AB  - This study has suggested a semi fragile watermarking technique for proving the authenticity of image.
The suggested technique is also used for detecting any tampering may be done on the image. The suggested
technique has extracted the feature distribution (digital signature) image from the cover image to be as a
watermark. The digital signature image represents the important edges which are extracted from the coefficients
of a Discrete Wavelet Transform (DWT). Later, the created signature (watermark) is embedded in the cover
itself. The suggested scheme could decide whether the image is tampered or not in addition to localize the
tampered region. After applying the suggested technique, the results had shown that it could detect and
localize detect and localize any tampered region in image. In addition, the suggested technique could decide
whether the tampered region is attacked intentionally or unintentionally.
