To preserve the private information of the outsourced database, it is important to encrypt the database. Also it is necessary to provide a query processing scheme without decrypting the encrypted data. For this, we propose a group order preserving data encryption scheme based on periodic functions (GOPES). Our GOPES generates encryption signatures based on data groups and periodic functions. With this, we can can guarantee the data privacy.
