METHODS OF STORING AND RETRIEVING DATA IN/FROM EXTERNAL SERVER |
摘要 |
Provided are methods of storing and searching for data in encrypted form. The method of storing data in encrypted form includes: encrypting desired data from among data stored in a database; dividing an entire region of the stored data into a plurality of bucket regions and allocating an index to each of the bucket regions; identifying order information in a bucket region to which the encrypted data belongs; and storing the encrypted data, index information of the bucket region to which the encrypted data belongs, and the identified order information in an external server. When a database containing important data of at least one user is stored in an external server using the above storing method, the security and efficiency of the database can be increased.
