Solution Overview

Problem

Mobile devices with inadequate security measures are vulnerable to unauthorized access, as traditional security methods like fingerprint recognition and numerical passcodes are being circumvented, posing a risk to data integrity and server-side infrastructure.

Innovation Solution

A system that calibrates a mobile device to unlock only when it detects a specific resonance frequency emitted by a trusted surface, matching a stored resonance frequency, using a tone transmission and frequency response comparison to grant or deny access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional security measures (password protection, fingerprint recognition) are implemented on mobile devices, then user authentication is enabled, but these security measures are being circumvented by security attacks

Engineering Contradiction:
Improvesecurity protectionVSAvoidsecurity breaches
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses acoustic vibrations transmitted through surfaces to create a unique resonance fingerprint for authentication. The mobile device emits acoustic signals that interact with the physical surface, and the resulting vibrations are analyzed to verify the device's location, providing security that cannot be easily replicated or circumvented by traditional digital attacks

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The patent introduces an intermediary physical surface as a mediator between the user and the device authentication process. Instead of directly authenticating the user, the system uses the physical surface the device rests on as an intermediate verification layer, adding a new dimension of security that is independent of traditional digital authentication methods

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If resonance frequency authentication is implemented, then security is enhanced against unauthorized access, but device complexity increases

Engineering Contradiction:
Improvesecurity protectionVSAvoidauthentication system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent leverages existing multi-functional components in mobile devices (speakers for acoustic output, microphones for acoustic input, processors for signal analysis) to implement resonance frequency authentication. By making these existing components serve the additional function of acoustic authentication, the system avoids adding significant hardware complexity while achieving enhanced security

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Systems and methods for securing access to a mobile device are disclosed. A method includes: transmitting, by a computer device, a tone to a surface of an object; detecting, by the computer device, a frequency response from the object based on the transmitted tone; determining, by the computer device, that the detected frequency response from the surface of the object conforms to a stored frequency response; and unlocking, by the computer device, the computer device based on the determining.
