The exponential growth of digital data in cloud storage systems is a critical issue presently
as a large amount of duplicate data in the storage systems exerts an extra load on it …

Perceptual hashing is used for multimedia content identification and authentication through
perception digests based on the understanding of multimedia content. This paper presents a …

In this paper, a novel perceptual image hashing scheme based on convolutional neural
network (CNN) with multiple constraints is proposed, in which our deep hashing network …

To authenticate an image using a hash function is a challenging task since several core
issues like tamper detection, security and robustness needs to be addressed. In this paper …

Perceptual image hash has been widely investigated in an attempt to solve the problems of
image content authentication and content-based image retrieval. In this paper, we combine …

For detecting the image copies of a given original image generated by arbitrary rotation, the
existing image copy detection methods can not simultaneously achieve desirable …

Image authentication has become an emergency issue in the digital world as it can be easily
tampered with the image editing techniques. In this paper, a novel robust hashing method …

In this paper, we propose a novel perceptual image hashing scheme based on block
truncation coding (BTC). In the proposed scheme, the pre-processing is first applied on …

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 …

In this paper, we propose a robust image hash algorithm by using the invariance of the
image histogram shape to geometric deformations. Robustness and uniqueness of the …
