This article is a rather interesting look at what sensitive data tech-heads like myself might be inadvertently giving away, whenever we grow tired of our current smartphone and eBay it for the Next Big Thing. Evidently, the reset feature available on most smartphones doesn’t always do the trick as effectively as one would think:
A company, Trust Digital of McLean, Va., bought 10 different phones on eBay this summer to test phone-security tools it sells for businesses. The phones all were fairly sophisticated models capable of working with corporate e-mail systems.
Curious software experts at Trust Digital resurrected information on nearly all the used phones, including the racy exchanges between guarded lovers.
The other phones contained:
-One company’s plans to win a multimillion-dollar federal transportation contract.
-E-mails about another firm’s $50,000 payment for a software license.
-Bank accounts and passwords.
-Details of prescriptions and receipts for one worker’s utility payments.
The recovered information was equal to 27,000 pages – a stack of printouts 8 feet high.
“We found just a mountain of personal and corporate data,” said Nick Magliato, Trust Digital’s chief executive.
Sadly, this article is a thinky-veiled informercial for an upcoming product that TrustDigital intends to sell to capitalize on the FUD factor of identify theft and smartphones. But in spite of this, the article really sheds light on the fact that once again, “deleting” data on an electronic device doesn’t guarantee that the information is truly gone.
Not too long ago, this issue wasn’t really a huge problem. Cell phones were much simpler just a couple years ago, not as readily capable of exchanging e-mails, IM-style text messages with multimedia, and even Word and MS Office documents, like they can now. And even the few models that did have a high level of sophitiscation were at the time built with DRAM, a type of memory that required constant power to retain data, and which really could be thoroughly wiped by simply disconnecting the battery.
But, batteries run down and inadvertent phone amnesia was common, frustrating users who were unfortunate enough to not recharge their smart devices in time. So, around 2003-2004, hardware makers made the switch to flash memory, which required no power to retain data, but were also much harder to permanently wipe.
For those Treo users who are interested, the article makes note of the “zero out reset” function, which does actively clear data from the handheld. Info on how to perform this type of reset can be found here. Just beware that as the page indicates, you have be one heck of a contortionist to perform this function by yourself, and a willing “dexterous friend” is often necessary.
