Abstract |
|
Steganography is used to carry information from source to destination using public channel in such a way that only sender and intended receiver know that there is hidden message. This paper represents image steganography method that is based on LSB and DCT coefficients that provide randomized bits embedding inside the cover image. Firstly the Discrete Cosine Transform (DCT) apply on the cover image and then hiding the secret information in LSB of the cover image in random locations based on threshold value. Using DCT Coefficients value, Find the randomized pixel locations for hiding secret information and increase the security of system. |
