In this second part I'm going to discuss the working procedure of the UPI - Unified Payments Interface dealing with its mechanisms of newtorking & operating system of UPI Protocals, Security Analysis & User Registration Process through BHIM UPI App so let's begin

UPI - Protocols: 

The mechanism of UPI Protocols has been introduced for security purposes and to access authentic process of the UPI Payments. 

The main goal of the UPI protocols is to fascinate financial gerprinting and to verify the credentials in puts by user that helps to open a bank account & to do transactions. 

While on the other hand, By default authentication workflow UPI protocols secure the user account from hackers. 

In order to capture the protocols data a method is required to analysis the data that is - App Reversing Engineering technique helps to send and received protocols data which are being processed by UPI system through cellphone by putting a physical SIM and helps to run the UPI apps for Anti- Emulation. 

 BHIM - UPI - Protocols: BHIM - UPI App - 

BHIM is an abbreviation of Bharat Interface For Money refers to an government reference implement payment app in which UPI version 1.0 protocol has been installed to execute the system.

In addition to execute the protocols emphasis laid on the basis of two process - Alternative workflow - I deals with user registered cell number, UPI requires Alice server for user registration, UPI pass a keyed code to cell number to generate HTTPS massage and send Alice server with pass code and thereby to complete device registration. 

UPI Server send 4 digit confirmation code to Alice server to complete the full process of hard binding.

Nevertheless in the second process of the UPI Protocols - II is processed when Alice server of an existing user is being changed due to some purpose then UPI server has rebind the existing cell number with a new cell phone where UPI server automatically finds the user I'd for Alice while the process is being done by BHIM UPI App.

Both the workflow required secret pass codes to open bank account therefore it helps to setup another bank account with the help of Alice generate pass codes  in this procedure the operating network of UPI Protocols makes convenient for Alice server and device because it helps to user to transfer bank account to another with new cell phone provies a hussle-free user interface.
