A Secure and Robust Image Hashing Scheme Using Gaussian Pyramids
Entropy, 2019 Image hash is an alternative to cryptographic hash functions for checking integrity of digital images. Compared to cryptographic hash functions, an image hash or a Perceptual Hash Function (PHF) is resilient to content preserving distortions and ...

Hashing into quadratic residues modulo a safe prime composite [PDF]
, 2023 For $n = pq$ a product of two safe primes, we construct and prove security of a cryptographic hash function $H$ mapping into the square residues $QR_n \subset (\mathbb{Z}/n\mathbb{Z})^*$, by squaring the output of an ordinary cryptographic hash function $

Collision-resistant hash function based on composition of functions [PDF]
, 2011 cryptographic hash function is a deterministic procedure that compresses an arbitrary block of numerical data and returns a fixed-size bit string. There exist many hash functions: MD5, HAVAL, SHA, ...
