Copyright is an essential tool in the spread of new ideas, and the workplace has become ground zero for infringement. Ask employees up and down the corporate hierarchy, and they’ll tell you that whisking information electronically to co-workers is integral to their jobs. Their employers will emphatically agree. But unauthorized swaps of information also carry enormous potential risk: Ordinary office exchanges, so natural to the digital world, can easily violate the copyright rights of others and bring costly lawsuits or settlements. Now the same technology that has dramatically defined the Internet age is drawing a new roadmap to compliance, with software tools that simplify adherence to copyright requirements.
