What types of documents can Turing Verify check?

Turing Verify supports diplomas, university degrees, transcripts, professional certifications (AWS, CPA, CFA, PMP, CompTIA), government IDs (national IDs, driver licenses, healthcare IDs), insurance cards, employment verification letters, offer letters, and trade-association credentials.

How accurate is Turing Verify at detecting fake documents?

Turing Verify runs a 50-pattern forensic analysis framework called V50-MASTER+ID. It examines visual, typographic, metadata, data-integrity, and AI-generation signals, and returns a confidence score per pattern so reviewers can audit the verdict instead of getting a black-box answer.

How long does document verification take?

Most documents finish in under 30 seconds. The pipeline runs visual forensics, metadata inspection, internal data-logic checks, and registry cross-reference in parallel, far faster than the 3-to-14 days a manual registrar verification typically takes.

Is Turing Verify free to use?

Yes. The free tier includes 3 verifications per month. Paid plans start at EUR 9 per month (Personal, 15 verifications), EUR 29 per month (Pro, 150 verifications), and EUR 99 per month (Business, 500 verifications with API access). Enterprise pricing is custom.

Is Turing Verify GDPR-compliant?

Yes. Inference runs on EU-resident infrastructure. Documents are processed in memory and not retained unless the user explicitly opts in. The DPA and sub-processor register are public on the Trust page.

Who uses Turing Verify?

HR and talent-acquisition teams screening candidate credentials, university admissions and registrar offices verifying transcripts and foreign degrees, banks and fintechs running KYC, insurance teams detecting claims fraud, and licensing boards authenticating professional credentials.

Can Turing Verify detect AI-generated fake documents?

Yes. The pipeline targets diffusion-model and GAN signatures, synthetic-text patterns, and statistical anomalies in pixel distributions, failure modes that purely visual reviewers miss.

Document Verification Glossary

Definitions for key terms in document verification, fraud detection, forensic analysis, and compliance.

Document Verification

Document Verification: The process of authenticating the legitimacy of a document by examining its content, format, metadata, and physical or digital properties to confirm it has not been forged, altered, or fabricated.
Credential Authentication: Verifying that a credential (degree, certificate, license, or ID) was legitimately issued by the claimed institution and has not been tampered with.
Forensic Document Analysis: The application of scientific techniques to examine documents for signs of forgery, alteration, or fabrication. Includes analysis of typography, inks, paper, digital metadata, and image manipulation artifacts.
V50-MASTER+ID: Turing Verify's proprietary forensic analysis framework that examines documents across 50 distinct verification patterns organized into typography, visual forensics, data cross-reference, metadata inspection, and AI-generation detection categories.
Confidence Score: A numerical value (typically 0–100%) indicating the likelihood that a document is authentic, based on the aggregated results of multiple forensic analysis patterns.
Verification Certificate: A digitally signed record confirming that a document has been analyzed and verified. Includes a confidence score, verification date, and a unique identifier for re-verification.
Verification Badge: An embeddable visual indicator that can be placed on websites, email signatures, or documents to show that a credential has been verified by Turing Verify.

Fraud Detection

Document Fraud: The act of creating, altering, or misusing documents to deceive others. Includes forged diplomas, fake certificates, altered transcripts, counterfeit IDs, and AI-generated documents.
Diploma Mill: An organization that sells academic degrees and diplomas with little or no legitimate academic study required. Diploma mills may produce documents that appear legitimate but lack proper accreditation.
Credential Fraud: Presenting false, altered, or misrepresented credentials (degrees, certifications, licenses) to gain employment, admission, or professional standing.
Forgery: The creation of a false document or the unauthorized alteration of a genuine document with intent to deceive.
Tampering: The unauthorized modification of a genuine document, such as changing dates, names, grades, or other information while preserving the overall appearance of authenticity.
Counterfeit Document: A fraudulent document created to closely imitate a legitimate document from a specific institution, often using replicated logos, seals, signatures, and formatting.

