Appliance Cloud Provisioning via Portable Device Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for connecting household appliances to cloud computing systems are complex and vulnerable to IT security risks during the provisioning process, with potential for fraudulent interception of provisioning data.
Innovation Solution
A method and system that utilize a portable communication device to connect a household appliance to a cloud computing system by storing and verifying unique security codes, including a first code and a second code, to authenticate and authorize the connection, thereby enhancing IT security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing provisioning systems are used to connect household appliances to cloud computing systems, then the connection process can be completed, but the system complexity increases and security vulnerabilities remain during provisioning operations
Solution Approach 1:
A portable communication device serves as an intermediary between the household appliance and the cloud computing system during provisioning. The device receives provisioning data from the appliance, transmits it to the cloud system, and receives authentication responses back to the appliance. This intermediary approach simplifies the direct connection complexity while maintaining security through verified authentication channels.
Solution Approach 2:
Security codes are pre-stored in both the household appliance and the cloud computing system before the provisioning process begins. The appliance contains a first security code and the cloud system contains a second security code that corresponds to the first code. This preliminary preparation of authentication credentials enables secure verification during provisioning without adding operational complexity.
2Reliability
If provisioning data is exchanged between household appliance and mobile device during provisioning steps, then connection authentication can be performed, but the data remains vulnerable to fraudulent interception by unauthorized users
Solution Approach 1:
The system implements a feedback mechanism where the cloud computing system sends a second security code back to the household appliance after receiving the first security code. The appliance then verifies this feedback code against its stored expected value. This feedback loop ensures that only authenticated data exchanges are permitted, preventing fraudulent interception by unauthorized users who cannot provide the correct feedback code.
3Reliability
If multiple security code verifications are implemented during provisioning, then IT security is enhanced, but the connection process becomes more complex
Solution Approach 1:
The household appliance automatically performs security code verification without requiring user intervention. The appliance compares the received second security code with its stored expected value internally, and the cloud system automatically authorizes or prevents connection based on the verification result. This self-service approach maintains multiple verification steps for security while keeping the user experience simple.

AI summary
A method for connecting an appliance to a cloud computing system by a portable communication device is disclosed herein. The method may include storing in said appliance and said cloud computing system a first code and a second code associated with said appliance, communicating said first code stored in said appliance to said cloud computing system via said portable communication device, comparing said first code of said appliance with said first code of said cloud computing system, communicating said second code of said cloud computing system to said appliance when said first code received from said portable communication device corresponds to said first code of said cloud computing system, verifying a first security condition when said second code received from said cloud computing system corresponds to said second code of said appliance, and authorizing or preventing a connection between said appliance and said cloud computing system based on the result.
