摘要： A user log information output system includes a first user device configured to generate first user information by encrypting a unique identification (ID) of a first user according to a scheduled time; a first user server configured to generate first server information including a server group code of a hierarchical server group; a second user device configured to receive real-time token information through communication with the first user device, the real-time token information being generated based on the first user information and the first server information; and a second user server configured to generate proximity log information regarding the first user by reading the first user information and the first server information of the real-time token information received from the real-time token information from the second user device.
