System and method of performing secured transactions in a communication network

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, the method comprising:

• receiving, by at least one processor of the first computing device associated with an encoder/decoder (CODEC) module and a natural language processing (NLP) module, an indication of a forthcoming transaction request from the second computing device, via a digital voice channel during a voice call between the first user and the second user;
• transferring an electronic wallet module of the first computing device into a tapping state based on the received indication to enable tapping onto the digital voice channel, and extract transaction request details;
• receiving, by the at least one processor of the first computing device, via the digital voice channel during the voice call, a first audio signal comprising first audible voice data elements and first non-audible digital data elements that piggybacks on the first audible voice data elements in a steganographic manner, wherein the first audible voice data elements comprise first transaction request details, and wherein the first non-audible digital data elements comprise second transaction request details;
• extracting, by the at least one processor employing the NLP module, the first transaction request details from the first audible voice data elements;
• extracting, by the at least one processor employing the CODEC module, said second transaction request details from the first non-audible digital data elements;
• forwarding, by the at least one processor, the extracted first transaction request details and the extracted second transaction request details to the electronic wallet module;
• and
• transmitting, by the at least one processor to the second computing device via the digital voice channel during the voice call, a second audio signal comprising second audible voice data elements and second non-audible digital data elements that piggybacks on the second audible voice data elements in a steganographic manner, wherein the second non-audible digital data elements comprise one or more authentication data elements of the electronic wallet module.
