本文针对现有第三方合规评估的局限性，提出基于区块链的第三方风险评估（TPRA）框架，结合评估指标与成熟度模型，实现对合规控制的可验证、持续的实施与治理。
AI 中文摘要
NIST SP~800--53、ISO/IEC 27001、GDPR、HIPAA等网络安全与隐私框架被广泛用于指导组织安全态势与监管合规。但实践中，框架采用常通过时点审计、自我声明和碎片化证据审查评估，难以保证控制措施被持续实施、独立验证和长期维持，在依赖第三方供应商的环境中尤其突出；在医疗远程患者监测（RPM）等多供应商生态中，合规义务跨组织边界，且由多个独立评估方开展，这些限制被进一步放大。本文研究许可型区块链系统如何支持框架实施成熟度测量而非静态合规验证，提出基于区块链的第三方风险评估（TPRA）框架，通过可编程智能合约实现评估工作流、执行多方治理并保留纵向评估状态；在此框架基础上，引入一组评估指标和定性成熟度模型，用于评估合规控制措施是否在重复评估周期中被可验证地实施、治理和维持。
英文摘要
Cybersecurity and privacy frameworks such as NIST SP~800--53, ISO/IEC~27001, GDPR, and HIPAA are widely used to guide organizational security posture and regulatory compliance. In practice, however, framework adoption is often assessed through point-in-time audits, self-attestations, and fragmented evidence reviews, providing limited assurance that controls are consistently implemented, independently validated, and sustained over time, particularly in environments that rely on third-party vendors. These limitations are amplified in multi-vendor ecosystems, such as healthcare remote patient monitoring (RPM), where compliance obligations span organizational boundaries and assessments are conducted by multiple independent assessors. This paper investigates how permissioned blockchain systems can support framework implementation maturity measurement rather than static compliance verification. We propose a blockchain-based Third-Party Risk Assessment (TPRA) framework that operationalizes assessment workflows, enforces multi-party governance, and preserves longitudinal assessment state using programmable smart contracts. Building on this framework, we introduce a set of evaluation metrics and a qualitative maturity model designed to assess whether compliance controls are verifiably implemented, governed, and sustained across repeated assessment cycles.
