This Email Will Self-Destruct: AT&T Seeks Patent

Demand for self-deleting messages is on the rise, as demonstrated by Snapchat's $800 million valuation and AT&T's related patent filing.

While AT&T's patent application appears to be geared to the business set, other companies are already selling similar tools for consumers. Snapchat, for example, allows users to set a photo to be viewable for up to 10 seconds, and the sender gets notified if the recipient attempts to perform a screen grab. The service, which works on iOS and Android devices, now moves more than 150 million photos in a single day, compared to the 40 million photographs Instagram sees daily, though Facebook's Snapchat clone, Poke, appears to lag behind.

Snapchat reportedly sports a predominantly teenage user base, which has drawn predictable cries that the service is merely a front for sending dirty messages, aka sexting. But Snapchat co-founder Evan Spiegel has dismissed that criticism, telling TechCrunch: "I'm not convinced that the whole sexting thing is as big as the media makes it out to be." Regardless, Snapchat is currently valued at $800 million, the Guardian reported Wednesday.

In a statement, Snapchat investor Dennis Phelps of IVP said that one of the reasons his firm decided to invest in Snapchat was because fleeting messages offer a new way of communicating. "The temporary nature of the photo or video often creates a sense of excitement and an urgency of consumption that is rare in this era of information overload," he said.

Competing services, such as Wickr, allow any type of multimedia message to be encrypted and set to self-destruct, as well as to communicate anonymously -- useful for journalists working with anonymous sources.

But Derek Schueren, general manager of information access and governance at Recommind, told Byte that such services might expose businesses to legal liabilities, if they didn't retain information required for responding to lawsuits, patent requests or per regulatory requirements. "You have an obligation [to retain data] if there's a possibility of litigation," he said, with that obligation extending not just to email but other business communications.

Furthermore, message-deletion services may promise more security than they actually provide. Richard Hickman of Decipher Forensics reported in April that by using AccessData's Forensic Toolkit on a Samsung Galaxy S3 -- which runs Android -- with Snapchat installed, he'd been able to restore supposedly deleted "snaps." All that was required was removing the ".nomedia" extension appended to the end of an images marked for deletion.

As I was reading this article, I wondering what these companies would do for reporting or legal purposes if the emails self-destructed. Then I saw Schueren's comment that businesses could be exposed to legal liabilities. I'd have to agree with this, but I would further note that this could create some transparency issues for both businesses and governmental entities. It would be a lot harder to maintain an open and transparent government if this ability allowed government employees to send self-destructing emails to hide certain details from the public.

Bigstring Corp already has a patent in 2005 for the same process

re: This Email Will Self-Destruct: AT&T Seeks Patent

I've created a simple tool that allows encrypted email messages, text messages, instant messages, or anything else to be sent as a link to a temporary self destruct container powered by a secure connection to a SQL database.

It even has a lifespan. I launched it a few months ago, then ATT comes out looking to patent more ideas. Interesting timing. free for all to use. Market value of the company is unknown. The tool has other features, encrypts text and lets you bury it in an obfuscated URL or inside the alpha channel of an image.

Since my tool uses open source technologies, and directly it competes with the idea of a self destruct email without actually being a self destruct email. The problem with a self destruct email is that it can never actually exist (emails can be read by every machine they pass through, typically 3 to 5 minimum in even the shortest routing). is free, advertising based.
