Access System Identification Code Verification for Electronic Product Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During electronic product manufacturing, initial setting values are written by factories, but designers cannot monitor or control the write operations, leading to potential leaks of commercial secrets and unmanaged successful or unsuccessful executions.
Innovation Solution
An access system comprising a storage medium with an identification code and a host processor that executes a mass-production application program, where the processor determines whether the identification code matches a key code to write data to electronic products, with counter values managing the number of write operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If factory executes write operation to write initial setting values into electronic product, then electronic product can be manufactured and initialized, but designers cannot monitor or control the write operations leading to potential leaks of commercial secrets
Solution Approach 1:
A storage medium with identification code serves as an intermediary between the factory execution environment and the design security requirements. The storage medium must be physically present and verified through identification code matching before write operations can proceed, creating a controlled interface that maintains both manufacturing capability and security.
Solution Approach 2:
The identification code verification is performed preliminarily before any write operation occurs. The system checks whether the storage medium's identification code matches the expected key code before allowing the mass-production application program to execute, preventing unauthorized operations from the outset.
2Productivity
If factory writes initial setting values into electronic product without monitoring, then manufacturing process is simple and fast, but the number of successful and unsuccessful executions of write operation cannot be obtained
Solution Approach 1:
The system implements feedback by storing execution status information in the storage medium. After write operations are completed (whether successfully or unsuccessfully), the results are recorded and can be retrieved later, providing information feedback without interrupting the manufacturing flow during operation.
3Reliability
If identification code verification is implemented before write operation, then commercial secrets are protected and write operations are controlled, but system complexity increases with additional verification steps
Solution Approach 1:
The storage medium itself carries the identification code and participates actively in the verification process. The storage medium provides its own identification information that the host system verifies, making the security mechanism self-contained rather than requiring external verification infrastructure.

AI summary
An access system including a storage medium and a host is disclosed. The storage medium includes an identification code. The host includes a processor, at least one connection port and an identification port. The processor executes a mass-production application program. The connection port is coupled to at least one electronic product. The identification port is coupled to the storage medium. When the mass-production application program is executed, the processor determines whether the identification code matches a key code. When the identification code matches the key code, the processor writes mass-production data to the electronic product.
