Information security is a huge trending topic in recent year. Many technique and algorithm were designed and developed toachieve the security of information and/or network across the world. Cryptography is one of the most common tools to provide suchsecurity. Nevertheless, steganography also provide a good security by hiding data within a media in a way that an attacker can't sensethe presence of the secret data. Compression don't normally imply any security , however , it messes up the original encoding of the dataand reduces its size by a measureable amount which makes it perfect for hiding .In this paper a system was proposed where a secretimage is compressed before encryption and hiding. JPEG algorithm was used for the compressing, while at the encryption stage RC4algorithm was used due to its fast processing speed. LSB (Least Significant Bit) technique then applied to hide the secret data within thecover image.
