Yahoo is expanding its efforts to protect its users’ online activities from prying eyes by encrypting all the communications and other information flowing into the Internet company’s data centers around the world.
The commitment announced Monday by Yahoo Inc. CEO Marissa Mayer follows a recent Washington Post report that the National Security Agency has been hacking into the communications lines of the data centers run by Yahoo and Google Inc. to intercept information about what people do and say online.
Yahoo had promised to encrypt its email service by early January. Now, the Sunnyvale, Calif., company plans to have all data encrypted by the end of March to make it more difficult for unauthorized parties to decipher the information.
Google began to encrypt its Gmail service in 2010 and has since introduced the security measure on many other services. The Mountain View, Calif., company has promised to encrypt the links to its data centers, too. A Google engineer said that task was done this month, but the company hasn’t yet confirmed all the work is done.
