The problem of giving and maintaining a continuing identity for a real-world person on a digital network.
- Simplest of all the User needs to Authenticate from time to time and on a variety of devices under less than ideal conditions where passwords are mistyped and Alternate Authentication factors are lost or fail.
- More severe Recovery problems occur when the User has lost control of their account and needs it to be reset. The level of Authentication for these situation can be severely taxing to a user desperate for access to their accounts.
- When an Authentication factor like an alternate email or phone number is compromised, insecure Recovery methods themselves become a means of attack, especially since factors like phone number were never intended to be secure.
- Before the user can request a list of data that is held about them, or Redress for mistakes made by a Data Controller they must Authenticate themselves to the data controller to assure that the Recovery process itself does not leak data.
- Before any Data Controller can report to the user about leakage of User Private Information, they just have good contact information for the User.
- Before any Data Controller can allow access methods or factors to be changed on an account, they must be assured that this is not an attack.
- Recovery is a fertile place for attackers to take over user's accounts, particularly when a low security second factor, like SMS, is used for recovery.
- If the account the attacker subverts is an OpenID Provider (OP or IAP), the attacker can then move onto any Open ID Clients (RPs) that subscribe to that OP.
- As a part of creating a User Object to hold User Information any Site needs to first of all assure that they can contact the user.
- The two most common contact methods are email address and Smart Phone numbers. But such contact itself can become the vector for attack so any contact email must be recognizable and protected against spoofing by attackers.
