<u>Explanation:</u>
Steganography is a technique used in securing or hiding sensitive information by encrypting the information in a non-hidden file like a JPEG format. A major <u>advantage</u> of this method is that it reduces the risk of attack or break-in since the data is enclosed in a non-secure file; thereby reducing threats of any hack. One main<u> disadvantage</u> of this method is that the hidden message may become difficult to recover if the source file (non-secure file) used, is edited or deleted.
In symmetric or asymmetric encryption they both employ cryptographic encryption method. While symmetric encryption uses one key to encrypt and decrypt data, asymmetric encryption uses two keys (one for encryption, the other for decryption) of the data. <u>A major </u><u>advantage</u><u> of using these methods is that they provide more security. Although while symmetric encryption is faster, asymmetric encryption is slower (eg using separate keys to gain access), </u><u>a disadvantage.</u>
