Yahoo has added more layers of security in its effort to shield people's online lives from government spying and other snooping.

The measures include the completion of a system that encrypts all information being transmitted from one Yahoo data center to another, said ABC News.The technology is designed to make the emails and other digital information flowing through data centers indecipherable to outsiders.

Search requests made from Yahoo's home page are also now automatically encrypted, and the company is promising to make it more difficult for unauthorized intruders to hack into other services, including video chats, within the next few months, said ABC News.
