Data Security Scheme for Multiple Attribution Information in Big Data Environment

Recently, as the installation and deletion of not only the Internet but also applications have become easy without any time or place constraints through 3G networks as well as other diverse interfaces such as Wi-Fi and Wibro, the amounts of data are increasing and the kinds of data are being diversified. However, socially large repercussions are arising because methods of protecting user data are insufficient. In the present paper, a security scheme is proposed that will link big data to attribution information to enable users to be provided with big data services from different networks in real time. The proposed scheme inserts attribution information at the beginning and end of contents for provision of big data contents services in real time so that both authentication and non-repudiation can be provided for the contents even if one of the two signatures is lost. In addition, the proposed scheme enhanced the security of contents data by transferring hash chain values to prevent attribution information from being unnecessarily exposed to any 3rd party.
