Abstract
The advancing world of digital multimedia communication is faces problems related to security and authenticity of digital data. In the context of multimedia communication, digital images and videos have numerous applications in entertainment world like TV channel broadcasting. Digital Watermarking algorithms used to protect the copyright of digital images and to verify multimedia data security. Most watermarking algorithms transform the host image and embedding of the watermark information by robust way. Uncompressed digital images need a lot storage capacity and bandwidth so efficient image transmission need image compression. The solution is becoming more complex with the growth of data. We propose Digital Watermarking by proposed transform Algorithm based on DCT-DWT watermarking. By this method we can do secure image transmission.
