Method for matching multiple devices, and device and server system for enabling matching

A device comprising:

• a sensing element;
• a memory;
• a processor;
• and
• program circuitry including computer readable instructions which, when executed by the processor, cause the program circuitry to determine, on the basis of a value regarding biological information of a user of the device, first characteristic information on a biological state of the user,
• wherein the value is obtained by the sensing element, and the device is matched with an external device on the basis of the first characteristic information and second characteristic information, which is independently determined by the external device based on data related to the biological state of the user, associated with or generated according to the biological state of the user,
• wherein matching the device with the external device comprises at least one of indicating that the device and the external device belong to the user, indicating that the device and the external device function for the sake of the user, indicating that the device and the external device are located substantially close to each other, or indicating that one of the device and the external device is competent to authenticate or permit the other of the device and the external device.

A server system for matching, comprising:

• a processor;
• a communication unit configured to communicate with a first device and a second device;
• a matching unit including computer readable instructions which, when executed by the processor, cause the matching unit to match the first device with the second device on the basis of first characteristic information on a biological state of a user from the first device and second characteristic information associated with or generated according to the biological state of the user from the second device;
• and
• a storage for storing information provided from at least one of the first device and the second device,
• wherein the first characteristic information is determined by the first device based on a pattern of values related to the biological state of the user, and the values are obtained by a sensing element of the first device, and wherein the second characteristic information determined by the second device based on data related to the biological state of the user, and the data is obtained by a sensing element of the second device,
• wherein matching the first device with the second device comprises at least one of indicating that the first device and the second device belong to the user, indicating that the first device and the second device function for the sake of the user, indicating that the first device and the second device are located substantially close to each other, or indicating that one of the first device and the second device is competent to authenticate or permit the other of the first device and the second device.
