Abstract: A data deletion notification service registers data repositories that store personal data. The service receives requests from users to delete personal data, sends notifications of the deletion requests to the registered data repositories, and stores deletion records recording the deletions and a timestamp associated with the deletion request. The service may wait for confirmation of the deletions from the data repositories, resending the deletion requests if a confirmation is not received, and recording confirmation in an audit record. Data repositories performing a restoration may request, from the service, a list of users that have requested deletion of personal data since the time of the creation of the backup used for restoration. The service may generate, based on deletion records with corresponding timestamps, the list of users and respond to the request with the list. Confirmations of the deletions may be tracked, stored and made available via an audit interface.
