1. A data processing system executing on at least one processor configured to facilitate identification of a first device seeking to communicate with one or more third party online service providers, the data processing system comprising:a session handler configured to communicate with the first device to determine at least one unique identifier assigned to the device, the session handler configured to request additional context verification from one or more of: the first device, an operator of the first device, or one or more other devices, wherein each unique identifier has a respective value indicative of a representative level of trust associated with that unique identifier, the respective value being configured for use as part of the trust score computation by the trust scoring engine;
a trust scoring engine, in communication with the session handler, configured to compute a trust score based on (i) the trustworthiness of the first device unique identifier, and (ii) results from the additional context verification;
a communication interface in which the third party service provider receives the first device unique identifier and the computed trust score of the first device;
wherein the trust scoring engine is further configured to:
determine which, if any, of multiple thresholds of identification risk the trust score exceeds, wherein each threshold represents a level of identification risk; and
if the trust score exceeds at least one of the thresholds of the identification risk, determine a level of access to provide the first device access to an online service of the one or more third party online service providers that corresponds to the least restrictive identification risk threshold level exceeded by the trust factor.
