WCT's Security Practices in Medical Data Sharing
Cross-institutional sharing of medical data is crucial for precise diagnosis and treatment, but privacy protection is the biggest obstacle. WCT utilizes encryption technology to put patient medical record data on the blockchain, allowing patients to independently set the scope of data sharing (e.g., only authorizing specific hospitals). Hospitals use WCT to pay for data query fees, with the fees going directly to the patients. After a medical alliance introduced WCT, the time for cross-hospital consultations was reduced from 3 days to 4 hours, the rate of repeated examinations for patients decreased by 35%, and it achieved “data available but not visible,” protecting patient privacy.
