METHOD AND APPARETUS FOR ENCODING/DECODING PARTIAL OF DATA AND METHOD FOR USING THE DATA

摘要

PURPOSE: A partial data encoding/decoding apparatus for a consignment service and a method thereof are provided to offer a security reinforced service by partially encoding a table name, a field name, and a field property. CONSTITUTION: A key repository(150) stores the password of a user. If the password is inputted by the user, a key manage module(140) changes the password and stores the changed password to the key repository. An encoding/decoding module(130) uses the password key and performs encoding process for database in order to consign the password to a server. The encoding/decoding module performs encoding for an SQL(Structured Query Language) query for using the consigned database.
