Maybe use cloud computing. It is designed to not be decoded.
But I’m not a geek, but hubby would know more.
"Cloud computing" is a newly invented name for an old method where you store all your data on someone else's servers. This is the worst possible solution for anyone who values privacy. Also, those servers (there are just a few) can be ordered offline at any time, and then you have nothing.
For example, imagine that you use Google Groups for general discussion, Google Mail for direct communication and Google Documents for specific papers. All your data is on Google's servers, you have no locally saved copies (usually.) Now Google is offline, or your account is disabled (all of that happened several times already.) You are in trouble, isolated from your contacts and robbed of all your documents and messages.
An opposite example is FreeNet. This is an experimental network that is designed for storage of documents on multiple computers (like p2p.) No single computer holds everything, and nobody knows where the data is actually stored - the network is designed to ferret the data out, but it won't tell you where it found it. So an attacker has no easy way to disrupt the network.
“Cloud computing” is not a solution to your problem, it is the problem (you lose the privacy and possibly access, instead of gaining them) and it’s expensive proposition, to boot, to store / backup your data somewhere else.
Cloud is a “back to the future” marketing, not technological concept.
You can encode / decode email and other data, for storage or transport, with private or public encryption methods, and/or split data store / transfer on multiple computers through various P2P (legal uses) algorithms.
Potentially cloud computing. Just don’t use Google!
good idea... Also - for safety freeper groups should be grouped by sign-up year - very few trolls in the early years... or older members can be the inner ring group... we connect to the next level down...
