Guidelines for controls that protect privacy of information within the computer and govern its divulgence to authorized users. Five technical safeguards are needed: (1) protection of central and demountable computer storage media; (2) encryption or physical protection of the circuits; (3) computer hardware safeguards of the timesharing system; (4) software safeguards to monitor user access to files; and (5) administrative and management controls that are security conscious. Government regulation may be required to protect the privacy of personal files, since there is no databank "industry" or trade organization for self-policing, and since the operator, who is necessarily profit-oriented, may not know nor care to what use his client wants to put the data. Consequently, safeguards should be formulated before data banks proliferate widely and without control. 12 pp.
