Abstract
Today, security of data transmission is a big problem in society. Information security fields play a vital role in network communication. To secure information, cryptography and steganography are widely used. Image steganography become popular because images are frequently used on internet. In this paper, the combination of cryptography and steganography is used to provide more secure which mean that it provides two layers protection. The secret audios or important speeches are recorded and this secret data is encrypted using Advance Encryption Standard (AES). This cipher data is embedded into cover images using Random-Based Least Significant Bit method. The random positions of image for LSB are also generated by the use of AES key. The resulting stego images are sent to the receiver and the receiver needed to perform the reverse processes to obtain the secret data. The image quality is analyzed in terms of both Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) measured between the cover image and stego image.
