Combine Elliptic Curve Cryptography with Digital Watermark for OWL-Based Ontology Encryption

Although progress has been made on semantic Web during the past decades, security is still one of the major challenges in the development of semantic Web. Elliptic curve cryptography (ECC) serves as an excellent candidate because of its small key size and high security protection. Digital watermark is the practice of hiding a message within that work itself. In this paper, a novel method is proposed to combine elliptic curve cryptography with digital watermark for OWL-based ontology encryption.
