An effective fragile watermarking scheme for color image tampering detection and self-recovery

作者：

Highlights：

• High quality of the watermarked image in comparison with other schemes was confirmed.

• Novel tampering detection algorithm in each RGB channel has been designed using three tamper results.

• Better robustness against the tampering coincidence problem is obtained.

• Better manipulation detection was achieved during authentication.
