Ambient Wireless Access Gateway for Secure Internet Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for accessing ambient wireless devices are limited to short-range communication and do not support a layered networking model, preventing their use in Transmission Control Protocol/Internet Protocol (TCP/IP) based remote access.
Innovation Solution
An Ambient Device Management (ADM) system that utilizes a first communication protocol (e.g., TCP/IP) for user devices and a second protocol (e.g., near field communication) for ambient devices, facilitated by an ADM server that manages connections and grants access to data from ambient devices over the internet.

Engineering Contradiction Analysis
1Length of moving object
If conventional short-range communication methods are used to access ambient wireless devices, then power consumption is minimized and security is maintained, but communication range is limited and remote access over the internet is prevented
Solution Approach 1:
The patent introduces a gateway device as an intermediary between ambient wireless devices and remote user devices. The gateway runs a protocol converter that translates between the simple short-range protocol used by ambient devices and the TCP/IP protocol used by remote devices, enabling long-range communication without modifying the ambient devices themselves
Solution Approach 2:
The system segments the communication architecture into distinct layers: ambient devices using simple short-range communication, gateway devices handling protocol conversion and internet connectivity, and user devices accessing data remotely. This segmentation allows each component to operate at its optimal complexity level
2Adaptability or versatility
If ambient devices support layered networking model for TCP/IP based remote access, then internet access is enabled, but device complexity increases and power efficiency decreases
Solution Approach 1:
The gateway device serves as an intermediary that handles all complex TCP/IP networking and internet communication. Ambient devices only need to support simple short-range protocols, offloading all networking complexity and associated power consumption to the gateway device
Solution Approach 2:
The gateway device provides self-service by autonomously handling protocol conversion, connection management, and data routing between ambient devices and remote users without requiring sophisticated networking capabilities from the ambient devices themselves
3Reliability
If multiple message exchanges are used in secure transactions with ambient devices, then security is enhanced, but power consumption increases
Solution Approach 1:
The system implements selective security measures where full multi-message secure transaction protocols are only used when necessary (e.g., initial connection establishment or sensitive operations), while routine operations use simplified protocols to minimize power consumption
Solution Approach 2:
The protocol converter dynamically adjusts security parameters and message exchange complexity based on the specific transaction requirements, ambient device power state, and security risk level, optimizing the balance between security and power consumption

AI summary
A system and method of secure transactions with ambient wireless devices. The method includes receiving, from a user device via a first communication protocol, a request for data associated with a second device. The method includes determining, based on the request, a capability of a first device to access the data from the second device via a second communication. The method includes sending, by one or more processors to the first device via the first communication protocol, a message to cause the first device to access the data from the second device using a second communication protocol and send the data to the processing device using the first communication protocol. The method includes granting or denying the user device with access to the data.
