A trust score out of 100 for every loan document

Banks receive salary certificates, bank statements and IDs as PDFs and photos, and a small share are edited. We are building a tool with a banking domain partner that scores each document for signs of tampering and explains every flag in plain language.

Document check screen: a bilingual salary certificate on the left, a trust score of 42 out of 100 on the right with the arithmetic and font checks that failed, and a magnified view of the altered total

Background

A banking professional with years in UAE lending came to MornningStar with a clear problem: reviewers cannot check every document deeply, and the tools on the market give a yes-or-no answer nobody can defend to a regulator. MornningStar is the technical builder; the partner brings the banking knowledge.

Challenge

A useful score has to be explainable. Documents are in Arabic and English, often mixed. And the best checks, like matching against genuine bank templates, need real documents that only a bank partner can provide.

What we are building

  • A scoring engine that returns a trust score out of 100 with a list of reasons, not a single verdict
  • Metadata checks: creation and edit history, software used, inconsistencies
  • Font and layout checks that catch pasted-in numbers and names
  • Arithmetic checks: do the totals, balances and salaries actually add up
  • Language checks using Claude: wording that does not fit a genuine issuer
  • Bilingual Arabic and English OCR, with a plan to fine-tune on real bank documents in the pilot

Tools used

Claude and Claude Vision APIs, Python document forensics, PaddleOCR / EasyOCR, Vercel.
