Abstract: During data transfer, stealing of data by unauthorized parties is common now days. Various techniques are available to provide security to data; from which proposed system uses LSB and pseudo random encoding technique. Steganography means covered writing. The main goal of this technique is to hide existence of message from unauthorized parties by hiding it into image. The quality of proposed system is compared using various parameters like MSE, RMSE, PSNR and Capacity based on different sets of images. Our proposed system attains a PSNR of 49.32 and 94% Accuracy.
used with communication protocols. Digital image steganography is method of secret communication that aims at hiding large number of secret data based on size of cover image. The main goal of stegano system is to embed secret message in cover image by choosing a random stegano key. The stegano file is created that represent the cover file with embedded message that is indistinguishable neither by human nor by computer system. An encoded message is send to receiver side along with stegano key where it is decoded to get the credential information.
Keywords: Steganography, LSB, Random-key, Stegano-Key.
2. Methods of Classification The steganographic system is classified based on the type of cover image it use or on the method of hiding or on the basis of layout of modification used in embedding process.
1. INTRODUCTION Digital steganography is the art and science of hiding communication. A steganography system embeds a secret data in cover media to hide its existence from unauthorized parties. A steganography system has two main aspects: steganographic capacity and imperceptibility. These two characteristics are odd to each other. It is difficult to increase the steganographic capacity simultaneous with imperceptibility. There are few methods of steganography to be Š 2017, IRJET

2.1 Cover-Type Based Classification There are various kind of digital media used as cover file of steganography. The properties of cover file vary from one cover file to another. The properties of these files control how the secret message can be hidden in these files. The type of cover file give us an idea that where secret message might be hidden. The different |
