Introduction to risk types

IdNetwork supports 2 types of major risk detection:

IDFAKE (identity fraud)
DUPLICATE (duplicate authentication)
BATCH_REGISTER (Batch register)

The risk and sub-risk type details are shown in the table below:

Risk type	Risk description	Sub-risk type	Sub-risk description
IDFAKE	Tampering with document information i.e. face image, numbers, name and other information.	SameFaceDifferentIdNumber	Same face, different ID numbers (same ID type).
		SameFaceDifferentPerson	Same face, different name and date-of-birth.
		SameIdDifferentFace	Same ID number (same ID type), different faces.
		SameIdDifferentPerson	Same ID number (same ID type), different name and date-of-birth.
		SamePersonDifferentFace	Same name and date-of-birth, different faces.
		SamePersonDifferentIdNumber	Same name and date-of-birth, different document numbers (same ID type).
DUPLICATE	Multiple documents for the same person.	SameFaceDifferentIdType	Same face, different ID types.
DUPLICATE	Multiple documents for the same person.	SameFaceDifferentUserId	Same face, different users.
BATCH_REGISTER	Different persons conducting verification under the same background.	SameFaceBackgroundDifferentFace	Highly similar face background, different faces.
