Abstract(in English) | In recent years, there has been an increasing movement in China to use personal credit scores in various situations such as lending, leasing, and share cycles. The use of credit scores is increasing overseas and in Japan. At present, one company calculates the individual’s credit score for each individual, so the method of calculating the individual’s credit score depends on the company at present. In addition, there is a privacy problem because a speci?c company or group manages personal information such as credit score calculation. On the other hand, by using the blockchain, which is the core of cryptocurrency, it is possible to transfer currency without passing through third parties. Blockchain is di?cult to falsify data including system administrators, and privacy information can be concealed because users are managed by address. Therefore, applications in various ?elds such as IoT data management are expected. In addition, the currency called ethereum has a mechanism that can execute automatic contracts called smart contracts without requiring a third party, in addition to the transfer of currency. Therefore, in this study, we propose a system that evaluates an individual’s credit score by using ethereum and does not depend on a single company for calculating an individual’s credit score, and proposes a business model using the system. We also show numerical results of the proposed scheme executed on the ethereum implemented in our laboratory. |
