In Episode 275 of the Data Diva Talks Privacy Podcast, Debbie Reynolds, the Data Diva, speaks with personal data privacy consultant Toin Berry about how personal data is collected, combined, inferred, and reused in ways that can significantly affect individuals without their awareness. The conversation focuses on how modern data ecosystems operate beyond direct data collection, emphasizing how inference and aggregation can shape outcomes for people in ways that are difficult to see and even harder to challenge.

Throughout the episode, Debbie and Toin explore how personal data moves through complex networks that include platforms, data brokers, analytics firms, and secondary users. They discuss how information collected in one context can be repurposed in another, how inferred attributes can be treated as facts, and how predictive models can influence decisions about individuals in employment, housing, access to services, and social standing. The discussion also addresses how these practices affect autonomy and agency, particularly when individuals are unaware that profiles are being created about them based on behavioral signals rather than explicit disclosures.

The conversation further examines the limits of commonly promoted privacy controls, such as deletion requests and consent mechanisms, when data has already been copied, enriched, or redistributed across multiple systems. Debbie and Toin talk about the role of data brokers, the recycling of personal data, and the challenges individuals face when trying to understand where their data travels and how it is ultimately used. They also compare approaches to privacy protection in different jurisdictions, including perspectives shaped by European data protection frameworks and U.S. sector based models, highlighting how cultural and regulatory differences influence expectations and outcomes.

This episode also emphasizes the importance of education and data literacy in privacy conversations. Rather than focusing on fear or alarm, Debbie and Toin discuss the need for clearer explanations of how data-driven systems work, how inferences are generated, and what meaningful prevention looks like in practice. The discussion reinforces the idea that privacy is fundamentally about human impact, agency, and long-term consequences, and that understanding data use is essential for protecting people in increasingly complex digital environments.

Episode 274 – Liz MacPherson, Deputy Privacy Commissioner, Office of the Privacy Commissioner, New Zealand

In Episode 274 of The Data Diva Talks Privacy Podcast, Debbie Reynolds, The Data Diva, talks with Liz MacPherson, Deputy Privacy Commissioner at the Office of the Privacy Commissioner of New Zealand, about how privacy functions as a critical guardrail for innovation rather than a barrier to progress. The discussion focuses on New Zealand’s purpose and context-based privacy framework and why strong privacy foundations enable faster, safer, and more trustworthy data use across government and industry.

The conversation explores a landmark case involving the use of facial recognition technology in supermarkets, where regulators, businesses, and independent evaluators worked together to test effectiveness, necessity, and proportionality before deployment. Debbie and Liz unpack why biometric data demands heightened scrutiny, how privacy impact assessments and real-world trials can reduce risk, and why facial recognition is not a plug-and-play technology. They also discuss the importance of human oversight, data quality, access controls, transparency to the public, and the risks of bias and misidentification when systems are poorly governed.

Debbie and Liz also examine New Zealand’s Biometric Processing Privacy Code and its role in setting clear thresholds for biometric use, including limits on categorization and inference. The episode highlights why data retention is one of the most overlooked sources of organizational risk, how unnecessary data creates downstream harm, and why treating personal information as a treasure rather than an asset to be exploited builds long-term trust. Liz emphasizes that organizations succeed when they place people at the center of data decisions and design privacy as part of the full information lifecycle.
