Following the example of Google who added encryption to their email services a few months ago, Yahoo have now confirmed an increase to their user security that will become available to 600 million users by 2015. This increased security will arrive in the form of enterprise grade, end to end encryption capabilities that will help to protect information stored within a user’s email.
The new feature was announced at a recent security conference, detailing the type of encryption to be used and how it would be activated. It was highlighted that the encryption services would not activate automatically, but that the user must in fact operate it manually. The new service is expected to be a PGP variant; where encryption keys are stored on the user device opposed to being stored centrally third party.
PGP may protect privacy on the user’s device however still remains to provide zero protection to the user whilst the email is on it’s journey due to the inability to encrypt the identity of a recipient or the subject line of the email. Unfortunately, PGP encryption still does not provide full protection to a user’s email box due to information being easily collected through browser history, providing the intruder with all the information they need to access your accounts. All in all, the only form of protection via your browser is by using private and incognito windows, although even these aren’t always as secure as a user would desire.
