An ISMS is established in accordance with the requirements of ISO / IEC 27001, "Information Technology Security - Requirements for Information Security Management Systems," a development of BS 7799-2. An ISMS is a standard for establishing and maintaining an ISMS. It requires organizations to establish an ISMS by defining its scope, developing an information security policy, clarifying management responsibilities, and selecting control objectives and methods based on risk assessment. Customer information security management is a crucial issue in the business world. Blockchain technology can achieve decentralized and secure protection of customer personal information in the commercial, financial, and educational sectors.
