Cryptography expert Jon Callas is making his way back to Apple with hopes of boosting security of Apple’s products and keep both hackers and even the authorities from breaking in. It’s Callas’s third time back with Apple. He has since co-founded some well-known secure communications companies like Silent Circle, BlackPhone, and PGP Corp.
He rejoined the company this month. Callas’s first stint with Apple from 1995 to 1997 had him serving as Security Privateer and he helped create features such as “FileVault 2” full-disk encryption. During 2009 to 2011, he designed the encryption system for data on Macs.
