There are a number of ways to combine the scores you get for each part of the identity checking process. These combinations are known as identity profiles.
Meeting an identity profile is the only way to get one of the following levels of confidence in someone’s identity:
To meet an identity profile, your scores must be the same as, or higher than, the scores needed for each check. Do not add your scores up.
Example
You need a validity score of 1 to meet an identity profile. The evidence from the person whose identity you’re checking has a validity score of 2. You can use this score of 2 to meet the lower score requirements of the identity profile.
You do not need to do an activity history or identity fraud check to meet some identity profiles.
If a profile says an activity check is not needed, it’s usually because the organisation that issued the evidence has already checked the claimed identity exists.
You usually will not need to do an identity fraud check if the person going through the identity checking process has already been matched to the claimed identity through a physical or biometric comparison.
Choosing an identity profile
You can choose to meet any identity profile. Which one you choose depends on:
- how confident you need to be in someone’s identity
- what evidence your users are likely to have
- which parts of the identity checking process you can do
- how thoroughly you do each part of the identity checking process
- how many pieces of evidence you need
Collecting multiple pieces of evidence
You might need to collect multiple pieces of evidence if the evidence you already have does not:
- include all the personal information you need
- have many security features that stop it from being forged or counterfeit
You’ll also need to link these pieces of evidence together to make sure they all relate to the claimed identity.
Example
You need evidence of a person’s name and address. A person gives you a bus pass that shows their photo and address but not their name. They also give you a genuine passport that shows their photo and their name. You check these photos match, so you know both pieces of evidence relate to the same claimed identity.
If you collect more than one piece of evidence, you must make sure the evidence has been issued by either:
- different organisations
- an organisation that used a different identity checking process to issue each piece of evidence you’re using
Example
You collect 3 pieces of evidence of a claimed identity from different organisations. One is a letter from a local authority, one is from a solicitor and one is from a gas company. They were all issued to the same claimed identity.
