Watermarking for JPEG image using error correction coding

Compression is the most common process that limits the robustness of watermarking. We propose a watermarking method for JPEG compressed color images in the semi-decompression domain, using Reed-Solomon (RS) codes. The watermark embedding and recovery processes can be applied without decompressing the compressed file completely. There is no perceptible degradation between the watermarked image and the original image. Experimental results show that the scheme is robust against some distortion attacks and JPEG lossy compression with different compression rates
