Detect tampered and deepfake Marksheet

What a genuine marksheet contains

A marksheet is an examining board's record of one examination session. The head carries the board or university name, the examination and its session, the candidate's name and parents' names where the board records them, the roll number, and the registration or enrolment number. The body is a table of subjects: subject code, subject name, maximum marks, marks in theory, marks in practical or internal assessment, and the subject total, often repeated in words as well as figures. The foot holds the grand total, the percentage or CGPA, the result status, the division or class, the date of declaration, the controller of examinations' signature, and the board seal.

The relationships here run in one direction and are easy to test. Theory and practical marks add to the subject total, subject totals add to the grand total, the grand total over the aggregate maximum gives the percentage, and the percentage falls into a division band the board publishes and does not vary. Marks written in words have to agree with the same marks in figures. A sheet whose grand total does not equal the sum of its rows, or whose division sits above the band its own percentage earns, is contradicting itself before anyone looks at the paper.

How marksheet forgeries are made

• Subject mark inflation

  Marks in one or two weak subjects are raised, typically from just below a pass to comfortably above it. The digits are re-set inside an otherwise authentic cell, and the grand total printed at the foot still reflects what the candidate actually scored.

• Aggregate and percentage rewrite

  The grand total and percentage are edited too, so the column adds up. What survives is the words-and-figures pair many boards print: the total in figures is updated and the same total spelled out in words is forgotten, leaving two different numbers on one line.

• Division upgraded on its own

  No mark is touched and only the class line changes, so Second Division reads as First. It is the fastest edit available on this document and the easiest to disprove, because the percentage two lines above it still sits in the lower band.

• Failed subject replaced with a pasted row

  A compartment or fail row is covered with a passing row lifted from another sheet, and the result status is switched to PASS. Pasted rows inherit the source sheet's background tone and rarely align to the rule lines of the table they were dropped into.

• Roll number and candidate name substitution

  A strong candidate's genuine marksheet is re-issued under someone else's name, or the roll number is changed so a result can be claimed by a different person. Because the marks are authentic, everything reconciles and the tell is in the substituted characters themselves.

• Board seal and hologram sticker reproduction

  Boards protect marksheets with embossed seals, security paper, and applied holographic stickers. Reproduced by print shops, the sticker becomes a printed rectangle with fixed colours instead of an element that shifts as the sheet moves, and the seal loses its impression entirely.

What TamperCheck checks on a marksheet

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.

• 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.

• Arithmetic reconciliation

  Stated totals are recomputed from their components, and running or cumulative figures are checked for continuity across periods. A single edited value breaks the chain even when the page still looks right.

• Table structure integrity

  Inserted and deleted rows leave structural artifacts behind: inconsistent spacing, misaligned columns, and formatting the visible table no longer accounts for.

• And many more checks

  The three above are the layers that carry the most weight on a marksheet. 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 marksheet, and why

Universities and recruiters screening academic records at admission or hire. 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 marksheet in 4 steps

1. 1

   Add the subject rows up yourself

   Total the theory and practical marks for each subject, add the subject totals, and compare the result with the grand total printed at the foot of the sheet. Where marks appear both in figures and in words, confirm the two agree.

2. 2

   Check the division against the percentage band

   Divide the grand total by the aggregate maximum and compare the percentage with the division or class awarded. Boards publish fixed bands, so a class that sits above the band the percentage earns is a contradiction the sheet cannot resolve.

3. 3

   Look the roll number up on the board's result portal

   Most examining boards and universities publish results by roll number for several years after declaration. Enter the roll number and session from the sheet and compare the subject marks returned against the ones printed in front of you.

4. 4

   Analyse the sheet forensically

   A well-made edit reconciles arithmetically and passes a portal lookup done from the wrong number. TamperCheck analyses the sheet through a single REST endpoint and delivers a verdict within seconds, naming the field that was edited.
