Pre-authenticated Link for Private Data Feed Access

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional data feed technologies lack user control over private information publication, fail to authenticate users securely, and do not allow seamless authentication across devices, leading to insecure and inconvenient access to private data.

Innovation Solution

A pre-authenticated link is generated with a token that identifies the authorized user, private feed, and owner, enabling access without re-entering authentication information, and allowing access even when logged out, using a unique key that can revoke access and manage permissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional public data feed is used, then data aggregation is enabled, but user control over private information publication is lost

Engineering Contradiction:

Improvedata aggregation capabilityVSAvoiduser control over private information

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the data feed into public and private portions, allowing selective authentication and access control. The private data feed is separated from the public feed, enabling users to control access to specific portions of their data while maintaining public aggregation capabilities for other content.

Inventive Principle:

Principle #1Segmentation

2Reliability

If basic authentication with username and password is used, then user authentication is achieved, but security risk increases due to plain text transmission

Engineering Contradiction:

Improveuser authenticationVSAvoidsecurity risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical authentication system (username/password entry) with an automated token-based system. The authentication module automatically provides tokens to authenticated users, eliminating the need for manual credential entry and reducing security risks associated with plain text transmission of authentication information.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If basic authentication is used, then authentication is achieved, but authentication cannot be transferred between devices

Engineering Contradiction:

ImproveauthenticationVSAvoiddevice transferability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal authentication token that functions across multiple devices. The token generated during authentication on one device can be used to access the user's private data feed on other devices without requiring re-authentication, making the authentication system multi-device compatible while maintaining security.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If user must be constantly logged on to access private information, then access is maintained, but account security risk increases

Engineering Contradiction:

Improvecontinuous accessVSAvoidaccount security risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent performs preliminary authentication and generates access tokens in advance. These tokens are stored and automatically provided to the user when needed, allowing access without requiring the user to remain continuously logged on. This eliminates the security risk of keeping authentication sessions active while maintaining convenient access.

Inventive Principle:

Principle #10Preliminary action

5Object-affected harmful factors

If manual authentication entry is required each time, then authentication security is maintained, but user convenience decreases

Engineering Contradiction:

Improveauthentication securityVSAvoiduser convenience

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent implements a self-service authentication system where the authentication module automatically provides tokens to authenticated users without requiring manual intervention. The system manages authentication credentials and token distribution automatically, maintaining security while eliminating the inconvenience of repeated manual authentication entry.

Inventive Principle:

Principle #25Self-service

AI summary

A method of generating a pre-authenticated link to access a private feed and providing access to the private feed using the pre-authenticated link. A request to access the private feed is received and a first user sending the request is authenticated. A token for the first user is generated when the first user is authorized to access the private feed. The token may identify the first user, the private feed and an owner of the private feed. The token may be embedded within a link and transmitted to the first user. A user is automatically authorized to access the private feed when the token is sent by the user using the link. The link automatically authenticates the first user and allows access to the private feed. The private feed may become inaccessible to the first user when the owner of the private feed revokes access of the first user.
