Confidentiality of Data Through Steganography

Abstract

Now-a-days providing security & making data to be confidential plays a major role. For the purpose of providing confidentiality we are employing the cryptography techniques. Even though the data get encrypted, the intruder easily modifies the data by knowing the presence of confidential data. Steganography, which can called as an extension to the cryptography. Hereby employing this technique, can remain the existence of information in confidential. For providing security an image is used as a carrier medium to hold the secret data. Thereby no one can have an idea there is a secret message with in an image. The LSB technique of steganography is going to be applied here and secret key is generated by using one of cryptography technique OTP. With this method we can hide the data efficiently and effectively.
