Hiding Data into an Image by Using Cryptography and Steganography
Coşkun Balkesen, Hasan Erdinç Koçer · 2019
Today, with the widespread use of communication technologies, the need for securing the information has increased. This study has been conducted to contribute to the security of information by taking advantage of two important areas of security, such as cryptography and steganography techniques. A major sub-branch of cryptography and data hiding, which is a password generation unit, has been handled with steganography subjects. It can be seen that data encryption and data hiding are mostly using in providing information security. In this study, a complementary application was developed by using cryptography and steganography methods together. Thus, a new effective method for data security has been introduced and the implementation is coded in Visual C # programming language. With the application of the data, a mathematical model determined for encryption. In addition to these, a special cryptographic USB (Universal Serial Bus) dongle is developed and defined for authorized persons. The techniques developed for encrypting and hiding the data were examined on the images with various resolution and format. As a result of implementation, use of mathematical model developed for ciphering and cloaking of the text increased the data security.
