Abstract
The spreading of internet has enabled basically anybody to send and receive information from anywhere in the world . With this increase in exchange information over the internet comes the risk of experiencing a breach in security through exposing users sensitive data to unauthorized and potentially malicious individuals . This risk can be overcome through make data unreadable by unauthorized persons ans also through hide our confidential data in another data in order to make unauthorized persons unaware for the fact of the data transferred. Different techniques of data security have been proposed cryptography and steganography are two main methods.
