Disclosed herein is a method and apparatus for partially encoding/decoding data for a commitment service and a method of using encoded data. The apparatus includes an encoding/decoding module for encoding/decoding a database to be committed to a server using a private key of the user, obtained by accessing a key storage unit through a key management module which manages information about the private key of the user, stored in the key storage unit, and also encoding/decoding an SQL query required to use a DB committed to the server. The encoding/decoding module partially encodes/decodes one or more of table names, field names, and attribute values of the DB. In the present invention, the table names, field names, and field attribute values of the DB are partially encoded while the existing structure of the DB is maintained, and the partially encoded DB is committed to the server. |
