This is a summary of our current activities...
Integrity, Provenance and Trust (IPT) ensures that geospatial data products remain verifiably authentic and traceable across organizational boundaries throughout their entire lifecycle, from creation to consumption. This builds resilient data services that stakeholders can rely on when sharing and reusing data.

Our Immutable Catalog implements the STAC API while recording every catalog entry on a Hyperledger Fabric Blockchain. This ensures that data product metadata cannot be tampered with or silently altered, giving consumers a verifiable and tamper-proof record of what was published and when.
Immutable Catalog
Trusted OGC API Processes is an implementation of OGC API Processes that supports the deployment of provenance-recording-compliant processes. Execution produces execution metadata that is stored on the Blockchain, while the processed geospatial asset itself is stored on IPFS.

When it comes to Citizen Science, there is a great opportunity to enrich authentic datasets with contributions from citizens. As described by the FAIR (Findable, Accessible, Interoperable and Reusable) principle, a major concern is the R, as reusability requires trust in the citizens' observations. Trust cannot be achieved without the ability to identify users, which brings privacy by design into the equation...

With the concept of Data Centric Security (DCS), data can be protected in terms of integrity and confidentiality without relying on external security features. Independent of communication channel encryption like TLS over HTTP, DCS ensures protection for data at rest as well as in transit. This supports the reliable deployment of sensitive data in the cloud, independent of the security features provided by the cloud operator. This allows us to design, implement, and deploy a cloud-provider-independent solution.

The sharing of Citizen Science data with research, for example, requires seamless access to observations, independent of the actual operator. AUTHENIX, operated by Secure Dimensions, is an Authentication as a Service (AaaS) contribution to enable access for participating operators for Citizen Science stores and universities. AUTHENIX is registered with eduGAIN and provides login for academic users from approximately 2,870 universities. Also, login from Google and Facebook as well as the Open Geospatial Consortium is supported. More SAML-compliant login providers can be connected in a flexible way.
Secure Dimensions has been an active member of the Open Geospatial Consortium for many years. Standards like GeoXACML and OGC Web Services Security result from this collaboration. The current standardization activity is about GeoXACML 3.0.
