Information hiding in linked opened data

الملخص EN

Information hiding is very important for securing an information from the malicious attackers.

Steganography is the science of hiding the original information (message) into a carrier.

The user of the internet usually need to store, send and receive a private information.

One of the most famous method for doing this is the encryption, which it converts the information into another format that is not understood to attackers.

The major drawback of the encryption is that it cannot hide the existence of the data, because the result is still data so if there is enough time someone may decrypt the encrypted data.

The steganography is the solution for this problem.

The Linked data are the idea for linking different web data sources by establishing a link between them.

The link describes the relationships between all these sources.

The main idea about this paper is securing the important information inside Linked opened data .

Usually, for embedding secret information into a cover message we need redundant data or noise, therefore, we use the least important features in the RDF to hide our important information.

In order to increase the security of our important information we encrypt it using the Beaufort cipher.

We implement the proposed method using two RDF representation for Alzheimer disease and Amyloid precursor protein and give accepted security for our important information.
