Judging by the rash of recent stories , either Canadian police are becoming adept at spotting computer crimes or there has been a mushrooming in the number of such crimes (in that country) over the last year. Following on from the news item in last month's bulletin ('Hacker uses data switch exchange') another case has arisen which revolves round communications and computer security.

Three officers of the Toronto-based company Dial Data Services are now appealing against charges of violating Canadian criminal law for allegedly altering information held on computer files at the Milwaukee, Wisconsin data processing department of A 0 Smith Data Systems. The alleged offences are said (by the prosecution) to have taken place in 1982 and to have involved amendments to payroll data and other financial records held at Smith's, by means of remote terminals connected up by telephone lines. As the alteration of this data did not actually 'damage' the computer tape, and as none of the data was actually destroyed, the three accused argue that the sections of the Criminal Code under which they are charged does not apply. This argument was dismissed by the Ontario Supreme Court last June but is now being considered by the Ontario Court of Appeal. Legal specialists await the outcome with considerable interest as a test of the current limits of jurisdiction of Canadian federal law.
