Personal info left on computers and phones, says survey
A new survey shows people aren't deleting files from their old mobile phones and computers before they sell them.
That means new owners could steal information such as dates of birth, credit card numbers and passwords - and use them to pretend to be the old owner.
The survey by the Information Commissioner's Office (ICO) showed one in 10 second-hand hard drives weren't properly wiped.
The ICO bought second-hand devices including 200 hard disks, 20 memory sticks and 10 mobiles.
Nearly half still had information in the memory that belonged to the original owner.
At least two of the drives had enough information to enable the new owner to pretend to be someone else.
Christopher Graham, who was in charge of the survey, said: "Many people will presume that pressing the delete button on a computer file means that it is gone forever. However this information can easily be recovered."
