Digtal Watermarking Based on the Error Correcting Coding

Abstract

Abstract.A novel digital watermarking scheme is proposed instead of the traditional watermarking. The binary watermark image is processed by error-correcting coding before it is embedded into the discrete wavelet-transformed host image. It is more effective to improve the security and robustness of the watermarked image by proposed scheme. Amount tests and results indicate that the proposed scheme have security and robustness against noise and commonly image processing methods such as Gaussian's noise, filtering, JPEG compression, and crop procession etc.
