Submitting fake certificates is a common problem in Southeast Asia, which prevents qualified candidates from getting the jobs they deserve. When applying for a job, students must provide academic credentials as proof of their qualifications, acquired both inside and outside the classroom. Verifying academic documents before hiring is crucial to prevent fraud. Employing blockchain technology has the potential to address this issue. Blockchain provides an electronic certificate that is tamper-proof and non-repudiable, making it difficult for students to manipulate their academic credentials. This paper presents a prototype for an academic credential verification model that leverages the security features of blockchain and IPFS (Interplanetary File System). Certificates are temporarily stored in a database before being transferred to IPFS, where a unique hash code is generated using a hashing algorithm. This hash code serves as the certificate's unique identity and is stored in the blockchain nodes. Companies can verify an applicant's credentials by searching for the applicant and accessing their already verified certificates. Utilizing IPFS as a middleman storage platform lowers the expenses of directly storing massive data on the blockchain. To sum it up, the proposed solution would make the process of certificate verification more efficient, secure, and cost-effective. It would save time and resources that would otherwise be used to manually verify certificates.

翻译：在东南亚，提交伪造证书是一个常见问题，这导致符合条件的候选人无法获得应得的工作。求职时，学生必须提供在课堂内外取得的学历证明作为资质凭证。在招聘前验证学术文件对于防止欺诈至关重要。采用区块链技术有望解决这一问题。区块链提供不可篡改且不可否认的电子证书，使学生难以篡改其学术凭证。本文提出了一种基于学术凭证验证模型的原型，该模型利用了区块链和IPFS（星际文件系统）的安全特性。证书在传输至IPFS前暂存于数据库中，IPFS通过哈希算法生成唯一哈希码。该哈希码作为证书的唯一标识，被存储在区块链节点中。企业可通过搜索申请人并访问其已通过验证的证书来核实其资质。利用IPFS作为中间存储平台，可降低将海量数据直接存储于区块链的成本。总之，所提出的方案将使证书验证过程更高效、更安全且更具成本效益，从而节省了原本用于人工验证证书的时间和资源。
