Citizen Observatory Framework with Access Management Federation in GEOSS - Bart De Lathouwer

  1. 1. Citizen Observatory Framework with Access Management Federation In GEOSS 10th October, 2013, Neusiedl am See ENVIP’2013 Bart De Lathouwer Interoperability Program OGC
  2. 2. The bare bones… • Project started 1st Nov, 2012 and will run for 4 yrs • Funded under the European Commission’s Framework Programme 7 (Grant No: 308513) • Crowd sourced environmental data to aid decision making • Introduce quality measures and reduce uncertainty • Fusion of crowdsourced data with reference data… • Spatial Data Infrastructure - like initiatives – National SDI’s in UK, Greece and Germany – INSPIRE – GEOSS
  3. 3. FP7-ENV-2012 observatories Name Lead Topic Citclops Barcelona Digital Centre Tecnològic (Spain) Coast and ocean optical monitoring WeSenseIt University of Sheffield (UK) Water Management CITI-SENSE Nilu (Norway) Air quality Omniscientis Spacebel (Belgium) COBWEB UEDIN (UK) Odour monitoring Environment
  4. 4. Essential context – WNBR • UNESCO Man and Biosphere Programs (MAB) World Network of Biosphere Reserves – Sites of excellence to foster harmonious integration of people and nature for sustainable development through participation, knowledge sharing, poverty reduction and human well-being improvements, cultural values and society's ability to cope with change, thus contributing to the Millennium Development Goals • 610 reserves in 117 countries
  5. 5. COBWEB Biosphere Reserves 1. UK (Wales): Biosffer Dyfi 2. Germany: Wadden See and Hallig Islands 3. Greece: – – Mount Olympus Gorge of Samaria Left open possibility of expansion to further BRs later in project
  6. 6. Why the need for Authentication? • Not all observers are created equal – Occasional observer – Scientific observer – Influence on the quality indicator of the observation • Not all observations should have unrestricted access – Endangered species
  7. 7. Authentication and Single Sign-On • Recommendations – Federated solution (lightest impact on GCI) • OpenID and SAML-2 to be used – Data provider support for a set of “trusted” OpenID identity servers to be used with SAML-2 user management systems • USA Gov. has such a list (Google &VeriSign) • INSPIRE doesn’t have such a list – Authentication is the current primary goal • Access control is a future interest – User interaction is the current primary goal • Programmatic authentication is a future interest 7
  8. 8. Authentication and Single Sign-On • The AIP-6 access management federation includes: – – – – SAML-2 SAML-2 SAML-2 SAML-2 Service Provider (SP) Identity Provider (IdP) Discovery Service (DS) / OpenID Trust Gateway
  9. 9.
