I’ll have missed whether you intended to add these words to the date and time stamps in the file names, or whether you intended to replace them. The former drastically increases permutations and thus lowers the risk at generating collisions, especially at subsecond intervals.
Recently I implemented an idea for this I first saw with Keybase: to generate a security key based on 9 or 10 dreary dull words. Each subsequent word increases the permutation power exponentially, meaning the initial list doesn’t even have to be all that long.
How fast do camera shutters shut? How many subzero pictures do they take? Does it differ from one model to the next? And: is your storage system capable of keeping up when you have it rename every photo it receive?
Ah yes, nothing screams “Nobel Peace Price” quite like spearheading war upon war, funneling tax-payers’ money into the war industry. So. Much. Winning.
