The development of a facial recognition system based on deep learning can indeed improve the recognition efficiency and accuracy, but it must strictly abide by national laws, regulations and ethical standards to ensure that the application of technology does not infringe on personal privacy and other legitimate rights and interests. The Chinese government attaches great importance to the protection of citizens' personal information.It has promulgated the "Personal Information Protection Law" and other relevant laws, which have put forward strict requirements for the collection, storage, and use of personal information. The research and development and application of any technology should be carried out within the legal framework to serve the public interests and maintain national security and social stability. We support scientific and technological innovation, but resolutely oppose any behavior that may endanger national security and citizens' rights and interests.
