 Every action we take leaves a trail of information that could, in principle, be recorded and stored for future use. For instance, one might use the older forms of information technologies of pen and paper and keep a detailed diary listing all the things one did and thought during the day. It might be a daunting task to record all this information this way but there are a growing list of technologies and software applications that can help us collect all manner of data, which in principle, and in practice, can be aggregated together for use in building a data profile about you, a digital diary with millions of entries. Some examples of which might be: a detailed listing of all of your economic transactions; a GPS generated plot of where you traveled; a list of all the web addresses you visited and the details of each search you initiated online; a listing of all your vital signs such as blood pressure and heart rate; all of your dietary intakes for the day; and any other kind of data that can be measured. As you go through this thought experiment you begin to see the complex trail of data that you generate each and every day and how that same data might be efficiently collected and stored though the use of information technologies. It is here we can begin to see how information technology can impact moral values. As this data gathering becomes more automated and ever-present, we must ask who is in control of collecting this data and what is done with it once it has been collected and stored? Which bits of information should be made public, which held private, and which should be allowed to become the property of third parties like corporations? Questions of the production, access, and control of information will be at the heart of moral challenges surrounding the use of information technology.
