Trigger Verification Mechanism for Unauthorized Device Access Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital rights management systems fail to accurately identify intended device targets for triggers, leading to incorrect operations and potential hacker attacks, as devices within a domain can intercept and misuse triggers due to shared domain keys.
Innovation Solution
Incorporating a verification mechanism that checks the related information within triggers, such as device IDs or signatures, to ensure that only the intended device performs the triggered operation, preventing unauthorized actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices within a domain share a common domain key for authentication, then any device can be triggered to perform operations, but any device can also intercept and misuse triggers intended for other devices
Solution Approach 1:
The patent segments the trigger authentication mechanism by incorporating a unique device identifier (such as device ID or IMEI) into each trigger message. This segmentation ensures that while devices share domain-wide authentication capabilities, each trigger is specifically targeted to a particular device, preventing interception and misuse by other devices in the domain.
2Productivity
If a device processes all received triggers without verification, then trigger processing is simple and fast, but incorrect operations occur when triggers are intended for other devices
Solution Approach 1:
The patent applies preliminary action by requiring the device to verify the device identifier in the trigger message against its own identifier before executing the trigger operation. This verification step is performed in advance of the actual trigger execution, ensuring that only intended triggers are processed while maintaining efficient processing of valid triggers.

AI summary
A method for triggering a device to perform an operation is disclosed according to embodiments of the present disclosure. The method includes receiving, by a second device, a trigger containing related information of a target device sent by a first device; and performing an operation triggered by the trigger when the second device determines based on the related information that the second device is the target device. A communication device and a communication system are also disclosed according to embodiments of the present disclosure. By verifying if the trigger received is the trigger intended to be sent to the current device, the present disclosure may prevent a hacker from utilizing a trigger to attach devices.
