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.

摘要翻译： 提供了系统和方法用于加密，允许部分匹配搜索来检索数据库中保留的数据。 用户标识号或其他特性以未加密形式存储，使得可以执行通配符搜索以检索与未加密的用户标识相关联的一个或多个加密索引。 这些加密索引然后通过使用密钥来加密，以确定其相关联的未加密索引和相应的目标保留数据。 然后可以由诸如执法机构的授权实体访问目标保留的数据。
