Privilege management system, method, and recording medium

A privilege management system comprising:

• an accepting section which accepts privilege coupon data indicative of a content of a privilege and a condition under which the privilege is granted, and a right data acquisition request including data which is used to judge whether the privilege is granted, from a requesting side of right data which releases a utilization restriction of a circulation content;
• a verifying section which judges whether the privilege is granted to the requesting side based on the privilege coupon data and the acquisition request;
• and
• a service section which grants the privilege to the requesting side based on the content of the privilege indicated by the privilege coupon data when it is determined that the privilege is granted,
• wherein the privilege coupon data includes a content condition ID which specifies a content as a privilege grant target,
• the acquisition request includes a contents ID indicative of the circulation content, and
• the verifying section determines that the privilege is granted to the requesting side when the content condition ID is consistent with the circulation content ID.

A privilege management system comprising:

• an accepting section which accepts privilege coupon data indicative of a content of a privilege and a condition under which the privilege is granted, and a right data acquisition request from a requesting side of right data which releases a utilization restriction of a circulation content;
• a verifying section which judges whether the privilege is granted to the requesting side based on the privilege coupon data and the acquisition request;
• and
• a service section which grants the privilege to the requesting side based on the content of the privilege indicated by the privilege coupon data when it is determined that the privilege is granted,
• wherein the privilege coupon data includes request number condition data which specifies a total number of requests which permit granting the privilege, and
• the verifying section determines that the privilege is granted to the requesting sides when a total number of the acquisition requests accepted by the accepting section is not less than the total number of requests.

A privilege management system comprising:

• an accepting section which accepts privilege coupon data indicative of a content of a privilege and a condition under which the privilege is granted, and a right data acquisition request including data which is used to judge whether the privilege is granted, from a requesting side of right data which releases a utilization restriction of a circulation content;
• a verifying section which judges whether the privilege is granted to the requesting side based on the privilege coupon data and the acquisition request;
• and
• a service section which grants the privilege to the requesting side based on the content of the privilege indicated by the privilege coupon data when it is determined that the privilege is granted,
• wherein the privilege coupon data includes a path condition ID which specifies a circulation path with which granting the privilege is permitted,
• the acquisition request includes a path ID indicative of a circulation path of the circulation content, and
• the verifying section determines that the privilege is granted to the requesting side when the path condition ID is consistent with the path ID.

A privilege management system comprising:

• an accepting section which accepts privilege coupon data indicative of a content of a privilege and a condition under which the privilege is granted, and a right data acquisition request from a requesting side of right data which releases a utilization restriction of a circulation content;
• a verifying section which judges whether the privilege is granted to the requesting side based on the privilege coupon data and the acquisition request;
• and
• a service section which grants the privilege to the requesting side based on the content of the privilege indicated by the privilege coupon data when it is determined that the privilege is granted,
• wherein the privilege coupon data includes time condition data which specifies a time in which granting the privilege is permitted, and
• the verifying section determines that the privilege is granted to the requesting side when a time at which the acquisition request is accepted is within a time indicated by the time condition data.

A privilege management system comprising:

• an accepting section which accepts privilege coupon data indicative of a content of a privilege and a condition under which the privilege is granted, and a right data acquisition request from a requesting side of right data which releases a utilization restriction of a circulation content,
• a verifying section which judges whether the privilege is granted to the requesting side based on the privilege coupon data and the acquisition request;
• and
• a service section which grants the privilege to the requesting side based on the content of the privilege indicated by the privilege coupon data when it is determined that the privilege is granted,
• wherein the privilege coupon data is subjected to preprocessing in order to detect an interpolation,
• the verifying section checks whether the privilege coupon data is interpolated, and
• the service section grants the privilege to the requesting side when the privilege coupon data is not interpolated.

A method of granting a privilege to a requesting side of right data which releases a utilization restriction of a circulation content by a computer,

• the method comprising:
• accepting from the requesting side privilege coupon data indicative of a content of the privilege and a condition under which the privilege is granted, and a right data acquisition request including data which is used to judge whether the privilege is granted;
• judging whether the privilege is granted to the requesting side based on the privilege coupon data and the acquisition request;
• and
• executing a service which grants the privilege to the requesting side based on the content of the privilege indicated by the privilege coupon data when it is determined that the privilege is granted,
• wherein the privilege coupon data includes a permitting side condition ID which specifies a utilization permitting side which permits granting the privilege,
• the acquisition request includes a utilizing side ID indicative of a utilizing side of the right data, and
• the service is executed when the permitting side condition ID is consistent with the utilizing side ID.

A computer-readable recording medium having a program recorded therein,

• the program allowing the computer to function as:
• an accepting section which accepts privilege coupon data indicative of a content of a privilege and a condition under which the privilege is granted, and a right data acquisition request including data which is used to judge whether the privilege is granted, from a requesting side of right data which releases a utilization restriction of a circulation content;
• a verifying section which judges whether the privilege is granted to the requesting side based on the privilege coupon data and the acquisition request;
• and
• a service section which grants the privilege to the requesting side based on the content of the privilege indicated by the privilege coupon data when it is determined that the privilege is granted,
• wherein the privilege coupon data includes a permitting side condition ID which specifies a utilization permitting side which permits granting the privilege,
• the acquisition request includes a utilizing side ID indicative of a right data utilizing side, and
• the verifying section determines that the privilege is granted to the requesting side when the permitting side condition ID is consistent with the utilizing side ID.
