PCPD - Installation of CCTV in Public Transportation Vehicles

Installation of CCTV in Public Transportation Vehicles

1.    The Privacy Commissioner for Personal Data (the Commissioner) Mr. Roderick B. Woo. writes to the MTR Corporation today (15 January) urging it to strictly comply with the Personal Data (Privacy) Ordinance to safeguard the personal data privacy of the public when closed-circuit televisions (CCTV) are installed. According to the media, MTR “intends to install CCTV in train compartments for security purposes and provision of assistance to passengers”.

2.    “When using monitoring and recording devices in public place, it is our view that a proper balance should be struck between the protection of public interests and personal data privacy. Data users should handle the issue in a fair and transparent manner giving due regards to the rights of personal data privacy.” Mr. Woo said.

3.    According to the Personal Data (Privacy) Ordinance (the Ordinance), “personal data” are any data relating to a living individual, which are stored in recorded form making access to or processing practicable and from which it is practicable for the identity of the individual to be directly or indirectly ascertained from it. Generally speaking, to constitute an act of collection of personal data by the data user, there should be compilation of information about an individual, whose identity must have been identified by the data user, or the data user intends or seeks to identify the identity of the individual.

4.    Organizations can install monitoring and recording systems only if it is necessary for fulfilling their legitimate functions or activities, such as for security reasons, the monitoring of illegal acts (e.g. throwing objects from height), etc. Before an organization installs a monitoring and recording system, it is suggested that it should establish the collection purposes, evaluate the risks of monitoring, and consider if there is any other substitute that is less privacy intrusive in order to strike a balance between the protection of privacy rights of individuals and the smooth operation of the organizations.

5.    In general, if a monitoring and recording system is installed in a public place merely for the sake of security, it may not constitute collection of personal data (unless the data of a certain or some particular individuals are collected) and it may not be subject to the Ordinance. However, collection of personal data may take place under some special circumstances. For example, after a special incident has happened, the authority concerned may need to review the video records for the purpose of ascertaining the identity of the individuals involved in the incident and it may then amount to collection of personal data. Therefore, organizations which intend to install monitoring and recording systems should, at least, post a notice in a prominent position near the installation, stating that the area is being monitored, the purposes of monitoring, as well as the ways of handling the records.

6.    When an organization has decided to install a monitoring and recording system, it is suggested that in the interest of transparency it should post a notice in a prominent position near the installation (the words should be clear and noticeable) so that sufficient notice is drawn to the public or the people affected hat their activities may be recorded and the reasons for collection of their personal data. The organizations concerned are suggested to formulate policies on video monitoring, and the persons who can access and view the contents of the tapes. Moreover, the organizations should also prescribe the retention period of the tapes and delete the data in the tapes accordingly, and steps shall also be taken to ensure that the tapes are securely kept.
