Abstract

Certain embodiments of the disclosed technology include systems and methods for increasing efficiency in the detection of identity-based fraud indicators associated with a loan application. A method is provided that includes receiving applicant data associated with a loan application having a plurality of applicants. The application data includes at least a name, a social security number, and a street address for each of the plurality of applicants. The method includes querying one or more databases with the applicant data; receiving a plurality of independent information in response to the querying; determining a validity indication of the applicant data; creating disambiguated applicant records; determining relationships among the disambiguated applicant records; scoring at least one parameter of the applicant data; determining one or more indicators of fraud based on the scoring; and outputting, for display, one or more indicators of fraud.

Claims

1. A computer-implemented method comprising:

receiving, from a first information source, applicant data associated with a loan application having a plurality of applicants, wherein the applicant data comprises at least a name, a social security number, and a street address for each of the plurality of applicants;

querying one or more of a public database and a private database with at least a portion of the applicant data;

receiving, from a second information source that is independent of the first information source, a plurality of independent information in response to the querying;

determining, with one or more computer processors in communication with a memory, based at least in part on a comparison of the applicant data with at least a portion of the plurality of independent information, a first validity indication of the applicant data;

creating, with the one or more computer processors, disambiguated applicant records responsive to the first validity indication by one or more of;

performing data cleansing on one or more of the applicant data and the plurality of independent information to eliminate one or more name variations; and

adding metadata record to one or more of the applicant data and the plurality of independent information;

determining, with the one or more computer processors, relationships among the disambiguated applicant records by one or more of;

creating a core join data structure with at least a portion of all available disambiguated applicant records;

splitting the core join data structure into persisted parts; and

clustering one or more of the persisted parts and the disambiguated applicant records;

scoring, with the one or more computer processors and based at least in part on the determined relationships among the disambiguated applicant records, at least one parameter of the applicant data;

determining, with the one or more computer processors, one or more indicators of fraud based on the scoring of the at least one parameter; and

outputting, for display, one or more indicators of fraud.

2.

an indication of whether or not one or more of the plurality of applicants is deceased;

a date of death when the one or more of the plurality of applicants is indicated as deceased;

independent address information associated with the one or more of the plurality of applicants;

address validity information associated with the applicant data;

one or more records associated with the applicant data; and

no information.

10. The method of claim 1, wherein receiving the plurality of independent information comprises receiving one or more records comprising one or more of housing records, vehicular records, marriage records, divorce records, hospital records, death records, court records, property records, incarceration records, tax records, and utility records, wherein the utility records comprise one or more of utility hookups, disconnects, and associated service addresses.

11. The method of claim 1, wherein receiving the independent information comprises receiving one or more physical addresses of relatives or associates of one or more of the plurality of applicants.

12. The method of claim 1, wherein the one or more public or private databases are independent of a government agency.

13. A system comprising:

at least one memory for storing data and computer-executable instructions; and

at least one processor configured to access the at least one memory and further configured to execute the computer-executable instructions to;

receive, from a first information source, applicant data associated with a loan application having a plurality of applicants, wherein the applicant data comprises at least a name, a social security number, and a street address for each of the plurality of applicants;

query one or more of a public database and a private database with at least a portion of the applicant data;

receive, from a second information source that is independent of the first information source, a plurality of independent information in response to the querying;

determine, with the at least one processor, based at least in part on a comparison of the applicant data with at least a portion of the plurality of independent information, a first validity indication of the applicant data;

create, with the at least one processor, disambiguated applicant records responsive to the first validity indication by one or more of;

performing data cleansing on one or more of the applicant data and the plurality of independent information to eliminate one or more name variations; and

adding metadata record to one or more of the applicant data and the plurality of independent information;

determine, with the at least one processor, relationships among the disambiguated applicant records by one or more of;

creating a core join data structure with at least a portion of all available disambiguated applicant records;

splitting the core join data structure into persisted parts; and
