Hashgraph and Truesense File CITI Patent
The Hashgraph Group, a Web3 and AI engineering firm, and Truesense, a developer of ultra-wideband sensing expertise, introduced the submitting of a European patent software for Steady Identification Belief Infrastructure (CITI). The brand new system is designed to attach proof of an individual’s bodily presence with a decentralized digital identification whereas defending private knowledge.
The patent software was submitted to the European Patent Workplace on April 4, 2026, and covers greater than 44 European international locations. The businesses are additionally making ready a patent submitting in the US.
CITI combines three applied sciences: ultra-wideband (UWB) sensing, decentralized identifiers (DIDs), and zero-knowledge proof (ZKP) cryptography. Collectively, these applied sciences make it doable to confirm that an individual was bodily current at a selected place and time with out revealing private data or location particulars.
The system works by first detecting an individual’s presence by means of UWB sensors. This occasion is then linked to a decentralized identification saved in a digital pockets. A verifiable credential is generated, containing a timestamp and cryptographic proof that’s completely recorded on a distributed ledger. Third events can later confirm the credential with out accessing delicate knowledge.
In keeping with the businesses, the expertise might be utilized in sectors the place identification verification is vital, together with finance, healthcare, sports activities, and leisure. For instance, an individual may enter a secured constructing utilizing a digital identification pockets as an alternative of an entry badge. The verification occasion could be recorded on the Hedera community, creating an auditable file whereas decreasing the danger of credential sharing.
