In this Trust (York) all usb ports on networked pc's will read from standard sticks but only write to Trust issued encrypted sticks with an additional secure logon. This is to prevent unauthorised copying of patient data onto a stick which could then be 'lost' and found /read by anyone. It has caused a few problems but nothing which could not be resolved fairly quickly. In this case could the images be copied directly to the pc, usb-usb? We've a growing issue over the security of patient data held in equipment - Does anyone have a policy/procedure for dealing with this?
