摘要： In an instant messaging device, a selection is received from a user, where the selection specifying a plurality of contacts to participate in an instant messaging session. At least one attribute type corresponding to the at least one intended recipient is retrieved in response to detecting a trigger event relating to a message intended for at least one recipient among the plurality of contacts. A verification operation is retrieved for each of the retrieved at least one attribute type. At least one retrieved verification operations is executed. The message is sent to the at least one intended recipient in response to successful execution of the at least one of the retrieved verification operations.

摘要： A computing device captures a live video of a user. For a first frame of the live video, the computing device obtains first target positional coordinates of a first target point located a first predetermined distance from the computing device and obtains first background data. For a second frame, the computing device obtains second target positional coordinates of a second target point located a second predetermined distance from the computing device and obtains second background data. The computing device calculates a target motion vector based on the first target point and the second target point and calculates a background motion vector based on feature points in the first background data and the second background data. The computing device determines a difference value between the target motion vector and the background motion vector and determines whether the user is spoofing the computing device based on the difference value.
