Sensor data will explode: trust needed
There are reasons to believe that sensor data will explode around us. This raises many questions, especially trust questions. Do we trust the data on which we base our decisions? If yes, on what grounds? Google has more or less introduced a mechanism for trust in websites: their PageRank algorithm serves as a primary trust indicator for many people. We will need such an indicator for sensor data as well.
Another trust question is the other way round: if you provide your sensor data to others, it may very well be that you give it away if your data is "for the common good". But if someone wants to make commercial use of your (sensor) data, you want to charge for it. So, the trust that YOU have on the USER of your data also plays a role. This might even go as far as privacy related data: for non-commercial use you are willing to share your data, but for commercial use you are only willing to share it if you get a fair compensation for it "sell your privacy". Do we need mechanisms for this?
