In this paper, we show that in some narrow instances the ownership of personal data is actually and legally possible: new "user-held data" technologies are emerging and help individuals have their personal data in their "personal data clouds"; Individuals can collect their data from various sources (such as online accounts, wearable devices, IoT, and manually input data). We show that such ownership of user-held data is not different from other types of assets such as money in your bank account, intermediate securities, receivables, floating charge, and your crypto.
