摘要

Methods and systems for securely storing data in a database are described herein. According to an aspect, a technique may include receiving data to be stored, dividing the data into a plurality of elements, encrypting each element of the plurality of elements with an encryption function, combining the encrypted elements to form a data attribute, and storing the data attribute in the database.

1. A method of searching a database having encrypted data attributes comprising the steps of:
receiving a search term; dividing the search term into a plurality of elements; encrypting each element of the plurality of elements with an encryption function; combining all of the encrypted elements to form an encrypted search term; modifying the encrypted search term by removing from the encrypted search term all non-alphanumeric characters and replacing the removed characters with alphanumeric characters; searching a database for records having data attributes matching the modified encrypted search term; retrieving the records having data attributes matching the encrypted search term; and decrypting the retrieved records.
