US Patent 10268840 Systems and methods of determining compromised identity information

In some embodiments, a compromised data exchange system may include an interface configured to couple to a network, a processor, and a memory accessible to the processor. The memory may be configured to store instructions that, when executed, cause the processor to extract data from one or more websites using a crawler, detect portions within the data that resemble personally identifying information (PII) data based on PII data patterns using a risk assessment module, and to compare a detected portion to data within a database of disassociated compromised PII data to determine a match using the risk assessment module. The instructions may further cause the processor to selectively assign a risk score to a data item within the database in response to determining the match using a risk scoring module.
