Abstract: Digital information is increasingly more and more important to underpin interactions, transactions and exchanges of knowledge. On the other hand, leakages of sensitive digital information can spread rapidly with harmful effects for people, organizations and governments. This paper focuses on the problem of protecting confidential information from unauthorised disclosures, subject to time-based criteria: it is a common issue in the industry, government and day-to- day life. We introduce an innovative service, the Time Vault Service, that leverages the emerging Identity- based Encryption (IBE) cryptography schema to enforce time-based confidentiality of digital documents and simplify their distribution. We discuss the advantages of this approach against a similar approach based on traditional cryptography. A working prototype of the Time Vault Service is described, as proof of the concept.
