| 摘要 |
A user instruction communicated over a communications network via a first communication channel to a relying entity for action, is confirmed by having a trusted entity receive verification information corresponding to the communicated user instruction from the user over the network via a second communication channel and/or verification information corresponding to a received user instruction from the relying entity via a third communication channel. If verification information is received from only the user, it is communicated to the relying entity. If from both, the trusted entity verifies the received user instruction based on the received verification information. If from only the relying entity, it is communicated to the user. |
