The proliferation of digital images creates problems for managing large image databases, indexing individual im- ages, and protecting intellectual property. This paper in- troduces a novel image indexing technique that may be called an image hash function. The algorithm uses ran- domized signal processing strategies for a non-reversible compression of images into random binary strings, and is shown to be robust against image changes due to compres- sion, geometric distortions, and other attacks. This algorithm brings to images a direct analog of Mes- sage Authentication Codes (MACs) from cryptography, in which a main goal is to make hash values on a set of dis- tinct inputs pairwise independent. This minimizes the prob- ability that two hash values collide, even when inputs are generated by an adversary. |
