Okay, I'm not advocating (or opposing) this concept. It just seemed to me that since we are talking TOR-related features, we should pay attention to what TOR currently claims to provide. I think a few months ago, I mentioned the idea (which I assume somebody else thought of first, probably years ago) of splitting a file into two (or more?) pieces, stored in two (or more?) separate systems), which when XOR'd together, provide the (forbidden, banned, 'reallybad!!!' 'highly-illegal') product file. Neither file, alone, would be 'forbidden'. The purpose of this is not 'secrecy' of course, but merely deniability. Without the other file(s), the one file _I_ possess will be indistinguishable from a random number. In fact, it could be a random number, which when XOR'd with a forbidden text, becomes what amounts to another random number, and somebody else's system will hold the other 'random number' . Think Vernam cipher, otherwise known as a "one-time pad". https://en.wikipedia.org/wiki/One-time_pad

One application of using this XOR principle is to avoid the problem of a anonymization output node (TOR or otherwise) containing openly suspicious or incriminating information. If all data through the network splits, before it exits, converted to two (or more???) seemingly-random data steams, outputted by two (or more???) distinct nodes, it can be recombined to regenerate the desired source data. An individual node's output is simply random data. Jim Bell
