A Multi-purpose Video Watermarking Algorithm Based on Wavelet Transform and Image Partition
Currently, robust, invisible double digital watermarking technology becomes the most popular and challenging direction, it has aroused great concern in the international community in recent years. The single watermark algorithms always merely have single function. In order to overcome the drawbacks, a multi-purpose dual watermark algorithm based on wavelet transform and image partition is presented in the paper. The algorithm embeds both robust watermark and fragile watermark to one video sequence by using DWT and multiple embedded methods. The later embedded fragile watermark is served for the early robust watermark. The experiment results show the proposed algorithm is more robust and imperceptible, and it can achieve copyright protection and content authentication at the same time.
