Comparative Analysis for Steganographic LSB Variants

Combining the best features of steganography and cryptography is the trending concept which is being followed for the purpose of information security. Hence, this combination is making the data more powerful and secure against the prevailing security attacks and breaches. This paper represents the implementation of this combination on the two LSB variants, namely sequential LSB and randomized LSB. A comparison among the two approaches is carried out by adding a secret text into a video cover file. The concept of chaotic sequence has been used as the security approach that converts the secret data into random bits pattern. The proposed work uses the traditional LSB approach as basic steganographic model. The inference on the basis of parameters concludes that the randomized LSB shows better results than the sequential LSB scheme.
