Security, Encryption image, Steganography, Development and challenges, Evaluation parametersAbstract
Modern Internet technologies have led to an increase in the transmission and receiving of information across the network, especially images that may contain confidential information, so it has become necessary to increase protection for these images. The processes of protecting information during the transmission are scientifically divided into encryption and hiding techniques. Encryption techniques change the secret data content to become unclear for professional hackers. On the contrary, steganography saves the same content of secret data but inserts it in the medium cover without clearly showing any change in the medium. These covers, such as text, images, or video, whereas images and video are more efficient than other covers because they have powerful and complex structures to achieve more security. The combination of hybrid encryption and steganography gives more multi-leveled security protection, which is hardly predictable against intruders. This work analyzes the challenges that may face researchers in this field, in addition to discussing the latest technologies proposed. Besides that, the evaluation parameters of these techniques are summarized.
