With the advancement of information technology, almost everything in this digital world evolves with information and data. The importance of security and secrecy of data is also increasing enormously. Steganography presents the practice of hiding data or information in any sort of cover medium, e.g image, audio, video. In most of the existing procedures, with the exposure of the keys intruders get successful in picking their required bits. The objective of this paper is to propose and implement a tool for increasing the secrecy of data transmission using steganography. In this paper, firstly we have proposed a technique which adds double layer security to hide data in image using LSB algorithm, AES-128 encryption and a new approach of choosing index of image pixel. Secondly, we have developed a steganography tool using our proposed technique. Finally, we have evaluated the performance of the proposed technique using Mean Square Error (MSE) method, Peak Signal to Noise Ratio (PSNR) and by measuring payload capacity. A comparative analysis of the developed tool with the some existing tools has showed that our tool performs better comparing with some other tools.
