What are three data hiding techniques?
Abstract: Data transmission needs security. Data hiding can be achieved through many methods. Different data hiding techniques are discussed in this paper which includes watermarking, steganography, fingerprinting, cryptography and digital signature.
What is data hiding in digital forensics?
