摘要

Nowadays, organizations in both public and private sectors have become increasingly dependent on digital communication and electronic data processing; when data is sent over the internet, it is necessary to utilize a robust method for protecting these data. To accomplish this task, we will create a new method based on the principle of Image Processing, Steganography and Cryptography. In this paper, we proposed an approach to hide the secret data in cover image: Firstly, encoding secret data using Huffman Coding; secondly, detecting the Straight Lines Pixels (SLPs) in a cover image by using Hough Transform. Posteriorly, embedding the encoded data in the SLPs by using Least Significant Bit method (LSB). The main purpose of this approach is the ability to increase embedded data in the image while preserving the image quality. The experimental results showed that the aforementioned proposed method is very efficient to hide data inside the image and provide a better Stego-Image quality.
