77 Multiresolution and Quantization-Based Digital Watermarking Technique for Multimedia Content Protection
Download citation file:
The traditional approach to data protection is to apply encryption and scrambling. These methods alone are not adequate to provide complete content-protection since they cannot protect the data once it has been decrypted and descrambled. A recent technique called digital watermarking is proposed as a complementary approach to data encryption. Digital watermarking is a process in which security or authentication data is imperceptibly embedded within a host data. In this paper, we propose a robust blind image watermarking algorithm for embedding a binary watermark sequence under the wavelet domain. Using a quantization-based modulation technique to embed the watermark, this method...
