digitization era, image hashing is a key technology, including image
recognition, authentication and manipulation detection, among many multimedia security …

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 …

This paper designs an efficient image hashing with a ring partition and a nonnegative matrix
factorization (NMF), which has both the rotation robustness and good discriminative …

A video copy detection system that is based on content fingerprinting and can be used for
video indexing and copyright applications is proposed. The system relies on a fingerprint …

Video fingerprints are feature vectors that uniquely characterize one video clip from another.
The goal of video fingerprinting is to identify a given video query in a database (DB) by …

In this paper, we propose a robust image hashing scheme based on perceptual texture and
structure features. Through pre-processing, the input image with arbitrary size is regularized …

In this paper, a novel perceptual hashing scheme for color images is proposed with the
hybrid feature extraction mechanism. During the stage of pre-processing, image …

Public concerns on image encryption grow significantly as the development and application
of edge computing and the Internet of Things intensified recently. However, most existing …

An image hash should be (1) robust to allowable operations and (2) sensitive to illegal
manipulations and distinct queries. Some applications also require the hash to be able to …
