Paper Title
Using Digital Wavelet Transform With Colored Images to Host Secret Signatures For Ensuring The Integrity of Content
Abstract
Handwritten signatures were used over hundreds of years to prove the identity of certain person. Moreover,
handwritten signatures were used to prove the content integrity of certain document. This work gives a new procedure of
hiding digital signature in digital colored images that solves the challenge of identity and integrity. The proposed procedure
depends on changing the digital colored image from spatial domain to discrete wavelet transform domain and hiding the
digital signature secretly in the transformed image. Then, the resultant image is retransformed to the spatial domain. The
human visual system cannot differentiate between the original image and the image that carrying the secrete signature. The
used procedure gives the signature strength and stiffness sufficient to overcome different types of attacks.
Keywords- Digital Signature, Identity, Content Integrity, Digital Wavelet Transform, Watermarking.
