Liquid Avatar Technologies Inc. announced that its Liquid Avatar Verifiable Credential Ecosystem ("LAVCE") for sharing digital health information successfully works with other digital health credential systems based on the Linux Foundation Public Health Cardea project. This interoperability means that LAVCE's credentials for digital health information such as proof of a valid COVID-19 test, vaccine, and/or exemption can be used across multiple systems and platforms, thereby helping people to resume school, work, and travel in a way that increases public safety while preserving privacy and preventing fraud. Liquid Avatar Technologies demonstrated LAVCE's interoperability at a recent hackathon style event for companies participating in the Cardea community, seamlessly issuing, exchanging, and verifying health related data with other participating systems at the event. LAVCE's successful demonstration illustrated the power of interoperable verifiable credentials as a way to transform how share and trust digital health information. The LAVCE platform can be integrated with healthcare facilities, testing labs, government agencies, schools, sports arenas, transportation, trade shows, and workplaces to confirm health status and assist efforts to reduce new outbreaks. The platform can also receive, verify, and issue credentials to other products and services that are compatible with Linux Foundation projects including Hyperledger Aries, Hyperledger Indy, and Cardea. LAVCE's digital health credentials are based on global standards as Liquid Avatar Technologies is a member of the Good Health Pass Collaborative, and is supported by the Indicio Network, a global blockchain network for decentralized identity services, of which Liquid Avatar Technologies is a founding member. Both Liquid Avatar Technologies and Indicio are founding and steering committee members of Cardea, a Linux Foundation Public Health initiative to promote secure, privacy-preserving sharing of health status data in an interoperable way. To encourage future adoption, Liquid Avatar Technologies will soon offer a software development kit (SDK) for both iOS and Android that can be embedded in and power apps, corporate and government portals, and other solutions to make it possible for all types of organizations to support digital wallets and verifiable credentials easily and effectively.
