Image Watermarking Technique Based on Two-Dimensional Chaotic Stream Encryption

Abstract

This paper proposes a kind of wavelet domain image digital watermarking technique using two-dimensional chaotic stream encryption and human visual model. A stream encryption algorithm based on two-dimensional Logistic chaotic map is researched and realized for meaningful grayscale watermarking image. The block embedding intensity is calculated and combined… (More)
