Image steganography algorithms can be combined with encryption techniques to provide enhanced data security. This papersuggests Least Significant Bit algorithm which is combined with OpenSSL Base64 encryption technique to provide two layer password security. The proposed method uses one of the three colours (RED, GREEN and BLUE) present inside an image pixel to hide data. This algorithm successfully hides the data with the LSB of BLUE colour pixel value present in an image with no remarkable changes in the resulting image.This method is an improved version of Least Significant Bit (LSB) method for hiding information in images.Before applying the Steganography technique,the secret message will be encrypted into cipher text using a random system generated key to ensure password protection.The proposed selective approach results in better data security and reliability.
