Compare User Information

Partners are able to automatically compare the information returned by an ID authority with the information we read from a user-submitted document, such as a passport.
This comparison is sequence-agnostic: partners can combine Enhanced KYC or Biometric KYC and Document Verification in any order they choose.
By calling our compare_user_info endpoint, partners need not rely on human review, and can have an extra assurance that their user’s KYC information checks out.

Evaluating the Response
If all the underlying fields are an exact match the overall result is an exact match. If at least one of the underlying fields is an exact match, partial match, or transposed then the overall result is a partial match. If all of the fields are no match then the entire result is no match. Here is an explanation of the matching rules:
Exact Match
The values are a case-insensitive exact match
Partial Match
For name values it is a partial match if the values are a levenshtein distance of <= 2 apart.
 
For date of birth and expiration date it is a partial match if any single component (Day, Month, Year) is within 1 digit of the returned value. If more than one component of date birth is off then it is no match.
Transposed
Two elements are transposed.
 
For example first name and last name or month of birth and date of birth
No Match
All other cases
We advise that you build a business logic that handles jobs that have an overall result of partial match
