Clouds of suspicion

Hacking of celebrities' accounts has brought home the risks of letting others store your information, Cao Yin and Gao Yuan report.

Following the leaks of nude photos of celebrities after their iCloud accounts were hacked, Zhou Wei is reluctant to use Apple's cloud-based storage service.

"I prefer to store all my information on a mobile hard disk drive rather than use iCloud, although the latter is more advanced and convenient," said the 26-year-old, who works for a Beijing self-media company.
