IP Address Authentication for Web Session Security

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current web security systems rely on logical authentication methods that can be intercepted and compromised, lacking physical verification of the client device's location, which is essential to distinguish genuine users from third parties.

Innovation Solution

A system that combines logical security processing of login and password data with physical security processing of Internet Protocol (IP) addresses to authenticate client devices during server sessions, ensuring that the IP address associated with the user remains consistent throughout the session.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If login and password systems are used for authentication, then user identity verification is provided, but security information can be intercepted by third parties

Engineering Contradiction:

Improveuser authenticationVSAvoidpacket interception

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments authentication into two independent parts: logical authentication (login/password) and physical authentication (IP address verification). This segmentation allows each layer to address different security aspects, with IP address verification providing an additional barrier against interception attacks that cannot easily compromise both layers simultaneously.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces IP address as an intermediary verification mechanism between the user and the server. The server uses the IP address as a mediator to independently verify the physical origin of requests, creating a trusted reference point that cannot be easily spoofed or intercepted along with the login credentials.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If encrypted certificate services are used to verify sending machines, then physical device verification is provided, but browser setup and usage complexities increase

Engineering Contradiction:

Improvedevice verificationVSAvoidbrowser setup

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent makes the system self-service by automatically extracting and verifying the client's IP address from incoming requests without requiring any user action. The server autonomously performs physical authentication by comparing the current IP address against the stored reference IP address, eliminating the need for users to manually configure certificates or modify browser settings.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent uses the IP address, a readily available and inexpensive piece of information already present in every network request, as the verification mechanism. This disposable, easily obtainable data point replaces complex encrypted certificate systems, providing effective device verification without adding operational complexity for users.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A system and method for providing security for an Internet server. The system comprises: a logical security system for processing login and password data received from a client device during a server session in order to authenticate a user; and a physical security system for processing Internet protocol (IP) address information of the client device in order to authenticate the client device for the duration of the server session.
