Abstract

An information device includes a reader, and a data processor. The reader reads, from a removable medium, ticket data that is provided from a server upon successful authentication, and that includes information representing a content of data processing to be executable upon the successful authentication. The data processor executes the data processing represented in the ticket data.

Claims

1. An information device comprising:

a reader that reads, from a removable medium, ticket data provided from a server upon successful authentication, the ticket data including information representing a content of data processing to be executable upon the successful authentication; and

a data processor that executes the data processing represented in the ticket data.

2. The information device according to claim 1, wherein

the ticket data further includes information representing a number of times within which data processing is permitted or a period during which data processing is permitted, and

the data processor executes the data processing represented in the ticket data within the number of times or during the period.

3. The information device according to claim 1, further comprising an output unit that stores, into the removable medium, first identification information of the information device,

wherein

the ticket data further includes second identification information set by the server based on the first identification information stored in the removable medium, and

the data processor executes, when the second identification information included in the ticket data matches with the first identification information, the data processing represented in the ticket data.

4. The information device according to claim 2, further comprising an output unit that stores, into the removable medium, first identification information of the information device and additional data having a value that differs depending on a timing,

wherein

the ticket data further includes the additional data and second identification information set by the server based on the first identification information and the additional data stored in the removable medium,

the ticket data includes first ticket data, and second ticket data that differs from the first ticket data,

the additional data includes first additional data, and second additional data that differs from the first additional data,

the data processor

executes, when the second identification information included in the ticket data matches with the first identification information, the data processing represented in the ticket data,

links, when data processing based on the first ticket data is executed, information regarding a number of times of the data processing to the first additional data included in the first ticket data, and records the information, and

links, when data processing based on the second ticket data is executed, information regarding a number of times of the data processing to the second additional data included in the second ticket data, and records the information.

5. The information device according to claim 2, further comprising an output unit that stores first identification information of the information device into the removable medium and into a predetermined storage unit, and stores second identification information of the information device that differs from the first identification information into the removable medium and into the predetermined storage unit, wherein the first identification information is decided to a first random value and the second identification information is decided to a second random value,

wherein

the ticket data further includes third identification information set by the server based on the first identification information stored in the removable medium, and fourth identification information set by the server based on the second identification information stored in the removable medium,

the ticket data includes first ticket data and second ticket data that differs from the first ticket data,

the data processor executes, when the first identification information included in the first ticket data matches with the third identification information stored in the storage unit, data processing represented in the first ticket data, and executes, when the second identification information included in the second ticket data matches with the fourth identification information stored in the storage unit, data processing represented in the second ticket data, and

the data processor links, when the data processing based on the first ticket data is executed, information regarding a number of times of the data processing to the first identification information included in the first ticket data, and records the information, and links, when the data processing based on the second ticket data is executed, information regarding a number of times of the data processing to the second identification information included in the second ticket data, and records the information.

6. The information device according to claim 1, further comprising a storage unit,

wherein

the ticket data includes identification information of the ticket data itself for identifying from other ticket data, and illicit ticket information of illicit ticket data,

the storage unit stores the illicit ticket information included in the ticket data, and

the data processor restricts when the identification information of the ticket data itself read by the reader corresponds to the illicit ticket information stored in the storage unit, execution of the data processing represented in the ticket data.

7. The information device according to claim 1, wherein

the server acquires identification information of the removable medium and sets the identification information in the ticket data,

the reader reads the identification information of the removable medium from the removable medium separately from the ticket data, and

the data processor executes, when the identification information included in the ticket data matches with the identification information of the removable medium, the data processing represented in the ticket data.

8. The information device according to claim 1, wherein

the ticket data further includes information representing an area where data processing is to be executed, and

the data processor executes, when the area represented the information included in the ticket data satisfies a predetermined condition, the data processing represented in the ticket data.

9. A data processing system comprising:

an information device capable of reading data from a removable medium; and

a server,

wherein the server includes an authentication unit that authenticates a user, and an output unit that stores, when the authentication unit has authenticated the user successfully, ticket data including information representing a content of data processing specified by the user, into the removable medium, and

the information device includes a reader that reads the ticket data from the removable medium, and a data processor that executes data processing represented in the ticket data.

10. A data processing method executed by an information device, the data processing method comprising:

reading, from a removable medium, ticket data provided from a server upon successful authentication, the ticket data including information representing a content of data processing to be executable upon the successful authentication, and

executing the data processing represented in the read ticket data

11. A non-transitory storage medium containing a program for causing an information device that is a computer to execute the data processing method according to claim 10.
