Şifrelenmiş Verileri Rast Gele Piksel Yaklaşımı ile Bir Görüntüye Gömme

Abstract

With the recent developments in information and communication technologies, data is transferred to digital environments. However, it has become very important to protect the information in digital environments. This situation raises the need for information security. Cryptography and steganography are among the most effective areas in ensuring information security. This study was carried out in order to contribute to information security by using cryptography at the point of making data meaningless by encrypting, and steganography at the point of hiding meaningless data. In this study, random pixel layout approach is used to hide the encrypted data into a 24-bit image. The proposed technique was examined on images with different file types and resolutions. The Structural Similarity Index Measure (SSIM), Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) parameters were revealed to measure the effectiveness of the proposed approach. It has been observed from the application that this method increases the security level of embedding data process.
