Audio Verification for Contactless Delivery Proximity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current online delivery systems face challenges in verifying physical delivery of items, especially in contactless scenarios where traditional methods like signature verification are not feasible, leading to potential errors or fraud.
Innovation Solution
The implementation of audio verification using mobile devices to play and detect a verification code, ensuring that the customer and picker are within proximity, thereby confirming delivery without requiring direct physical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional signature verification is used, then delivery verification reliability is improved, but ease of operation deteriorates because it cannot be performed contactless or without direct customer presence
Solution Approach 1:
The patent replaces the mechanical signature verification process with an acoustic verification system. The picker's mobile device plays an audible verification code that the customer's mobile device captures through its microphone, converting a physical interaction requirement into an acoustic signal transmission that can occur contactlessly.
Solution Approach 2:
The patent introduces audio verification codes as an intermediary mechanism between the picker and customer. Instead of direct physical signature exchange, the verification code serves as a mediator that confirms proximity and identity through acoustic transmission, enabling verification without direct contact or presence.
2Ease of operation
If audio verification is implemented, then contactless verification capability is improved, but device complexity increases due to audio playback and detection requirements
Solution Approach 1:
The patent leverages the existing multi-functionality of mobile devices, which already possess audio playback capabilities (speakers) and audio detection capabilities (microphones). By utilizing these pre-existing components for verification purposes, the system avoids adding dedicated hardware while achieving contactless verification.
Solution Approach 2:
The mobile devices themselves perform the verification function using their own built-in audio components. The picker's device plays the verification code and the customer's device captures it, with both devices serving their own verification roles without requiring external verification equipment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method reduces the likelihood of errors and fraud by establishing the proximity of the customer and picker at the time of delivery, enhancing the reliability of the delivery verification process.
Implementation Method 1
a customer or picker's mobile device plays verification audio including a verification code specific to the order
Implementation Method 2
the other party's mobile device can detect the verification audio through a microphone and decode the verification code from the captured audio
Data Source
AI summary
When an online system receives an order from a customer, the online system can fulfill the order (for example, using a picker to acquire and deliver the ordered items) and use audio verification to verify delivery. When using audio verification, a customer or picker's mobile device plays verification audio including a verification code specific to the order. If the mobile devices (and, by proxy, the customer and picker) are nearby (for example, within 10 feet), the other party's mobile device can detect the verification audio through a microphone and decode the verification code from the captured audio. In some implementations, audio verification can also be performed using a smart doorbell or smart home without the presence of the customer.
