CA2747642A1 - User positive approval & authentication services - Google Patents

Abstract

The invention provides Users of Retail Payment and Identification instruments with the ability to review transaction details and approve transaction by capturing UVM
in User controlled environment and Issuers of these instruments with the ability to positively authenticate Users in Issuer controlled environment. The invention accounts for real time legacy or non-legacy processing systems to provide an authorization request from POA to Issuer Host. The invention introduces two UPAAS components - User Gateway and User Application. The UPAAS User Gateway is implemented in an Issuer controlled environment enabling interface between Issuer legacy Host and UPAAS User Applications. The UPAAS
User Application can be implemented on any device supporting communication protocol such as TCP/IP without any hardware changes enabling the User to login to UPAAS
User Gateway, review and approve or decline a specific transaction in real time by entering UVM, such as PIN, for User authentication purposes.

Description

User Positive Approval & Authentication Services Inventors: Branislav R Sikljovan, Guelph, ON, Canada, Radosav Andric, Toronto, ON, Canada BACKGROUND OF THE INVENTION

The foundation of the invention was a realization of the existing problems and opportunities that emerging technologies are bringing along in the areas of transaction approval and User authentication for Retail Payment and Identification transactions.

Recognized Problems = For a number of years the Card industry has been facing demands for a stronger Cardholder authentication and better protection of User and Payment instrument proprietary information. The Card industry responded with EMV- chip cards where an offline PIN was introduced replacing or substituting signature as CVM. An Offline PIN is significantly more reliable than a signature however it came with a price: the cost of EMV
implementation and maintenance is significant and is billed to all parties: Merchants/POA, Acquirer, Network and Issuers. Another downside is that the PIN remained captured at POA and User verification remained within the POA environment. To mitigate the risks the Payment Card Industry (PCI) introduced PED and Data Security standards which improved security however also further increased the cost of implementation and maintenance. Verification of a CVM at the POA
means that the Issuer is advised of the Cardholder Verification Result, but not actually performing User authentication, which opens up doors for "wedge" (man-in-the middle) attacks and other fraud risks.

= The personal and traveler's cheques industry currently provides the ability to validate the cheques or drafts being presented, verify the history of the User (account holder), to validate the Routing Number and verify the User Account number status, However User authentication is not currently available for cheque transactions which along with the cost of Cheque Verification processing contributed to the constant decline of cheque use.

= Users of identification instruments like Insurance and Health cards are either not authenticated at all or the authentication is performed by the acceptor using other pictured IDs, like a Driver's license.

User Positive Approval & Authentication Services Inventors: Branislav R Sikljovan, Guelph, ON, Canada, Radosav Andric, Toronto, ON, Canada Perceived Opportunities = Mass adoption of data enabled devices enables a reach to Users of Retail payment and Identification instruments in real time, anytime, anywhere enabling User transaction approval and User authentication in Issuer controlled environment that was previously not possible.

= Providing Users of Payment and Identification instruments with the ability to review and approve transactions and enter UVMs at the devices they control improves the security of UVM and effectively externalizes User Transaction approval and User authentication from POA / acceptor's environment thus removing the line between User (Cardholder) Present and User (Cardholder) Not Present transactions.

= User Transaction approval and User authentication naturally belong to Issuer environment. Ensuring this decouples the Payment Instrument information (processed in authorization request/response) from User Authentication information which significantly contributes to fraud prevention.

BRIEF SUMMARY OF THE INVENTION

The invention accounts for legacy or non-legacy real time processing systems providing transaction details captured at a POA to the Issuer Host through an Acquirer and when appropriate Network environment in the form of transaction authorization request. At a minimum the Transaction authorization request provides Payment or Identification Instrument ID (i.e. Primary Account Number), POA information (i.e. Acceptor Name and Location) and Transaction Amount.

The invention introduces two components:

= UPAAS User Gateway (125) implemented in Issuer controlled environment which facilitates processing of Approval Request/Response between Issuer Card, Card-less or ID
Legacy systems and UPAAS User Application (122).

= UPAAS User Application (122) which can be implemented on any device supporting appropriate data communication protocol such as TCP/IP. It provides Users with User Positive Approval & Authentication Services Inventors: Branislav R Sikljovan, Guelph, ON, Canada, Radosav Andric, Toronto, ON, Canada ability to review and accept or decline the transaction once the authorization request is received by the Issuer. The User confirms acceptance of a transaction by entering UVM
which is encrypted by the UPAAS User application and forwarded to Issuer for User authentication and Issuer approval.

The invention externalizes User Authentication from a legacy POA, Acquiring and Network systems and enables Issuers of Retail Payment and Identification instruments with ability to positively authenticate Users of these instruments in real time in Issuer controlled environment without any involvement of POA, acquiring and network systems in User authentication.

The invention externalizes User transaction approval from a legacy POA and enables Issuers of Retail Payment and Identification instruments with ability to request a transaction approval from Users in real time after the Issuer receives authorization request for the transaction and before the Issuer approval is granted. As a result of this the invention makes the Issuer approval contingent to the User's approval ensuring non-repudiation of Issuer approved transactions.

The invention provides Users of Retail Payment and Identification instruments with the ability to review and approve or decline transaction and capture UVM on self controlled devices, thus decoupling Point of (Instrument) Acceptance from Point of Transaction Approval and Point of User Authentication, which effectively removes the line between User Present and User Not-Present transactions.

By externalizing User Authentication from the POA the invention ensures that the Payment Instrument information (i.e. Primary Account Number) and User Verification information (i.e. PIN) are neither captured nor processed together at any point of the transaction life cycle. This prevents the association of the Instrument and UVM
information by anyone but the User and Issuer, thus reducing the possibility of creating and using the counterfeit instruments.

User Positive Approval & Authentication Services Inventors: Branislav R Sikljovan, Guelph, ON, Canada, Radosav Andric, Toronto, ON, Canada The major benefits of the invention are the following:

= No physical changes or modifications are required to devices where the UPAAS
User Application is implemented.

= Issuer performs User Authentication in its own environment which is currently possible for ATM on-us transactions only. The same increases transaction security and simplifies implementation and change management: any modification or improvements can be done without impacts to Merchant, Acquirer and Network environments.

= Acceptors of Payment or Identification instruments are spared from implementing and maintaining User Authentication functions at their POA devices while enjoying increased guarantee of payment and non-repudiation.

= Acquirer processors and Networks are spared from implementing and maintaining Industry mandates related to User authentication and data security standards including but not limited to secure UVM capture, encryption and support of associated key infrastructure.

= Users are provided with the opportunity to review and approve or decline the transaction in a self controlled environment and the ability to identify and decline a fraudulent or incorrectly processed transaction request before it is processed by the Issuer Host.
