Digital Key Authentication With Timing-Based Operation Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user information devices lack reliable security mechanisms to protect secret and private data from unauthorized access, particularly in scenarios where remote hacking can exploit insufficient authentication methods.
Innovation Solution
A digital key device with a casing, input device, and controlling unit that requires timing-based user operation inputs, such as gestures or audio signals, to authenticate and authorize data access, incorporating a double verification process to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional authentication methods (PIN, passwords) are used, then ease of operation is improved, but reliability of security is worsened
Solution Approach 1:
The authentication process is segmented into multiple independent verification stages: first verifying the personal identification number, then separately verifying the timing-based operation input. This segmentation ensures that each authentication factor is independently validated, preventing a single point of failure and significantly improving security reliability while maintaining operational ease through automated multi-factor verification.
2Ease of operation
If remote access is enabled, then ease of operation is improved, but object-generated harmful factors are worsened
Solution Approach 1:
The timing-based operation verification acts as an intermediary security layer between the user and the data access system. When a user attempts access (especially remote access), the system requires not only credentials but also a timing-based operation input that must be performed within a specific time window. This intermediary verification mechanism allows convenient remote access while blocking automated hacking attempts that cannot replicate the timing-based human interaction.
3Reliability
If multiple verification procedures are implemented, then reliability is improved, but device complexity is worsened
Solution Approach 1:
The controlling unit is designed with multi-functionality to handle diverse authentication methods (personal identification number verification, timing-based operation verification) within a single integrated system. The data storage unit similarly serves multiple purposes: storing personal identification numbers, storing timing-based operation sets, and managing authentication states. This universal design consolidates what could be separate complex components into unified multi-functional units, improving reliability through comprehensive verification while controlling overall system complexity.

AI summary
A digital key service device (10) includes a casing (100), an input device (101), a data storage unit (102) and a controlling unit (103). The input device (101) is disposed near the casing (100) or mounted on the casing (100), and configured to receive a user operation input. The data storage unit (102) is disposed in the casing (100), and configured to store digital data and a digital key. The controlling unit (103) is disposed in the casing (100), and configured to use the digital key to perform a digital key service or output the digital data to a host (11) when authentication is complete. The authentication includes an operation verification procedure for verifying the user operation input. The authentication is complete when the controlling unit (103) determines that the user operation input conforms to a preset timing-based input set.
