Solution Overview

Problem

Existing card activation and authentication methods for financial cards are time-consuming and insecure, often relying on log-in credentials that can be compromised, lacking robust multifactor authentication.

Innovation Solution

A system utilizing near field communication (NFC) between a contactless transaction card and a user device for authenticated cardholder access, employing offline dynamic data authentication protocols to verify digital signatures and cardholder identity, enabling multifactor authentication and secure activation of cards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If log-in credentials (username and password) are used for authentication, then account access can be confirmed, but security is compromised if credentials are stolen or compromised

Engineering Contradiction:

Improveauthentication securityVSAvoidcredential compromise risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The authentication process is segmented into multiple independent factors: something the user knows (PIN), something the user has (contactless card), and something the user is (biometric data). Each factor is verified separately through distinct technical mechanisms, so compromise of one factor does not lead to complete authentication failure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system uses composite authentication by combining multiple authentication methods (contactless card detection, biometric scanning, PIN verification) into a unified authentication protocol. This composite approach creates layered security where each layer provides additional protection against credential compromise.

Inventive Principle:

Principle #40Composite materials

2Productivity

If traditional card activation methods (telephone or website) are used, then card activation can be achieved, but the process is time-consuming

Engineering Contradiction:

Improvecard activation speedVSAvoidactivation time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The card activation process is transformed into a self-service operation where the contactless card itself participates in the authentication and activation process. The card's embedded credentials enable it to verify its own legitimacy through contactless communication with the processing system, eliminating the need for manual verification steps.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Authentication credentials are pre-loaded into the contactless card during manufacturing, enabling immediate authentication and activation capability. The card arrives pre-configured with security credentials that allow it to participate in the authentication process from the moment of receipt, eliminating setup time.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If contactless card authentication is implemented, then security is enhanced through multifactor authentication, but device complexity increases

Engineering Contradiction:

Improveauthentication securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The contactless card serves multiple functions: it acts as an authentication credential, a security token, and a carrier of account information. This multi-functionality reduces the need for separate devices or systems for each function, thereby managing complexity while enhancing security.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The contactless card acts as an intermediary between the user and the authentication system. It contains embedded credentials that mediate the authentication process by providing verifiable proof of cardholder identity without requiring direct access to sensitive authentication data, simplifying the overall system architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method including receiving a first application user credential associated with a user profile; comparing, for a first match, the first application user credential with a stored second application user credential, wherein the stored second application user credential is associated with a user identity; and responsive to finding a first match, verifying the user identity by performing the following: communicating with a card using near field communication; receiving a public key of a key pair of the card and cardholder identification information of an account holder of the card; instructing the card to generate a digital signature; receiving the digital signature from the card; verifying the digital signature using the public key; and comparing, for a second match, at least a portion of the user identity with at least a portion of the cardholder identification information.
