WebThe LSB steganography method is also implemented to store key information securely. The file is divided into three parts during the encryption process. Each part of the file will be encrypted using a dissimilar encryption algorithm simultaneously. After the encryption process, the key information is inserted into an image using the LSB method. WebCryptography is used to cipher information and steganography is used to hide the reality of data communication. Cryptography scrambles the information by using a key so that a third party cannot access the information without the key.Cryptography is also called as the science of secret script.
