How does CERTUS guarantee lifelong verification?

The underlying mathematical proofs and the immutability of the data embedded within the KSI Blockchain technology underlying the CERTUS solution ensure verifiability for life. The public anchor of the KSI Blockchain (published every month in the UK Financial Times and on other mass media channels such as Twitter), combined with the digital seal of the CERTUS secured document, allows any verifier to run the open algorithm and guarantee the document’s integrity.
