Abstract: A P2P transmission method having enhanced security, according to an embodiment of the present invention, comprises: a step for receiving by a server from a first client a first temporary key issuance request; a step for generating a comparison key; a step for receiving an input key from a second client; a step for receiving from a transmission client a transmission request for a particular file; a step for comparing the comparison key and the input key; a transmission path selecting step for selecting a particular transmission path between the transmission client and a reception client if the comparison key and the input key correspond to each other; and a file transmission requesting step for requesting file transmission, through the selected transmission path, from the transmission client and reception client.

Abstract: The present disclosure relates to a program, a method and a system for P2P transmission. A method for P2P transmission by means of an access point, according to an embodiment of the present disclosure, includes at least: a step for receiving identification information of a detected access point from a transmission client and a reception client; a step for, if the reception client detects a first access point as the same detected access point or accesses the first access point which is the same detected access point, configuring the first access point as a transmission path; a step for checking whether or not the first access point has been configured to be blocked; and a step for matching first identification information with whether or not the first access point has been configured to be blocked and storing same in an accumulation database.
