1. A system, comprising: circuitry configured for acquiring obscured data, the obscured data indicative of a user device and a purchase initiated by the user device, the obscured data configured to avoid uniquely identifying the user device; circuitry configured for selecting one or more services configured to be carried out on the user device, the one or more services selected at least partly based on the acquired obscured data and capable of access to at least a portion of personal data associated with the user device; circuitry configured for offering an alternative for payment for the purchase initiated by the user device, including at least offering an option in which a monetary payment for the purchase initiated by the user device is decreased in exchange for authorization for access to identifying data configured to uniquely identify the user device and for access to the at least a portion of personal data associated with the user device; circuitry configured for receiving, responsive to an indication of acceptance of the alternative for payment for the purchase initiated by the user device, one or more transformations configured to transform at least a portion of the obscured data into identifying data relating to the user device accepting the alternative for payment for the purchase initiated by the user device for use by the one or more services; and circuitry configured for using the identifying data to access the at least a portion of personal data associated with the user device via the one or more services.
