English Abstract

Steganography is the approach by which data is hidden such that one cannot know about it and so data remains secure, this is usually done by hiding data inside an object through changing some properties of that object, this is often called the cover object.

In this thesis, a novel steganography technique based on Quick Response code (QR code) and colored images is proposed, the technique hides secret text in QR code, before hiding the QR inside the four channels PNG cover image, the QR is saved as black and white image with 1 bit per pixel and is stored in array of bytes to be encrypted using AES before embedding it inside the cover image.

The results of the technique was superior when using large data, despite the fact that the impact is greater when using the first and third bits than when using the least significant bit alone, the proposed technique was tested by 3 experiments using 600, 65536 and 131070 characters as secret text, the effect of the proposed technique on the picture was almost the same and even better in some images than LSB when hiding relatively large data.
