Abstract(in English)	In this paper an image authentication algorithm is proposed where the modified areas in an image are detected, in addition an approximation of the original image, called digest image C_, is recovered. Two different watermarks are used. One semi-fragile watermark wi is used for authentication phase. The other, digest image C_ is compressed using an arithmetic code, then redundancy is added by applying BCH error correcting code (ECC) resulting W_. Finally, both watermarks are embedded in the integer wavelet transform (IWT) domain. The proposed scheme is evaluated from different points of view: watermark imperceptibly, payload, accuracy detection of tamper area and robustness against intentional attacks. Experimental results show the system detects accurately where the image has been modified and the recovered digest image has a good quality.
