In Steganography there are many techniques which are used to hide the data in different formats. Most general one is the least significant bit (LSB) substitution method, which is commonly used due to its simplicity. It provides protection to data by hiding it in digital image. But simple use of this approach is more vulnerable to attack. In this paper we have discussed the art and science of Steganography in general and proposed an algorithm which is the variant of LSB substitution method. It efficiently and effectively hides data with the help of a key in JPEG colored digital image. Security of hidden data is proportional to the length of key used. Proposed algorithm is capable to hide more data in cover image and require no pre processing. Results show that there is less detectable distortion in the stego image and opens the track for proposed algorithm to be used in data hiding and secure transmission.

Steganography refers to the branch of computer science which deals with the covering up message in the format which cannot be detectable by any intruder. The secret message or the confidential data can be sent over internet with security using various steganography techniques. This technique has overcome many drawbacks of traditional method of cryptography in which data is encoded and sent over the internet which can be seen by the intruders and they can make attack on it. It is possible for the intruder to make the intrusion sometimes when the cryptographic algorithm is not sufficient enough but in case of steganography no one knows except the receiver that the message sent is confidential or hidden in some kind of picture, audio or video. So it makes it lot secure to send the message over internet with the use of steganography. In the proposed paper the detail information of image steganography is presented along with the applications and methods used for this process.
