National bodies that are members of ISO or IEC participate in the

20、 development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-gov

21、ernmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IE

22、C Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives). Attention is drawn to the possibili

ISO/IEC 2017 All rights reserved v BS ISO/IEC 29134:2017 ISO/IEC 29134:2017(E) Introduction A privacy impact assessment (PIA) is an instrument for assessing the potential impacts on privacy of a process, information system, programme, software module

27、, device or other initiative which processes personally identifiable information (PII) and, in consultation with stakeholders, for taking actions as necessary in order to treat privacy risk. A PIA report may include documentation about measures taken for risk treatment, for example, measures arising

28、 from the use of the information security management system (ISMS) in ISO/IEC 27001. A PIA is more than a tool: it is a process that begins at the earliest possible stages of an initiative, when there are still opportunities to influence its outcome and thereby ensure privacy by design. It is a proc

29、ess that continues until, and even after, the project has been deployed. Initiatives vary substantially in scale and impact. Objectives falling under the heading of “privacy” will depend on culture, societal expectations and jurisdiction. This document is intended to provide scalable guidance that c

30、an be applied to all initiatives. Since guidance specific to all circumstances cannot be prescriptive, the guidance in this document should be interpreted with respect to individual circumstance. A PII controller may have a responsibility to conduct a PIA and may request a PII processor to assist in

31、 doing this, acting on the PII controllers behalf. A PII processor or a supplier may also wish to conduct their own PIA. A suppliers PIA information is especially relevant when digitally connected devices are part of the information system, application or process being assessed. It may be necessary

32、for suppliers of such devices to provide privacy-relevant design information to those undertaking the PIA. When the provider of digital devices is unskilled in and not resourced for PIAs, for example: a small retailer, or a small and medium-sized enterprise (SME) using digitally connected devices in

33、 the course of its normal business operations, then, in order to enable it to undertake minimal PIA activity, the device supplier may be called upon to provide a great deal of privacy information and undertake its own PIA with respect to the expected PII principal/SME context for the equipment they

34、supply. A PIA is typically conducted by an organization that takes its responsibility seriously and treats PII principals adequately. In some jurisdictions, a PIA may be necessary to meet legal and regulatory requirements. This document is intended to be used when the privacy impact on PII principal

35、s includes consideration of processes, information systems or programmes, where: the responsibility for the implementation and/or delivery of the process, information system or programme is shared with other organizations and it should be ensured that each organization properly addresses the identif

36、ied risks; an organization is performing privacy risk management as part of its overall risk management effort while preparing for the implementation or improvement of its ISMS (established in accordance with ISO/IEC 27001 or equivalent management system); or an organization is performing privacy ri

37、sk management as an independent function; an organization (e.g. government) is undertaking an initiative (e.g. a public-private-partnership programme) in which the future PII controller organization is not known yet, with the result that the treatment plan could not get implemented directly and, the

38、refore, this treatment plan should become part of corresponding legislation, regulation or the contract instead; the organization wants to act responsible towards the PII principals.vi ISO/IEC 2017 All rights reserved BS ISO/IEC 29134:2017 ISO/IEC 29134:2017(E) Introduction A privacy impact assessme
