Identifiability and Traceability Online

Last month I described the ability to track users sessions with browser data. A recent posting on IT Law in Ireland highlighted a series of blog posts elsewhere that give further insight into what is possible.

Well, I just got round to reading them properly. The posts on Freedom to Tinker by David Robinson and Harlan Yu are:

• Identifying John Doe: It might be easier than you think
• What Third Parties Know About John Doe
• The Traceability of an Anonymous Online Comment

The conclusion? It is possible to trace and identify individuals easier than you may think. We are dropping evidence like dead skin cells as we traverse the internet. Fact or fiction? Well the US Defense Advanced Research Projects Agency (DARPA) are taking it seriously with a recent call for research into cyber genetics, cyber anthropology and cyber physiology in its Cyber Genome Program. DARPA hopes to develop advanced methods to fingerprint or identify the origins of a cyber attacks by examining digital artifacts, and presumably other criminal activities utilising computer technology.

Getting a bit more down to earth, web site owners need to consider what information is being gathered and why, ensure this is legal, check that consent is implied or has been explicitly given for the purposes and what monitoring and analysis is performed on the data. It could be easy for system developers to carried away with tracking and tagging. Contracts with third parties should state clearly what the expectations are about the security and privacy of information, to protect web site users (employees, customers, clients, citizens) and the business.
