TLDR: Identity Document Verification (IDV) reports flag issues like Visual Authenticity, Image Integrity, Data Comparison, and Police Record checks. Flags include poor image quality, document distortions (e.g., liquid scanning), data inconsistencies, and compromised documents. Liquid scanning distorts pixels, hindering fraud assessment. The report helps verify document authenticity and detect fraud risks.

Identity Document Verification (IDV) Reports

Here is a breakdown of the most common flags on an Identity Document Verification check report:

Flag Category & Sub-category	Reason for flag
Visual Authenticity	Checks the authenticity of the document in line with its security features and fonts.
Original Document Present	Flags when the original document is not present in the uploaded file. If a scanned image of a document has been submitted 'Original Document Present' will show as consider. This is expected.
Other	Secondary flag - This will be raised if any other flag occurs under ‘Visual Authenticity’.
Image Integrity	This result indicates that the image uploaded was not of sufficient quality to make a confident fraud assessment of the document.
Conclusive Document Quality	Documents can flag under this section when we have picked up on abnormal document features or obscured data points/security features that hinder our ability to make a confident fraud assessment. This section will flag if the file uploaded: Is a black and white scan Is distorted by liquid scanning* Is distorted by glare, blur or fingers in a photograph If the wet signature is not signed on a passport Is a fraudulent document
Data Comparison	Compares the name and D.O.B. on your client's document against the information submitted on our portal.
Data Consistency	Confirms the data on the MRZ is consistent with corresponding document data. Only performed on Passports and ID documents containing an MRZ.
Data Validation	Validates that the document information appears in the expected format. Typically expired ID documents will fail this check
Police Record	Indicates whether the document has been reported as lost, stolen or compromised on the Amber Hill UK police database.
Compromised Document	Cross-references the document with online sources to ensure the document image is not available on the internet.

Liquid Scanning

Some scanners have a feature that aims to improve the clarity of the document they scan by 'smoothing' or distorting pixels. Unfortunately, this impedes the ability to make an accurate fraud assessment of the document. This can also happen if the camera is set to ‘Portrait mode’.
