US Patent 9882914 Security group authentication

A system for security group authentication comprises an interface, an authentication level determiner, and an authenticator. The interface is for receiving a request from a user to perform an action. The authentication level determiner is for determining that a current authentication level for the user is not adequate for the action. The authenticator is for providing a request to authenticate a new authentication level to the user. The current authentication level and the new authentication level are associated with the user using a security group.
