1. DEMO OF THE BDE PILOT FOR
SECURE SOCIETIES
2nd Workshop on “Big Data in Secure Societies”18/10/2016

2. SC7 – Secure Societies
SC7 societal challenge is about protecting freedom and security
of Europe and its citizens. In other words:
 enhance resilience against natural and man-made disasters
 develop novel solutions for the protection of critical infrastructure
 fight crime and terrorism
 improve border security
 provide enhanced cyber-security

3. Main Objective of the SC7 Pilot
Automatically detect
land cover evolution,
caused by physical or
human activities, and
alert users
accordingly.

4. Technical Objectives
Track changes in land cover/land use by integrating
heterogeneous information sources:
 Detect changes using satellite images
 Monitor related information in social media

programme funded and managed by EC
o Same area acquired every 6 days with 2 satellites
◎ Twitter
o Free Twitter Public Streams API and specific user accounts
o Plain text along with metadata in JSON format
◎ Reuters
o News articles through RSS feeds in XML format

8. Pilot Status
◎ Change Detection Workflow
o System able to search, download and (pre-)process images in parallel (Spark)
◎ Event Detection Workflow
o System able to continuously monitor social media and news agencies
o Events clustered and mapped to geolocations
◎ Activation Workflow
o GIS interface (Sextant) allows users to activate the two workflows
o Geographic information stored in Strabon and queried through SPARQL
◎ All components and workflows setup on BDE infrastructure

9. Future Developments
◎ Overall SC7 Pilot
o Add cybersecurity mechanisms (e.g. authentication / authorization)
o Add more data sources for both workflows (e.g., HR satellite images)
◎ Change Detection Workflow
o Improve classification accuracy
◎ Event Detection Workflow
o Dockerize Spark version
◎ Activation Workflow
o New GUI functionalities according to user feedback
