Identiproof is an easy to implement, fully secure and privacy protecting verifiable credentials Middleware from a co-author of the W3C Recommendation.

What problem does Identiproof solve? 

Whether they be IDs, educational qualifications, insurance certificates or Covid-19 vaccine documentation, organisations and individuals alike rely on credentials to establish aspects of their identity. However, most of these can be easily forged or misrepresented, expensive to create and difficult to verify. 

What are Verifiable Credentials? 

Identiproof is based on the World Wide Web Consortium (W3C) standard for verifiable credentials, co-authored by Crossword’s own Professor David Chadwick.This operates under the verifiable credential trust triangle:

Verifiable Credentials use cryptographic protocols to create tamperproof, digital credentials issued by a trusted authority which can be verified by anyone that the holder presents them to - all without compromising privacy.
