Conditional Purchase Orders
4th ACM Conference on Computer and Communications Security, ACM Press, April 1997, pp. 117-124.
ABSTRACT: We propose a system of commerce based on the Conditional Purchase Order (CPO). Individual buyers issue CPOs, which are evaluated and fulfilled by sellers. There are mechanisms to bind the buyer to the transaction once the conditions are met. Additional enhancements include the ability to add anonymity, and assurances of product quality by trusted third parties.
