BarcelonaNow Dashboard: citizen data exploration
BarcelonaNow is a free and open source component of the DECODE’s ecosystem to empower citizens with interactive dashboards for urban data exploration.
The massive amount and variety of urban data raise equally big challenges to allow citizens to make sense of open, private and common data for improving their daily life and fostering collective decision making.

DECODE In Action: Tested with real communities to build people-first digital cities
DECODE has worked with Barcelona and Amsterdam City Councils to build prototype applications and test them in partnership with real communities. See the tools in action below.
Digital Democracy and Data Commons (DDDC)
DECODE is integrated with the participation platform Decidim used by thousands to shape the city’s policy agenda. A new e-petition system offers people greater control, improves privacy and allows data sharing and visualization (integrating the BCNOW dashboard)
Citizens’ IoT Data Governance
Working with Ideas for Change and FabLab Barcelona, DECODE technology enabled Barcelona residents affected by pollution to collect and share encrypted data from environmental sensors anonymously with their communities, on their own terms.
Anonymous Proof of ID
The City of Amsterdam prototyped a ‘Passport Box’ and mobile web app that allows users to store encrypted passport data from the RFID-chip (inside the physical passport) onto their phone, and share attributes without disclosing sensitive personal information.
Ethical Social Network
GebiedOnline is a community-owned, member-based platform cooperative for sharing local news, events and meeting neighbours. DECODE tested a more privacy-preserving local social network approach and offered users more granular control over the data they share
