Forgetting with Puzzles
Ghous Amjad, Shujaat Mirza, Christina Pöpper · 2018
Digital forgetting deals with the unavailability of content uploaded to web and storage servers after the data has served its purpose. The content on the servers can be deleted manually, but this does not prevent data archival and access at different storage locations. This is problematic since then the data may be accessed for unintended or even malicious purposes long after the owners have decided to abandon the public availability of their data. Approaches which assign a lifetime value to data or use heuristics like interest in data to make it inaccessible after some time have been proposed, but digital forgetting is still in its infancy and there are a number of open problems with the proposed approaches.
