Robust Perceptual Hashing Based Identification A Vs Authentication 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, we propose a hash based image authentication scheme that simultaneously attempts to address these core issues. For a better understanding and design of a robust image hashing algorithm, it is very crucial to look into few important parameters like discrimination, robustness, reliability, etc. this paper reflects a detailed study of the existing literature on hashing based image authen tication techniques.

Abstract: in recent decades, a large number of robust image hashing methods have been designed for image authentication. however, existing hashing methods generate hash sequences from the plaintext images. Existing designs of image content authentication from advanced cryptographic primitives achieve robustness, security and versatility, at the cost of low efficiency. in this paper, we present a new design of image authentication with an improved trade off among the aforementioned features. This paper introduces a robust image hashing technique based on the discrete wavelet transform (dwt), designed to enhance security in image authentication. Firstly, a landscape lighting model was constructed based on color constancy theories, and the quality of landscape images was improved with color constant image enhancement technology.
