News just breaking of what is believed to be the second largest data breach in Australian history. It reminds us that much of our personal information is held on computers these days and the ever present concern that someone might gain access to it in an unauthorised way. 

While Governments and businesses cannot reasonably be expected to offer 100% certainty about the safety of the information we give them (even crossing the road has risks), we shouldn't forget the clear advantages of storing and sharing data. Sharing health records between health professionals in different organisations treating the same patient can clearly save lives and lead to better, quicker, safer care.  So the benefits can easily outweigh the inevitable threats.
