Email system architecture for HITECH compliance

摘要

This paper aims at proposing a guideline for the health care industry covered under Health Insurance Portability & Accountability Act (HEPAA). In this paper Key Compliance Attributes (KCA) for email system are defined. At the next level architecture for Email Handler and Spam Filter (EHSF) is devised. Two soft computing models named "user behaviour prediction model" and "genetic algorithm compliance model" are proposed. The healthcare industry can implement it to guard against unauthorized access to the Electronic Protected Health Information (E-PHI). Protected Health Information (PHI) refers to any health information that could be expected to reveal the identity of an individual. It includes the explicitly linked data and also that which could be used to determine the identity of an individual. To secure E-PHI according to HTPAA rules employs secure transmission systems and/or encryption when e-mailing or transmitting patient data. This paper also proposes the best email encryption standard for Health Information Technology for Economic and Clinical Health (HITECH) Act compliance to secure PHI.
