TealAndTurquoise, could you have a look and see how many people's passports you have copies of still lurking around on your computer, and on any web-based mail services you may use?
Eg I use gmail but through my Mac's mail app, so I end up with a copy of everything on my machine and another copy lurking on gmail's servers which I rarely log into separately.
If you have any passport images AT ALL, you are now responsible under data protection legislation for their safe-keeping.
In fact if you do have any, you are probably already in breach of data protection legislation, which states that you must delete personal data when you no longer have a business need for it. Given you pass the data onto recruitment, you no longer need it yourself and must delete all copies in your possession.
