Design and Implementation of Steganography along with secured message services in Mobile Phones is used to provide security to the data that flows across the mobiles. In this paper encryption and steganography algorithms are implemented using JAVA™ with android platform to provide the security for real time multimedia messaging service system. Establishing hidden communication for mobile has become an important subject of security. One of the methods to provide security is steganography. Steganography is used to hide secret information inside some carrier. Hiding information, especially in images has been an alternative solution for secret communication. To improve the security, encrypted secret data will be hidden inside MMS. The image is made to be hidden into image from MMS which provides more secured transmission than text information embedded into the MMS. The Least Significant Bit (LSB) embedding technique is used to hide the secret information (image). Different sizes of secret images are considered and later the calculations have been done for the MSE (Mean Square Error) and PSNR (Peak Signal to Noise Ratio) of image in MATLAB. Encryption and steganography algorithms are ported on HTC Desire mobile device with android version 2.2.3.
