Q: What is online tracking?

A: Website operators/owners often collect information regarding their users' online interaction with the websites. Information such as user's identity, display and/or language preference, web pages visited, items purchased, and transactions performed may be collected and recorded.

Q: What are the main reasons that online behavioural tracking may be a concern for website users?

A: The reasons are:

  • Website users' information or browsing habits are often collected by the website operators/owners without website users' knowledge or consent;
  • Website users' information or browsing habits may even be collected by a third party without website users' knowledge or consent;
  • The collected information may be transferred to other parties by the website operators/owners or the third party without website users' knowledge or consent;
  • Information about a website user collected from one website may be combined with information collected from other websites or sources about that user, thus building his/her profile without his/her knowledge;
  • The purpose of collecting the information is not made clear to the website users. Even if this has been made clear, website users are not offered the option to opt out of the use.

Q: What are the recommended practices to organisations on using cookies?

A: Where cookies are used to collect behavioural information, the following additional best practices are recommended:

  • To pre-set a reasonable expiry date for cookies;
  • To encrypt the contents of cookies whenever appropriate; and
  • Not to deploy techniques such as Flash/zombie/super cookies that ignore browser settings on cookies unless organisations can offer an option to website users to disable or reject such cookies.

Data Protection Principle 6 - Access to personal data

A data subject submitted a request to Organisation B for accessing his personal data originated from Organisation A

The Complaint

With the consent of the complainant, Organisation A provided a copy of a report in relation to the complainant to Organisation B. The complainant later submitted a data access request to Organisation B for accessing the report. However, in the written reply of Organisation B they only stated that the report was not composed by them and suggested the complainant to request the same from Organisation A. The complainant hence complained to this office against Organisation B for not complying with his data access request.

Outcome

Section 19(1) of the Personal Data (Privacy) Ordinance (the Ordinance) requires a data user to comply with a data access request within 40 days after receiving it, unless there is a ground of refusal permissible under section 20 of the Ordinance. Under section 2(1) of the Ordinance, “data user” means a person who controls the collection, holding, processing or use of the personal data.

According to sections 20(3)(d) and 21(1)(c) of the Ordinance, if a data user has imposed restriction on another data user on further disclosure when personal data was transferred from the first-mentioned “data user” to the second-mentioned “data user” in the first place, the second-mentioned “data user” may use this as a reason to refuse compliance with a data subject’s data access request, as long as the second-mentioned “data user” has provided the name and address of the first-mentioned “data user” to the data subject.

In response to our inquiries, Organisation B confirmed that they were neither an agent nor a data processor appointed by Organisation A (i.e. Organisation B is an independent “data user”). Organisation B further confirmed that no restriction on further disclosure was imposed on them when they obtained the report from Organisation A.

Not being the composer of the report is not a reason permissible under the Ordinance to refuse compliance with a data access request. As long as no restriction of disclosure was imposed on Organisation B and there is no other reason of refusal permissible under the Ordinance, Organisation B as a “data user” of the report in question has a duty to provide the complainant with a copy of his personal data contained therein.

This office explained relevant provisions under the Ordinance to Organisation B, which had subsequently complied with the complainant’s data access request.
