Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for accessing content across electronic devices are often inefficient and insecure, requiring specific devices and unlocking processes, which limits flexibility and security.
Innovation Solution
A method and system for remotely accessing a locked device's application interface or content based on predefined criteria, allowing or denying access based on satisfaction of specific conditions, and implementing secure authentication and access control mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional device unlocking and access control techniques are used, then security is maintained through authentication, but device complexity and ease of operation deteriorate due to multiple unlocking steps and device-specific requirements
Solution Approach 1:
The patent implements a universal access control system where a single authenticated device can access applications across multiple different devices without requiring separate unlocking procedures for each device. The access control mechanism works universally across device types (smartphones, tablets, wearables) and application types, eliminating the need for device-specific access protocols while maintaining security through centralized authentication and policy enforcement.
Solution Approach 2:
The patent extracts the authentication and access control functionality from individual device locking mechanisms into a separate, dedicated access control system. This extracted system handles authentication independently and makes authorization decisions based on predefined policies, separating the security function from the device's native locking mechanism and reducing overall system complexity.
2Reliability
If device-specific access requirements are enforced, then security is improved by ensuring proper authentication, but ease of operation deteriorates due to restrictions on which devices can access content
Solution Approach 1:
The patent implements dynamic access control policies that can adapt to different contexts, users, and devices in real-time. Access permissions are not statically defined but dynamically determined based on current device state, user behavior patterns, security context, and policy rules. This allows the system to provide flexible access to authorized devices while maintaining security through context-aware authorization decisions.
Solution Approach 2:
The patent introduces an intermediary access control service that mediates between authenticated users and target applications across different devices. This intermediary layer handles the complexity of access control logic, policy evaluation, and authorization decisions, shielding users from complexity while providing flexible access. The intermediary translates security requirements into actionable authorization decisions without requiring users to understand underlying security mechanisms.
3Reliability
If multiple authentication steps are required for cross-device access, then security is enhanced, but productivity deteriorates due to time-consuming authentication processes
Solution Approach 1:
The patent performs preliminary authentication and device trust establishment in advance, creating pre-approved access relationships between devices. When a user wants to access an application on another device, the system checks pre-established trust relationships and applies predefined policies, eliminating the need for repeated full authentication cycles. This preliminary action maintains security while dramatically reducing access time for authorized operations.
Solution Approach 2:
The patent implements a mechanism to skip redundant authentication steps for devices that have already been authenticated and have active access permissions. The system rapidly validates existing authentication tokens and permission states, allowing authorized access to proceed quickly without re-performing complete authentication sequences. This skipping mechanism maintains security by validating existing credentials while rushing through the access process for authorized users.
