What is an Open Badge?
A guide for learners, employers, and anyone who has received or been shown a digital badge
An Open Badge is a digital credential — a verifiable, tamper-proof record of an achievement that a learner can share online. Unlike a PDF certificate or a screenshot, an Open Badge carries cryptographic proof of who issued it, when, and to whom. Anyone can independently verify it hasn't been faked, altered, or revoked.
What's inside a badge?
Every badge issued through Creatio is an Open Badges 3.0 credential — a digitally signed document that contains:
- Who earned it — identified by a cryptographic identifier linked to the learner's email address
- What was achieved — the qualification or unit name, criteria, and any units completed
- Who issued it — the awarding organisation, identified by a public DID (Decentralised Identifier)
- When it was issued — and when it expires, if applicable
- A digital signature — produced by the issuer's private key; undetectable if tampered with
- A revocation status — a live check against the issuer's public status list
This data is baked into the badge image file (PNG or SVG) and embedded in PDF certificates, so the proof travels with the badge wherever it goes.
How is this different from a PDF certificate?
| Feature | PDF certificate | Open Badge (OB3) |
|---|---|---|
| Can be independently verified | ✗ No — relies on trust in the document | ✓ Yes — cryptographic proof |
| Tamper detection | ✗ Not detectable without the issuer | ✓ Any modification breaks the signature |
| Can be revoked and checked live | ✗ No mechanism | ✓ Real-time revocation status |
| Shareable on LinkedIn | ✗ Manual / screenshot only | ✓ Direct LinkedIn profile integration |
| Embeds in wallets | ✗ No | ✓ Google Wallet, Apple Wallet |
| Human-readable share page | ✗ No standard | ✓ Public URL with full credential details |
How the trust chain works
Open Badges 3.0 uses the same public-key cryptography that secures the web. The trust chain works like this:
The issuer's public key is published at a stable, well-known URL (a DID document). Anyone can fetch that key and use it to check whether the badge's signature is genuine — without contacting the issuer. This is what makes Open Badges independently verifiable.
