You may have heard many news stories about the legal battle between Apple and the FBI over unlocking an iPhone that belonged to the San Bernardino shooter. However, that was just one battle in a much larger fight.
Now, in an effort to make its iPhone surveillance-and-hack proof, Apple has rehired security expert and cryptographer Jon Callas, who co-founded the widely-used email encryption software PGP and the secure-messaging system Silent Circle that sells the Blackphone.
This is not Apple’s first effort over its iPhone security.
Just a few months back, the company hired Frederic Jacobs, one of the key developers of Signal — World's most secure, open source and encrypted messaging app.
Now Apple has rehired Callas, who has previously worked for Apple twice, first from 1995 to 1997 and then from 2009 to 2011.
During his second joining, Callas designed a full-disk encryption system to protect data stored on Macintosh computers.
Apple's decision to rehire Callas comes after rumors that the company is working on improving the security of its iOS devices in such a way that even Apple can't hack.
Earlier this year, Apple was engaged in a battle with the US Department of Justice (DoJ) over a court order asking the company to help the FBI unlock iPhone 5C of San Bernardino shooter Syed Farook.
Basically, the company was deliberately forced to create a special, backdoored version of its iOS, so that the FBI may be able to Brute Force the passcode on Farook's iPhone without losing the data stored in it.
Although Apple refused to do so, and now the Apple wanted to remove its own ability to break its iPhone security in future iPhone models, thereby eliminating the chances for government and intelligence agencies for demanding backdoors.
