Digital Image Watermarking Techniques of Spatial and Frequency Domain Hybrid Platform

-In the today’s high scale communication of data there is a pressing need is generated for protection of the data information from many of the illegal duplication and modifications. For this purpose image watermarking is getting a very growing focus for a solution to the theft and tampering by involving the applications of advanced digital image processing operations to watermark copyright and authentication information inside the image content. Presently we are giving implementation results for a spatial and frequency domain hybrid platform watermarking techniques that are involved in designing a secure image data transmission. We have focussed on both spatial and frequency domain aspects in image watermarking and proposed various hybrid scheme which have currently proving themselves as more robust and almost invariant to some of the image attacks.
