| Definitionskos:definition | n an era of growing data volumes and geospatial analysis demands, maintaining Integrity, Provenance, and Trust (IPT) is critical, especially in distributed systems where data availability can fluctuate. The OGC Testbed 20 IPT activity addresses this need by developing resilient data services that safeguard IPT throughout the data lifecycle. Two IPT Server instances were demonstrated in the Testbed 20 IPT activity by Secure Dimensions, which used the Federated Agile Collaborative Trusted System (FACTS) to manage Smart Certificates, and Spacebel, which leveraged Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) for data verification. These servers ensure that data remains reliable and traceable by validating its origin and history, supporting cross-organizational trust without altering legacy data formats. The FACTS ecosystem that was demonstrated by Secure Dimensions provides a trusted process for managing data through Smart Certificates. The two processes demonstrated, Trusted Teapot and Trusted Watermarking, validated certificates, maintained data integrity, and generated new certificates for outputs. Meanwhile, Spacebel’s IPT Server demonstrated verification and authenticity of Earth Observation (EO) data sources, ensuring the integrity of information exchanged within the EO data supply chain. Together, these IPT Server instances provide examples of scalable frameworks for applying IPT principles, supporting the development of resilient data services that uphold reliability and trust across distributed networks. To validate cross-component compatibility and demonstrate seamless data exchange, nine Technical Interoperability Experiments (TIEs) were conducted between these IPT servers and various tools, including a PDF Generator from SatCen and tools like UniResolver and UniVerifier. These experiments successfully established interoperability between Smart Certificates and Verifiable Credentials, confirming the flexibility and scalability of the IPT systems. Additionally, the TIEs identified challenges such as the need for JSON-LD 1.1 compatibility and suggested alternative encoding strategies, enhancing the potential for IPT systems to support diverse geospatial data services in real-world scenarios. |