Forensic Techniques

Error Level Analysis (ELA): A digital forensic technique that identifies areas of an image that have been modified by analyzing compression artifacts. Edited regions typically show different error levels than the surrounding unmodified areas.
Metadata Analysis: Examining the hidden data embedded in digital files, including creation dates, software used, modification history, author information, and GPS coordinates for photographs.
Typography Analysis: Examining fonts, character spacing, kerning, baseline alignment, and text rendering to detect inconsistencies that may indicate document manipulation or fabrication.
Watermark Verification: Checking the presence, placement, and integrity of watermarks embedded in documents as security features. Authentic watermarks have consistent patterns that are difficult to replicate.
Seal Authentication: Analyzing official seals and stamps on documents for shape regularity, ink distribution, pressure patterns, and consistency with known genuine seals from the issuing institution.
Digital Signature Validation: Verifying cryptographic digital signatures embedded in PDF documents to confirm the document was signed by the claimed entity and has not been modified since signing.
AI-Generated Document Detection: Identifying documents created using artificial intelligence tools (GANs, diffusion models, large language models) by detecting synthetic text patterns, image generation artifacts, and statistical anomalies.
Compression Artifact Analysis: Examining JPEG or other compression artifacts in document images to detect splicing, editing, or regions that have been re-saved at different quality levels.

Compliance & Due Diligence

KYC (Know Your Customer): A regulatory requirement for businesses to verify the identity of their clients. In document verification, KYC involves authenticating identity documents and credentials as part of customer onboarding.
KYB (Know Your Business): Due diligence on business entities, including verifying the legitimacy, registration, accreditation status, and reputation of organizations that issue documents or credentials.
GDPR (General Data Protection Regulation): European Union regulation governing the collection, processing, and storage of personal data. Document verification services handling EU residents' data must comply with GDPR requirements.
Data Processing Agreement (DPA): A legally binding contract between a data controller and data processor that governs how personal data is handled, required under GDPR when personal data is processed by a third party.
EU Data Residency: The practice of storing and processing data within the European Union to comply with data sovereignty requirements and GDPR regulations.
Accreditation: Official recognition that an institution meets established quality standards. Accreditation bodies evaluate educational institutions and certifying organizations to ensure they meet minimum standards.
Background Check: A process of verifying an individual's credentials, employment history, education, and other claims. Document verification is a key component of comprehensive background checks.

Document Types

Academic Transcript: An official record of a student's academic performance, including courses taken, grades received, and degrees awarded, issued by an educational institution.
Professional Certification: A credential awarded by a professional body or organization confirming that an individual has met specific competency requirements in a field (e.g., AWS, CPA, PMP, CompTIA).
Employment Verification Letter: A document issued by an employer confirming an individual's employment status, job title, dates of employment, and sometimes salary information.
Offer Letter: A formal document from an employer offering a position to a candidate, typically including job title, compensation, start date, and terms of employment.
Healthcare ID: An identification card issued by a healthcare system or insurance provider (e.g., Medicare, Medicaid, NHS card, EHIC) confirming enrollment or coverage.

Technology

OCR (Optical Character Recognition): Technology that converts images of text into machine-readable text. Used in document verification to extract and analyze text content from scanned or photographed documents.
GAN (Generative Adversarial Network): A type of AI model that can generate realistic synthetic content. GANs can be used to create fake documents, and GAN-detection techniques are used to identify such forgeries.
Diffusion Model: A type of generative AI model that creates content by gradually removing noise from random data. Can generate realistic images and documents that require specialized detection methods.
Batch Verification: Processing multiple documents simultaneously rather than one at a time. Useful for organizations that need to verify large volumes of credentials, such as during hiring campaigns.
API (Application Programming Interface): A programmatic interface that allows software applications to interact with Turing Verify's verification engine, enabling automated document verification within existing workflows.
Webhook: An HTTP callback that sends real-time notifications when an event occurs. In document verification, webhooks notify integrated systems when a verification result is ready.
