The rapid growth in the transmission of information through the internet has given attention on information security for decades. Digital data like text, image, audio and video in the digital form are the major components being transmitted over the internet. In everyday life, images like diagrams, paintings, digital arts constitute the major part of multimedia content. This paper consists of a model for intellectual property protection system that is a combination of Modified Least Significant Bit embedding (MLSB) and Enhanced Modified Rivet Cipher 6 (EMRC6) for encryption. The input data is either text or two dimensional image but this model can be extended to video data too. The MLSB embedding scheme is a static watermarking method which is an improvement of the basic Least Significant Method (LSB) and is suitable for authentication purpose. The EMRC6 encryption scheme is a block cipher which is faster and secure than its predecessors. Since a static watermarking scheme and a block encryption schemes are integrated together, this model provides a high level of security and increases the payload. The output digital image has good visual clarity, since the PSNR value is around 44 dB on an average and the correlation coefficient is near to zero. The encryption time is very low and the throughput is high thus concluding that the working model is very fast.
