Mobile Device Proximity Verification Password Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of verification passwords in mobile transactions, such as transportation and delivery services, is inconvenient as it requires users to access their mobile devices to retrieve passwords, leading to potential delays and difficulties in locating the password, especially when transactions occur hours or days prior to service completion.
Innovation Solution
A mobile device system that automatically communicates verification passwords based on device context information like location, proximity to service provider devices, and stationary duration, using a combination of sensors like UWB, RFID, and NFC modules to determine proximity and verify transaction engagement, allowing passwords to be sent automatically to service providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If verification passwords are used to provide additional security for mobile transactions, then security is improved, but user convenience deteriorates as users must access their mobile devices to retrieve passwords
Solution Approach 1:
The system enables automatic password transmission without user intervention. The mobile device automatically detects proximity to the service provider device and transmits the verification password through NFC, RFID, or UWB communication, eliminating the need for users to manually access and share their passwords while maintaining security
Solution Approach 2:
The patent introduces proximity detection technology (NFC, RFID, UWB) as an intermediary mechanism between the user and the service provider. This intermediary automatically handles the password transmission process based on detected proximity, resolving the contradiction between security requirements and user convenience
2Reliability
If users manually retrieve verification passwords from mobile devices, then security is maintained, but transaction time increases due to delays in locating and communicating passwords
Solution Approach 1:
The verification password is prepared and stored in advance in the mobile device before the transaction occurs. When the user approaches the service provider, the system automatically transmits the pre-prepared password, eliminating the time delay associated with locating and retrieving the password during the transaction
Solution Approach 2:
The system performs automatic password transmission without requiring user action to locate or communicate the password. The mobile device autonomously detects proximity and initiates password transmission, significantly reducing transaction time while maintaining security
3Ease of operation
If verification passwords are transmitted automatically based on proximity detection, then user convenience is improved, but device complexity increases due to additional sensors and communication modules
Solution Approach 1:
The mobile device utilizes existing multi-functional components (NFC, RFID, UWB modules) that serve both proximity detection and password transmission purposes. By leveraging these universal components, the system achieves automatic password transmission without significantly increasing overall device complexity
Solution Approach 2:
The patent combines proximity detection and password transmission functions into a single integrated process. The same communication modules (NFC, RFID, UWB) that detect proximity also transmit the verification password, eliminating the need for separate dedicated hardware and reducing overall system complexity
4Reliability
If users access mobile devices to retrieve verification passwords, then security control is maintained, but productivity decreases as users cannot simultaneously use devices for other activities
Solution Approach 1:
The mobile device autonomously handles the security verification process by automatically detecting proximity and transmitting the verification password without user intervention. This allows users to maintain security control while simultaneously engaging in other activities, thereby improving productivity

AI summary
A method includes detecting proximity between a mobile device and a remote device associated with a transaction reserved by a user of the mobile device and a mode of the electronic device. A verification password is sent to the remote device responsive to detecting the proximity and the mode. A device includes a module to detect proximity between the device and a remote device associated with a transaction reserved by a user of the device occurring within a predefined distance threshold and a processor coupled to the module. A device includes another module to detect a stationary mode of the electronic device occurring for at least a predefined duration threshold. The processor is sends a verification password to the remote device responsive to detecting the proximity and the mode.
