Abstract
Mashups have emerged as a Web 2.0 phenomenon, connecting disjoint applications
together to provide unified services. However, scalable access control for mashups
is difficult. To enable a mashup to gather data from legacy applications and
services, users must give the mashup their login names and passwords for those
services. This all-or-nothing approach violates the principle of least privilege
(not to mention the terms of service) and leaves users vulnerable to misuse of
their credentials by malicious mashups.
In this paper, we introduce Permits - a stateless approach to access rights delegation in mashups - and describe our complete implementation of a permit-based authorization delegation service.
