From “security for privacy” to “privacy for security”

This article envisions the use of context-awareness to improve single sign-on solutions (SSO) for mobile users. The attribute-based SSO is expected to increase users´ perceived ease of use of the system and service providers´ authentication security of the application. From these two features we derive two value propositions for a new business model for mobile platforms. The business model can be considered as an instantiation of the privacy-friendly business model pattern presented in our previous work, reinforcing our claim that privacy-friendly value propositions are possible and can be used to obtain a competitive advantage.
