Code Processing Apparatus for Secure Linker Compatibility

The patent applies preliminary action by performing selective concealment on specific portions of the code (such as confidential information or trade secrets) before providing the code to other developers. The code processing apparatus identifies and conceals only the necessary portions while leaving other parts accessible, allowing the linker to process the code without requiring full decryption. This resolves the contradiction by maintaining secrecy where needed while preserving linker compatibility.

The patent applies local quality by implementing differential concealment strategies on different portions of the code. Instead of encrypting the entire code base, the system applies concealment only to specific sections that require protection (e.g., confidential algorithms, proprietary logic), while leaving other sections in plaintext. This allows the linker to process unprotected sections normally while maintaining security on sensitive portions, thus resolving the contradiction between secrecy and compatibility.

The patent applies the extraction principle by separating the concealment function from the linker itself. Instead of modifying the linker to handle encrypted code, the system extracts the concealment operation to a preprocessing step performed by the code processing apparatus. The linker receives already-concealed code and processes it using standard mechanisms, thus maintaining code secrecy without increasing linker complexity or requiring special linker development.

The patent introduces an intermediary component (the code processing apparatus) that sits between the code author and the linker. This intermediary performs the concealment operation on specific code portions before passing the code to the linker. The linker remains a standard, unmodified tool that processes the pre-processed code, thus maintaining secrecy through the intermediary while avoiding the need for a complex special linker.
