Abstract The image is the important object of media propagation on the internet. The problem of ownership copyright authentication
and content integrity of the image on the internet need to be solved urgently. In order to solve this problem, this paper presents
a watermarking algorithm combined with Logistic chaotic mapping and IWT. Improve the safety performance of the watermarking
algorithm with using Logistic chaotic mapping both in the process of watermark encryption and watermark embedding.
