When discussing confidential information in public, you should be extra careful to avoid arousing suspicion or leaking information. Here are some things to note: 1. **Choose the right environment**: Try to choose a relatively quiet and secluded place, such as a private room or a corner away from the crowd, and avoid places where there may be bystanders. 2. **Use vague language**: Use code names, metaphors or internal terms to replace specific confidential information to reduce the risk of being understood by outsiders. 3. **Control the volume**: Keep the volume of the conversation low to avoid being overheard by others. Pay attention to the noise of the surrounding environment to prevent the information from being eavesdropped through the wall. 4. **Use technology**: When discussing sensitive topics, you can consider using encrypted communication tools instead of face-to-face communication. 5. **Trusted people**: Make sure the person you are discussing with is someone you can fully trust, and only discuss when necessary. 6. **Brief and focused**: Avoid long or detailed discussions, focus on conveying key information, and reduce potential risks. 7. **Monitor the surrounding situation**: Pay attention to the people and movements around you to prevent intentional or unintentional eavesdropping. 8. **Avoid documents with specific markings**: Try to avoid using printed confidential documents during discussions to prevent them from being accidentally read or lost. 9. **Follow-up measures**: Evaluate the communication process afterwards to ensure that there is no information leakage, and remind relevant personnel to keep confidentiality. Through these strategies, the risk of information leakage when discussing confidential information in public can be reduced to a certain extent.
