Abstract

An information processing system includes a certification authority server, a web server, and a terminal. The certification authority server includes a processor, and a memory storing program instructions that cause the processor to receive an issuance request for a certificate transmitted from the web server, verify whether an operator of the web server has a right to use a trademark identified on the basis of information included in the issuance request, and transmit a certificate including the trademark to the web server when the operator has the right. The web server includes a processor, and a memory storing program instructions that cause the processor to transmit the certificate to the terminal in response to access from the terminal. The terminal includes a processor, and a memory storing program instructions that cause the processor to display the trademark included in the certificate. This improves reliability of the certificate including the trademark.

Claims (42)

1. An information processing system comprising:

a certification authority server;

a web server; and

a terminal,

wherein

the certification authority server includes:

a processor; and

a memory storing program instructions that cause the processor to:

receive an issuance request for a certificate transmitted from the web server,

verify whether an operator of the web server has a right to use a trademark identified on a basis of information included in the issuance request, and

to transmit a certificate including the trademark to the web server when the operator has the right,

the web server includes:

a processor; and

a memory storing program instructions that cause the processor to:

transmit the certificate to the terminal in response to access from the terminal, and

the terminal includes:

a processor; and

a memory storing program instructions that cause the processor to:

display the trademark included in the certificate.

2. The information processing system according to claim 1 , wherein

the program instructions of the certification authority server cause the processor of the certification authority server to:

verify existence of the operator, and

transmit the certificate to the web server when, in addition, the existence is confirmed by the second verification unit.

3. An information processing method executed by a certification authority server, a web server, and a terminal, the method comprising:

executing, by the certification authority server,

receiving an issuance request for a certificate transmitted from the web server,

verifying whether an operator of the web server has a right to use a trademark identified on a basis of information included in the issuance request, and

transmitting a certificate including the trademark to the web server when the operator has the right;

executing, by the web server,

transmitting the certificate to the terminal in response to access from the terminal; and

executing, by the terminal,

displaying the trademark included in the certificate.

4. The information processing method according to claim 3 , further comprising

executing, by the certification authority server,

verifying existence of the operator,

wherein the certificate is transmitted to the web server in the first transmission procedure when, in addition, the existence is confirmed in the second verification procedure.

5. A non-transitory computer-readable storage medium that stores therein a program causing a computer to execute:

a reception procedure of receiving an issuance request for a certificate transmitted from a web server;

a first verification procedure of verifying whether an operator of the web server has a right to use a trademark identified on a basis of information included in the issuance request; and

a first transmission procedure of transmitting a certificate including the trademark to the web server when the operator has the right.

6. The non-transitory computer-readable storage medium according to claim 5 , further causing the computer to execute a second verification procedure of verifying existence of the operator,

wherein the certificate is transmitted to the web server in the first transmission procedure when, in addition, the existence is confirmed in the second verification procedure.
