I'm so bored of hearing the accusations of PR stunts.

They crop up in every submission detailing an action taken by Google with regards to the Snowden/Prism/NSA revelations. Is it so ridiculous that a large corporation should seek to ameliorate its image in the eyes of users and shareholders?

PR has become such a dirty word.

Of course it would be best if all these actions were taken earlier, purely as the result of a strongly held principle. However, when presented with the realities of public businesses operating on a global scale - I am glad that such steps as those detailed above are taken: at whatever stage, and for whatever reason.

The tinfoil hat brigade needs to, as the old saying goes, "stop seeing reds under the beds" and occasionally ... just occasionally ... take the facts presented to them.

In times when misinformation and confusion is so wont to proliferate, attempting to discern true motive is almost ridiculous - condemnation on the basis of any such discernment doubly so.

When Google does something that makes it impossible for them to hand over certain types of data to the NSA, either by not collecting it, or making it so that only the user is able to decrypt it, wake me up. Until then, it's a PR stunt.

I am not disputing the fact that a major motivation for their actions is PR. I am suggesting that action as a result of PR pressure is still action - vastly preferable to meek acceptance of the status quo.

That being so - dismissing something as "just PR" misrepresents the actual benefits something like this may confer.

IMAP/POP3 has always been a gmail option, which allows local PGP use. Chrome sync allows you to set your own encryption passphrase (provided you trust the binary doing the encrypting...). You've been able to share encrypted files on google docs/drive since they added arbitrary file storage. Etc.

Chrome sync is probably the strongest example that I can think of fitting your criteria, since it's built into the product itself, but a lot of this just comes with the territory of web-based apps.

They haven't done anything there though... They've just provided a standard IMAP service, and a standard file syncing service...

When they provide an option in GMail for people to upload their public PGP keys, and then start encrypting email on the way in, and don't store any non-encrypted versions of those emails, and build PGP support into Chromium for accessing those emails. Then they will have done something worth noticing.

How would spam filtering or searching work in such a service?

[mike-cardwell]

Spam filtering:

  Step 1. Spam filter
  Step 2. Encrypt

Searching:

Client side tool which builds a local index as messages are decrypted to be read for the first time. The index is it's self encrypted and incrementally synced between clients.

That took me less than 5 seconds to think up. Google can spend time and money thinking up better solutions if they want to actually do something.

If there's any sort of processing on incoming data, then there's going to be a lot of unencrypted copies floating around in various caches and intermediate staging systems. A secure system requires encrypting the data right off the wire, before it's stored anywhere.

Search indexes are very large -- you don't want to double or triple the amount of storage your email client uses. Also, being able to search only mail that you've downloaded and decrypted is a terrible user experience. I'd estimate over 60% of the mail to my personal inbox is from some automated system, rather than directly from a human, and I typically don't look at them unless a search hits them.

It takes 5 seconds to think of solutions with terrible security and usability characteristics. Thinking of a system that will be a measurable improvement in security and will actually be used by people is much more difficult.
