Simon Crawford published this paper with the 1997 Faculty of Law, University of Ottawa on Efficiency in information transfer has increased rapidly in the last decade, and with this efficiency new threats to the security of that information have surfaced. The unauthorized disclosure of information by banks was, at one time, a personal matter. Typically a customer might have one complaint with one bank about an isolated injurious breach of confidence. However, as banks amass greater storehouses of client information, and as the commercial potential of that information is increased, the threat of grand scale disclosures becomes a reality.
