Patent number: 10645065Abstract: Concepts and technologies disclosed herein are directed to proxy-based database encryption. According to one aspect, a database encryption proxy system can receive, from a database client, input of a Structured Query Language (“SQL”) statement and data to create an encrypted database table. At least a portion of the data is marked with an encrypted identifier to identify which data is to be encrypted by the proxy-based database. The database encryption proxy system can generate a random string for the portion of the data that is marked with the encrypted identifier. The database encryption proxy system can convert the SQL statement into a converted SQL statement that includes the random string in place of the portion of the data marked with the encrypted identifier and can send the converted SQL statement to a cloud database service that is configured to create the encrypted database table based upon the converted SQL statement.Type: GrantFiled: February 28, 2017Date of Patent: May 5, 2020Assignees: AT&T Intellectual Property I, L.P., AT&T Mobility II LLCInventors: Xidong Wu, Zhengye Liu, Mario Kosseifi
