Multiple layers security in protecting Arabic sensitive information using stenography and cryptographic algorithms
Ahmad B. Elmadani · 2013
Needs to find other alternatives in protecting sensitive information, became nowadays one of the hottest topics. As we know there are a lot of cryptographic algorithms to do so, but some are slow other are time consuming or are unsecure, therefore more researches are needed in this area. This paper presents an algorithm that uses an image to hide a text massage. The text massage is first converted to a digital massage using a unif8 code, Cryptographic key are used to encrypt secret message, then hidden it within an image. An image can be sent to the receiver through unsecure channel. An encrypted message can be retrieved if the receiver knows the cryptographic key. As result of the purposed algorithm, security of sensitive information is enhanced because there were no differences between original image and the processed image. Image size, color and transfer speed were not affected even with the use of non Latin languages message such as an Arabic.
