U.S. Senate Committee Passes GUARD Act to Advance AI Age Verification Legislation

Senate Committee Pushes AI Age Verification Bill Forward

The U.S. Senate Commerce Committee recently voted to pass the closely watched GUARD Act (Generating Underage AI Restrictions and Defenses Act), which requires artificial intelligence platforms to implement age verification mechanisms aimed at preventing minors from accessing AI services without adequate protections. This legislative development is widely seen as a critical step in U.S. AI regulation.

Core Provisions of the Bill

The GUARD Act has a clear central objective: requiring tech companies that offer generative AI services to deploy effective age verification systems, ensuring that underage users receive appropriate safety protections when using AI products.

Key provisions of the bill include:

• Mandatory Age Verification: AI platforms must verify users' ages before registration or service use to determine whether a user is a minor
• Minor Protection Mechanisms: Platforms must activate additional content filtering and safety measures for underage users
• Clear Platform Accountability: Companies that fail to comply will face corresponding legal liability and penalties
• Privacy and Safety Balance: The bill also requires that the age verification process adhere to fundamental principles of user privacy protection

Legislative Background and Driving Factors

In recent years, the explosive proliferation of generative AI tools such as ChatGPT and Midjourney has significantly lowered the barrier for minors to access AI technology. From deepfake content to inappropriate conversational interactions, the potential harms AI technology may pose to young people have increasingly raised concerns across all sectors of society.

Multiple surveys have shown that large numbers of minors are frequently using various AI tools, while the vast majority of AI platforms currently lack effective age verification measures. Users can bypass restrictions simply by checking a box stating "I am 18 or older" — a protection mechanism so ineffective it has been repeatedly criticized by lawmakers and children's rights organizations.

Previously, multiple U.S. states had already pushed similar age verification legislation in the social media space. The GUARD Act formally extends this regulatory approach to the AI domain, reflecting lawmakers' heightened vigilance toward the risks of emerging technologies.

Reactions and Controversies

The bill's passage received broad bipartisan support — a rarity in today's highly polarized U.S. political environment — demonstrating that protecting minors is an issue with a cross-party consensus.

Child safety advocacy organizations have welcomed the bill, calling it "a belated but necessary step." However, the tech industry and some privacy advocates have raised noteworthy concerns:

• Technical Feasibility: How to achieve reliable age verification without excessive collection of personal information remains a technical challenge
• Privacy Risks: Mandatory age verification could lead platforms to collect more sensitive user data, potentially creating new privacy vulnerabilities
• Impact on Innovation: Overly stringent compliance requirements could increase the operational burden on small and mid-sized AI companies, dampening industry innovation

Global AI Regulation Accelerates

The advancement of the GUARD Act is not an isolated event but an important part of the global wave of AI regulation. The EU's AI Act began phased implementation this year, which also includes strict requirements for high-risk AI systems. The United Kingdom, Australia, and other countries are similarly exploring AI protection legislation targeting minors.

Notably, China has also been at the forefront of AI regulation, having successively issued multiple regulations including the Interim Measures for the Management of Generative Artificial Intelligence Services, which clearly define AI service providers' obligations to protect users.

Looking Ahead

With the GUARD Act having passed at the committee level, the next step is a full Senate floor vote. If it successfully passes both chambers of Congress and is signed by the President, the bill will become the first federal law in the United States specifically addressing age verification on AI platforms.

For the global AI industry, this legislative development sends a clear signal: as technology advances rapidly, protective regulation for vulnerable groups is accelerating. AI companies need to adopt a compliance-first mindset, embedding effective minor protection mechanisms at the product design stage rather than reacting passively under legal pressure.

The legislative exploration of AI safety protections for minors has only just begun. Finding the right balance between protection and innovation will be a long-term challenge that global regulators and the tech industry must face together.
