So your organisation creates, holds, manages and disseminates data. Did you know that all of those actions also generate metadata, which can hide personal information? At a basic level, metadata is data that describes other data. In the context of digital files, metadata can include information such as the date and time a file was created, the location where it was created, and details about the device or software used to create it. Metadata is important for privacy because it can reveal information about the content and context of a file, even if the file itself does not contain any identifiable information. For example, metadata associated with a photo taken on a smartphone may reveal the location where the photo was taken, even if the photo itself does not show any identifiable landmarks. To protect privacy, it's important to be aware of what metadata is being generated by different types of files, and to take steps to limit or remove metadata as needed. While metadata might not directly reveal the content of the data, it can still contain valuable information that impacts privacy. Here's how metadata is relevant to privacy management: Identifying Personal Information: Metadata can help determine whether certain data falls under the definition of personal information. Metadata can reveal details about the data's source, creation, and intended use, aiding in the identification of personal information. Assessing Data Sensitivity: Metadata provides insights into the sensitivity or potential risks associated with the data. Understanding the metadata helps assess the privacy implications of different datasets and implement appropriate safeguards, controls, or consent mechanisms. Consent and Purpose Limitation: Metadata assists in ensuring compliance with the principles of consent and purpose limitation. It helps clarify the intended purposes for which personal information was collected and the scope of consent obtained from individuals. Metadata can also help track and monitor data usage to ensure it remains within the defined purpose limits. Data Retention and Disposal: Metadata aids in effective data management, including retention and disposal practices. It helps track data lifecycle information, such as creation dates, access logs, and retention periods, enabling organisations to adhere to obligations under the Privacy Act regarding data retention and secure disposal of personal information. Data Access and Security: Metadata provides insights into who accessed the data, when, and under what circumstances. It assists in monitoring data access, detecting unauthorised access attempts, and ensuring appropriate security measures are in place to protect personal information. Data Breach Management: Metadata is valuable in managing data breaches and complying with breach notification requirements. It helps in identifying the scope and impact of a breach, understanding which personal information was compromised, and evaluating the potential harm to individuals. This information is crucial for determining the appropriate actions to be taken under the Privacy Act, such as notifying affected individuals and the Privacy Commissioner. By recognising the significance of metadata in privacy management, organisations can proactively consider metadata-related implications when handling personal information, ensuring compliance with the New Zealand Privacy Act. It reinforces the need to implement privacy-aware practices across data lifecycle, including metadata handling, to protect individuals' privacy rights effectively.

I'm sure everyone that has used the internet in the last few years has had one of those pop-ups asking what kind of cookies you want enabled. These pop-ups can be confusing and in my experience, seem keen to ensure you enable all cookies rather than actually enabling only the necessary ones. So what are you agreeing to exactly when you enable all the cookies? Cookies are small text files that are stored on your computer or mobile device when you visit a website. They can be used to remember your preferences and login information, track your activity on the site, and deliver personalised advertising. While cookies can be useful for improving the user experience, they can also raise privacy concerns. For example, cookies can be used to track your browsing activity across multiple sites, which can be used to build a profile of your interests and behavior. It's important to understand how cookies are being used on the sites you visit, and to make informed choices about what information you are willing to share. Most web browsers allow you to control which cookies are stored on your device, and you can also use tools like browser extensions and privacy-focused search engines to limit tracking and protect your privacy online. Some cookies are creepier than others. Take a look at some common types of cookies: Session Cookies: These cookies are temporary and are stored only during a user's browsing session. They are deleted as soon as the session ends or the browser is closed. Session cookies help maintain user session information and enable essential website functionalities. Persistent Cookies: Unlike session cookies, persistent cookies remain on a user's device even after the browsing session ends. They have an expiration date set by the website, and they are used to remember user preferences and settings for future visits. First-party Cookies: First-party cookies are set by the website domain the user is visiting. They enable the website to remember information about the user, such as language preferences, shopping cart contents, or login credentials. First-party cookies are generally considered less invasive to privacy. Third-party Cookies: These cookies are set by domains other than the website the user is visiting. They are typically used for advertising, tracking user behavior across different websites, and delivering targeted ads. Third-party cookies can raise privacy concerns as they allow third-party entities to collect and track user information across multiple websites. Strictly Necessary Cookies: These cookies are essential for the functioning of a website. They enable basic features like page navigation, access to secure areas, and form submission. Strictly necessary cookies do not require user consent as they are necessary for the website to provide requested services. Analytical or Performance Cookies: Analytical cookies collect data about how users interact with a website, including pages visited, time spent, and error messages. The information gathered helps website owners understand and improve the performance and user experience. Advertising Cookies: Advertising cookies are used to track user behavior and interests to deliver targeted ads. They collect information about browsing habits, visited websites, and clicked ads. Advertisers use this data to personalise advertisements and measure their effectiveness. One cookie example you might be familiar with is the google analytics. Google has a specific cookie called "DV" that is used by Google to collect information about user behavior on websites that use Google services, such as Google Analytics. This is a bit creepy when you consider that so many websites (maybe up to 86% of them) use Google analytics! This means your behaviour across hundreds, thousands maybe millions of websites can be tracked all by Google (and then probably sold off to other companies)! If you're not already creeped out, check out this article by the Electronic Frontier Foundation .

