Along with advances in information technology, cyber-crime techniques also increased. There are several forms of attacks on data and information, such as hackers, crackers,Trojans, etc. The Symantec Intelligence report edition on August 2012 indicated that the attacker selected the target of attacks. The type of data is valuable and confidential. The Hackers selected the target to attack or steal interest information the first and they did not just taking random from a large amount of data. This indication worried because hackers stealing the data more planned. Therefore, today many systems reinforced with various efforts to maintain data security and overcome these attacks. Necessary methods to secure electronic messages that do not fall on those who are not authorized. One alternative is steganography. Cryptography and Steganography are the two major techniques for secret communication. Cryptography converts information from its original form (plain-text) into unreadable form (cipher text); where as in steganography is the art of hiding messages within other data without changing the
data to it attaches, so data before and after the process of hiding almost look like the same.

There are many different techniques are available for cryptography and steganography. The cryptography suspicion against disguised message is easily recognizable, because of the message disguised by changing the original message becomes as if illegible. While further reduce suspicion steganography disguised as a message hidden in the file.

The project designed the application of steganography using Least Significant Bit (LSB) in which the previous message is encrypted using the Advanced Encryption Standard algorithm
(AES) and it can restore the previously hidden data. The messages in this form application and hidden text on media digital video so as not to arouse suspicion. The result of research shown the steganography is expected to hide the secret message, so the message is not easy to know other people who are not eligible.

Implementation Section

Encryption Part
1) Initially Cover Video is given as input in which data is to be hidden.
2) A text file or text data (Secret data) is provided which is to be hidden.
3) Above Secret data is initially encrypted using AES Encryption with provided encryption key.
4) The encrypted data is then hidden into cover video using LSB based Steganography.

Decryption Part
1) Cover Video with hidden data is given as input.
2) Secret data is fetched from the cover video using reverse LSB Steganography.
3) AES Decryption is applied to the secret data and plain data is generated as output.
