Data Breach Notification. Any person that maintains or possesses records or data containing personal information of residents of Missouri that the person does not own or license, or any person that conducts business in Missouri that maintains or possesses records or data containing personal information of a resident of Missouri that the person does not own or license, shall notify the owner or licensee of the information of any breach of security immediately following discovery of the breach, consistent with the legitimate needs of law enforcement as provided in this section.

Definition of Personal Information. For Missouri residents, an individual's first name or first initial and last name in combination with any one or more of the following data elements that relate to the individual if any of the data elements are not encrypted, redacted, or otherwise altered by any method or technology in such a manner that the name or data elements are unreadable or unusable: (a) social security number; (b) driver's license number or other unique identification number created or collected by a government body; (c) financial account number, credit card number, or debit card number in combination with any required security code, access code, or password that would permit access to an individual's financial account; (d) unique electronic identifier or routing code, in combination with any required security code, access code, or password that would permit access to an individual's financial account; (e) medical information; or (f) health insurance information.

Definition of Breach. Unauthorized access to and unauthorized acquisition of personal information maintained in computerized form by a person that compromises the security, confidentiality, or integrity of the personal information. Good faith acquisition of personal information by a person or that person's employee or agent for a legitimate purpose of that person is not a breach of security, provided that the personal information is not used in violation of applicable law or in a manner that harms or poses an actual threat to the security, confidentiality, or integrity of the personal information.

Content of Notice. The notice shall at minimum include a description of the following: (a) the incident in general terms; (b) the type of personal information that was obtained as a result of the breach of security; (c) a telephone number that the affected consumer may call for further information and assistance, if one exists; (d) contact information for consumer reporting agencies; (e) advice that directs the affected consumer to remain vigilant by reviewing account statements and monitoring free credit reports.

Timing. The notification requirement is triggered upon discovery or notification of a breach of the security of the system. Notification must be without unreasonable delay, consistent with the legitimate needs of law enforcement, or with any measures necessary to determine the scope of the breach, identify the individuals affected, and restore the reasonable integrity, security and confidentiality of the data system. In the event of a breach affecting over 1000 people, the attorney general’s office and consumer reporting agencies (CRA) must be notified without unreasonable delay and must be informed of the timing, distribution, and content of the notices sent to Missouri residents.

Penalty. The Missouri Attorney General may enforce this law by seeking actual damages for a wilful and knowing violation and/or a civil penalty not to exceed $150,000 per breach.

Exemptions. An exemption from this notification statute may apply to an entity that is otherwise covered by a federal law such as the GLBA or HIPAA. As noted above, encrypted information is exempt so long as the breach doesn’t contain information or access code to decrypt the information but the Missouri statute does not define encryption.
