Applying secret sharing for HIS backup exchange

Area of Science:

• Health Informatics
• Information Security
• Disaster Management

Background:

• Securing business continuity is vital for hospitals, especially during disasters.
• Backing up hospital information systems (HIS) at remote sites is a key strategy.
• Privacy requirements for sensitive data increase HIS backup costs.

Purpose of the Study:

• To evaluate the feasibility of commercial secret sharing solutions for HIS backup.
• To assess the cost-effectiveness and security of HIS data exchange between hospitals.

Main Methods:

• Simulations were conducted to test a commercial secret sharing solution.
• The study focused on the practical application of secret sharing for HIS backups.

Main Results:

• The commercial secret sharing solution is feasible for creating an HIS backup exchange platform.
• The method effectively addresses the cost challenges associated with privacy-sensitive data.

Conclusions:

• Secret sharing offers a viable solution for inter-hospital HIS backup exchange.
• A standardized contract template is necessary for successful implementation.
