Abstract :Nowadays, data security has become very important. A data can be hidden with a steganography technique into text, image, audio and video files. Steganography is used widely data security applications. But there are stegoanalysis methods that provides obtaining hidden data. To prevent this, steganography can be used with cryptography or different methods. Cryptography is not enough alone for data security sometimes. In this study, the information is encrypted and hidden because of it is important to prevent capture of information by undesirable persons. Firstly, plain text is encrypted with RSA encryption algorithm and then encrypted data is hidden into an image for data security in this study. Stego image consist of text and an image which is data hidden into an image. We show that how is hidden information and besides how visual difference is become on example images.
