FPGA implementation of an efficient 2D 5/3 Lift DWT based invisible watermarking technique

Nowadays the use of internet is rapidly increasing. The advancement in the technology has lead to the increase in the speed of transmitted data over the network. There is a chance of copyright of individual´s creation where the information is vulnerable to the unauthorised parties. So we need to preserve individual´s creation from the copyright. Hence there is a need in digital watermarking technique. The main aim of the project is to investigate the effect of peak signal to noise ratio (PSNR) values for digital images using 5/3 2D Lift DWT based watermarking technique. The proposed system is designed with an efficient secured algorithm for enhancing the visual quality. The results show that the secret data/watermark data can be hidden by making it invisible. Hence invisible watermarking technique can be used to secure the data and helps to preserve individual´s creation from copyright.
