A hybrid intelligent security technique used for digital still image

Digital communication & internet technology has brought big revolution in transferring of digital data in 21 st century. Android operating system has enhanced all application of digital technology. Digital data can be transfer in various format like image, text, animation, graphics, message, video, audio, etc. For transferring the digital data like image, there is need of various multimedia models which can support digital image property. Such as image types, seeing colors containing different color model, human vision, interaction of light with matter, image resolution & bit depth. To maintain all these property of single digital still image of scanned cheque document, there is requirement of security, privacy & authentication. This can be done by using techniques like digital image watermarking and its combination with encryption & decryption techniques. In this research paper, a hybrid intelligent DWT-SVD digital image watermarking technique is used for authenticity & ownership whereas advanced encryption standard technique using 256 bit key is used for security of digital cheque image.
