Solution Overview

Problem

Users face challenges in securely managing numerous passwords across different online platforms, often resorting to insecure methods like writing them down, which compromises security.

Innovation Solution

A system that stores passwords using a Master Encryption Key derived from user-defined prompt-character string associations, allowing users to remember only one set of associations for multiple passwords, enhancing security by using complex passwords without needing to recall them.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users store passwords in unsecure manners (written in unencrypted files), then users can easily remember which password is tied to which site, but security is significantly undermined

Engineering Contradiction:
Improveease of password retrievalVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a password management system as an intermediary between the user and multiple passwords. The system stores passwords in an encrypted database and uses a master encryption key (derived from a single memorable passphrase) to decrypt and manage multiple passwords, eliminating the need for users to store passwords in insecure plain-text files while maintaining easy access through automated retrieval

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the password management function into distinct components: a master encryption key derivation module that converts a single passphrase into multiple encryption keys, an encrypted password database for secure storage, and an automated retrieval system. This segmentation allows secure storage while maintaining ease of access through the coordinated operation of these separate modules

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If users remember numerous passwords for different sites, then users can access multiple online platforms, but the complexity and burden of memorization increases

Engineering Contradiction:
Improveability to access multiple platformsVSAvoidcognitive load
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal password management system where a single passphrase serves multiple functions: it derives the master encryption key, enables decryption of the password database, and facilitates access to numerous different online platforms. This multi-functionality eliminates the need for users to separately remember each password while maintaining the ability to access multiple platforms

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent creates a centralized copy of all passwords in an encrypted database, which the system automatically retrieves and provides to applications as needed. Users interact with a single copy (the passphrase) rather than needing to remember multiple password copies, significantly reducing cognitive load while maintaining platform access capability

Inventive Principle:
Principle #26Copying

3Reliability

If users use complex passwords for each application, then security is improved, but users cannot remember these complex passwords

Engineering Contradiction:
ImprovesecurityVSAvoidease of password recall
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a self-service system where the password management software automatically generates, stores, and retrieves complex passwords for multiple applications. The system uses a single user-defined passphrase to derive encryption keys that protect the stored passwords, allowing users to maintain complex passwords for security while the system handles the burden of management and retrieval

Inventive Principle:
Principle #25Self-service

AI summary

The systems, methods and apparatuses described herein provide a computing environment for authenticating a user. An apparatus according to the present disclosure may comprise a non-volatile storage, a user interface, and a password engine. The password engine is configured to retrieve two or more predetermined prompts from the non-volatile storage, present the two or more predetermined prompts on the user interface to a user in a random order, receive a first set of input(s) in response to the two or more predetermined prompts, create an encryption keyword from the received first set of input(s) according to an original order of the two or more predetermined prompts stored in the non-volatile storage, and use the encryption keyword to authenticate the user.
