Problems solved by technology

This technique can restrict client access to unauthorized information
However, this existing technology cannot limit the illegal actions of insiders with legitimate access rights (e.g., database administrators) or those with OS privileges (OSprivilege)
[0007] In order to solve the above problems, a method of encrypting confidential information in user applications is proposed, but in this case, all user applications involving confidential information need to be encrypted / decrypted, so it is necessary to provide Encryption / decryption codes are provided, so it is very inconvenient

Abstract

According to an embodiment of the present invention, the invention relates to a method for encrypting a database and a database server. The method comprises encrypting a data value included in a data table stored in a memory and storing the encrypted data value in a persistent storage medium. The method comprises the following steps: a step of generating an encrypted data value based on the data value included in the data table stored in a memory; a step of generating a hash value that matches the encrypted data value at least partially based on the data value and positional information of the data value; and a step of determining to write the encrypted data value and the hash value on a persistent storage medium.

Description

technical field [0001] The present invention relates to database encryption, and more particularly to encrypting and storing data to protect the data from access by authorized internal administrators. Background technique [0002] With the development of computer and Internet technology, more and more attention has been paid to databases that can effectively store large amounts of data and search them conveniently and quickly with desired retrieval conditions. Today's database systems allow the storage and retrieval of vast amounts of information. Some of this information may include sensitive information such as credit card numbers. [0003] In particular, in the financial industry and in databases that collect and manage personal information on Internet portal sites, in order to prevent unauthorized users from judging or illegally recording information processed in computers, or to protect the information processing services of users with legal rights Database security i...
