Fog Data Science is a controversial data broker that sells location data from mobile apps to law enforcement agencies. The company claims to respect user privacy and not collect any personally identifiable information (PII), but its practices have been criticized by privacy advocates.

Fog Data Science purchases raw geolocation data from popular and less popular smartphone and tablet applications. These apps continuously gather your device’s location information and sell that data to data brokers. Fog Data Science then aggregates this data into a database of billions of geolocation signals.

Fog Data Science sells subscriptions to a service called Fog Reveal, which lets law enforcement lookup location data in the database. Law enforcement can use this data to track individuals without requiring a search warrant.

Fog Data Science has been used by local, state, and federal law enforcement agencies in the United States since at least 2018. In 2022, the Electronic Frontier Foundation (EFF) revealed that Fog Data Science had 40 contracts with “nearly two dozen agencies,” including the Dallas Police Department and the Rockingham County, North Carolina sheriff’s office.

The EFF has criticized Fog Data Science for its privacy practices. The organization argues that Fog Data Science’s data collection practices are “unnecessarily invasive” and that the company’s data is being used by law enforcement to track people without their knowledge or consent.

In response to the EFF’s criticism, Fog Data Science has said that its data collection practices are legal and that the company is committed to protecting user privacy. The company also says that its data is only used by law enforcement for legitimate purposes.

Despite Fog Data Science’s claims, there are concerns about the potential for abuse of its data. For example, law enforcement could use Fog Data Science data to track protesters or people who are suspected of engaging in other lawful activities.

How to Protect Yourself from Fog Data Science

The best way to protect yourself from Fog Data Science is to limit the amount of location data that you share with apps. You can do this by revoking location permissions to any apps that you do not completely trust. You can also turn off location services at the operating system level.

Here are some additional tips for protecting your privacy:

  • Be careful about which apps you install on your phone. Only install apps from trusted sources.
  • Read the privacy policies of apps before you install them.
  • Review the permissions that apps are asking for and only grant permissions to apps that you need them to have.
  • Keep your phone’s software up to date. Software updates often include security patches that can help protect your device from malware and other threats.

From understanding the concept of Fog Data Science to ensuring data security, we’ll cover it all. So, whether you’re a beginner or an experienced professional, get ready to enhance your knowledge and skills in this exciting domain.
