Information Security for Secret Data Transmission over Web Services

Abstract

Information hiding technique is becoming a research hotspot in information security, and will be widely used to national security, e-commerce, egovernment, copyright protection and covert communication. This paper proposes secure, efficient capacity and undetectable hiding algorithm to be used for XML document and the secret message is hidden in cover XML according to the pseudorandom number generator which makes this system more secured. The proposed steganography algorithm, which is different from all steganographic algorithms in XML and text file that uses XOR logical operation and mathematical operation to hide secret data. All other algorithms which hide information by inserting white space in XML tag, rearranging the order of XML elements etc. This paper also developed a secure system in which cryptography and steganography are used as integrated part along with newly developed enhanced security model for web services. In Steganography the secret message is hidden in (Simple Object Access Protocol) SOAP message according to the proposed hiding algorithm. In Cryptography public key (RSA) algorithm is used to encrypt the key for extracting process. This technique is empirically validated to indicate its utility and value.
