Abstract

A data conversion method performed by a computer, the method is configured to cause the computer to; when the computer receives a plurality of data, acquire first information and second information from a storage, the first information designating any data among the plurality of data, the second information designating a predetermined number of data, data formats of which are collectively converted among the plurality of data; acquire, based on the acquired first information and the acquired second information, the predetermined number of conversion target data from the received plurality of data; extract each pieces of specific information embedded in each of the acquired predetermined number of conversion target data; and convert the data format of each of the respective predetermined number of conversion target data by using the extracted predetermined number of pieces of the specific information.

Claims

1. A computer-readable non-transitory storage medium storing a data conversion program that causes a computer to execute a process, the process comprising:

when receiving a plurality of data, acquiring first information and second information from a storage, the first information designating any data among the plurality of data, the second information designating a predetermined number of data, data formats of which are collectively converted, among the plurality of data;

acquiring, based on the acquired first information and the acquired second information, the predetermined number of conversion target data from the received plurality of data;

extracting a predetermined number of pieces of specific information embedded in each of the acquired predetermined number of conversion target data; and

converting a data format of each of the predetermined number of conversion target data by using the extracted predetermined number of pieces of the specific information.

2. The computer-readable storage medium storing the data conversion program according to claim 1, the process further comprising:

receiving the first information and the second information in advance, from an information processing device that transmits the plurality of data, before the acquiring the first information and the second information; and

storing the received first information and the received second information in the storage.

3. The computer-readable storage medium storing the data conversion program according to claim 2, wherein

the first information is information indicating that the plurality of data are designated in descending order of times respectively corresponding to the respective data.

4. The computer-readable storage medium storing the data conversion program according to claim 3, wherein

the times corresponding to the respective data are times when the information processing device has acquired the respective data.

5. The computer-readable storage medium storing the data conversion program according to claim 2, the process further comprising:

receiving, before the acquiring the first information and the second information, from the information processing device that transmits the plurality of data, position information designating positions where the specific information is embedded in each of the predetermined number of data; and

storing the received position information in the storing section,

and wherein

in the extracting the predetermined number of pieces of the specific information, the position information is acquired from the storage, and the respective predetermined number of pieces of the specific information are extracted from the positions indicated by the position information in the respective predetermined number of conversion target data.

6. The computer-readable storage medium storing the data conversion program according to claim 1, wherein

in the converting the data formats, a specific value, which is a sum of respective values indicated by the extracted predetermined number of pieces of the specific information, is calculated, and the data formats of the acquired plurality of data are converted by respectively performing a predetermined operation using respective values indicated by the acquired predetermined number of conversion target data and the specific value.

7. The computer-readable storage medium storing the data conversion program according to claim 6, wherein

the predetermined operation is addition or subtraction.

8. The computer-readable storage medium storing the data conversion program according to claim 1, wherein

in the acquiring the first information and the second information, an information processing device that has transmitted the plurality of data is specified, and the first information and the second information corresponding to the specified information processing device are acquired.

9. The computer-readable storage medium storing the data conversion program according to claim 1, wherein

the acquiring the predetermined number of conversion target data, the extracting the predetermined number of pieces of the specific information, and the converting are repeatedly performed until the data formats are converted for all of the received plurality of data.

10. A computer-readable non-transitory storage medium storing a data conversion program that causes a computer to execute a process, the process comprising:

acquiring first information and second information from a storage, the first information designating any data among a plurality of data, the second information designating a predetermined number of data, data formats of which are collectively converted, among the plurality of data;

acquiring, based on the acquired first information and the acquired second information, the predetermined number of conversion target data from the plurality of data;

converting data formats of the plurality of conversion target data by using a specific value;

embedding a predetermined number of pieces of specific information, a sum of which is the specific value, respectively to the predetermined number of conversion target data; and

transmitting each of the predetermined number of conversion target data added with each of the predetermined number of pieces of specific information to an information processing device.

11. The computer-readable storage medium storing the data conversion program according to claim 10, the process further comprising

transmitting the first information and the second information to the information processing device before the transmitting the conversion target data.

12. The computer-readable storage medium storing the data conversion program according to claim 10, the process further comprising

before the embedding, acquiring, from the storage, position information designating positions at where the predetermined number of pieces of specific information are embedded respectively in the predetermined number of conversion target data, wherein

in the embedding, the pieces of specific information are embedded at the respective positions indicated by the position information in the predetermined number of conversion target data.

13. The computer-readable storage medium storing the data conversion program according to claim 12, the process further comprising

transmitting the position information to the information processing device before the transmitting the conversion target data.

14. The computer-readable storage medium storing the data conversion program according to claim 10, wherein

in the converting, the respective data formats of the acquired plurality of conversion target data are converted by subtracting or adding the specific value respectively from or to values indicated by the acquired predetermined number of conversion target data.

15. The computer-readable storage medium storing the data conversion program according to claim 10, wherein

the acquiring the predetermined number of conversion target data, the converting, the adding, and the transmitting are repeatedly performed until all of the plurality of data are transmitted.

16. A data conversion device comprising:

a memory, and

a processor coupled to the memory and configured to execute a process, the process comprising;

acquiring, when receiving a plurality of data, first information and second information from a storage, the first information designating any data among the plurality of data, the second information designating a predetermined number of data, data formats of which are collectively converted among the plurality of data;

acquiring, based on the acquired first information and the acquired second information, the predetermined number of conversion target data from the received plurality of data,

extracting each of pieces of specific information embedded in each of the acquired predetermined number of conversion target data, and
