If you’re looking for a more secure way to create (and view) instant messages, developer BigString has a solution for you. The company has developed a new IM application that can leverage existing IM clients—such as AOL’s AIM, Yahoo’s Messenger, MSN’s Messenger, and Google’s Gtalk—to send IM messages that vanish after a set period of time.

According to BigString, the patent-pending IM technology lets users send instant messages that selfdestruct after they’re read. Screenshot utilities can’t capture, log, or otherwise copy them. The service doesn’t leave copies of messages on any server or client machine, and you can specify self-destruct intervals to be anywhere from a few minutes to a few hours.

In its product announcement, BigString touted its product’s ability to work with existing IM clients. “Our new web-based IM makes it very easy for IM users to have private conversations with current IM buddy lists without having to switch to a new service,” stated Darin Myman, president and CEO of BigString. “Our strategy to quickly grow our IM user base revolves around creating unique applications that leverage the tens of millions of existing IM users.”
