Recording Law for Voiceprints & Biometric Data in Ohio

Ohio lets you record any conversation you’re part of without telling the other person first. The law says it’s legal to intercept a wire, oral, or electronic communication if you’re a party to it or have the prior consent of one party, as long as you’re not using the recording to commit a crime or fraud. This rule is found in Ohio Revised Code § 2933.52(B)(4). The same section makes unauthorized interception a felony of the fourth degree, and it gives anyone harmed by an illegal recording a private right to sue for damages. The statute’s penalty provision states: “Whoever violates this section is guilty of interception of wire, oral, or electronic communications, a felony of the fourth degree.”

Ohio’s wiretap law only protects conversations that carry a reasonable expectation of privacy. The statute defines an “oral communication” as “an oral communication uttered by a person exhibiting an expectation that the communication is not subject to interception under circumstances justifying that expectation.” Ohio Revised Code § 2933.51(B). If someone speaks loudly in a public place where others can easily overhear, the utterance may not qualify as a protected “oral communication” because it lacks the statutorily required reasonable expectation of privacy. Because no Ohio appellate decision has squarely addressed this exact situation under the current statutory text, the inference that loud public speech likely falls outside “oral communication” follows from the statutory text alone.

You can record your own conversations with police in Ohio under the one-party-consent rule, because you’re a party to the exchange. Ohio Revised Code § 2933.52(B)(4) allows this. However, the Sixth Circuit—where Ohio sits—has not issued a published, binding decision that clearly protects a private citizen’s right to record on-duty police in public. The only relevant case, Crawford v. Geiger, is unpublished and only persuasive. That means an officer could still try to stop you or seize your device, even if the recording itself is legal under Ohio’s wiretap statute. The safest practice is to record openly, from a public vantage point, without interfering with the officer’s work.

Ohio does not have a state law that specifically regulates the collection or use of voiceprints or other biometric data. Unlike Illinois’ Biometric Information Privacy Act or Washington’s biometric law, Ohio has no statute that requires written consent, limits retention, or gives people a private right to sue over biometric data. Ohio’s only biometric-related law is the Ohio Data Protection Act, which is a voluntary cybersecurity safe harbor for businesses, not a consent or collection statute. There is no Ohio law that imposes special rules for recording or storing a voiceprint from a conversation.

Ohio lawyers may record conversations without consent as long as the recording is legal under Ohio’s wiretap statute. The Ohio Board of Professional Conduct adopted this position in Advisory Opinion 2012-1, which withdrew an earlier opinion that had treated surreptitious recording as presumptively unethical. The 2012 opinion states: “A surreptitious, or secret, recording of a conversation by an Ohio lawyer is not a per se violation of Prof.Cond.R. 8.4(c) if the recording does not violate the law of the jurisdiction in which the recording takes place.” The opinion adds that lawyers should not record clients or prospective clients without consent, due to duties of loyalty and confidentiality, but recording adverse parties, witnesses, or opposing counsel is generally permitted if the recording is legal.

Ohio’s one-party-consent rule applies the same way regardless of location—home, workplace, public street, etc.—because the statute regulates interception of communications, not the location of the recorder. Ohio Revised Code § 2933.52(B)(4). However, if the conversation includes someone who isn’t part of the exchange and is speaking privately, that person’s statements may carry a reasonable expectation of privacy under Ohio Revised Code § 2933.51(B). Because no Ohio appellate decision has squarely addressed this scenario under the current statutory text, the safest approach is to avoid recording such private exchanges without consent or to ask first.

Imagine you’re in a heated argument with a contractor in your office. You pull out your phone and record the conversation because you want to keep a record of what was said. Under Ohio’s one-party-consent rule, this is legal because you’re part of the conversation. The recording would be admissible in court if relevant, subject to ordinary evidentiary rules. However, if the contractor lowers their voice and steps into a corner to speak privately, the conversation might carry a reasonable expectation of privacy. In that case, the recording could run into legal gray areas because Ohio courts haven’t clearly decided whether such behavior changes the analysis. The safest move is to ask first or avoid recording if the other person is clearly trying to keep the conversation private.

Ohio’s wiretap statute targets communications that include an aural transfer, such as human speech. Ohio Revised Code § 2933.51(B) defines an “oral communication” to require an “aural transfer” uttered with an expectation of non-interception; a video-only capture with no audio does not meet the “aural transfer” or “communication” elements and therefore falls outside the core wiretap prohibition. Separately, Ohio’s voyeurism statute, ORC 2907.08, restricts video recording (audio or silent) of a person’s “state of nudity” or similar intimate exposure in a place where they have a reasonable expectation of privacy; this is not relevant to recording public disputes or police encounters, but could apply if a wearable inadvertently captures someone in a private or undressed state.
