Implementation of Digital Watermarking For Image Security with EBCOT Algorithm and Error Correcting Codes

In the cutting edge of technology, secured communication media becomes the essential need of multimedia broadcasting. In the reference of multimedia broadcasting, digital audio, video, internet data needs copyright authentication to prevent unauthorized access of data. Digital Watermarking by DWT-DCT with secrete key provides robustness as well as securing information. Digital Watermarking is processed by some way before it reaches to the receiver. The uncompressed digital image has lots of problems related to bandwidth. We can do effective image compression by EBCOT Algorithm. Error correcting codes reduces the effect of noises and attacks on communication channel. Digital watermarking provides cost effective solution for image security and communication.
