Given the rapid expansion of the Internet of Things and because of the concerns around
counterfeited goods, secure and resilient cryptographic systems are in high demand. Due to …

The perceptual video hash function defines a feature vector that characterizes a video
depending on its perceptual contents. This function must be robust to the content preserving …

A perceptual video hash function extracts a short fixed-length bit string called a perceptual
hash on the basis of the visual contents of the video. Such a function should be robust to the …

A function that outputs a feature vector from the perceptual contents of the input video is
called a perceptual video hashing function and the output feature vector that characterizes …

In this paper we propose a spatio-temporal digital video hashing scheme. In the proposed
scheme, the digital video is treated as a three dimensional signal. Edge Orientation …
