Methods and systems for managing data

A computationally-implemented system, comprising

• circuitry for receiving data regarding one or more properties of a device, said data not particularly identifying the device;
• circuitry for identifying one or more services configured to be provided to a user of the device, said one or more services requiring access to particular data controlled by the device, wherein access to the particular data controlled by the device is managed by the device;
• and
• circuitry for requesting access to the particular data controlled by the device, in exchange for providing one or more of the identified one or more services.

A device defined by a computational language comprising:

• one or more interchained physical machines ordered for receiving data regarding one or more properties of a device, said data not particularly identifying the device;
• one or more interchained physical machines ordered for identifying one or more services configured to be provided to a user of the device, said one or more services requiring access to particular data controlled by the device, wherein access to the particular data controlled by the device is managed by the device;
• and
• one or more interchained physical machines ordered for requesting access to the particular data controlled by the device, in exchange for providing one or more of the identified one or more services.
