In this pervasive world, we can access anything from anywhere. To have a secret communication, we need a technology such that no one is able to read or modify the secret message. The message should be sent without any intrusion by eavesdroppers. The secret message could be encrypted using cryptography and communicated. But a third party might suspect the presence of the secret message in this case. So, in order to hide the presence of the secret message, steganography is employed. Human eyes are imperceptible to the LSB changes in images and thus messages could be hidden in them. Image steganography will be powerful if there is not a proper sequence in the changes done to the pixels. In this proposed methodology, the secret logo is embedded in an image resulting in the stego-image 1. This is embedded in one more image resulting in stego image 2 which is again embedded in one more image to achieve 3rd level security. To get the secret logo we need to do the same process in the reverse manner. MSE and PSNR are calculated for the proposed method all levels.
