In the digital world, a scenario in which publishers offer digital contents directly to customers is technically feasible. However, the role of the library as a middle tier between publisher and customer offers so many advantages that it should be retained. But both two- and three-tier digital library services must protect the transactions between content owners and users. These not only include the protection of the content, but also include payment, assertion of copy and usage rights, and protection of privacy. The talk contrasts two different security technologies that enable these transactions: secure connections and secure containers. We explain the concepts of both approaches, using the IBM cryptolope technology as an example for secure containers. We discuss the advantages and drawbacks of Cryptolopes in comparison to secured communication channels like SSL or S-HTTP.
