Cryptic

As an NHS employee I have a duty of confidentiality. We have to use encrypted memory sticks to transfer files from computer to computer or to work on at home even though there is no patient identifiable information in the files.
Causes us a lot of inconvenience in the lab as the IT department won't allow some of our computers on the network, but we appreciate the reasons why.
Shame they are not so strict with dictaphones and case-notes!
The wear and tear on my stick wasn't apparent till I looked at this image in colour.
