    摘要： A wireless positioning server using clock offset compensation and a wireless positioning method using the same. The wireless positioning server using clock offset compensation estimates a precise position of a tag requiring position information by effectively predicting information regarding a distance between a beacon for performing positioning and the tag requiring position information. An error in the positioning estimation result due to a clock offset is minimized by measuring a relative clock frequency ratio between beacons and by compensating for clock frequencies of the beacons when a distance between a beacon and a tag is estimated.

    摘要： A user terminal includes a pairing circuit, a communication circuit, and a control circuit. The pairing circuit receives a normal code of an application from an application providing server in a process of downloading and installing the application from the application providing server, and performs a pairing operation with a peripheral device that stores a core code of the application received from the application providing server. The communication circuit, in a process of executing the application, transmits distinct information of the user terminal to the peripheral device to make the peripheral device encrypt the core code and decrypt the encrypted core code. The control circuit transmits an execution request message to the peripheral device, and receives an execution result of the core code from the peripheral device.
