| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In order to promote data distribution and utilization of personal data, the concept of data portability attracts attention. As an example of such personal data, there is a study document of a high school student used for entrance examination etc. Since study documents are still paper medium in Japan, computerization of study documents is planned. However, since a study document contains a lot of confidential information, the information must not be leaked even if erroneous transmission or mistake occurs. In addtion, it is necessary to prevent falsification of information. The format of a study document are now planned to be updated by Ministry of Education, Culture, Sports, Science and Technology, and, in a updated study document, not only teachers input information but also student him/herself also conducts research activities, extracurricular activities, qualifications/certification etc. Consequently, the authority of input/viewing becomes extremely complicated. In this paper, we propose a digital study documents system by using smart contract on blockchain. Furthermore, we implement the proposed system using Ethereum platform. Due to the nature of the blockchain, the falsification of information is extremely difficult, information leakage is prevented by combining with encryption, and it is effective from the viewpoint of data portability. | |
