Ohio Senate Passes Bill Criminalizing AI-Generated Child Abuse Material and Mandating AI Watermarks

Ohio Senate unanimously passed Senate Bill 163 on May 20, criminalizing AI-generated child sexual abuse material and requiring a watermark on every piece of AI-created content.

Ohio has lagged behind many states in treating AI-produced child exploitation as a crime. The legislation follows a national trend where lawmakers grapple with the misuse of generative AI for illicit purposes. Ohio's move comes after Governor Mike DeWine urged the legislature to act during his final State of the State address.

The bill makes it illegal to create, transfer, or possess any sexually oriented depiction of a minor that was produced with artificial intelligence. Violators could face felony charges, fines, and mandatory registration as sex offenders under existing state statutes.

It also requires every generative AI output to carry a visible or machine-readable watermark that flags the content as AI-generated. The watermark must be embedded in a way that survives common file conversions and platform uploads, ensuring traceability.

Sen. Terry Johnson, a co-sponsor, warned that AI's growing sophistication lets anybody with a computer cause harm. He cited a personal story of his mother being scammed by a deepfake pretending to be her granddaughter, illustrating how the technology can be weaponized beyond child exploitation.

If signed into law, Ohio will join a growing list of states that penalize AI-based child abuse material, potentially deterring offenders and giving prosecutors a clearer statute. Legal experts say the new felony provisions could streamline prosecutions that currently rely on broader obscenity laws.

The watermark rule could help platforms detect and remove synthetic content, though enforcement will depend on technical standards and cooperation from AI developers. State officials plan to work with the Ohio Attorney General's office to create a compliance checklist for companies operating within the state.

Critics may raise concerns about free speech and the feasibility of watermarking all AI outputs, issues likely to be debated as the bill moves forward. Some advocacy groups argue that overly broad watermarking requirements could impede legitimate artistic or research uses of generative AI.

Watch for the Ohio House to consider the bill, any amendments from tech industry groups, and whether Governor Mike DeWine signs it into law. Analysts will also monitor potential legal challenges that could arise once the law takes effect.
