Abstract :
A simple technique based on integer discrete Hartley transform (DHT) is presented for embedding data of various different forms in digital images. Not only it involves significantly less computational complexity, but also accommodates considerably more payload and offers better visual quality over the existing schemes. Due to the lossless reversal behaviour of the integer DHT, the proposed technique can also be used for lossless retrieval of the embedded data as well as the host image from the embedded image
