Gmail Confidential Mode is Neither Secure Nor Private (protonmail.com) 67

Posted by msmash from the closer-look dept.
Even though Google launched confidential mode over a year ago, people are still confused about what it does. Is it actually secure or private? Is it encrypted? From a report: When you turn it on, does it prevent Google from reading your messages? The answer to these questions is 'no.' In fact, the decision to call it "confidential" suggests a level of security and privacy that doesn't exist in Gmail confidential mode. Gmail's confidential mode does not mean your messages are end-to-end encrypted. Google can still read them. Expiring messages aren't erased for good, and the recipient can always take a screenshot of your message.

Gmail's confidential mode does not make emails private because Google can always read them. When you send an email with confidential mode turned on, Google keeps the email contents on its servers. Other Gmail users can read the email in their inbox, but outside users only receive an email notifying them that a sender "has sent you an email via Gmail confidential mode" along with a link to a page on google.com.

    A lot of companies use something like SendInc. It's almost identical to Gmail Confidential. It allows you to address a message, attach files, and then send it to another user. The recipient can open the SendInc message, download attachments, and print stuff. When the message expires, the recipient can no longer access it to download attachments or print the message.

    It makes it handy for sending things like patient xrays to a new dental office for example. It's an easy way to transfer records without us

      Why use insecure e-mail when you can use secure email instead? My e-mail is secure ... why isn't yours? Oh, because you do not have e-mail ... you have someone else's computer system calling itself e-mail over which you can exercise no control. Got it. I understand perfectly.

      You think all e-mail is insecure because YOU have chosen INSECURE E-MAIL for yourself and assume that everyone else did as well.

      The pox on you, moron.

    • except it prevents you from downloading/accessing attachments or printing the message.

      This is completely and utterly wrong. If a browser can display information, that means it is downloaded to recipient's computer. Whether the user can use data in a way that was not intended to is depending on his/her personal abilities.

      That is also why Anonymous Coward feature in /. is wrong and harmful. No computer professional or a geek or anybody with any claim of technical competency can write a message that wrong this recklessly with their name attached.

  • Gee, if you have to ask that question you must have been living in a cave for the past few years. Do you really think that any privacy setting that google (or Facebook, for that matter) provides to its users will affect the ability of google (or Facebook) to slurp up all your data? Really?

      Well, in mobile instant messaging platforms (think Whatsapp/Telegram), the client installed in your device *does* encrypt messages to the recipient device's key — Whatsapp is owned by Facebook. So, yes, it *could* mean it is confidential if a similar arrangement were to be used. Of course, it is not the case.

      Some people do not understand how the technology works, hence they may believe such a thing. Lets just say this is not going to happen. The only thing that Google really makes money on is targeted ads. These require data and there is no way to prevent google from seeing things that are on their servers.

      It breaks interoperability.
      With confidential mode on, gmail messages the non-gmail-users receive will just be a link to an autogenerated gmail webpage. In order to read the message, you will have to follow the link.
      So, goodbye to offline mail reading.
      Goodbye to mailing lists (and, of course, their archives).
      Goodbye to me being able to archive my mails however I see fit.
      I hope they backpedal. They might achieve killing email as a multitenant, interoperable communications medium.

      It's the equivalent of what other companies refer to as "secure email". It guarantees that direct access to the content is done over encrypted communication, and provide some level of tracking. It also is more difficult for a third party to read the content in transit than traditional email, while being easier to use than S/MIME. Any other inferred security or privacy doesn't exist.

      - The email self destructs, a bit like Snapchat.
      - You can require the recipient to enter a code that is sent via SMS.
      - Copy, Forward, etc... are disabled.

      It is not at all the same purpose as end-to-end encryption ala ProtonMain. It won't do much against for big, distant threats (state actors, police, hackers, ...) but it can be effective against small, close threats (significant others, coworkers, friends, family, ...).
