The surveillance program PRISM by the US secret service NSA has reminded us that all of our activities online may be monitored without giving us the chance to understand whether we really are targeted or what the purpose of this monitoring is. Information is being collected about us all but we have little understanding about how it is being used.
We do though have some means of learning what information we are giving away and this can allow us to make conscious decisions about how we want to continue to use the internet. Some traces are difficult to avoid, but there are also many things we can do to reduce our digital shadows.
