According to a study, Meta Platforms and TikTok capture hashed personal information from web forms even when the user does not submit the form or grant authorization.

According to researchers from KU Leuven, Radboud University, and the University of Lausanne, both Meta Pixel and TikTok Pixel offer a feature called Automatic Advanced Matching (AAM) that captures hashed personal IDs from web forms in an automated manner.

Pixels are a type of code that allows platforms to track visitor behaviour. This data can be used to serve adverts to consumers based on their interests, preferences, and online behaviour. It can also track the effectiveness of advertisements.

The hashed personal identifiers are then used to target adverts on the platforms in question, track conversions, and develop new custom audiences.
