Vanishing Message 1.0

Vanishing Message is a file message that can be sent by email attachment or file transfer. The message can be read by the recipient then vanishes without a trace. As we all know there are times when we need to send a message to someone that we want no trace of later. Vanishing Message uses a random encryption on all words, no word is ever encrypted the same. The message vanishes if exited, cannot be copied, if viewed longer than 1 minute it vanishes and you can use the same file to forward or email another person a new message. So prove it!!! Did it ever exist?
