Abstract: A remote assistance controller serves as an intermediary between a user requesting remote assistance and a remote assistor. A remote assistance policy determines what the remote assistor can see or not see on the requestor's computer system, and may additionally determine allowed or disallowed actions by the remote assistor. The remote assistance policy may be defined by the requesting user, or can be a default policy for the remote assistance controller. The remote assistance controller generates views for the requestor and for the remote assistor. When the remote assistor requests an operation on the requestor's computer system, the remote assistance controller checks the remote assistance policy to determine whether the remote assistor is allowed to perform the requested operation. When the requested operation is allowed according to the remote assistance policy, the remote assistance controller allows the requested operation, and refreshes the views for the requestor and the remote assistor.

A risk factor corresponding to a risk control decision result of a service that matches service data for a corresponding risk factor is determined. The risk factors are associated with risk control rules and a risk control model identifying relationships between risk factors and risk control decision results. A risk information set corresponding to the risk factor is determined that includes levels of risk information having different refinement degrees and including information explaining a cause of the risk control decision result. The levels of risk information are determined from the levels of risk information based on a risk information requirement level of a service owner of the service. The levels of risk information have refinement degrees matching the risk information requirement level of the service owner. The levels of risk information are provided to the service owner.
