First time accepted submitter el33thack3r writes "We've all wanted a trustworthy record of an online factoid, whether it's your official employment status, a tweet someone made or the hash of an open-source distribution to protect it from tampering. A group of Cornell researchers have just unveiled a service called Virtual Notary that can serve as a witness to online factoids. The service is useful for inventors who want to timestamp an invention disclosure, for people who are seeking an officially random number selected for a raffle or crypto protocol, for web services that want a record of a user's email address, and for many other use cases. The service is free and the researchers are seeking community input on other online factoids of interest. What would you like notarized online?" The concept is interesting, but some of the items they've chosen as examples seem well documented elsewhere, such as historical exchange rates and stock prices.
