Resetting Android is not Completely Delete the Data

A study showed that the application was not sufficient data eraser to remove personal data, including "selfie pictures embarrassing".

A new study from security software vendor Avast questioned the effectiveness of the reset option. Avast is known for its security software on Windows, Mac and Android, the Android phone to buy 20 of the former 80 thousand smart phones being sold on eBay.

From the mobile phone, the employee Avast managed to find more than 40 thousand photos, including 250 selfie photos of naked men together with electronic mail and SMS 750, 250 contacts, four previous phone user identity, and the loan application, as quoted from Cnet.com.

The Director of Avast Mobile Devices Jude McColgan said that people usually do not take into account the impact of storing personal data on their phones.

"Users think they've done a total clean-up and restoration of data factory but in fact it is just cleaning your cell phone in any application level," he said.

"We have a very unique relationship with the phones that we've never experienced with any other technology. In other words, we identify the phone as the entrance to our virtual home," said Bronson James, a lawyer who took care of one of the cases related to mobile phones in Supreme Court.

Avast does not require a lot of effort to recover the data from which they are derived cell phone, said McColgan.
His team uses digital foreksik application available to the public such as FTK Imager is a drive-imaging program.

"Although at first glance it appears that mobile content has been completely removed, but we were quickly able to take back a lot of personal data. In most cases, we have to perform low-level analysis that helps us restore SMS and messages conversations," said researcher Avast, Jaromir Horejsi and David Fiser.

Avast in their report said that Android security apps that they make have the ability to remove personal data better than the default reset option on the phone.

"There is a challenge to make people more aware about the security of the computer and so if there is in your pocket," he said.
