Abstract: A system and a method of data communication between a first computing device, associated with a first user, and at least one second computing device associated with a second user may include: receiving, by the first computing device, one or more data elements pertaining to details of a transaction request from the second computing device, via a voice channel; extracting said transaction request details by the first computing device; transmitting, by the first computing device, one or more authentication data elements of an electronic wallet module, comprised in the first computing device, to the second computing device, via the voice channel; and carrying out the requested transaction by the first computing device, based on the extracted transaction request details and the electronic wallet authentication data.

Abstract: Systems and methods of providing context-based fraud detection receive a transaction request from a user, the transaction request comprising request parameters; implement a fraud analysis on the transaction request based on the transaction request and/or the request parameters; determine an initial likelihood of fraud based on the fraud analysis; if the initial likelihood of fraud meets a likelihood threshold: identify a suspected fraud type based on at least one of the transaction request, the request parameters, or the fraud analysis; select questions associated with the suspected fraud type to be presented to the user; receive a voice input from the user in response to the presented questions; implement a second fraud analysis on the voice input based on at least one of the transaction request, the request parameters, or the fraud analysis; and determine a revised likelihood of fraud based on the second fraud analysis.
