Abstract :
This paper evaluates Ouda and El-Sakka scheme (OE for short) which is a tamper-localization watermarking. OE is a public block-wise scheme which enables everyone to identify the tampered regions. However, we point out OE scheme may identify a forge blocked to be intact, and accuse an intact block to be corrupted.
