Biometric watermarking for medical images – example of iris code

Wioletta Wójtowicz


This paper presents a preliminary investigation on medical image watermarking using biometric watermarks. The goal is to elaborate simple watermarking system based on discrete wavelet transform (DWT) decomposition and binary iris code insertion. The performance of proposed algorithm is evaluated by Hamming distance between embedded and extracted iris code.
