Abstract: A computer implemented method includes receiving anonymous entity information from a client device via a network. The anonymous entity information is used to register a user associated with the client device. User supplied anonymous information about the user is received from the network. Sensor signals from the client device are collected from the network. The user supplied anonymous information is combined with the sensor signals to produce an anonymized data package for the user. The anonymized data package is made accessible to vendor machines via the network. Transaction offers from the vendor machines are collected from the network. The transaction offers are supplied to the user device via the network. A selected transaction offer is received from the user device via the network. Network communication between the user device and a vendor machine associated with the selected transaction offer is coordinated.
