Abstract

Device identification scoring systems and methods may be provided that can increase the reliability and security of communications between devices and service providers. Users may select and configure additional identification factors that are unique and convenient for them. These factors, along with additional environmental variables, feed into a trust score computation that weights the trustworthiness of the device context requesting communication with a service provider. Service providers rely on the trust score rather than enforce a specific identification routine themselves. A combination of identification factors selected by the user can be aggregated together to produce a trust score high enough to gain access to a given online service provider. A threshold of identification risk may be required to access a service or account provided by the online service provider.
