Detect tampered and deepfake Degree Certificate
A degree certificate carries almost no data, which is what makes it hard to check and easy to forge. There is a name, a degree, a classification, a date, and two signatures, and none of those fields can be tested against another field the way a transcript's figures can. The security lives in the paper instead: an embossed seal, a guilloche background, foil. TamperCheck works on those, separating an impression pressed into a sheet from one printed flat onto it.

What a genuine degree certificate contains
A degree certificate is a single sheet recording a conferral. It names the university and carries its crest, states the graduate's full legal name as the institution holds it, the degree awarded written out in full rather than in initials, the field of study, and the classification or honours where the institution awards one. Below that sit the conferral date, often a specific congregation date, the place of conferral, and signature blocks for the chancellor or vice-chancellor and the registrar. A serial or certificate number usually sits in a margin, and the sheet itself is printed on security stock.
What constrains these fields is the institution's own practice rather than arithmetic. A university awards a fixed set of classifications in fixed wording, confers degrees on published dates, and uses a degree title it actually offers, so First Class Honours in a programme graded only pass or fail, or a conferral date falling outside any congregation held that year, is wrong before the paper is examined. The remaining constraints are physical. The seal is embossed, the background is line-engraved guilloche, and the classification must agree with the transcript that sits behind it.
How degree certificate forgeries are made
Classification upgrade
The single most common edit on this document: a lower second becomes an upper second, a pass becomes a distinction, a cum laude appears where none was awarded. Two or three words change on an otherwise authentic certificate belonging to the person presenting it.
Graduate name replacement
A genuine certificate is reused under a different name. Universities set names in a specific display face, often with wide manual letterspacing, and a substituted name rarely reproduces both, so the new text sits slightly off the baseline or at a different weight from the surrounding wording.
Award date shifted
The conferral date is moved to close a gap in an employment history or to place a qualification before a job application that required it. Conferral happens on a handful of congregation dates each year, so an invented date frequently falls on a day the university held no ceremony.
Embossed seal printed flat
The university seal on a real certificate deforms the sheet and catches light along its raised edges. Photographed and reprinted, it arrives as an even layer of ink with no relief, no directional shadow, and none of the fibre disturbance that pressing leaves behind.
Guilloche captured by scanning
The engraved line background is designed to fail when copied. Scanned and reprinted, the continuous fine lines break into halftone dots and interference patterns, and the density of the pattern drops in a way that is measurable even where it looks correct to the eye.
Degrees from unaccredited awarding bodies
Diploma mills print genuinely, on good stock, with real embossing. Forensic analysis will not call these forged because they are not forged, and resolving them means asking a different question: whether the body that issued the degree is recognised, and whether any study took place.
What TamperCheck checks on a degree certificate
TamperCheck runs 200+ forensic checks across three layers and returns a risk score from 0 to 100 with plain-English findings tied to specific regions of the document. These three carry the most weight on this document class.
Security print, foil, and hologram analysis
A genuine security overlay or guilloche background behaves differently from a printed picture of one. A reproduction loses the structure that made the feature a security feature in the first place, and that loss is measurable even when the copy looks convincing on screen.
Embossed seal analysis
A physically embossed seal deforms the paper it sits on. A seal that was scanned and reprinted is flat, and the two separate cleanly under analysis even when they are hard to tell apart by eye.
Signature forgery analysis
Signature regions are assessed for ink consistency and for how the stroke sits on the page, which distinguishes a genuine pen stroke from a pasted image of one.
And many more checks
The three above are the layers that carry the most weight on a degree certificate. Every upload runs the full suite of 200+ checks regardless of document class, spanning file structure and metadata, pixel-level forensics, font and text rendering, optical and print characteristics, provenance signals, AI-generation signatures, and many more checks.
Who verifies a degree certificate, and why
Recruiters, universities, and licensing bodies validating credentials. In each case the document is being used to unlock money, access, or a legal status, which is exactly what makes it worth forging.
How to verify a degree certificate in 4 steps
Check the fields against each other
Read degree classification, graduate name, and award date together rather than one at a time. Forgers typically change one value and leave the rest of the document describing the original.
Inspect the file metadata
Open the document properties and look at the producer, creation date, and modification date. A document produced by a consumer PDF editor, or created long after the date printed on its face, is worth a closer look.
Ask for a second document
Request a corroborating document from the same issuer or an adjacent period. Forgery effort concentrates on one file, so inconsistencies surface as soon as there are two to compare.
Run a forensic check
Manual review catches obvious edits but not field-level pixel manipulation or synthetic generation. TamperCheck runs 200+ forensic checks on a degree certificate and returns a risk score from 0 to 100 within seconds, at $0.50 per document.
Frequently asked questions
How do employers check if a degree is fake?
The reliable route is the university's own verification office or a national credential verification service, which confirms the award, the classification, and the conferral date against the institution's records. Before that, employers examine the certificate itself: whether the seal is embossed, whether the classification wording matches what the institution awards, and whether the printed classification agrees with the transcript supplied alongside it.
How can I tell if a degree certificate is genuine?
Run your thumb over the seal, because embossing is the element forgers most often lose. Then check that the degree title and classification are ones the institution actually awards in that wording, that the conferral date falls on a real congregation, and that the security background prints as continuous engraved line rather than as a pattern of dots visible under magnification.
What is a diploma mill?
A diploma mill is an organisation that sells degrees for money rather than study, usually with no meaningful assessment and no recognised accreditation behind it. The certificates it issues are genuine products of that organisation, which is why document forensics will not flag them as altered. They are identified by investigating the awarding body, not the sheet of paper.
Does the classification on a certificate have to match the transcript?
Yes, and the mismatch between the two is one of the most productive checks available. The certificate states a classification; the transcript contains the grades that classification was calculated from. A candidate who upgraded one document and not the other leaves the pair disagreeing, which is why credential checks ask for both rather than either.
Can a degree certificate be verified from a scan?
Partly. A scan preserves typography, layout, security print structure, and the compression history of every region, so edits to the name, classification, or date are detectable. What a flat scan loses is the depth information in an embossed seal, so a high-resolution photograph taken under raking light is worth sending alongside it.
