An Improvement on the Security of Odd-Even-LSB Based Steganography by Adding Encryption

Information can be hide by various methods. Steganography is one of the most common techniques using for hiding secret message inside the cover objects by using Least Significant Bit (LSB). Basically, the secret data refers to a message which is saved as a text file that needs to be hidden. The paper purposed an image based steganography that odd-even Least Significant Bits techniques and cryptography technique will use for enhance the security of simple odd-even LSB which has been introduced by Nain. N et al. (2012). This paper aims to increase the security of odd-even-LSB based steganography by adding encryption algorithm on text message before embedding. The purposed algorithm tested by PSNR and the results shows that the improved algorithm is 2.5 percent more secure than the previous algorithm. Although the algorithm was attacked by cropping, resizing, jpeg compression and adding noise and the result examined.
