A computing system and method for managing an identity of a user are provided. A server may be configured to communicate with each of a plurality of client devices in corresponding request and response streams. An inference engine is configured to monitor the request and response streams for identifying factors that distinguish each of the plurality of client devices from other of the plurality of client devices. Upon detecting one or more of the identifying factors for each of the two or more client devices that match within a threshold probability, the inference engine makes an inference that two or more of the plurality of client devices are used by the user. Based upon the inference, the inference engine creates a virtual identity record at the server linking the two or more client devices.
