Paper Abstract

The deadline of HIPAA (Health Insurance Portability and Accountability Act) Security Rules has passed on February 2005; therefore being HIPAA compliant becomes extremely critical to healthcare providers. HIPAA mandates healthcare providers to protect the privacy and integrity of the health data and have the ability to demonstrate examples of mechanisms that can be used to accomplish this task. It is also required that a healthcare institution must be able to provide audit trails on image data access on demand for a specific patient. For these reasons, we have developed a HIPAA compliant auditing system (HCAS) for image data security in a PACS by auditing every image data access. The HCAS was presented in 2005 SPIE. This year, two new components, LDSE (Lossless Digital Signature Embedding) and LTVS (Patient Location Tracking and Verification System) logs, have been added to the HCAS. The LDSE can assure medical image integrity in a PACS, while the LTVS can provide access control for a PACS by creating a security zone in the clinical environment. By integrating the LDSE and LTVS logs with the HCAS, the privacy and integrity of image data can be audited as well. Thus, a PACS with the HCAS installed can become HIPAA compliant in image data privacy and integrity, access control, and audit control.
