Area of Science:

  • Health Informatics
  • Computer Science
  • Information Security

Background:

  • Privacy of prescription data is complex due to multiple involved parties, including non-medical personnel.
  • Both patient and doctor privacy are critical and require equal protection in prescription processes.
  • Prescription data requires identifiable elements for research and legal purposes, precluding complete anonymity.

Purpose of the Study:

  • To propose an enhanced e-prescription system focused on robust privacy protection.
  • To leverage smart card technology for secure storage and access of medical and insurance information.
  • To enable secure electronic prescription signing and introduce a delegation mechanism for enhanced privacy.

Main Methods:

  • Development of an e-prescription system integrating patient smart cards.

  • Smart cards function as portable repositories for medical records and insurance details.
  • Implementation of a strong proxy signature scheme for secure delegation of signing authority.

    • Main Results:

    • The proposed system facilitates instant access to patient data for healthcare providers.
    • Smart cards enable patients to electronically sign prescriptions, confirming acceptance.
    • A novel proxy signature scheme allows secure delegation of signing capabilities, protecting sensitive information.

    Conclusions:

    • The developed e-prescription system effectively addresses privacy concerns in drug prescription.
    • Smart card integration enhances data security, accessibility, and patient control.
    • The proxy signature scheme provides a secure and practical solution for delegation in e-prescription processes.
