Researchers Retrieve Stored Data in Second-Hand Memory Cards

In a recent study by researchers from the University of Hertfordshire in the UK, it was established that data from the previous owner can still be retrieved from second-hand memory cards.

Using 100 second-hand SD and MicroSD cards purchased from eBay, auctions, second-hand shops and other sources over a period of 4 months, the researchers found that data in 36 had not even been deleted at all. Data from the 29 cards that had been formatted and 2 cards had their data deleted had been easily recovered. Only 25 out of 100 cards had their data erased irrevocably by a program designed to overwrite files repeatedly.

Comparitech.com’s privacy advisor Paul Bischoff reminded that simply deleting a file from the device does not actually delete the ones and zeros that make up the file.
