I submit data you can use and you submit the data you extracted and used from me? The ideal would be when I submit a search query to your server and it would respond "I have collected (this) data from you" "I have put for auction data.{xyz} on market Y" "The companies bidding were a,b,c and they offered amount g,h,i" "Company U won the bid, that's why you're seeing this ad". If you think about it, there's no way someone would be transparent enough to give this data to the users. If "you" aren't willing to share your "sensor" data, why should we be forced to share ours?
