Abstract

A data storage device includes a memory and a controller, where the controller receives an indication of data to be anonymized. The controller also parses a data element to be stored and generates a copy of one or more data portions to be anonymized. The controller also deletes one or more data portions to be anonymized to generate modified data elements to be stored. The controller also generates a copy of the modified data element to be stored with deduplication. Accordingly, the data storage device takes into account data anonymity (i.e., anonymity-aware deduplication) during deduplication, thereby enabling efficient deduplication even in the presence of anonymous data.

Description

technical field [0001] The present invention generally relates to the fields of data protection and backup, and more particularly, to a data storage device and method for anonymous-aware deduplication. Background technique [0002] Typically, data backups are used to protect and restore data in the event of a data loss in the primary storage system. Examples of data loss events may include, but are not limited to, data corruption, hardware or software failure in primary storage devices, accidental deletion of data, hacking, or malicious attacks. Therefore, for security reasons, separate backup systems or secondary storage (eg, data storage devices) are widely used to store data backups that exist in the primary storage system. [0003] Currently, data anonymization is used to protect the privacy of confidential or private information, such as credit card numbers, social security numbers. In data anonymization, confidential or personal data, such as personally identifiable ...
