Anonymity Management Based on Segmentation and Restoration Scheme for Content Identifier in Future Internet Environment

摘要

The potential of future Internet environment is expanding due to development of information and communication technology. It is expected that the number of objects connecting to the Internet will increase by billions, even excluding PCs, tablets and smart phones. As the number of devicesconnecting increases a numerous amount of data including personal information combining with external environmental information is exchanging. Therefore, it is necessary to share collected information at a minimum level by a legitimate user for the original purpose and control access rightto data if necessary. While existing network infrastructure uses a path to exchange data between a data center and a terminal, future infrastructure actively makes a decision about the whole process from data generated by various objects to utilization and independently plays major roles includinga service supporting function of a data center. This paper discusses a safe sharing management scheme of content identifiers. This paper proposes a system for safe management of identifiers using secret sharing and AES Cryptography algorithm as a separation and restoration scheme for identifiers.Sensitive identifiers can be safely saved and managed through such identifier separation system. In addition, they are safe in moving by segmenting and restoring an identifier through mobile device interfaces such as a smart phone.
