Method and apparatus for securely storing data in a database

摘要

A method of securely storing data in a memory on a computer including a processor is provided. The method includes receiving unencrypted data; randomly selecting a key, wherein the key is a character of an alphabet of a data type of the unencrypted data; creating partially encrypted data by encrypting the unencrypted data by randomly mapping each character of the alphabet of the data type of the unencrypted data to a character of an alphabet of a data type of encrypted data, except each character of the unencrypted data matching the key is not encrypted; and storing the partially encrypted data in the memory.

1. A method of securely storing data in a memory on a computer including a processor, the method comprising:
receiving unencrypted data; randomly selecting a key, wherein the key is a character of an alphabet of a data type of the unencrypted data; creating partially encrypted data by encrypting the unencrypted data by randomly mapping each character of the alphabet of the data type of the unencrypted data to a character of an alphabet of a data type of encrypted data, except each character of the unencrypted data matching the key is not encrypted; and storing the partially encrypted data in the memory, wherein the alphabet of the data type of the encrypted data comprises: a character including a right edge and a bottom edge of a square; a character including a left edge, the bottom edge and the right edge of the square; a character including the left edge and the bottom edge of the square; a character including a top edge, the right edge and the bottom edge of the square; a character including the square; a character including the top edge, the left edge and the bottom edge of the square; a character including the top edge and the right edge of the square; a character including the left edge, the top edge and the right edge of the square; and a character including the left edge and the top edge of the square, and wherein each of the characters of the alphabet of the data type of the encrypted data is represented as an image file.
