Vehicle Locking System Using Dynamic Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle locking and unlocking methods using code inputs are vulnerable to theft as the code can be easily observed, allowing unauthorized access.
Innovation Solution
A method utilizing a mobile device to communicate with a server for generating and sending a temporary code for locking and unlocking a vehicle, which can be input via various devices such as sensors, cameras, or touch-sensitive fields, ensuring secure and convenient access without the physical key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed code is programmed in the vehicle for locking and unlocking, then the vehicle can be accessed without a physical key, but the code can be easily observed and stolen by unauthorized persons
Solution Approach 1:
The patent implements dynamic codes that change over time or after each use, transforming the static security system into a dynamic one. The code is generated based on time stamps, random values, or usage counters, ensuring that each code is unique and cannot be reused, thereby preventing theft while maintaining ease of access for authorized users
Solution Approach 2:
The patent changes the parameter of code validity from permanent to temporary. The code includes time-based expiration or usage-based limitations, so that even if observed, the code becomes invalid after a short period or single use, significantly reducing the risk of unauthorized access
2Adaptability or versatility
If a code is used for locking and unlocking the vehicle, then extensive functions can be enabled, but the code input process can be spied on by observing door handle pulling or button tapping
Solution Approach 1:
The patent introduces an intermediary verification process where the code is not simply compared but validated through multiple factors including time stamps, device identifiers, and server verification. This intermediary layer prevents simple observation from leading to unauthorized access, as the system verifies the authenticity and timing of each code submission
Solution Approach 2:
The patent uses digital copies of authentication data stored securely in the vehicle's memory, comparing the submitted code against these stored references. The system creates and stores multiple valid code variations, allowing legitimate users access while preventing unauthorized replication through observation
3Reliability
If a mobile device and server communication is used to generate temporary codes, then security is improved, but the system complexity increases
Solution Approach 1:
The patent leverages the mobile device's existing universal capabilities (communication, computing, timekeeping) to generate and verify codes, rather than requiring specialized hardware. The vehicle's existing communication systems are also utilized for server interaction, reducing the need for additional dedicated components and minimizing system complexity
Data Source
AI summary
A method for locking and/or unlocking a vehicle having an input device for a code on the vehicle, via which the vehicle can be locked and/or unlocked, involves requesting the code via a mobile device having a mobile number registered to the respective vehicle with a data server. After the request, the data server generates a current code and send this to the mobile device and to the vehicle. The code can then be input via the input device and compared to the code sent to the vehicle and, should they match, locking and/or unlocking of the vehicle is enabled.
