Abstract

A connection server is a connection system that is able to perform communication with a plurality of user side terminals and establishes a connection between the user side terminals, and includes a passcode generator that generates and transmits a passcode to the user side terminal, a passcode storage unit that stores a passcode in association with the user side terminal, a passcode receiving unit that receives a transmission passcode from the user side terminal, a passcode authentication unit that determines whether there is a stored combination of passcodes that matches a combination of a generated passcode and a received transmission passcode, and a connection unit that establishes a connection between the user side terminals in response to the determination.

Claims

1. A connection system that is able to perform communication with a plurality of terminals and establishes a connection between the terminals, the connection system comprising:

passcode generation means for generating and transmitting a first passcode to a first terminal;

passcode storage means for storing therein a first passcode generated by the passcode generation means in association with the first terminal;

passcode reception means for receiving a first transmission passcode from a second terminal;

passcode authentication means for determining whether there is a first passcode that matches a first transmission passcode received by the passcode reception means and is stored by the passcode storage means; and

connection means for establishing a connection between the first terminal and the second terminal, wherein

the passcode generation means, when it is determined by the passcode authentication means that there is a matching first passcode, generates and transmits a second passcode that follows the first passcode to the second terminal,

the passcode storage means stores therein a combination of the first passcode, and a second passcode generated by the passcode generation means, in association with the second terminal,

the passcode reception means receives a second transmission passcode from the first terminal,

the passcode authentication means determines whether there is a combination that matches a combination of a first passcode generated by the passcode generation means and a second transmission passcode received by the passcode reception means and is stored by the passcode storage means, and

the connection means, when it is determined by the passcode authentication means that there is a matching combination, establishes a connection between a first terminal that is a transmission source of the second transmission passcode and a second terminal stored by the passcode storage means in association with the matching combination.

2. The connection system according to claim 1, wherein the passcode generation means generates the second passcode, when it is determined by the passcode authentication means that there is a matching first passcode, and when the matching first passcode is stored in duplication in the passcode storage means.

3. The connection system according to claim 1, wherein

the passcode generation means, when it is determined by the passcode authentication means that there is a matching combination, generates a new second passcode that follows a second passcode used for the determination,

the passcode authentication means performs determination using the new second passcode generated by the passcode generation means, and

the connection means, when it is determined a certain number of times by the passcode authentication means that there is a matching combination, establishes a connection between the first terminal and the second terminal.

4. The connection system according to claim 3, wherein the connection means, when it is determined a set number of times by the passcode authentication means that there is a matching combination, establishes a connection between the first terminal and the second terminal.

5. The connection system according to claim 1, wherein the passcode generation means determines number of digits of a passcode to generate in accordance with a passcode stored by the passcode storage means.

6. The connection system according to claim 1, wherein the passcode generation means generates a passcode in accordance with a passcode stored by the passcode storage means.

7. The connection system according to claim 6, wherein the passcode generation means generates a passcode in accordance with also a time that a passcode stored by the passcode storage means is generated.

8. The connection system according to claim 1, wherein

the passcode generation means accepts a request from the first terminal and generates a first passcode, and

the passcode authentication means determines matching in accordance with whether a transmission source of a transmission passcode is a terminal that made the request.

9. The connection system according to claim 1, wherein the connection means, when it is determined by the passcode authentication means that there is a matching combination, transmits a passcode for confirmation to a first terminal that is a transmission source of the second transmission passcode and to a second terminal stored by the passcode storage means in association with the matching combination and, when information that a connection is approved is received from the first terminal and the second terminal in response to the transmission, establishes a connection between the first terminal and the second terminal.

10. A connection method that is an operation method of a connection system being able to perform communication with a plurality of terminals and establishing a connection between the terminals, the connection method comprising:

a passcode generation step of generating and transmitting a first passcode to a first terminal;

a passcode storage step of storing a first passcode generated at the passcode generation step in association with the first terminal;

a passcode reception step of receiving a first transmission passcode from a second terminal;

a passcode authentication step of determining whether there is a first passcode that matches a first transmission passcode received at the passcode reception step and is stored at the passcode storage step; and

a connection step of establishing a connection between the first terminal and the second terminal, wherein

at the passcode generation step, when it is determined at the passcode authentication step that there is a matching first passcode, a second passcode that follows the first passcode is generated and transmitted to the second terminal,

at the passcode storage step, a combination of the first passcode, and a second passcode generated at the passcode generation step is stored in association with the second terminal,

at the passcode reception step, a second transmission passcode is received from the first terminal,

at the passcode authentication step, whether there is a combination that matches a combination of a first passcode generated at the passcode generation step and a second transmission passcode received at the passcode reception step and is stored at the passcode storage step is determined, and

at the connection step, when it is determined at the passcode authentication step that there is a matching combination, a connection is established between a first terminal that is a transmission source of the second transmission passcode and a second terminal stored at the passcode storage step in association with the matching combination.
