From object obfuscation to contextually-dependent identification: enhancing automated privacy protection in street-level image platforms (SLIPs)

Figures & data

Table 1. Overview of object obfuscation by mode of failure.

Mode of failure	Description of object obfuscation issue
False Negatives	System fails to accurately detect and blur features of an object before images are made publicly available.
False Positives	System detects and pixelates an object which is not required to be blurred.
The ‘Streisand Effect’	System blurs an object, and the act of blurring paradoxically draws attention to the object which is intended to be concealed.
Contextual Identification	System accurately detects and blurs features, but the object is identifiable from contextual indicators.
