a processor; and
a non-transitory computer-readable medium having stored thereon instructions that are executable by the processor to cause the system to perform operations comprising:
receiving, from a first user device, a request to conduct an electronic transaction;
extracting, from the first user device, a first Internet Protocol Version 6 (IPv6) network address and one or more first characteristics associated the first user device, wherein the one or more first characteristics comprise one or more hardware components and one or more software components, and wherein the first IPv6 network address includes a first key that uniquely identifies the first user device;
accessing an electronic database that stores information associated with a second user device that was used to conduct one or more previous electronic transactions, the stored information including a second IPv6 network address and one or more second characteristics associated with the second user device, wherein the second IPv6 network address includes a second key that uniquely identifies the second user device;
calculating, based on a comparison of the first IPv6 network address against the second IPv6 network address, or on a comparison of the one or more first characteristics against the one or more second characteristics, a risk score of conducting the electronic transaction, wherein the risk score is calculated at least in part by comparing the first key against the second key; and
determining whether to approve the electronic transaction based on the calculated risk score.
