The Use of Attribute-Based Signature in a Blockchain for Health Records System Storage

Healthcare Blockchain technology, as a necessity for an effective patient-centered solution to healthcare applications, has immense potential and improves the quality value of electronic healthcare data (EHRs). In order to generate a solid outcome with a patientcentered strategy, we must address many issues and criteria in terms of privacy and also protection, the use of technology, and regulating processes. To maintain the integrity of EHRs embedded in Blockchains, we offer to multiple authorities an attribute-based signature technique in which a patient accepts a message based on the attribute, providing no specifics other than how he attested to it.
