Modified LSB2 Steganography Method to Secure the Embedded Secret Message

LSB2 method of data steganography is a popular method of secret data hiding, this method is simple and capable of hiding long messages in a covering color image. LSB2 is not secure and it cannot protect the embedded secret message from being hacked. In this research paper a modified LSB2 method will be proposed, this method will solve the security issues by using a secret private key. This key will contain 8 components and will be used to rearrange the sequence of bits hiding in the covering image. The proposed method will deal with the hiding process by selecting the first bits of the message characters, the seconds and so on. An extra task will be added to LSB2 method; this task will perform the necessary substitution of the message binary matrix according to the contents pf the PK. The PK key be easily changed when the need arises without modifying the proposed algorithm. The proposed method will be implemented using various messages and various covering images. The obtained results will be analyzed using various types of data analysis to prove the efficiency of data steganography. A quality analysis will be performed to prove the quality of the stego image, and speed analysis will be performed to prove the optimized throughputs provided by the proposed method.
