Title : External Hardware Security for Steganography
Author Name : Suresh D.S, V. Udayashankara
Synopsis :
Many steganographic techniques are extremely vulnerable to attacks, and even detection of the information in the image file is quite easy. So a microcontroller is used for the sake of security where it transmits a pre-programmed password at the beginning of each process. The steganalysis algorithm continued only if the received password is correct at the destination otherwise retrieving the secure information from the cover image is impossible.
