Internet is one of the medium of communication mostly used now a day. To conserve the security of information sent over the internet, steganographic concept makes its arrival. Least-significant bit and multi-bit embedding methods are the most well-known and familiar in this domain. Here, in this work, only least-significant bit method is used. It is a new technique which is indeed very simple in comparison to the other existing ones in the sense that secret information is hidden inside the image. Here, we obtain an embedding ratio almost 8 times of the existing LSB algorithm by combining steganalysis tool ‘bit-plane’ and LSB algorithm applied over Gray-scale image. Estimated variance and standard deviation of stego-image is reduced here by deploying ‘complement approach’, LSB algorithm and bit-plane, which thereby enhances the quality of stego image. Hence, it is not possible for the intruder to extract content of the message sent by the user without using statistical approach (e.g.: correlation, standard deviation etc.). If somehow intruder manages to extract the content then he/she have to use sterilization techniques to destroy the information.
