Designing for Trust

摘要

Designing for trust requires identification of the sometimes subtle trust assumptions embedded into systems. Defining trust as the intersection of privacy, security and reliability can simplify the identification of trust as embedded in a technical design. Yet while this definition simplifies, it also illuminates a sometimes overlooked problem. Because privacy is an element of trust, purely operational definitions of trust are inadequate for developing systems to enable humans to extend trust across the network. Privacy is both operational (in the sharing of data) and internal (based on user perception of privacy). Designing trust metrics for the next generation Internet, and indeed implementing designs that embed trust for any digital environment, requires an understanding of not only the technical nuances of security but also the human subtleties of trust perception. What is needed is a greater understanding of how individuals interact with computers with respect to the extension of trust, and how those extensions can be addressed by design.
