Lecturers from the Department of Computer Science are spreading a research of protection of copyright for pictures mobile service

Lecturers from the Department of Computer Science at the University of Technology Dr. Israa Abdel Amir Abdul-Jabbar, dr. Suhad Mal Allah Kadhem published a search of protection of copyright for pictures mobile service
Copyright Protection Service for Mobile Images
Eng in the magazine. & Tech.Journal, Vol.34, Part (B), No.4,20
The research aims to provide a protocol to add and retrieve digital watermark images as an institution for the protection of copyright, which works to record any pictures of any task a user needs to provide privacy for documents private.
Registration is done by the server works to record images for only once while retaining On add watermark supported the process safe authorize incorporate both encryption and digital signatures, which serve as the watermark invisible image will appear only visible in the bottom / right side watermark from the customer image.
The proposed protocol consists of three phases is generating watermark and concealment and recovery. While it composed the process of generating the key from three steps: the first step is encrypted mobile number with the global icon using the SHA-1, and in the second step is encrypted step output of the first with the watermark text in a manner SHA-1 again, and the third step is the result of encrypting The second step RSA algorithm.
For the second phase of the protocol conversion algorithm wavelet intermittent used to hide the watermark in the image and for the last stage of the image is matched with the recovered watermark decoding recovered watermark blade of the mobile number. As a result, both the concepts of complementarity and authorization were able to get them from the proposed protocol because the encryption method SHA-1 is still safe to the present time. This system and achieve mutually authenticity Cover and safe transport of high Petkamlah High and authorization
