How does the addition of data due to IoT create privacy issues?

When more data is generated by IoT, the risk isn’t just that there’s more information, but that pieces from different datasets can be linked together to reveal who someone is. Even if each dataset is anonymized, combining them can expose identity through patterns, timestamps, locations, device IDs, or behavior. This re-identification risk—called data fusion—means that the addition of IoT data increases privacy threats because it makes it easier to connect data points back to a real person. IoT devices produce continuous streams of granular data about when, where, and how people use things, so linking these streams with other data sources can uncover sensitive details. That’s why this option best captures the privacy issue: de-identified data can become identifying when merged with other datasets. The other concerns—data processing backlogs, more chances for leaks just due to volume, or securing wireless channels—are relevant but don’t address the fundamental way privacy can be compromised through data fusion.
