A statement before a State Assembly committee on the problem of protecting computer information. The main policy issue is that of the invasion of privacy. The computer-based files of information compiled for ease in checking credit do benefit the citizen, but nonetheless threaten him because of the current lack of legal or industry controls on information dissemination. Technically, the problem is one of lagging system-design expertise, which would be alleviated through the stimulation provided by legal constraints. Self-policing among file operators is unlikely, and legal penalties may have to be imposed in the civilian sector similar to those for defense classified systems. The high reliability in protecting computer-based file information in the defense systems is due to a concerted effort to coordinate hardware, software, management, and physical protective schemes. Only this combination could secure computer systems in the civilian sector, as well. 7 pp.
