Wavelet-Based Blind Watermarking Technique for Real-Time Watermark Interpretation
The Digital watermarking algorithm is embedding watermark into digital content without degradation of original image. The watermark should be robust against attacks to the copyrighted content. Also, extracted watermark can be able to identify the image ownership without ambiguity. In real-time watermarking system, watermark extract algorithm must be distinguishing the imitations from the originals on the instant. In this paper, the proposed watermarking algorithm shows unambiguity and security using pseudo-random linear congruention generators and binary code to decimal with student ID number. The experimental results show that the proposed algorithm successfully survives several kinds of image processing operations including JPEG lossy compression.
