DEMO eHealth: Redactable Signatures for Sharing Authentic Information from Digitally Signed EHR

The video shows the generation of a signed HER and how PRISMACLOUD's Selective Authentic Sharing service is facilitating the cryptographic primitive of redactable signature schemes to allow a patient to redact information not necessary to share with a third party and produce a verifiable document. The signature is generated using a remote signature service that has been build on top of PRISMACLOUD's implementation of a generic redactable signature scheme. The verification is shown to take place locally in an Android app or in the cloud.
