Relay-Based Security Breach Notification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Security breaches of user accounts, such as credit cards, lead to unauthorized use due to delayed notification and technical limitations like lack of network access, increasing the risk of unauthorized transactions.
Innovation Solution
A system and method for generating and transmitting security breach notifications through user devices and relay devices to an account repository, even in areas with limited network access, to quickly disable compromised accounts and prevent unauthorized activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user directly notifies the account repository of a security breach, then the notification process is simple and direct, but the user may be unable to transmit the notification promptly due to lack of network access
Solution Approach 1:
A relay device is introduced as an intermediary between the user device and the account repository. The relay device receives security breach notifications from user devices even when they cannot directly communicate with the repository, stores them temporarily, and forwards them when network conditions permit, ensuring reliable delivery without requiring continuous direct network access
Solution Approach 2:
The relay device pre-establishes communication channels and maintains readiness to receive notifications before breaches occur. When a breach is detected, the notification infrastructure is already in place to immediately capture and relay the notification, reducing the time loss between breach discovery and account disabling
2Reliability
If the system waits for direct network access to transmit breach notifications, then network resources are conserved, but the account remains vulnerable to unauthorized use during the delay
Solution Approach 1:
The relay device acts as an energy-efficient intermediary that maintains persistent, low-power communication channels with both user devices and the account repository. It buffers notifications locally using minimal energy resources and batches transmissions when network access is available, reducing the energy cost compared to repeated attempt-by-Attempt direct connections from user devices
Solution Approach 2:
The system uses temporary, lightweight notification messages that are quickly generated, transmitted through the relay, and processed. These disposable notification objects require minimal energy to create and transmit compared to maintaining continuous secure connections, achieving security without excessive energy consumption
3Adaptability or versatility
If multiple relay devices are used to forward notifications, then the system can operate in areas with limited network access, but the device complexity increases
Solution Approach 1:
The notification relay system is segmented into multiple independent relay devices distributed across different network zones. Each relay device is a simple, standalone unit that performs basic receive-store-forward functions. This segmentation allows the system to adapt to various network conditions by routing notifications through different segments without requiring complex coordination between relays
Solution Approach 2:
Relay devices are designed as universal nodes that can forward notifications from any user device to any account repository using standardized protocols. They perform multiple functions (receiving, storing, forwarding, error handling) within a single device architecture, reducing overall system complexity compared to having specialized devices for each function
Data Source
AI summary
Systems and methods are disclosed for security breach notification. In one implementation, an indication of a security breach is received, at a first device with respect to a user account. Based on the indication of the security breach, a processing device generates a security breach notification, the security breach notification including an instruction to initiate at an account repository one or more actions with respect to the user account. An attempt is made to transmit the security breach notification to the account repository via a first communication interface of the first device. In response to a determination that the security breach notification was not successfully transmitted to the account repository, the security breach notification is transmitted to a second device via a second communication interface of the first device.
