Abstract

The present invention includes systems and method for generating Virtual IDs (VIDs) and corresponding Virtual ID Chains (VICs) to anonymize and represent transactions between users, data sources, Virtual ID Management Platforms (VMP), and Third-Party Service Providers (TSPs). VIDs of embodiments are virtualized identifiers that may be used to anonymously and uniquely identify transaction participants. VIDs may be generated in a distributed manner as a party receiving transaction-related information generates a VID corresponding to the sending party. VICs of embodiments are virtualized arrays of VIDs that represent the sequence of interactions between parties to a transaction. VICs are preferably stored in association with transaction logs descriptive of the transaction represented by each VIC to facilitate subsequent processing. A VIC may be iteratively resolved to obtain one or more non-virtualized identifier corresponding to transaction participants represented by the VIC.

Dependent claims

A system for virtualizing identities associated with parties to a transaction using a Virtual ID Chain (VIC), comprising:

a first Virtual ID Management Platform (VMP) of one or more VMPs communicatively coupled to one or more data networks along a communication path corresponding to a transaction between a user and a Third-Party Service Provider (TSP) node, wherein a first non-virtualized VMP identifier (VMPID) corresponds to the first VMP, wherein the first VMP is configured to provide traceable virtual identification that anonymizes an identity of one or more parties to transactions to facilitate the transactions, and wherein the first VMP comprises memory and at least one processor configured to:
receive, from a data source node communicatively coupled to the one or more data networks, a virtualization request to facilitate the transaction between the user and the TSP node, wherein the virtualization request includes a Virtual ID (VID) corresponding to the user, a non-virtualized source identifier corresponding to the data source node (SID), and a transaction log corresponding to the transaction between the user and the TSP node, wherein the data source node has information associated with the user and corresponding to the transaction, wherein the VID corresponding to the user is generated by the data source node based on a non-virtualized user identifier corresponding to the user (UID), wherein the VID corresponding to the user is configured to resolve to provide the UID, wherein the TSP node is communicatively coupled to the one or more data networks, and wherein a non-virtualized TSP identifier (TSPID) corresponds to the TSP node;
generate a VID corresponding to the data source node based on the SID, wherein the VID corresponding to the data source node is configured to resolve to provide the SID;
store the VID corresponding to the data source node in association with the SID in a first virtualization record associated with the first VMP,
generate a first Virtual ID Chain (VIC) based on the VID corresponding to the user and the VID corresponding to the data source node, wherein the first VIC is configured to resolve to provide the VID corresponding to the user and the SID corresponding to the data source node represented in the VIC and enable resolving UID from the VID corresponding to the user;
store the first VIC in association with the transaction log in a first transaction record associated with the first VMP,
transmit the first VIC, the first VMPID, and the transaction log to a second VMP of the one or more VMPs or to the TSP node,
receive the first VIC from the second VMP or the TSP node in association with a processing request made by the TSP node,
resolve the first VIC to provide the SID corresponding to the data source node represented in the first VIC, and
transmit the processing request to the data source node corresponding to the SID and enable completion of the transaction without the UID of the user having been provided to the TSP node.

A method for anonymizing identities associated with parties to a transaction, comprising:

receiving, at a first Virtual ID Management Platform (VMP) from a first node, a virtualization request to facilitate a first transaction between a first user and a first Third-party Service Provider (TSP) node, wherein the first VMP is configured to provide traceable virtual identification that anonymizes an identity of one or more parties to transactions to facilitate the transactions, wherein the virtualization request to facilitate the first transaction comprises a non-virtualized identifier corresponding to the first node, a Virtual ID (VID) corresponding to the first user, and a first transaction log corresponding to the first transaction, wherein the VID corresponding to the first user is generated by a first data source node associated with the first user, wherein the VID corresponding to the first user is configured to resolve to provide a non-virtualized identifier corresponding to the first user, and wherein the first node is communicatively coupled to the first VMP;
generating, by the first VMP, a VID corresponding to the first node based on the non-virtualized identifier corresponding to the first node, wherein the VID corresponding to the first node is configured to resolve to provide the non-virtualized identifier corresponding to the first node;
storing, by the first VMP, the VID corresponding to the first node in association with the non-virtualized identifier corresponding to the first node in a first virtualization record associated with the first VMP;
generating, by the first VMP, a first Virtual ID Chain (VIC) based on the VID corresponding to the first user and the VID corresponding to the first node, wherein the first VIC is configured to resolve to provide the first VID corresponding to the first user and the non-virtualized identifier corresponding to the first node and enable resolving the VID corresponding to the first user to the non-virtualized identifier corresponding to the first user;
storing, by the first VMP, the first VIC in association with the first transaction log in a first transaction record associated with the first VMP;
transmitting, by the first VMP, the first VIC, a non-virtualized VMP identifier (VMPID) corresponding to the first VMP, and the first transaction log to a second VMP or to the first TSP node;
receiving, by the first VMP, the first VIC from the second VMP or the first TSP node in association with a processing request made by the first TSP node;
resolving, by the first VMP, the first VIC to provide the non-virtualized identifier corresponding to the first node represented in the first VIC;
and
transmitting, by the first VMP, the processing request to the first node based on the non-virtualized identifier corresponding to the first node and enabling completion of the first transaction without the non-virtualized identifier corresponding to the first user having been provided to the first TSP node.
