YOUR PHOTOS ON SMARTPHONES CAN BE FOUND EVEN AFTER DELETING. Hundreds of naked selfies and intimate pictures were found on a batch of 20 Android phones bought through eBay and tested by researchers. A factory reset function appears on the smartphones, but standard forensic security tools can retrieve deleted information from older devices. The researchers said they found more than 40,000 photos, including 750 photos of women in various stages of undress and 250 photos of male anatomy. Details of the persons residence could also be traced using EXIF data embedded in the image file. Four of the phones tested included the previous owners identity in the file data. One Reddit user said he had been contacted by someone who bought his phone, saying they had extracted embarrassing images from the device. The factory reset function on older Android devices wipes the index that points to the locations where data is written, but forensic tools can still directly access storage areas. Google has said that more recent versions of Android are harder to crack. That is because phones running Android 3.0 onwards offer a setting to encrypt the phone using a cryptographic key generated from a users passcode. A reset will then delete the key, rendering the data unreadable. Newer Apple iPhones and iPads encrypt data by default using a software key which renders all data unreadable after a reset.
