趣聽精彩世界：手機"恢復出廠設置"的隱患

BBC新聞：捷克一家安全公司從被“恢復出廠設置”的舊手機中提取出了數(shù)千張照片，包括許多躶體自拍照。大多數(shù)智能手機都有“恢復出廠設置”的功能，可以對手機初始化。但這家叫做Avast的公司發(fā)現(xiàn)，一些老款智能手機只刪除了數(shù)據(jù)的索引而并非數(shù)據(jù)本身。這意味著手機中存儲的照片，電子郵件和短信可以相對比較容易的恢復。

恢復出廠設置的隱患

BBC News: Thousands of pictures including "naked selfies" have been extracted from factory-wiped phones by a Czech Republic-based security firm.

The firm, called Avast, used publicly available forensic security tools to extract the images from second-hand phones bought on eBay.

Other data extracted included emails, text messages and Google searches. Experts have warned that the only way to completely delete data is to "destroy your phone".
