A Watermark Algorithm Against De-Synchronization Attacks
A Watermark Algorithm Against De-Synchronization Attacks
In this paper, a robust method to the ability of the watermark to resist against attacks is proposed for hiding information into images. The proposed method is blind because the original image is not required at the decoder to recover the embedded data. The robustness of the watermarking scheme is inspired by using a PJND (Pyramidal Just Noticeable Difference) model and the message is inserted into these DoG.
