Abstract
A data protector is described. In an implementation, the data protector promotes and enforces a data retention policy of a data consumer. In an implementation, the data protector limits access to sensitive data to the data consumers. A key manager provides a time-limited encryption key to the data protector. Responsive to collection of the time-limited encryption key from the key manager and sensitive data from a data provider, the data protector encrypts the sensitive data with the time-limited encryption key effective to produce encrypted sensitive data. In some embodiments, the data protector provides a data consumer with access to the encrypted sensitive data and the key manager provides the data consumer with access to the time-limited encryption key to decrypt the encrypted sensitive data. The key manager deletes the time-limited encryption key in compliance with the data retention policy of the data consumer.