So this is interesting! Did you know that personal information that can no longer be connected to a person is effectively "disposed of"? According to the New Zealand Privacy Act 2020, personal information can be considered disposed of if it is effectively de-identified. De-identification is a process that removes or modifies identifiable elements from personal information to ensure that the remaining data no longer relates to an identifiable individual. When personal information is de-identified, it means that the data has been altered or transformed in a way that makes it practically impossible to identify the individuals to whom it belongs. The Privacy Act recognises de-identified information as no longer falling under the scope of "personal information" because the risk of identifying individuals is significantly reduced. Isn't that cool? To ensure that personal information is properly de-identified, the Privacy Act provides guidance on key principles that need to be followed. These principles include: Irreversibility: The de-identification process should be irreversible. Once the personal information is de-identified, it should not be possible to re-identify individuals using the remaining data alone or in combination with other information. Reasonable means: De-identification should be carried out using reasonable means and methods appropriate to the nature of the personal information and the purpose for which it will be used. Reasonable likelihood of re-identification: The likelihood of re-identifying individuals from the de-identified information, considering the available or reasonably likely resources and techniques, should be low. By effectively de-identifying personal information, organisations can reduce the privacy risks associated with data handling. De-identified information can be used for research, statistical analysis, or other purposes without violating privacy laws, as long as the de-identification process is conducted in accordance with the principles outlined in the Privacy Act. Remember, if you are handling personal information and considering de-identification, it's important to refer to the specific provisions and guidance provided by the New Zealand Privacy Act and seek legal advice if needed to ensure compliance with the law. There is a spectrum of de-identification from pseudonymisation to anonymisation. Pseudonymisation is the process of replacing identifying information with a pseudonym or alias. For example, replacing someone's name with a unique ID number. Pseudonymisation can help protect personal information by making it more difficult to identify individuals. Replacing identifying information with pseudonyms may be considered de-identification *if* there is no longer any record of the original identity. In that way it would be similar to anonymisation, which is the process of removing all identifying information from data so that it cannot be linked back to an individual, even with additional information. For example, removing all identifying details from a medical study dataset. Anonymisation can help protect personal information while still allowing the data to be used for research or other purposes. 

Data mapping is one of those new buzzwords that's been rattling around the information community for a while now. At its most basic level, data mapping is figuring out where your information is and where it goes. In order to map your data, you'll have to take a close look at all the personal information that your organisation collects, processes, and stores. This might include things like customer names and addresses, employee contact details, financial information, and more. The idea is to create a comprehensive picture of how personal information flows through your organisation, from the moment it's collected to the moment it's deleted or destroyed. During the data mapping process, it might be useful to create a visual map or diagram that shows all the different systems, applications, and databases that handle personal information. You might also look at things like who has access to personal information, how long it's kept for, and what security measures are in place to protect it. Why is this important? Well, understanding how personal information is handled is essential for ensuring that it's being protected properly. It can also help identify any potential risks or vulnerabilities, such as systems that might be more prone to security breaches, or areas where personal information might be accidentally disclosed. Overall, data mapping is a valuable tool for any organisation that handles personal information. By taking the time to map out all the data you collect and process, you can better understand privacy risks and take steps to ensure that personal information is being handled in a responsible and secure way.

Privacy breaches happen all the time to organisations all over the world. We've had some notable ones here in NZ which provide some good 'what not to do' examples, but chances are, your organisation will experience at least a few in its lifetime! They key thing is how you manage them. Before we jump into managing a breach, it's useful to explain the difference between an incident and a breach. A privacy incident refers to any situation where there is a potential unauthorised access, use, or disclosure of personal information. This might be an unsecured system or an HR file left on a copier. On the other hand, a privacy breach occurs when there is an actual unauthorised access, use, or disclosure of personal information. This can happen if a hacker breaks into a database, if an employee accidentally sends an email to the wrong person, or if a physical document goes missing. Basically, any time personal information is exposed in a way that wasn't supposed to happen, it's considered a privacy breach. This is a big deal because personal information is sensitive and can be used for things like identity theft. If you think there's been a privacy breach, it's important to take action right away to protect people's privacy. To determine if a privacy incident is a breach under the New Zealand Privacy Act, you should consider the following factors: Nature of the information: Personal information includes details like names, contact information, financial data, or any other data that identifies an individual. If the incident involves unauthorised access to this kind of information, it raises concerns for a potential breach. Unauthorised access or disclosure: A privacy breach occurs when there is an unauthorised access or disclosure of personal information. If someone gains access to or shares personal information without proper authorization, it could be considered a breach. Likelihood of harm: The Privacy Act considers the potential harm or adverse effects that could result from a privacy breach. If there is a risk of harm to individuals, such as identity theft, financial loss, or reputational damage, it strengthens the case for a breach. Steps taken to mitigate harm: If an organisation takes prompt action to minimise the impact of the incident and protect individuals affected by the privacy incident, it demonstrates commitment to handling the situation responsibly. Reporting obligations: Organisations are required by law to notify the Privacy Commissioner and affected individuals in the event of a privacy breach that could cause serious harm. Compliance with these reporting obligations is an important factor in determining if an incident qualifies as a breach. Breaches can be a really scary time for the victims of the breach and the people who (hopefully unwittingly) caused the breach. This can be magnified if the breach reaches the threshold of being notifiable under the Privacy Act. We can help figure out your threshold and identify whether you need to get the Privacy Commission involved. We're experts at dealing with breaches (we love a little drama in our lives!) and have a strong belief in a no-blame culture, unless the breach is caused by malicious activity of course. If you need some help figuring out whether you're dealing with an incident or a breach or maybe you just need a calming pat on the head, we're here to help!
