Controlled EHR access in secured health information system

Health care systems are vulnerable to many possible attacks leading to challenge the data security. While designing information systems, this problem is addressed by proposing and testing various designs. Through this paper, we describe a two-tier architecture to access electronic health records (HER) data with the use of interactive trust negotiation. The preliminary results suggest that security measures are not confined to systems alone but data correlations offer much promise for developing a secured health care information system.
