Dead Man’s Switch. Something something Notary Public
Whatever Snowden did
And you’ll need to publicly advertise that you are using one for it to be effective.
Not necessarily. The only people who would need to know are the people who are already researching you to have you killed for a potential leak, and they would operate under the assumption of a DMS in place already.
Also, the payload needs to be worse than what you are already disclosing…
Not necessarily. They just need to want to prevent it from being disclosed more than they want to kill you.
Worth noting that this is something that can change over time. For example, if Snowden had done such a thing, it would be essentially useless now, since the known and accepted activities of the US government are now worse than what Snowden revealed.
