Image authentication is important in content delivery to preserve originality as well as integrity of data.Using handwritten signature we can authenticate a person accurately.This paper proposes an efficient image authentication technique by hiding handwritten signature image in selected DWT sub-band of the image.At the receiver end signature image is extracted and verified with template signature using Artificial Neural Network and hence image authentication is achieved.
