Steganography is the technique used to hide the information within a medium (image, audio, and video). This technique has been applied using different approaches (algorithm) such as Least Significant Bit algorithm, spatial algorithm, XOR algorithm, etc. All the algorithms have pros and cons when compared with each other. In order to give a highly efficient, secured and optimum algorithm, the combined LSB and XOR algorithm has been developed. This algorithm uses two algorithms i.e. Least Significant Bit (LSB) and Exclusive OR (XOR). Initially, the pixel values of an image (which is going to encrypt the message) and the message is been found, then all the 2nd LSB of the image is XORed with pixel value of the message and replaced with the LSB of the image. After the completion of above approach, information is sent to the particular end-user. The end-user for decryption has to take the 2nd LSB values of the encrypted image and XOR it with the LSB of the encrypted image. This approach is more efficient, secured and easy to use and understand.
