Authenticated UI Interactions Using Hardware-Verified Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack effective mechanisms to prevent fraudulent access to privacy-related functionality on mobile electronic devices, allowing malicious software to spoof user interface inputs and gain unauthorized access.
Innovation Solution
Implementing a validation system that requires software events to be confirmed by corresponding hardware input events, using cryptographic tokens and verified user interface elements to authenticate interactions, thereby preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software-based events are used to grant access to device functionality, then access control can be implemented, but the system becomes vulnerable to spoofing of user interface inputs
Solution Approach 1:
The patent introduces an authentication token as an intermediary between the software event and the functionality grant. The token is generated by a trusted component (such as a secure enclave or hardware security module) in response to a verified hardware input event, and must be presented and validated before the requested functionality is granted. This intermediary mechanism prevents spoofing because the token can only be generated by the trusted hardware component after verifying the authenticity of the hardware input event.
Solution Approach 2:
The patent replaces the purely software-based access control mechanism with a hybrid system that incorporates hardware-based verification. Instead of relying solely on software events that can be spoofed, the system requires verification against hardware input events through cryptographic validation performed by a trusted hardware component. This substitution of mechanical/software verification with hardware-based verification eliminates the spoofing vulnerability.
2Reliability
If hardware input verification is implemented to prevent spoofing, then security is improved, but system complexity increases
Solution Approach 1:
The patent extracts the complex verification logic and cryptographic operations into a separate trusted component (such as a secure enclave, hardware security module, or dedicated verification daemon). This extraction allows the main application and user interface to remain simple while the complex security verification is handled by the specialized trusted component. The application only needs to request verification and receive the authentication token, without needing to implement the complex verification logic itself.
Solution Approach 2:
The trusted component performs self-service by automatically generating authentication tokens in response to verified hardware input events and validating tokens presented by applications. The verification process is automated and does not require manual intervention or complex configuration by the application developer. The system self-manages the cryptographic operations and token lifecycle, reducing the complexity burden on the overall system.

AI summary
An access control system is provided to prevent the surreptitious granting of access to privacy related functionality on an electronic device. Software-based events to grant access to device functionality can be validated by confirming that the software event corresponds with a hardware input event. This validation prevents the spoofing of a user interface input that may be used to fraudulently grant access to specific functionality.
