Using a tool like steghide you can hide the file in a picture or sound file, so people won't even notice that there are secret data available. To add extra security, first encrypt your file as proposed by several others, and then use steghide to hide the encrypted file.

Example:

Code:
steghide embed -cf picture.jpg -ef encrypted_file -sf new_picture.jpg
The file new_picture.jpg will look identical to the file picture.jpg, but the secret information is hidden in it. To retrieve your original secret data:

Code:
steghide extract -sf new_picture.jpg
steghide is in ports:

/usr/ports/security/steghide
