Abstract

Nowadays, the collection of biometric information in commercial public places has become increasingly common. However, the potential legality issues have raised widespread public concerns about the security of personal information. This study focuses on the common problems in the collection of biometric information in commercial public places in China, such as unclear collection purposes, overly broad collection scopes, and insufficient notifications. Based on the Personal Information Protection Law, it proposes solutions such as improving laws and regulations, strengthening supervision, and enhancing merchants' awareness of compliance, to offer theoretical support and practical guidance for the legal development of biometric information collection in commercial public places. The research results aim to provide guidance for the compliance of information collection by enterprises and ensure the security of citizens' personal information rights and interests, promoting the rule of law in the digital society.
