Use of personal computers in the industry and commerce has expanded dramatically in the last decades. Large gains in employment productivity are possible as a result of this technology. However ensuring the security of the processes and the privacy of data is a very hard problem. Solutions that ensure security by preventing access by legitimate users are inconsistent with the gains in productivity that are possible. The general problem of computer security is being faced by government and by academic and industrial research with some notable success.
