Dynamic Pulse Code Embedding for Real-Time Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital watermarking technologies are inadequate for securing dynamic digital content, as they are static and cannot effectively authenticate authorized users in real-time, nor can they prevent unauthorized access and duplication.
Innovation Solution
A computer-implemented system and method that embeds dynamic pulse codes within content to provide secure real-time communication, certification, and authentication. This system uses a cloud server with a pulse oracle, pulse data manager, and internal database to generate and manage pulse codes, which are embedded and dynamically updated in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static digital watermarking is used for content authentication, then implementation simplicity is maintained, but real-time authentication capability and security against unauthorized access are insufficient
Solution Approach 1:
The patent transforms static digital watermarking into a dynamic system by embedding pulse codes that are continuously updated in real-time. The pulse codes change with each communication session and are synchronized between sender and receiver through cloud infrastructure, providing dynamic authentication that adapts to current security requirements while maintaining system manageability through automated key rotation and session-based validity.
Solution Approach 2:
The patent introduces a cloud-based intermediary system that manages pulse code generation, storage, and synchronization. This intermediary handles the complexity of real-time key management and authentication verification, allowing the endpoint devices to perform simpler local operations while relying on the cloud infrastructure for secure key distribution and session management.
2Reliability
If dynamic pulse codes are embedded in real-time, then authentication security and anti-brute-force capability are improved, but processing complexity and computational requirements increase
Solution Approach 1:
The patent segments the authentication system into distinct functional modules: pulse code generation, embedding, transmission, extraction, and verification. Each module handles a specific aspect of the authentication process, allowing for optimized processing at each stage and distributing computational load across the system architecture, including cloud-based components and endpoint devices.
Solution Approach 2:
The patent performs preliminary actions by pre-generating and storing pulse codes in secure cloud databases before they are needed for authentication. Session keys and pulse code parameters are prepared in advance and made available to authorized users when needed, reducing real-time computational requirements during actual authentication events while maintaining security through controlled access to pre-computed credentials.
3Reliability
If pulse codes are continuously updated and synchronized, then security against replay attacks and brute force is enhanced, but network communication overhead and synchronization requirements increase
Solution Approach 1:
The patent implements periodic updates of pulse codes synchronized to specific events such as session initiation, key rotation intervals, or authentication milestones. Rather than continuous updating, the system refreshes credentials at predetermined intervals and upon specific triggers, reducing network communication overhead while maintaining security through regular credential rotation and time-limited session validity.
4Object-affected harmful factors
If multiple micro-pulse layers are embedded in content, then detection difficulty for hackers increases, but embedding complexity and decoding requirements increase
Solution Approach 1:
The patent embeds multiple layers of pulse codes within each other, creating a nested structure where outer pulse layers contain references to inner layers. This nested arrangement increases security by requiring sequential decoding of multiple layers, with each layer providing additional authentication verification. The nesting structure allows efficient embedding where inner pulses are contained within the data structure of outer pulses, reducing overall overhead.
Data Source
AI summary
A system for establishing a secure communication or authentication in real-time, the system consists of a first computing device and a second computing device, each with a content encoding and decoding module. Each content encoding and decoding module includes a content selection module that allows a user to choose content and send it to a pulse injector, which embeds pulse codes using contextual, user-specific from devices or a cloud/external database. The pulse oracle authenticates and adjusts pulse codes continuously for security. The pulse reader receives content, and sends decoded pulse information to second computing device, establishing secure communication in real time over network.
