Presumably after considering the consequences of doing so, Google has become a sort of unusual executor of the digital estates of users who opt in to their ‘Inactive Account Manager’ feature.
They are given the option to set how long a ‘timeout period’ must pass before the system kicks in.
They are then allowed to automatically notify and potentially share data with up to 10 “trusted friends or family members”.
They can then add an autoresponder message, either for anyone who emails them or just for contacts.
Finally, they can set up a system to delete their account.
In a way, this looks a lot like a Dead man’s switch.
This system relies upon the autoresponder feature.
If you have data that you wish to make publicly available only after your death, encrypt it with a secure-yet-commonly-used algorithm like AES.
Put the key in the body of your Google post-mortem autoresponse email.
In all likelihood, the key will circulate and people will be able to decrypt the files which you wish for them to decrypt.
I am sure Google thought this through, but it seems to me that this system might encourage suicides. There can be a certain attraction in going out by means of a dramatic gesture, and this system makes it a lot easier.
