Selective Region based Invisible Water Marking using Asymmetric Key Encryption

This introduces an approach, to deal with invisible water marking, by interactively selecting the appropriate threshold values each time to choose the desired area to embed the watermark, the informative image and encrypting the complete embedded image using a well-known asymmetric key cryptographic algorithm, RSA, with a static encryption table generated by choosing two large enough prime numbers, that satisfy the need required for this purpose.
