Apple has hired key person behind an encrypted messaging app called Signal. Last year, Frederic Jacobs said they will bring strong cryptography techniques to iPhone users. According to Jacobs, he will be the company as an intern. Signal is the best encrypted messaging app used by the United States whistleblower Edward Snowden. With this hiring, it hints Apple is serious making their services more secure in the future. Maybe the internship program will be his job interview at Apple.
