Program, Information Processing Device, Information Processing Method and Information Processing System
PROBLEM TO BE SOLVED: To establish a method which enables data indicating a specific state among many states to be promptly shared between users and between devices.SOLUTION: A state monitoring section 102 monitors whether or not designation of a specific state is continued in a user terminal 1-1 which accesses an information processing device using a first identifier. A second identifier generation section 103 generates a second identifier when access of the user terminal 1-1 using the first identifier is received by a reception section 101. A correspondence management section 104 manages a correspondence relation between the first identifier corresponding to the specific state and the generated second identifier during a period when the designation of the specific state is continued in the user terminal 1-1 or a predetermined time span after the period is completed, and abolishes the correspondence relation between the first identifier and the second identifier when termination of the designation of the specific state in the user terminal 1-1 or a lapse of predetermined period after the termination is monitored.
