Level of Assurance
ProSale services can be used with different levels of assurance. When the signatories are added you also enter the level of assurance that is required for their identification. ProSale Signing provides a number of well-known ways of identifying a signatory, which also can be combined in order to increase the security.
Assurance is categorized in different levels:
Level 1: Little or no confidence in the asserted identity’s validity.
Level 2: Some confidence in the asserted identity’s validity.
Level 3: High confidence in the asserted identity’s validity.
Level 4: Very high confidence in the asserted identity’s validity.
Different situations can require different levels of assurance. In some cases levels 1 and 2 is sufficient, but in others level 3 is required. One reason for this can be legal requirements such as Consumer Protection Acts.
