Today's increasingly digital societies and markets mandate consistent procedures for the access, processing and storage of information. A recurrent theme is the need for regulatory-compliant storage as an essential underpinning enforcing long-term data retention and life-cycle policies. Here, the authors introduce a Write-Once Read-Many (WORM) storage system providing strong assurances of data retention and compliant migration, by leveraging trusted secure hardware in close data proximity. This is important because existing compliance storage products and research prototypes are fundamentally vulnerable to faulty or malicious behavior, as they rely on simple enforcement primitives that are ill-suited for their threat model.
