A multitude of workflows undergo acceleration and refinement processes due to constant developments in the information technology. Digital identity is an important tool within this context because it helps to save costs, automatise processes and increase security. The Fraunhofer-Competence Center Public Key Infrastructures (CC PKI) is establishing a basis for further developing this potential on behalf of the Fraunhofer Gesellschaft. Fraunhofer Institute SIT is responsible for designing, establishing and operating the Public Key Infrastructure for all of Fraunhofer's employees. The smart chip identity, based on a chip card, reduces costs and offers a big variety of possible uses – from the electronic holiday card to laptop protection.
