Solution Overview

Problem

Existing transaction processing systems lack a convenient and secure method for users to manage and execute transactions using a unique identifier that is easy to remember and share, while maintaining privacy and reducing data entry errors.

Innovation Solution

A transaction processing service that utilizes a unique phrase as an identifier for user accounts, allowing users to associate phrases with their accounts, configure rules for content storage and forwarding, and perform transactions with vendors, using these phrases for authentication and command execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users employ traditional authentication methods (usernames, passwords, account numbers), then security and reliability are maintained, but ease of operation and user convenience deteriorate due to complex data entry and memorization requirements

Engineering Contradiction:
Improveease of useVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces traditional authentication credentials (usernames, passwords, account numbers) with a copied or substituted form - a unique phrase that serves the same authentication function. Users can share these phrases instead of sensitive credentials, and the system processes them as valid authentication tokens, thereby simplifying user interaction while maintaining security through the phrase's uniqueness and case-insensitive processing.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent changes the parameter of authentication from traditional structured credentials to free-form phrases. The system performs case-insensitive processing and normalizes the phrases, transforming the authentication parameter from rigid (exact case matching) to flexible (case-insensitive), thereby improving ease of operation while maintaining reliable authentication through consistent normalization and matching logic.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If users share sensitive authentication information, then ease of operation improves by allowing direct sharing, but loss of information and privacy security worsen due to exposure of sensitive data

Engineering Contradiction:
Improveease of sharingVSAvoidprivacy
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent creates a copy or substitute for sensitive authentication information - the unique phrase serves as a safe alternative that users can share freely. Instead of sharing actual credentials, the system uses these phrase tokens that replicate the authentication function without exposing sensitive data, thereby enabling easy sharing while preserving privacy.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The unique phrases function as disposable or replaceable authentication tokens that can be shared without long-term privacy concerns. If a phrase is compromised, users can generate new phrases, making the authentication mechanism resilient and allowing free sharing without permanent exposure of sensitive information.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If users memorize complex account identifiers, then reliability of authentication is maintained, but loss of time and productivity worsen due to difficulty in recall and increased errors

Engineering Contradiction:
Improveauthentication accuracyVSAvoidtime for data entry
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent changes the authentication parameter from complex structured data (usernames with specific formats, passwords with complexity requirements) to simple free-form phrases. The case-insensitive processing and normalization eliminate the need for users to remember exact casing or complex formats, reducing data entry time and errors while maintaining authentication reliability through consistent matching.

Inventive Principle:
Principle #35Parameter changes

4Measurement precision

If the system processes case-sensitive authentication data, then measurement precision and security are improved, but ease of operation deteriorates due to increased user errors and complexity

Engineering Contradiction:
Improveauthentication precisionVSAvoiduser convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent changes the case-sensitivity parameter of authentication from strict (case-sensitive) to flexible (case-insensitive). The system normalizes all phrases to a common case before processing, thereby eliminating user errors related to casing while maintaining precise authentication through consistent normalization and matching logic. This parameter change resolves the contradiction by making the system both precise and user-friendly.

Inventive Principle:
Principle #35Parameter changes

AI summary

Described herein are techniques for employing a phrase as a unique identifier of a user and a corresponding user account. For instance, a transaction processing service may maintain multiple user accounts each associated with respective users. In addition, the transaction processing service may associate one or more unique phrases with each of these respective users and user accounts. Users may then configure rules associated with their respective user accounts to enable use of associated phrases as identifiers for storing a variety of different content in association with the phrases. Users may also configure their accounts with communication rules that instruct the transaction processing service to send pieces of content that are received with the phrase to different specified destinations. Users may also configure their accounts with preferences used by vendors to complete transactions initiated with use of a phrase.
