(a)The Attorney General shall establish and maintain an online database to be known as the Prohibited Armed Persons File. The purpose of the file is to cross-reference persons who have ownership or possession of a firearm on or after January 1, 1996, as indicated by a record in the Consolidated Firearms Information System, and who, subsequent to the date of that ownership or possession of a firearm, fall within a class of persons who are prohibited from owning or possessing a firearm.

(b)Except as provided in subdivision (c), the information contained in the Prohibited Armed Persons File shall only be available to those entities specified in, and pursuant to, subdivision (b) or (c) of Section 11105, through the California Law Enforcement Telecommunications System, for the purpose of determining if persons are armed and prohibited from possessing firearms.

(c)The information contained in the Prohibited Armed Persons File shall be available to researchers affiliated with the California Firearm Violence Research Center at UC Davis following approval by the institution’s governing institutional review board, when required. At the department’s discretion, and subject to Section 14240, the data may be provided to any other nonprofit bona fide research institution accredited by the United States Department of Education or the Council for Higher Education Accreditation for the study of the prevention of violence, following approval by the institution’s governing institutional review board or human subjects committee, when required, for academic and policy research purposes. Material identifying individuals shall only be provided for research or statistical activities and shall not be transferred, revealed, or used for purposes other than research or statistical activities, and reports or publications derived therefrom shall not identify specific individuals. Reasonable costs to the department associated with the department’s processing of that data may be billed to the researcher. If a request for data or letter of support for research using the data is denied, the department shall provide a written statement of the specific reasons for the denial.
