Method and system for collaborating of physiological signal measure devices

A method and a system for collaborating bio-signal measure devices are provided to perform an exact private health management through mutual collaboration between bio-signal measure devices at a ubiquitous health care environment. A plurality of bio-signal measure devices(120) measures a bio-signal of user. A potable information terminal(100) includes a communication driver(102), a low-level feature extracting driver(104), and a high-level feature extracting driver(106). The communication driver receives a bio-signal data from a plurality of bio-signal measure devices. The low-level feature extracting driver calculates a low-level feature value from the bio-signal data. The high-level feature extracting driver calculates a high-level feature value from the low-level feature value. A service provider server(140) manages a health condition of user based on the bio-signal data and the feature value. A measure device provider server(150) provides information of the bio-signal measure device by a request of the portable information terminal.
