There are multiple ways that an individual can be verified, for instance through fingerprints or through a digital signature. Companies who use attestation services must follow certain rules such as having their own attestation service or only accepting attestation from other companies they trust and having no control over the procedure Attestation services make sure that all the available information about a particular person can be found at one place so that people can easily identify themselves in order for verification processes to take place.
