The widespread use of resource-sharing systems has introduced new complexities to the problem of safeguarding computer information. This paper reviews aspects of security and privacy in both widely shared data networks and private databases. Three examples are discussed: (1) the FBI's National Crime Information Network, using state-shared information, (2) census data, and (3) tax information. The issues of access-control are raising legal questions which must be dealt with through legislation. The paper recommends further research and analysis in the area of computer-oriented crime legislation.

The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
