Your how-to: Utilising data anonymisation techniques to protect employee privacy related to mental health
Data anonymisation is a process of protecting an individual's privacy by removing personally identifiable information or altering it in a way that it cannot be linked back to them. When utilised in an organisational setting, it can provide valuable insights about employee mental health trends without compromising individual confidentiality, promoting a culture of trust and inclusivity.
For mental health data, this could include masking details such as names, roles, or departments which may be used to identify an individual, but retaining non-identifiable data around areas such as stress patterns, absenteeism due to mental health, or use of wellbeing support services. These insights can be used to inform your organisational strategies related to mental health without placing anyone's privacy at risk.
In the context of Australia, the Privacy Act 1988 is a key legislation that regulates how personal data should be handled. It necessitates that organisations must not disclose any personal information unless the individual has given consent, or it is required for law enforcement. Adhering to this law whilst utilising data anonymisation techniques for evaluating mental health within your organisation can uphold your employees' right to privacy and fulfil regulatory requirements.
Step by step instructions
Understand Legal Framework: Understand the legal obligations that your organisation is under to protect personal data. This includes understanding the Australian Privacy Act 1988 to ensure that any personal information is kept confidential unless explicit consent is given or it is lawfully required.
Separate Identifiable from Non-Identifiable Data: Distinguish what aspects of the data are personally identifiable (names, roles, departments etc.) and what aspects can be categorised as anonymous (trends in stress patterns, mental health-related absenteeism, use of wellbeing services etc.).
Implement Data Review & Audit Processes: Set up a system to review and audit the anonymised data. This is to make sure that the anonymisation remains effective and that original data is not accidentally included.
Regularly Update and Review the Process: Ensure your data anonymisation techniques remain effective and compliant with evolving privacy laws and regulations by undertaking regular reviews and updates.
Establish the Scope of Data Collection: Identify and define the mental health data that your organisation will be collecting. This could range from data from mental health surveys, interviews, medical leave records, programmes attended and/or employee assistance program usage.
Apply Anonymisation Techniques: Once all personally identifiable data has been separated, apply anonymisation techniques to ensure the non-identifiable information can't be traced back to the individual. Techniques can range from data masking, pseudonymisation, or generalisation. The best technique largely depends on the nature of the data and your specific organisational needs.
Develop Policies and Procedures: Formulate a data protection policy outlining your organisation's approach to data handling and anonymisation. Make sure these processes comply with local laws and are transparent to the employees.
Reflect and Breathe: This step can be challenging, so it's important to take a moment to breathe and reflect. Pause to consider the progress made, the obstacles encountered, and the lessons learned. This reflection will not only help in gaining clarity but also in maintaining a balanced perspective, allowing for thoughtful and deliberate decision-making moving forward.

Pitfalls to avoid
Data masking is a common method used in anonymisation but when applied excessively, it can distort the data to the point where it loses its utility for analysis.
It is essential to thoroughly anonymise the data to ensure no identifiable information can be drawn. Failure to fully conceal sensitive information can lead to a breach of individual privacy.
Businesses must comply with the Australia's Privacy Act 1988, which sets out principles for the collection, security, quality, and disclosure of personal information. Ignoring these requirements can bring legal repercussions.
Employees involved in data handling and management should be well trained in anonymisation techniques. Without appropriate knowledge, they might misuse information or not properly anonymise it, breaking privacy laws.
The process of data anonymisation is not a one-off task, but an ongoing process that needs to adhere to changing legal, technical, and business requirements.
By not identifying and evaluating the potential threats to data privacy, you may expose your employees' sensitive information. You must adopt a risk-assessment approach towards data anonymisation.
