Re: entropy of data....?

: Hasn't someone come up with a name for this like "Entropy of the data is 30 : days" or... "the half-life of the data is 15 days". This is a critical : value when looking at it from a military point of view. If you can't decode : enemy plan for attack before a certain date/time then the info is : useless.... That betrays a bit of ignorance about the meaning of 'half-life'. I think the word you're looking for is 'lifetime'. G
