The smart contract of the block chain is a technology that guarantees the reliable contract without intermediary third party, and various studies are being carried out in various fields. When smart contracts are placed on the block chain, if the sensitive information of the contracting parties is registered, it may become an example of infringement of personal information. However, research on privacy and information protection among the research using the block chain smart contract seems to be insufficient. In this paper, we propose a design method to solve this issue by deriving the issue of reliable block chain smart contract and contribute to making it safe to use in P2P distributed network environment through case study.
