Japan's Philanderers Stay Faithful to Their 'Infidelity Phones' - WSJ.com

"Women may want to check my phone for strange emails or calls when I'm not around. With Fujitsu's 'privacy mode,' they can't see that information at all," he said in an email. "The key is to give off the impression that you're not locking your phone at all." Fujitsu's "privacy mode" is a layer of nearly invisible security that hides missed calls, emails and text messages from contacts designated as private.
