SERVER FOR CONTROLLING AN INFORMATION SHARING STATE BETWEEN A FIRST MOBILE PHONE AND A SECOND MOBILE PHONE VIA A NETWORK
First Claim
1. A server for controlling an information sharing state between a first mobile phone and a second mobile phone via a network, the server comprising:
- a network interface configured to communicate, via the network, with the first mobile phone and the second mobile phone;
a memory configured to store a predetermined distance data indicating a predetermined distance; and
circuitry configured toreceive, via the network interface, a first Global Positioning System (GPS) signal indicating a current location of the first mobile phone, first user information indicating user information of a first user, and first restriction information indicating restriction information of the first user from the first mobile phone, the first GPS signal being obtained by the first mobile phone using a GPS receiver in the first mobile phone;
receive, via the network interface, a second GPS signal indicating a current location of the second mobile phone, second user information indicating user information of a second user, and second restriction information indicating restriction information of the second user from the second mobile phone, the second GPS signal being obtained by the second mobile phone using a GPS receiver in the second mobile phone;
calculate a distance between the current location of the first mobile phone and the current location of the second mobile phone based on the received first GPS signal and the received second GPS signal;
compare the calculated distance with the predetermined distance indicated by the predetermined distance data stored in the memory;
change an information sharing state between the first mobile phone and the second mobile phone via the network from a first state in which information sharing via the network between the first mobile phone and the second mobile phone is disabled to a second state in which the information sharing is enabled based on a comparison result obtained by the comparison; and
restrict the change of the information sharing state from the first state to the second state based on the first restriction information of the first mobile phone and the second user information of the second mobile phone.
