As the world is gradually moving towards digitization, forgery of vital digital documents has become relatively easy. Therefore, the need for efficient and secure verification and authentication practices of digital documents is also increasing. Self-sovereign identity (SSI) is a set of technologies that build on core concepts in identity management, blockchain technology, and cryptography. SSI enables entities to create fraud-proof verifiable credentials and instantly verify the authenticity of a digital credential. The online document verification solutions must deal with a myriad of issues in regard to privacy and security. Moreover, various challenging and tedious processes have made document verification overly complex and time-consuming which motivated us to conduct this research. This work presents a novel framework for online document verification based on SSI technology. The solution address the complexity and interoperability issues that are present in the current digital document verification systems. We look at a particular use case, i.e., document verification in online loan processing and evaluate how this proposed approach can make an impact on the existing system. Our solution based on SSI standards replaces the intermediary and enables trust between players in the ecosystem. The technology also holds the potential to make the system more efficient, interoperable, and privacy-preserving.
随着世界逐渐走向数字化，重要数字文档的伪造变得相对容易。因此，对数字文档进行高效、安全验证和认证的需求也在不断增加。自主身份 (SSI) 是一组构建于身份管理、区块链技术和密码学核心概念之上的技术。SSI 使实体能够创建防欺诈的可验证凭据，并即时验证数字凭据的真实性。在线文档验证解决方案必须解决隐私和安全方面的众多问题。此外，各种具有挑战性和繁琐的流程使得文档验证过于复杂和耗时，这促使我们进行了这项研究。这项工作提出了一种基于 SSI 技术的在线文档验证新框架。该解决方案解决了当前数字文档验证系统中存在的复杂性和互操作性问题。我们研究了一个特定的用例，即在线贷款处理中的文档验证，并评估了这种新方法如何对现有系统产生影响。我们基于 SSI 标准的解决方案取代了中介，并在生态系统中的参与者之间建立了信任。该技术还有可能使系统更高效、互操作和保护隐私。
