Systems and methods for partial matching searches of encrypted retained data |
摘要 |
Systems and methods are provided for encryption allowing partial matching searches to retrieve data that is retained in a database. A user identification number or other characteristic is stored in unencrypted form such that a wildcard search may be performed to retrieve one or more encrypted indexes associated with the unencrypted user identification. These encrypted indexes are then unencrypted by use of a key to determined their associated unencrypted index and corresponding targeted retained data. The targeted retained data may then be accessed by an authorized entity such as a law enforcement agency.
