Using timed-release cryptography to mitigate the preservation risk of embargo periods
Due to temporary access restrictions, embargoed data cannot be refreshed to unlimited parties during the embargo time interval. A solution to mitigate the risk of data loss has been developed that uses a data dissemination framework, the Timed-Locked Embargo Framework (TLEF), that allows data refreshing of encrypted instances of embargoed content in an open, unrestricted scholarly community. TLEF exploits implementations of existing technologies to “timelock” data using timed-release cryptology so that TLEF can be deployed as digital resources encoded in a complex object format suitable for metadata harvesting. The framework successfully demonstrates dynamic record identification, time-lock puzzle encryption, encapsulation and dissemination as XML documents. We implement TLEF and provide a quantitative analysis of its successful data harvest of time-locked embargoed data with minimum time overhead without compromising data security and integrity.
