In the last twenty-five years, the federal government and all fifty states have enacted new criminal laws that prohibit unauthorized access to computers. These new laws attempt to draw a line between criminality and free conduct in cyberspace. No one knows what it means to access a computer, however, nor when access becomes unauthorized. The few courts that have construed these terms have offered divergent interpretations, and no scholars have yet addressed the problem. Recent decisions interpreting the federal statute in civil cases suggest that any breach of contract with a computer owner renders use of that computer an unauthorized access. If applied to criminal cases, this approach would broadly criminalize contract law on the Internet, potentially making millions of Americans criminals for the way they write e-mail and surf the Web.
