Tokenized device identifier generator and tracking system

A computer-implemented method for identifying a client computing device and determining whether to provide access to computing resources of a computing network, the method implemented by an access mapping computing device including at least one processor in communication with at least one memory device, the method comprising:

• building an identification database storing a plurality of data records, each data record including (i) a verified device identifier identifying a corresponding client computing device, the verified device identifier including tokenized device data of the corresponding client computing device, and (ii) an access profile associated with the verified device identifier and associated with at least one previous access instance in which the corresponding client computing device accessed or attempted to access the computing resources of the computing network;
• receiving, during a current access instance, device data associated with a candidate client computing device accessing or attempting access to the computing resources of the computing network;
• tokenizing the device data to generate a candidate device identifier for the candidate client computing device;
• querying the identification database with the candidate device identifier;
• and
• in response to a successful query of the identification database, returning the verified device identifier retrieved from the identification database that corresponds to the candidate device identifier.

At least one non-transitory computer-readable storage medium having computer-executable instructions stored thereon, wherein, when executed by at least one processor of an access mapping computing device, the computer-executable instructions cause the at least one processor to:

• build an identification database storing a plurality of data records, each data record including (i) a verified device identifier identifying a corresponding client computing device, the verified device identifier including tokenized device data of the corresponding client computing device, and (ii) an access profile associated with the verified device identifier and associated with at least one previous access instance in which the corresponding client computing device accessed or attempted to access the computing resources of the computing network;
• receive, during a current access instance, device data associated with a candidate client computing device accessing or attempting access to the computing resources of the computing network;
• tokenize the device data to generate a candidate device identifier for the candidate client computing device;
• query the identification database with the candidate device identifier;
• and
• in response to a successful query of the identification database, return the verified device identifier retrieved from the identification database that corresponds to the candidate device identifier.
