ISO 22388の概要と活用

抄録

This paper presents ISO 22388:2023 "Guidelines for securing physical documents," an international standard developed to enhance the security of physical documents, such as vouchers, identity cards, and certificates. The standard specifies entities, including government agencies, document issuers, and solution providers, using a structured approach to assess fraud risks, define document classes based on exposure levels, and establish the minimum recommended security features. By promoting a risk-based methodology, ISO 22388 supports consistent decision-making in document design and issuance, helping to prevent counterfeiting, unauthorized alterations, and theft. In addition, these guidelines encourage interoperability and trust across jurisdictions by offering a common framework for evaluating threats, vulnerabilities, and asset values. This study investigated how this standard can be effectively applied to diverse operational contexts, including public administration, financial services, and identity management. It also analyzed how ISO 22388 complements existing security frameworks and regulatory requirements, and how it may evolve in response to emerging threats and stakeholder feedback.
