Perceptual Hashing-Based Robust Image Authentication Scheme for Wireless Multimedia Sensor Networks
International Journal of Distributed Sensor Networks, 2013 Image authentication is critical for secure image transmission and storage in a wireless multimedia sensor network (WMSN). In this paper, we propose a perceptual hashing-based robust image authentication scheme, which applies the distributed processing ...

Two-Phase Method for Image Authentication and Enhanced Decoding
IEEE Access, 2017 A two-phase method for image authentication using side information from the communication channel, followed by improved error correction using reliable data, is presented. The functionality of the proposed method is divided into two phases.

A Survey on Image Hashing for Image Authentication
IEICE Transactions on Information and Systems, 2010 The traditional cryptographic hash functions are sensitive to even one-bit difference of the input message. While multimedia data always undergo compression or other signal processing operations, which lead to the unsuitability of multimedia authentication using cryptographic hash. The image hashing has emerged recently which captures visual essentials

Lossless image authentication algorithm based on adaptive combinations of image basic blocks
Tongxin xuebao, 2012 As the existing block-wise lossless image authentication algorithms were inadequate in the division of image authentication blocks,a novel lossless image authentication algorithm based on adaptive combinations of image basic blocks was proposed.The image

Secure Image-Authentication Schemes With Hidden Double Random-Phase Encoding
IEEE Access, 2018 We present a new image-authentication algorithm based on binary-quantified double random-phase encoding (DRPE) and a discrete cosine transformation (DCT) domain watermarking scheme. The image is encrypted using a DRPE scheme, in which only the phase part

Image Authentication By Statistical Analysis
, 2013 This paper investigates the discrimination between Photographic Images (PIM) and Computer Generated (CG) images. The proposed method exploits traces of Color Filter Array (CFA) interpolation, present in PIM images, together with the use of hypothesis testing theory.

A Novel (2, 3) Reversible Secret Image Sharing Based on Fractal Matrix
IEEE Access, 2020 This article first proposes two types of three-dimensional (3D) fractal reference matrices. Then, a new reversible (2, 3) secret image sharing scheme based on a fractal matrix is presented.
