Steganography is the art of hiding secret information into the cover image. Steganography can be combined with cryptography to achieve a higher level of security. Recent techniques in steganography, focuses on higher embedding capacity and lower distortion. In phase- 1 of the project work, a steganography technique using Discrete Wavelet Transform (DWT) was proposed which achieved a higher embedding capacity for the secret data.
