Method and apparatus for managing data, and data management system using the same
First Claim
1. A method for managing data, comprising:
- receiving data collected by a sensor, the data comprising an encrypted section and a non-encrypted section, the encrypted section comprising a first encrypted data entry and a second encrypted data entry;
using a mapping table to map the first encrypted data entry and the second encrypted data entry to a first matched information entry without decrypting the first encrypted data entry and the second encrypted data entry, wherein the first encrypted data entry corresponds to a first decrypted data value that is different from the first matched information entry, and wherein the second encrypted data entry corresponds to a second decrypted data value that is different from the first matched information entry and the first decrypted data value; and
based on at least the first matched information entry, performing, via a hardware processor, an analysis of the data without decrypting the encrypted section,wherein the first decrypted data value and the second decrypted data value indicate measured values by a sensor, andwherein the first matched information indicates processed information obtained by processing the measured values according to a predetermined criterion.

Abstract
A method for managing data, comprising: receiving data about information collected by a sensor, in which at least a part of the data is encrypted; and performing an analysis in a state where both non-encrypted section and encrypted section of the data are not decrypted.
Also, a method for managing data encryption, comprising: allowing a sensor or an intermediate network device to encrypt at least a part of data about collected information; allowing the sensor or the intermediate network device to transmit the at least partially encrypted data; allowing a data management apparatus to receive the at least partially encrypted transmitted data; allowing the data management apparatus to store the at least partially encrypted received data; and allowing the data management apparatus to perform an analysis in a state where both non-encrypted section and encrypted section of the at least partially encrypted data are not decrypted.

6. A method for managing data encryption, comprising:
-
encrypting, by one of a sensor and an intermediate network device connected between the sensor and a data management apparatus, at least a part of data collected by the sensor to yield partially encrypted data comprising an encrypted section and a non-encrypted section, the encrypted section comprising a first encrypted data entry and a second encrypted data entry; transmitting, by the one of the sensor and the intermediate network device, the partially encrypted data; receiving, by the data management apparatus, the partially encrypted transmitted data; storing, by the data management apparatus, the partially encrypted received data; using a mapping table to map the first encrypted data entry and the second encrypted data entry to a first matched information entry without decrypting the first encrypted data entry and the second encrypted data entry, wherein the first encrypted data entry corresponds to a first decrypted data value that is different from the first matched information entry, and wherein the second encrypted data entry corresponds to a second decrypted data value that is different from the first matched information entry and the first decrypted data value; and based on at least the first matched information entry, performing, by the data management apparatus, an analysis of the partially encrypted data without decrypting the encrypted section, wherein the first decrypted data value and the second decrypted data value indicate measured values by a sensor, and wherein the first matched information indicates processed information obtained by processing the measured values according to a predetermined criterion. - View Dependent Claims (7, 8)

9. A data management apparatus, comprising:
-
a hardware processor; and a non-transitory computer-readable storage medium storing instructions which, when executed by the hardware processor, cause the hardware processor to perform operations comprising; receiving data collected by a sensor, the data comprising an encrypted section and a non-encrypted section, the encrypted section comprising a first encrypted data entry and a second encrypted data entry, using a mapping table to map the first encrypted data entry and the second encrypted data entry to a first matched information entry without decrypting the first encrypted data entry and the second encrypted data entry, wherein the first encrypted data entry corresponds to a first decrypted data value that is different from the first matched information entry, and wherein the second encrypted data entry corresponds to a second decrypted data value that is different from the first matched information entry and the first decrypted data value, and based on at least the first matched information entry, performing an analysis of the data without decrypting the encrypted section, wherein the first decrypted data value and the second decrypted data value indicate measured values by a sensor, and wherein the first matched information indicates processed information obtained by processing the measured values according to a predetermined criterion. - View Dependent Claims (10, 11, 12)
