DISPATCH NO. 01/STATE BANK OF PAKISTAN FINANCIAL FRAUD AUDIT INITIATIVE

Explainable Document Forensics & Verification API.

“From academic matric and university certificates to commercial banking ledgers, synthetic document fraud is accelerating. DeepTrace delivers explainable, mathematically verifiable document forensics across all industries.”

Rather than probabilistic black boxes, DeepTrace combines sub-pixel typography baseline geometry, computer vision Error Level Analysis (ELA), cryptographic custody locking (ETO 2002), and deterministic math reconciliation to verify authentic educational credentials, utility bills, and financial statements with evidentiary certainty.

THE 8-STAGE DETERMINISTIC & CV PIPELINE
01 / CUSTODY LOCK

SHA-256 Sealing

Magic-byte header verification rejects extension spoofing; produces immutable append-only ETO 2002 custody events.

02 / STRUCTURE & METADATA

Incremental Saves

Exposes multiple %%EOF trailers and signatures from Canva, Photoshop, or Acrobat Pro DC with timestamp divergence.

03 / SUB-PIXEL GEOMETRY

Baseline y-Jitter

Measures median vertical baselines across rows. Catches manual desktop insertions with >0.75 pt offset.

04 / FINANCIAL MATH

Lakh/Crore Reconciler

Deterministic row-by-row equation audit across Pakistani banking numbering formats and ISO 7064 MOD-97 IBANs.
