Abstract

Claims (36)

1. A data management computer for processing encryption of at least one original data including computer hardware that causes the computer to perform:

dividing each original data of at least one original data into a plurality of data elements and randomly assigning coordinate information to each of the divided data elements of at least one original data;

encrypting at least one original data by separating each coordinate information assigned to a plurality of data elements into at least one piece; and

assigning data information or arrangement information to each of the separated coordinate information and storing them.

2. The data management computer of claim 1 , wherein the coordinate information is information generated by a coordinate display means consisting of a plurality of rows and columns and having different symbols assigned to each row and column, and wherein separating each coordinate information assigned to the plurality of data elements into at least one piece is separating the coordinate information of a specific column or specific row of a coordinate display means.

3. The data management computer of claim 1 , wherein the separated coordinate information is encrypted.

4. The data management computer of claim 1 , wherein when the encrypted original data is used by a utilizer, provides predetermined profit to the provider of the original data.

5. A data security method using data management computer processing encryption of at least one original data comprising:

dividing, a data management computer, each original data of at least one original data into a plurality of data elements and randomly assigning coordinate information to each of the divided data elements of at least one original data;

encrypting, a data management computer, at least one original data by separating each coordinate information assigned to a plurality of data elements into at least one piece;

assigning, a data management computer, data information or arrangement information to each of the separated coordinate information and storing them.

6. A system for data security comprising:

a data management computer including computer hardware that causes the system to perform:

receiving a plurality of original data corresponding to security objects provided by users;

dividing each original data of the plurality of original data into data elements and generating divided data element information in which the divided data elements are arranged for each original data;

generating data element arrangement information by randomly arranging data elements for each original data included in the divided data element information in one coordinate display means having a plurality of rows and columns and capable of assigning coordinates to each row and column;

generating data coordinate information including information of a plurality of data coordinates arranged in the order of data elements of the original data by extracting coordinate information of data elements corresponding to each original data from the data element arrangement information; and

deleting the plurality of original data and the divided data element information.

7. The system for data security of claim 6 , further comprising: receiving and managing basic personal information such as names (titles), phone number and address entered by users who want the security of the data, and user information such as ID and password (PW) for system access; and receiving and managing basic information such as names (titles), phone numbers and addresses entered by utilizers who want to utilize the users' data.

8. The system for data security of claim 6 , wherein the data management computer further comprising: setting a data range for generating data coordinate information for each original data of the plurality of original data.

9. The system for data security of claim 6 , wherein the division of the plurality of original data into data elements is to divide the original data into units such as syllables, numbers, words, or sentences.

10. The system for data security of claim 6 , wherein the one coordinate display means is generated or set in advance.

11. The system for data security of claim 6 , wherein when the data is to be used due to the need of the information subject who provided the original data or at the request of the user, the data management computer decrypts the data included in the original data based on the coordinate information of the data coordinate information, and provides to the information provider or utilizer.

12. The system for data security of claim 6 , further comprising: receiving and managing utilization information of decrypted original data of information providers or utilizers of the original data.

13. The system for data security of claim 12 further comprises a user interface capable of confirming the original data by being output to the user terminal of the information provider of the original data or the utilizer terminals of the utilizers.

14. A data security method comprising:

Receiving, by a data management computer, a plurality of original data corresponding to security objects provided by users;

dividing, by the data management computer, each original data of the plurality of original data into data elements and generating divided data element information in which the divided data elements are arranged for each original data;

generating, by the data management computer, data element arrangement information by randomly arranging data elements for each original data included in the divided data element information in one coordinate display means having a plurality of rows and columns and capable of assigning coordinates to each row and column;

generating, by the data management computer, data coordinate information including information of a plurality of data coordinates arranged in the order of data elements of the original data by extracting coordinate information of data elements corresponding to each original data from the data element arrangement information; and

deleting, by the data management computer, the plurality of original data and the divided data element information.

15. The data security method of claim 14 , further comprising:

receiving, by the data management computer, a request for confirmation of the user's original data entered by the user who has completed user authentication as the information provider from the user terminal;

inquiring, by the data management computer, the data element arrangement information associated with data coordinate information of original data stored according to the request of the user terminal;

decrypting, by the data management computer, the original data based on the data coordinate information and the inquired data element arrangement information; and

transmitting, by the data management computer, the decrypted original data to the user terminal.
