SEMPER is a European R&D project in the area of secure electronic commerce over open networks, especially the Internet. It is executed by an interdisciplinary consortium, combining experts from social sciences, finance, retail, publishing, IT and telecommunications, and has established liaisons with several related efforts.

SEMPER is part of the European Commission's ACTS Programme (Advanced Communications Technologies and Services), executing Task 503. Funding is provided by the partner organisations, the European Union and the Swiss Federal Department for Education and Science.
