IoT privacy risk grows as many small observations accumulate into a detailed picture
Individually, none of the readings look sensitive. Together they describe your life in detail.
When the lights go on, when the kettle boils, when the door opens, when the room is occupied. Each data point is trivial and the aggregate reveals occupancy, routine, sleep patterns and household size. Privacy assessments that consider each sensor separately consistently miss what the combination produces.
