Dear Colleagues, Thankyou for your detailed, and prompt, helpful advice on this issue, which I much appreciate.
I see that I have overestimated my anxieties but should probably still move a little cautiously. Thus I will first suggest to my IT encryptors' taskforce, for want of a better term, that as I promise to delete any past 'sensitive files' , and in future will only consult data of this type if held in a university repository, I propose not to have encryption for the time being. Best regards, John Prof John R Helliwell DSc
