According to Sheryl Willert in "Practical Considerations To Protect Trade Secrets," several basic requirements for protecting trade secrets can be gleaned from the cases discussed in her article:
- Reasonable precautions against industrial espionage
- Marking plans and documents 'confidential'
- Use of 'confidentiality' legends, warnings and agreements
- Restricting visitors and similar types of plant security
- Locking up or otherwise securing sensitive information
- Taking technical precautions, such as dividing the system into steps handled by different individuals or departments
- Copy protection and embedded codes to trace copies
- Employee exit interviews.
