Using codes or short IDs in file names for confidential documents involves structured identifiers instead of descriptive names. Codes are typically longer, complex strings potentially incorporating encryption or specific meaning, while short IDs are brief, often sequential, alphanumeric references like project numbers. Both aim to obscure document content from unauthorized viewers at the file name level, differing from clear naming by hiding purpose. The key choice balances obscurity against practical usability.

In practice, legal firms commonly assign unique case codes to client documents, ensuring confidential matters remain undisclosed on shared systems. Research labs might use short, project-specific IDs on patent-related files, hiding specific research details while allowing authorized internal identification. Secure document management platforms often facilitate both approaches.

Opting for codes or IDs enhances confidentiality by obfuscating sensitive content, reducing risk during inadvertent exposure or unauthorized access. However, it complicates navigation and retrieval for legitimate users and risks misclassification without robust tracking. Overly complex codes can lead to human error, potentially causing data loss. Future systems increasingly integrate contextual security (like access controls and encryption) alongside simpler names, as poor naming practices themselves can pose significant security risks despite good intentions.
