Can We Trust Digital Marksheets? Meet Adaptive Trust Scoring with Generative AI and Blockchain.
In a world full of digital degrees and online credentials, one big question remains: Can we trust what we see? Let’s explore how Generative AI and Decentralized Identity are working together to solve this problem in education.
The Big Problem with Digital Credentials
As students shift to online learning and digital degrees, marksheets are now being issued in electronic formats. While this saves time and paper, it brings a serious challenge: How do we verify if a digital marksheet is real or fake?
Fake degrees are flooding the internet. Traditional systems are slow, centralized, and easy to hack or manipulate [1]. That’s where blockchain, SSI (Self-Sovereign Identity), and AI come in.
What is Decentralized Identity (DID) and SSI?
Imagine your student ID, marksheet, or certificate stored in a secure app on your phone. You own it. You control who sees it. This is the power of Self-Sovereign Identity (SSI) [2].
Here’s how it works:
- A university issues a Verifiable Credential (VC) (a digital marksheet).
- The student stores it in an SSI Wallet (e.g., Trinsic or Bloom).
- When needed, the student shares it with institutions or employers.
Now comes the tricky part: How can others trust this digital document?
Why Trust Still Matters
Even with blockchain-based credentials, trust is not automatic. Institutions still ask:
- Is the university legitimate?
- Has this document been altered?
- Is the data consistent and up-to-date?
Currently, there is no smart system that automatically rates the trustworthiness of a digital credential.
Enter Adaptive Trust Scoring with Generative AI
We propose a game-changing solution: Adaptive Trust Scoring using Generative AI.
Imagine an AI model that:
Reads your digital marksheet, Checks the issuing authority and document format.
Compares it with verified historical data, Calculates a real-time trust score (like 87% trustworthy)
The result? Institutions and recruiters get instant, intelligent, and data-driven decisions—without needing to verify manually.
Research shows that Generative AI like GPT-4 or BERT can detect patterns, anomalies, and inconsistencies far better than traditional tools [4].
How the System Works
Step-by-step:
1. 🎓 University issues a digital marksheet (VC) using blockchain and DIDs [3].
2. 📲 Student saves it in their SSI wallet.
3. ⚙️ Generative AI engine reads the marksheet and issuer info.
4. 📊 It analyzes metadata, compares it to trusted data, and flags anomalies.
5. 🔐 A trust score is generated (e.g., 91%)—all in seconds!
🔗 Why Blockchain Matters
Blockchain ensures:
🔒 Tamper-proof data
👀 Public verifiability
🧩 No central control
Blockchain tools like Ethereum, Polygon, and Hyperledger Indy are used in many global SSI systems [5].
