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

a data processor that

executes the executable content represented in the ticket data, and

stores, in 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

information representing a number of times that the executable content is permitted to be executed or a period during which the executable content is permitted to be executed,

the additional data and second identification information set by the server based on the first identification information, and

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

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

wherein the data processor

executes the executable content within the number of times that the executable content is permitted to be executed or within the period during which the executable content is permitted to be executed, when the second identification information included in the ticket data matches the first identification information,

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

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

2. The information device according to claim 1, wherein the data processor stores third identification information of the information device in the removable medium and in a memory storage, and stores fourth identification information of the information device that differs from the third identification information in the removable medium and in the memory storage,

wherein the third identification information is decided to a first random value and the fourth identification information is decided to a random value,

wherein

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

the ticket data includes third ticket data and fourth ticket data that differs from the third ticket data,

the data processor executes, when the third identification information included in the third ticket data matches the fifth identification information stored in the memory storage, executable content represented in the third ticket data, and executes, when the fourth identification information included in the fourth ticket data matches the sixth identification information stored in the memory storage, executable content represented in the fourth ticket data, and

the data processor links, when the executable content based on the third ticket data is executed, third information regarding a number of times of the executable content is executed to the third identification information included in the third ticket data, and records the third information, and links, when the executable content based on the fourth ticket data is executed, fourth information regarding a number of times of the executable content is executed to the fourth identification information included in the fourth ticket data, and records the fourth information.

3. The information device according to claim 1, further comprising a memory storage,

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 memory storage 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 memory storage, execution of the executable content represented in the ticket data.

4. 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 the identification information of the removable medium, the executable content represented in the ticket data.

5. The information device according to claim 1, wherein

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

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

6. A data processing system comprising:

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

a server,

wherein the server includes a processor that authenticates a user, and stores in the removable medium, when the the user is successfully authenticated, ticket data including information representing an executable content specified by the user, and

the information device includes

a reader that reads the ticket data from the removable medium, the ticket data being provided from the server upon successful authentication, and

a data processor that executes the executable content represented in the ticket data, and stores, in 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

information representing a number of times that the executable content is permitted to be executed or a period during which the executable content is permitted to be executed,

the additional data and second identification information set by the server based on the first identification information, and

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

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

wherein the data processor

executes the executable content within the number of times that the executable content is permitted to be executed or within the period during which the executable content is permitted to be executed, when the second identification information included in the ticket data matches the first identification information,

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

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

7. 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, the ticket data being provided from the server upon successful authentication, and the ticket data including information representing an executable content that is to be executable upon the successful authentication, and

executing the executable content represented in the read ticket data, and

storing, in 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

information representing a number of times that the executable content is permitted to be executed or a period during which the executable content is permitted to be executed,
