Verification that an authenticated user is in physical possession of a client device

A tangible computer readable medium useful in association with a computer that includes one or more processors and a memory, the computer readable medium including computer instructions that are configured to cause the computer, by execution of the computer instructions in the one or more processors from the memory, to determine that a person is in physical possession of a remotely located device by at least:

• monitoring the remotely located device for gesture-induced data associated with physical manipulation of at least one user input device of the remotely located device;
• causing the remotely located device to record buffer data representing one or more events of the user input device;
• causing the remotely located device to record user-generated data received from the user input device;
• determining whether the buffer data indicates that the user-generated data is generated in response to physical manipulation by the user;
• and
• determining that the user is in physical possession of the remotely located device upon determining that the buffer data indicates that the at least some of the events of the user input device are generated in response to physical manipulation by the user.

A computer system comprising:

• at least one processor;
• a computer readable medium that is operatively coupled to the processor;
• network access circuitry that is operatively coupled to the processor;
• and
• authentication logic (i) that executes at least in part in the processor from the computer readable medium and (ii) that, when executed, causes the processor to determine that a person is in physical possession of a remotely located device by at least:
• monitoring the remotely located device for gesture-induced data associated with physical manipulation of at least one user input device of the remotely located device;
• causing the remotely located device to record buffer data representing one or more events of the user input device;
• causing the remotely located device to record user-generated data received from the user input device;
• determining whether the buffer data indicates that the user-generated data is generated in response to physical manipulation by the user;
• and
• determining that the user is in physical possession of the remotely located device upon determining that the buffer data indicates that the at least some of the events of the user input device are generated in response to physical manipulation by the user.
