The world in current days is by and large increasingly more attached to the utilization of innovation for encouraging everyday undertakings. In such manner, data security is going to be extraordinary test when sending data starting with one spot then onto the next with the guide of innovation. Steganography is one of the systems for the sheltered transmission which includes concealing data for the most part with other data that lone the beneficiary will know. In this exploration, steganography system utilizing Discrete Cosine Transform (DCT) is executed. First the spread picture is changed utilizing DCT and mystery data is inserted in coefficients of DWT which gives stego picture. Switch procedure is connected to acquire mystery data from stego picture. The presentation of the proposed methodology is assessed utilizing PSNR and MSE.
