What is snapchat facial recognition fbi?

As an AI language model, I do not have access to current information, but as of my last training data, there were concerns about the FBI using Snapchat's facial recognition technology for surveillance and monitoring purposes. In 2016, a report revealed that the FBI had used Snapchat's facial recognition algorithms to identify and track suspects in criminal investigations. However, Snapchat clarified that its facial recognition technology is only used for specific features within the app, such as the filters and lenses. The company also stated that it has rules in place to protect user privacy and that it requires a valid legal request for user information from law enforcement.
