US 2021/0243153 A1 · DEVICE IDENTIFICATION SYSTEMS

Abstract

Methods and systems for a device identification system may be provided. The device identification system may determine an identity of a user device associated with a transaction. The identity may be determined by network address information, hard link information, soft link information, and/or other such information. The network address information may include IPv4 information, IPv6 information, a device ID, and/or other such information. The identity of the user device may be determined and a transaction conducted from the user device may be assigned a fraudulent transaction risk score according to the information. Transactions that are determined to be at a high risk of fraud may be reviewed or otherwise flagged and/or canceled.

A system, comprising:

a processor;
a network interface device;
and
a non-transitory computer-readable medium having stored thereon instructions executable to cause the system to perform operations comprising:
based on information indicating that a particular user account initiated a first electronic transaction using a first user device, storing first device data of the first user device in association with the particular user account, wherein the first device data includes:
a first IPv6 network address corresponding to the first user device;
a first characteristic information set including one or more values corresponding to one or more hardware characteristics of the first user device;
and
a second characteristic information set including one or more values corresponding to one or more software characteristics of the first user device;
responsive to an indication that the particular user account has initiated a second electronic transaction using a second user device, accessing second device data of the second user device and user account data of the particular user account, wherein the second device data includes:
a second IPv6 network address corresponding to the second user device;
a third characteristic information set including one or more values corresponding to one or more hardware characteristics of the second user device;
and
a fourth characteristic information set including one or more values corresponding to one or more software characteristics of the second user device;
determining a similarity of the second user device to the first user device based on a comparison of the first device data to the second device data, including:
a comparison of the first IPv6 network address to the second IPv6 network address;
a comparison of at least a portion of the first characteristic information set to at least a portion of the third characteristic information set;
and
a comparison of at least a portion of the second characteristic information set to at least a portion of the fourth characteristic information set;
based on the similarity of the second user device to the first user device, and based on at least a portion of the user account data of the particular user account, calculating a transaction risk score for the second electronic transaction;
and
processing the second electronic transaction based on the calculated transaction risk score.

A method, comprising:

based on information indicating that a particular user account initiated a first electronic transaction using a first user device, a service provider computer system storing first device data of the first user device, wherein the first device data includes:
a first IPv6 network address corresponding to the first user device;
a first characteristic information set including one or more values corresponding to one or more hardware characteristics of the first user device;
and
a second characteristic information set including one or more values corresponding to one or more software characteristics of the first user device;
responsive to information indicating that the particular user account has initiated a second electronic transaction using a second user device, the service provider computer system accessing second device data of the second user device and user account data of the particular user account, wherein the second device data includes:
a second IPv6 network address corresponding to the second user device;
a third characteristic information set including one or more values corresponding to one or more hardware characteristics of the second user device;
and
a fourth characteristic information set including one or more values corresponding to one or more software characteristics of the second user device;
determining a similarity of the second user device to the first user device, by the service provider computer system, based on a comparison of the first device data to the second device data, including:
a comparison of the first IPv6 network address to the second IPv6 network address;
a comparison of at least a portion of the first characteristic information set to at least a portion of the third characteristic information set;
and
a comparison of at least a portion of the second characteristic information set to at least a portion of the fourth characteristic information set;
based on the similarity of the second user device to the first user device, and based on at least a portion of the user account data of the particular user account, the service provider computer system calculating a transaction risk score for the second electronic transaction;
and
causing the second electronic transaction to be processed based on the calculated transaction risk score.

15 more elements

A non-transitory computer-readable medium having stored thereon instructions executable by a first server to cause the first server to perform operations comprising:

accessing information indicating that a particular user account initiated a first electronic transaction using a first user device, including accessing first device data that includes:
a first IPv6 network address corresponding to the first user device;
a first characteristic information set including one or more values corresponding to one or more hardware characteristics of the first user device;
and
a second characteristic information set including one or more values corresponding to one or more software characteristics of the first user device;
responsive to an indication that the particular user account has initiated a second electronic transaction using a second user device, accessing second device data of the second user device and user account data of the particular user account, wherein the second device data includes:
a second IPv6 network address corresponding to the second user device;
a third characteristic information set including one or more values corresponding to one or more hardware characteristics of the second user device;
and
a fourth characteristic information set including one or more values corresponding to one or more software characteristics of the second user device;
determining a similarity of the second user device to the first user device based on a comparison of the first device data to the second device data, including:
a comparison of the first IPv6 network address to the second IPv6 network address;
a comparison of at least a portion of the first characteristic information set to at least a portion of the third characteristic information set;
and
a comparison of at least a portion of the second characteristic information set to at least a portion of the fourth characteristic information set;
based on the similarity of the second user device to the first user device, and based on at least a portion of the user account data of the particular user account, calculating a transaction risk score for the second electronic transaction;
and
processing the second electronic transaction based on the calculated transaction risk score.
