Given how vague the question is, I can only give you vague answers:

1. Don't let them near your data. If your files never leave your computer, no one can view them (unless they have access to your computer).
2. Put your data under a lock and only give the keys to people you trust. The keys can be either something they know (usually username and password), something they own (hardware key, cell phone to which you send an SMS, fingerprint) or a combination of both.
3. Encrypt your data.
