In the public sector, PIAs could become a prerequisite for IT project procurement. Although they will involve financial costs, the benefits may be significant. It is cheaper to include privacy concerns in the design phase of systems than to make them privacy compliant at a later stage.Privacy enhancing technologies (PETs) could be systematically integrated into systems development. An important PET principle is that systems should only collect data on a need to know -not a nice to know -basis. Delivering services without collecting excess data is cost-effective as well as socially desirable.International privacy standards can enhance consumer trust and promote equal privacy protection worldwide; and they encourage corporate response.There is a rapid development of e-services and a new security situation. New technologies such as RFID, biometrics and pervasive computing are also developing rapidly and thus create new possibilities and threats.This report shows that the value of privacy is underestimated by citizens, policy makers and enterprises. It concludes that there is need for more research on mid-and long-term effects of weakened privacy, and more public dialogue is needed on these issues.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
