The bill amends Chapter 6 of the General Laws to implement recommendations from a special commission on facial recognition technology. It introduces a new section 220, which defines key terms such as "biometric surveillance technology," "facial recognition," and "public agency." The bill prohibits law enforcement agencies and officers from acquiring, possessing, or using biometric surveillance technology without express authorization, and it establishes strict guidelines for the use of facial recognition technology. Exceptions are made for the registrar of motor vehicles and the department of state police under specific circumstances, such as verifying identities or executing warrants.

Additionally, the bill mandates transparency and accountability measures, requiring law enforcement to document and report facial recognition searches, including the rationale for emergency searches and the demographic data of individuals involved. It also prohibits the use of biometric surveillance systems to infer emotions or analyze moving images, while allowing limited use of personal devices for user authentication. The bill aims to regulate the use of facial recognition technology to protect individual rights while enabling law enforcement to utilize it under controlled conditions.
