Storage Medium Controller Pin Position Conversion for Copy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic storage media lack effective copyright protection against illegal copying and hacking, as current security measures are insufficient to prevent unauthorized access and data theft.
Innovation Solution
A data storage medium incorporating One-Time Programmable (OTP) memory and a security controller that authenticates output apparatuses by comparing unique numbers, converting pin positions and data storage locations using key data, thereby preventing unauthorized access and ensuring secure data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electronic storage media are used to store media content, then data accessibility is maintained, but copyright protection and security against illegal copying are insufficient
Solution Approach 1:
The patent applies preliminary action by pre-storing unique identification numbers in the OTP memory during manufacturing and pre-configuring the security controller with authentication logic. This allows the storage medium to perform security functions automatically upon connection without requiring additional security hardware or complex user setup, thus improving copyright protection while minimizing device complexity
Solution Approach 2:
The patent introduces an intermediary authentication mechanism where the controller acts as a mediator between the storage medium and the output apparatus. It compares unique numbers from the output apparatus with stored values and controls data transmission accordingly. This intermediary layer provides robust copyright protection without requiring the output apparatus itself to be complex, as the security logic resides in the storage medium's controller
2Reliability
If authentication mechanisms are added to storage media, then security against unauthorized access is improved, but device complexity and hardware additions increase
Solution Approach 1:
The controller in the patent performs multiple functions: it manages normal data read/write operations, performs authentication by comparing unique numbers, and controls security functions. By making the controller universal and multi-functional, the patent avoids adding separate dedicated security hardware components, thus improving security function while minimizing hardware additions
Solution Approach 2:
The storage medium is self-sufficient in performing security functions through its built-in OTP memory and controller that can autonomously authenticate output apparatuses and control data transmission. The system does not require external security hardware or complex additional components, as the storage medium itself provides all necessary security services, minimizing hardware additions while maintaining robust security
3Reliability
If OTP memory is used to store unique numbers, then unauthorized copying is prevented, but manufacturing complexity increases
Solution Approach 1:
The OTP memory is pre-programmed with unique identification numbers during the manufacturing process itself, rather than requiring post-manufacturing configuration. This preliminary action during manufacturing simplifies the overall process by integrating security configuration into the standard production line, preventing unauthorized copying while maintaining ease of manufacture
Solution Approach 2:
The patent uses OTP memory which is a cost-effective, one-time programmable storage solution. Once programmed with unique numbers during manufacturing, it provides permanent copy protection. The low cost and simplicity of OTP memory technology make it economically viable to integrate into storage media without significantly increasing manufacturing complexity, achieving reliable copy protection at minimal added cost
