SEMI-FRAGILE AUDIO WATERMARKING ALGORITHM BASED ON HYPER-CHAOS ENCRYPTION
摘要
Abstract
A semi-fragile audio watermarking scheme based on hyper-chaos encryption is proposed.This algorithm has following features:1) eliminates the pertinence of adjacent pixels to watermarking image and truly realises the watermarking image encryption with higher safety by using hyper-chaos sequence to encrypt image watermarks; 2 ) uses mean quantification in watermark embedding, that is to embed the encrypted image line into wavelet packet low frequency coefficients of carrier’s audio section to establish the relationship between them;3) measures the tamper degree in detection process with tampering assessment parameters, and accomplishes the authentication on content integrity of the audio works.Experimental results show, the algorithm has good robustness against conventional operation and accurate localisation on tamper and malicious attacks such as shearing and replacement attacks.关键词
