Secure Trace Management in Mail Processing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Software tracing in mail processing devices like mailing systems or inserters faces challenges due to high trace message volumes, limited storage capacity, and the inability to write to non-volatile memory, along with difficulties in uploading traces to remote servers due to connectivity issues and security risks in local network transfers.
Innovation Solution
A method involving a storage apparatus connected to the mail processing device for activating and storing traces, using a circular buffer for temporary storage, continuous low-priority transfer of selected traces, and secure encryption to manage and transfer traces, with activation and deactivation controlled by a traces key or barcode, ensuring only authorized personnel can initiate trace generation and transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If traces are continuously stored in non-volatile memory, then trace data is preserved permanently, but writing to non-volatile memory is too time-consuming and disrupts real-time operation
Solution Approach 1:
The patent divides the storage system into two segments: volatile memory (RAM) for real-time trace buffering and non-volatile memory for permanent storage. The circular buffer in volatile memory handles high-speed trace capture without blocking real-time operations, while periodic transfers to non-volatile memory preserve traces permanently without disrupting device operation.
Solution Approach 2:
The patent introduces a trace management module as an intermediary between the trace generation sources and storage systems. This module buffers traces in volatile memory, manages transfer to non-volatile memory asynchronously, and handles upload to remote servers, thereby isolating the time-consuming storage operations from real-time trace capture.
2Quantity of substance
If traces are uploaded to a remote data server, then trace data can be stored externally, but a permanent connection is required which is difficult and expensive to support
Solution Approach 1:
The patent implements dynamic trace upload capability where the system can adapt between local storage mode and remote upload mode based on availability of network connection and user needs. The trace management module can buffer traces locally and perform uploads opportunistically when connection is available, or maintain local storage indefinitely, making the connection requirement flexible rather than permanent.
Solution Approach 2:
The system performs trace uploads periodically or opportunistically rather than continuously. The trace management module can accumulate traces locally and transfer them to remote servers at scheduled intervals or when network conditions permit, eliminating the need for permanent connections while maintaining external storage capability.
3Ease of operation
If traces are transferred on the customer local network, then trace data can be accessed locally, but network availability is not guaranteed and data security is at risk
Solution Approach 1:
The patent implements authenticated trace transfer where the mail processing device itself performs authentication of the storage apparatus before allowing trace access. The device manages its own trace data security through built-in authentication mechanisms, eliminating reliance on external network security infrastructure while maintaining controlled accessibility.
Solution Approach 2:
The system prepares trace data for secure transfer by implementing authentication and encryption protocols before actual data transfer occurs. The trace management module verifies the legitimacy of access requests in advance and establishes secure communication channels beforehand, preventing unauthorized access and ensuring reliability even when network conditions are variable.
4Loss of information
If all traces are generated and stored, then complete diagnostic information is available, but storage capacity is exceeded and performance is impacted
Solution Approach 1:
The patent implements selective trace generation and filtering where different trace levels and categories can be enabled based on specific diagnostic needs. The system can focus on capturing only relevant traces for particular malfunction types or operational phases, storing detailed information selectively rather than uniformly, thereby maintaining diagnostic completeness for critical issues while reducing overall storage consumption.
