17、odies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizati
18、ons, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the
19、 ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of t
20、he member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 17090-2 was prepared by Technical Committee ISO/TC 215, Health i
21、nformatics. This first edition cancels and replaces the Technical Specification (ISO/TS 17090-2:2002), which has been revised and brought to the status of International Standard. ISO 17090 consists of the following parts, under the general title Health informatics Public key infrastructure: Part 1:

23、duction The healthcare industry is faced with the challenge of reducing costs by moving from paper-based processes to automated electronic processes. New models of healthcare delivery are emphasizing the need for patient information to be shared among a growing number of specialist healthcare provid
24、ers and across traditional organizational boundaries. Healthcare information concerning individual citizens is commonly interchanged by means of electronic mail, remote database access, electronic data interchange and other applications. The Internet provides a highly cost-effective and accessible m
25、eans of interchanging information, but it is also an insecure vehicle that demands additional measures be taken to maintain the privacy and confidentiality of information. Threats to the security of health information through unauthorized access (either inadvertent or deliberate) are increasing. It
26、is essential to have available to the healthcare system reliable information security services that minimize the risk of unauthorized access. How does the healthcare industry provide appropriate protection for the data conveyed across the Internet in a practical, cost-effective way? Public key infra
27、structure (PKI) and digital certificate technology seek to address this challenge. The proper deployment of digital certificates requires a blend of technology, policy and administrative processes that enable the exchange of sensitive data in an unsecured environment by the use of “public key crypto
28、graphy” to protect information in transit and “certificates” to confirm the identity of a person or entity. In healthcare environments, this technology uses authentication, encipherment and digital signatures to facilitate confidential access to, and movement of, individual health records to meet bo
29、th clinical and administrative needs. The services offered by the deployment of digital certificates (including encipherment, information integrity and digital signatures) are able to address many of these security issues. This is especially the case if digital certificates are used in conjunction w
30、ith an accredited information security standard. Many individual organizations around the world have started to use digital certificates for this purpose. Interoperability of digital certificate technology and supporting policies, procedures and practices is of fundamental importance if information
31、is to be exchanged between organizations and between jurisdictions in support of healthcare applications (for example between a hospital and a community physician working with the same patient). Achieving interoperability between different digital certificate implementations requires the establishme
32、nt of a framework of trust, under which parties responsible for protecting an individuals information rights may rely on the policies and practices and, by extension, the validity of digital certificates issued by other established authorities. Many countries are deploying digital certificates to su
33、pport secure communications within their national boundaries. Inconsistencies will arise in policies and procedures between the certification authorities (CAs) and the registration authorities (RAs) of different countries if standards development activity is restricted to within national boundaries.
34、 Digital certificate technology is still evolving in certain aspects that are not specific to healthcare. Important standardization efforts and, in some cases, supporting legislation are ongoing. On the other hand, healthcare providers in many countries are already using or planning to use digital c
35、ertificates. ISO 17090 seeks to address the need for guidance of these rapid international developments. ISO 17090 describes the common technical, operational and policy requirements that need to be addressed to enable digital certificates to be used in protecting the exchange of healthcare informat
36、ion within a single domain, between domains and across jurisdictional boundaries. Its purpose is to create a platform for global interoperability. It specifically supports digital certificate-enabled communication across borders, but could also provide guidance for the national or regional deploymen
37、t of digital certificates in healthcare. The Internet SANS 17090-2:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .ISO 17090-2:2008(E) vi ISO 2008 All rights reservedis increasingly used as the vehicle of choice to support the movement of
38、 healthcare data between healthcare organizations and is the only realistic choice for cross-border communication in this sector. ISO 17090 should be approached as a whole, with the three parts all making a contribution to defining how digital certificates can be used to provide security services in
39、 the health industry, including authentication, confidentiality, data integrity and the technical capacity to support the quality of digital signature. ISO 17090-1 defines the basic concepts underlying the use of digital certificates in healthcare and provides a scheme of interoperability requiremen
40、ts to establish digital certificate-enabled secure communication of health information. This part of ISO 17090 provides healthcare-specific profiles of digital certificates based on the international standard X.509 and the profile of this, specified in IETF/RFC 3280 for different types of certificat
41、es. ISO 17090-3 deals with management issues involved in implementing and using digital certificates in healthcare. It defines a structure and minimum requirements for certificate policies (CPs) and a structure for associated certification practice statements. ISO 17090-3 is based on the recommendat
42、ions of the informational IETF/RFC 3647, and identifies the principles needed in a healthcare security policy for cross border communication. It also defines the minimum levels of security required, concentrating on the aspects unique to healthcare. Comments on the content of this document, as well
