Online identification verification services work by scanning a user's photo ID, photographing the faces, and checking that the ID is legitimate and matches the face. Most services can use a computer web cam or phone camera. Many of the services require some additional verification. For example, MyVerifiedID also verifies the user's email and phone number.
These services use various pattern recognition technologies to compare a scanned ID against known formats, such as government issued driver's licenses and passports. Simultaneously the services may capture the written information including name and birth date to check against information provided by the user. Additionally, they use face recognition technology in order to match the photo on the ID against the photo taken during verification.
While most online ID verification services focus on technological verification, some offer manual ID examination by experts. For example, IDChecker has experts ready to verify scanned identification according to border control standards.
Nearly all such services include encrypted data transmission and storage to protect users' personal information. However, some services, including MyVerifiedID, actually don't store user information at all. Everything is deleted as soon as the verification process is complete.
These services are intended to increase trust in online transactions; however, so far reviews of these services suggest that users do not fully trust online ID verification yet.
