Comcast has answered Google's call to email providers to use encryption to enhance users' security. On Tuesday, Google revealed its email traffic with other providers that remains encrypted and found than less than 1% of messages sent from Gmail to Comcast.net address remained encrypted. Google has been encrypting its Gmail messages since 2010, but it only remains that way if it's encrypted on both the send and receipt ends. Now, Comcast said it would begin encrypting its users' emails for security. Encryption means the data within the message is scrambled, making it more difficult for government surveillance or snoops to access the information.
