Özet

Nowadays, with the widespread use of the internet, digital images are increasing in use rate. Digital images are attractive for creating a suitable environment for those who want to communicate securely. It is not easy to notice when substituting data into the least significant bit of these images, and the ability to embed excess data makes it attractive to make the use of steganography in secure communication. The aim of this paper is to provide secure communication via a new image steganography using LSB method with secret key and logistic map for generating random numbers. Also it is to compare to other approaches in the literature in term of image quality. As a result, it is seen that the PSNR is 55.91 at the maximum payload capacity namely 29127 bytes and is better than many other steganography algorithms in the literature.
