Systems and methods for improving security

A method, comprising:

• identifying a query associated with a user account;
• accessing, by a database driver, an ID graph database to obtain an ID graph relating to the user account;
• and
• determining whether the user account is a target account type based at least on the ID graph, wherein
• the ID graph includes a plurality of nodes and a plurality of edges, each of the plurality of edges connecting two nodes,
• each of the plurality of nodes includes at least one of a register ID, a login ID, a payment ID, a background check ID, or a face ID, and
• each edge that connects two nodes includes at least one of a user type associated with the two nodes, a timestamp when the edge is connected, or source information of the edge.

A non-transitory computer readable medium, comprising at least one set of instructions, when accessed by at least one processor of a system for improving security, causes the system to execute a method, the method comprising:

• identifying a query associated with a user account;
• accessing, by a database driver, an ID graph database to obtain an ID graph relating to the user account;
• and
• determining whether the user account is a target account type based at least on the ID graph, wherein
• the ID graph includes a plurality of nodes and a plurality of edges, each of the plurality of edges connecting two nodes,
• each of the plurality of nodes includes at least one of a register ID, a login ID, a payment ID, a background check ID, or a face ID, and
• each edge that connects two nodes includes at least one of a user type associated with the two nodes, a timestamp when the edge is connected, or source information of the edge.
