Signature verification between a mobile device and a computing device

A non-transitory computer readable storage medium having stored therein instructions, which when executed by a computing device, cause the computing device to:

• receive, at a receiving electrode of a first touch panel, a signal from a transmitting electrode of a second touch panel of a mobile device;
• receive, at a processing circuit, the signal from the receiving electrode of the first touch panel;
• generate, at the processing circuit, received data according to the signal;
• determine, at a processor, whether the received data corresponds to a signature stored in a memory;
• and
• generate, at the processor, an authentication signal when determining that the received data corresponds to the signature stored in the memory.

A mobile device, comprising:

• a first touch panel with a transmitting electrode, wherein the transmitting electrode is configured to transmit a signal to a receiving electrode of a second touch panel of a computing device;
• and
• a processing circuit, configured to provide the signal to the transmitting electrode,
• wherein, when the signal corresponds to a signature stored in the computing device, the mobile device performs further operation with the computing device.

A computing device, comprising:

• a memory;
• a first touch panel with a receiving electrode, wherein the receiving electrode is configured to receive a signal from a transmitting electrode of a second touch panel of a mobile device;
• a processing circuit, configured to receive the signal from the receiving electrode and generate received data according to the signal;
• and
• a processor, determining whether the received data corresponds to a signature stored in the memory, and generating an authentication signal when determining that the received data corresponds to the signature.
