Direct Radio Communication for Secure Offline Device Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies require intermediary devices and user input for device discovery and data exchange, limiting the functionality of offline devices and exposing sensitive information.
Innovation Solution
Direct radio signal communication using mid-range to short-range protocols like Bluetooth allows devices to discover and securely exchange information without intermediaries or user input, enabling offline transactions and protecting user privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication uses intermediary devices and requires user input for device discovery and data exchange, then communication security and reliability are improved, but device functionality is limited and user privacy is exposed
Solution Approach 1:
The patent applies the intermediary principle by introducing a payment service system as a mediator that enables direct device-to-device communication without requiring traditional network intermediaries. The payment service system facilitates secure communication between user devices and merchant devices through radio signal exchange, allowing offline transactions while maintaining security through centralized authentication and encryption protocols.
2Adaptability or versatility
If direct radio signal communication is used for device discovery and data exchange, then device functionality and offline capability are improved, but communication security and user privacy protection are worsened
Solution Approach 1:
The patent extracts sensitive user information from direct radio signal transmission by implementing a payment service system that handles authentication and data exchange centrally. User credentials, payment information, and personal data are extracted from the peer-to-peer communication and processed through secure servers, leaving only anonymized device identifiers in the radio signal exchange, thus maintaining functionality while protecting privacy.
Solution Approach 2:
The payment service system acts as an intermediary that mediates between user devices and merchant devices, ensuring that sensitive data does not traverse the wireless channel directly. Authentication tokens and encrypted session keys are exchanged through this intermediary, providing security for direct radio communication without exposing user privacy information.
3Reliability
If user input and pairing processes are required for direct communication, then communication security is improved, but ease of operation and user convenience are worsened
Solution Approach 1:
The patent implements preliminary action by pre-configuring devices with payment service system credentials, authentication certificates, and communication protocols before actual use. When a user initiates a transaction, the system automatically performs authentication, establishes secure channels, and exchanges data without requiring manual pairing or user input for security protocols, thus maintaining security while improving ease of operation.
Data Source
AI summary
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for discovery of and communication with nearby devices using direct radio signal communication. One of the methods includes receiving, by a payment service system, a message authorizing a payment from a user account to a merchant account, wherein the message was sent by a user device using direct radio signal communication to a nearby merchant device and forwarded to the payment service system by the merchant device. The message is decrypted to obtain a session token that authenticates the user device as being associated with the user account. If the session token is valid a payment transaction is conducted between the user account and the merchant account.
