Method and system for authorization of transactions

Abstract:

A method for transaction authorization includes generation of a master authentication code based on an authorization request for a transaction by a server. The transaction is initiated by a user by way of a transaction application installed on a user-computing device. The server splits the master authentication code into a first authentication code and a second authentication code. The first authentication code is communicated to the transaction application and the second authentication code is communicated to the user by the server. The transaction application generates a response code based on the first authentication code and the second authentication code. The server receives the response code from the transaction application and processes the transaction based on a match between the response code and the master authentication code.
