Solution Overview

Problem

Users face uncertainty when trusting online reviews due to the prevalence of fake reviews, which can positively or negatively impact sales, making it difficult to verify if the reviewer actually experienced the product or service.

Innovation Solution

A system utilizing contactless cards that encrypt data using a cryptographic algorithm and private key, allowing an authentication server to verify the card's usage in transactions, thereby confirming the reviewer's experience and enabling the submission of verified reviews.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fake reviews are allowed to be posted freely, then the quantity of reviews increases and user engagement improves, but the reliability and trustworthiness of reviews deteriorates

Engineering Contradiction:
Improvereview trustworthinessVSAvoidverification system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an authentication server as an intermediary between the review submission system and the contactless card verification system. This server receives encrypted data from contactless cards, decrypts it using stored private keys, and validates transaction information before allowing review submission. The intermediary handles the complex cryptographic operations and transaction verification, keeping the review platform itself relatively simple while ensuring review authenticity through the mediating authentication layer.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If contactless card verification is implemented, then the reliability of reviews is improved, but the ease of operation deteriorates due to additional authentication steps

Engineering Contradiction:
Improvereview verificationVSAvoidreview submission process
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system enables self-service verification by requiring users to simply tap their contactless card to their mobile device, which automatically performs the authentication and transaction verification without manual intervention. The contactless card itself stores the necessary cryptographic credentials and transaction data, allowing the verification process to be initiated and completed through a simple tap action rather than requiring users to manually provide identification or transaction details.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The authentication server performs preliminary actions by storing private keys and transaction information in advance before review submission is needed. When a user taps their contactless card, the system already has the encrypted data and transaction records ready for rapid verification. This preliminary preparation of authentication credentials and transaction data enables fast verification without adding significant time to the review submission process.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If cryptographic verification using contactless cards is used, then the measurement precision of user identity and transaction verification is improved, but the device complexity increases due to cryptographic algorithms and secure key storage

Engineering Contradiction:
Improveidentity verification accuracyVSAvoidcryptographic system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the cryptographic verification system into distinct functional components: the contactless card stores encrypted data and transaction information, the mobile device handles data transmission and initial processing, and the authentication server performs decryption and validation. This segmentation distributes the cryptographic complexity across multiple devices, with each device responsible for specific cryptographic operations, thereby achieving high verification precision without requiring any single device to handle all cryptographic functions.

Inventive Principle:
Principle #1Segmentation

AI summary

Systems, methods, articles of manufacture, and computer-readable media for verified reviews. An application may receive an indication to generate a review. An application programming interface (API) of the application may receive, from a communications interface of a contactless card, encrypted data generated by the contactless card. The API of the application may transmit, to an authentication server: the encrypted data, an indication of the application, and an identifier associated with the entity. The API of the application may receive indications specifying that the authentication server decrypted the encrypted data and determined that the contactless card was used to make a purchase with the entity. The application may permit, based on the indications received from the authentication server, generation of the review. The application may publish the review to one or more review platforms associated with the application.
