In conjunction with this the <i>“concerns about privacy transcend the health care setting. Americans believe that their privacy rights are not adequately protected”</i> [<span style='color:#FF6600'>2</span>]. These concerns were reflected in other countries including New Zealand. The New Zealand government developed the Health Information Privacy Code 1994 (http://www.knowledge-basket.co.nz/privacy/comply/HIPCWWW.pdf) to ensure privacy of health information.</font></span></div> <div class="MsoNormal"><span lang=EN-NZ><font color="#000000">It is becoming increasingly difficult for the lawmakers to stay in line with new developments in our ever-accelerating technology. Privacy and security requirements are no exception.</font></span></div> <div class="MsoNormal"><span lang=EN-NZ><font color="#000000"><i>“With the advance of technology have come a variety of challenges to our privacy. It’s not that the Internet causes loss of privacy-but it has made us more aware of the issues surrounding privacy. The complexities involved in maintaining our privacy and security in a world where information is increasingly public can be daunting.”</span><span lang=EN-NZ></i> [<span style='color:#FF6600'>3</span>]. Compounding this problem is the globalisation of information and the lack of global legislation to protect the privacy of our health information, <i>“it is easy to understand why some kinds of information should be accorded special status and legal protection based on their sensitivity and the great damage that can occur from unconsented disclosure.”</i>[<span style='color:#FF6600'>4</span>]. The protection of our health information is imperative to maintaining the individual’s privacy.</font></span></div> <div class="MsoNormal"><span lang=EN-NZ><font color="#000000"><i>“The essence of security is to protect the availability, integrity and confidentiality of data and systems”</span><span lang=EN-NZ></i>[<span style='color:#FF6600'>5</span>]. The lack of security has the potential to put: the patient, the clinician, the system and the organization at risk, the reason is that medical organizations <i>“tend to focus our greatest emphasis on patient care. But once you understand how profoundly a lack of IT security can effect your organization, right down to the clinical level, you come to appreciate the importance of it.”</i>[<span style='color:#FF6600'>6</span>] </font></span></div> <div class="MsoNormal"><span lang=EN-NZ><font color="#000000">Unfortunately <i>“most hospitals and health systems don’t understand how much at risk they are”</i> [<span style='color:#FF6600'>7</span>]. </font></span></div> <div class="MsoNormal"><span lang=EN-NZ><font color="#000000">Global security principles for health information systems do not exist because nobody owns or regulates the Internet.
