1. A method for verifying an identity claim associated with an online access request, the access request for performing a transaction on a server, using an identity verification system comprising a computer processor and a non-transitory computer-readable storage medium accessible through the computer processor, wherein the non-transitory computer-readable storage medium comprises a plurality of instructions which, when executed by the computer processor, perform the method comprising: receiving access request data related to the identity claim using an identity evaluation subsystem, wherein the access request data comprises a digital credential related to the identity claim; performing operations, using an identity information correlation subsystem, comprising: retrieving at least one personal identification information (PII) item related to the digital credential and characterized by a first focus; deriving at least one verified personal attribute from the at least one PII item, wherein the at least one verified personal attribute is characterized by a second focus and wherein the second focus of the at least one verified personal attribute does not match the first focus of the at least one PII item; correlating the at least one verified personal attribute with the digital credential to define a correlated attribute; and storing the correlated attribute to a verified identity record; creating, using the identity evaluation subsystem, an identity match indicator; transmitting, using the identity evaluation subsystem, the identity match indicator to the server; and verifying the identity claim, by the server, using the identity match indicator to allow or reject the access request.
