In this and two following articles I'd like to take a look at three different areas of personal data storage, how I see a majority of people handling these three issues and what my personal theoretical approaches regarding them is. This is going to be purely about data storage and security, not transport security, which is another topic on its own.

The questions mainly are:

  • Where am I supposed to store my private data?
  • Is my data secure?
  • Who can access my data?
  • Is security based on trust or actual scientific security (encryption)?

First of all, the three distinctions of data storage I'd like to make, and also how I'm splitting the articles, are the following:

  • Email storage
  • Preference storage (application preferences, browser syncing, phone syncing etc.)
  • Personal data storage (photos, videos, documents, contacts, calendar, etc.)

Let's start with email storage. Where are your emails stored? The vast majority of Internet users have an email account with one of the big free email providers or they might have an account that is provided by their Internet Service Provider (ISP). Maybe you even use some shared web hosting somewhere which comes with shared email servers. Whichever of these is the case: your emails are effectively stored with a third party, an ISP that is not you.

Let me ask you this: where is your mail stored? And by mail I actually refer to physical mail: letters. Where are they received? Surely you have a mailbox at your home, or you might have a post-office (PO) box. Most likely you'll be receiving your mail at your mailbox in front of your house and then store it safely inside your home. Would you want your letters to be sent to a third-party that is sending you a copy but also storing all your letters within their own house? Probably not.

I believe we have a major misunderstanding how we are treating Email currently. We are giving away our email data to big companies that make a living with it (among with other services). Always keep in mind that you're most likely not the customer when using a free service, you might be the actual product. If events in the last years regarding the NSA and Edward Snowden have shown us anything, it's that our data stored at big ISPs is most likely easily accessible by governments.

Instead of using such a centralized infrastructure, we should be decentralizing Email in the same way our usual mail system works. When you go back looking at the development of email, it actually was meant to be exactly like that.

My suggestion for email therefore is this:

  • Get your own domain name to use for your email address. Be aware that public email providers like gmail.com, hotmail.com, etc. are the ones in charge of their domain names and can cancel them or your email address at any time. You should be the one in charge of your own domain name.
  • Run your own email server at home. While this might sound difficult, a lot of services and communities try to make this as easy as possible. Some examples would be iRedMail, Mail-in-a-BoxSynology Email Server and YunoHost. In case you've heard about or own a Raspberry Pi, there are two major projects making self-hosted services, including Email, on a Raspberry Pi as easy as possible: arkOS and FreedomBox.
  • Use a third-party email server only as a backup mail server. In case your Internet connection at home drops and your mail server is unreachable, configure a third-party email server as a backup, so your emails will be delivered regardless. In a best case scenario, you can set up a friend's home email server as your backup server and vice versa.
  • Use end-to-end encryption such as GPG to protect your emails even if someone else is able to access them.

This just a very brief overview of why I suggest hosting your own email server. There are lots of other things to consider and running an email server is by no means an easy task, I understand that.

As a concluding suggestion, I'd like to introduce the website PRISM Break which lists free and open alternatives for all kinds of proprietary and closed solutions. Specifically for mail servers: PRISM Break Mail Servers

In my next article I'll be taking a look at preference storage, where to save application preferences, what to do with browser syncing and phone syncing.

This article is a follow up to Germany's E-Pestbeef. I suggest reading that in case you haven't already.

I found a flyer for Deutsche Post AG's E-Postbrief in my mailbox the other day. I've found some of those there before but always tossed them immediately (with the rest of the advertisement crap I don't need). This time I actually went through it however. The idea was to have a laugh. Instead I ended up raging.

It is just ridiculous what claims they make in there. What upsets me the most is how they try to deceive normal people who have no clue about the matter into registering and using their "secure" system. I will comment on some quotes taken from the flyer. The original quotes are in German and I will include them in brackets after the translated quote. Let's take a look:

"Conventional emails are too insecure - you never know who else might be reading. Michael's solution: the E-Postbrief." ("Einfache E-Mails sind zu unsicher - da weiß man nie, wer alles mitliest. Michaels Lösung: der E-Postbrief.") - Aktuelles zum E-Postbrief 12/2011 page 8

So conventional emails are not as secure as the E-Postbrief. I beg to differ. First of all it depends on how you define "conventional email".

Let's say "conventional email" means unencrypted emails then I'd say conventional emails and E-Postbrief are pretty much on the same level. Yes, E-Postbrief uses encryption. But what encryption? We don't know. Who encrypted it? Not you.
Update: Actually this wasn't quite correct to prove my point. It's more like: Who decrypts it? Not you, they decrypt it for you on their system.
Meaning: a third party being not you nor the recipient knows how to decrypt the message. Insecure crap.

Let's say "conventional email" means an encrypted email with GPG/PGP. You created your key, the recipient created their key, there is no third party involved. The message has been encrypted with well known and proven security standards.

Which would you choose now? Of course they're not telling you that, though. This is exactly what makes me rage: they're telling people their system is secure and some who don't really know a lot about the matter will believe and trust them. However in reality their system is NOT secure at all. It's a freaking lie.

"Your documents are stored permanently and securely like in a giant safe at www.epost.de." ("Ihre Unterlagen sind bei www.epost.de wie in einem riesigen Safe dauerhaft und sicher abgelegt.") - Aktuelles zum E-Postbrief 12/2011 page 5

Yes, permanently alright. Since once you delete something it actually is not deleted. Securely, huh? Let's see...

"The high quality and security standard of the E-Postbrief platform is even approved and certified by TÜV." ("Der hohe Qualitäts- und Sicherheitsstandard der E-Postbrief-Plattform ist sogar vom TÜV bestätigt und zertifiziert.") - Aktuelles zum E-Postbrief 12/2011 page 5

This one actually makes me laugh and die a bit inside. Security certified by TÜV. Want to know software that has also been certified by TÜV?
Internet Explorer 8 and Internet Explorer 9 (OMFG, are those spaces in the URL?)
What a guarantee for security and quality! Trollolololol.

DON'T USE THIS SERVICE. I can't say it often enough. It is NOT secure, it is NOT private, it's all a big freaking lie.

Also have a look at this nice list of companies who apparently seem to be as incompetent as Deutsche Post AG (since they are all already using and supporting E-Postbrief).

At least they're maintaining a handy blacklist. Vote with your wallet.

Note: Due to copyright I'm not publishing the whole flyer on here. I have a copy however, in case you want to have a look at it, simply contact me.

Personally, I'm a fan of sarcasm, I just can't get enough of it. Some people are really good at it, makes me laugh sometimes, sometimes it just makes me sad however.
So as a short introduction to understand what I'm going to post, in case you're not familiar with the history of East Germany:
There once was a wall between West and East Germany (no shit Sherlock). Do note that all the quotes I'm posting are originally in German (see the original at the end of each quote).

About two months before the wall was built, an Eastern German politician, named Walter Ulbricht, said the following:

"Nobody has the intention of building a wall." ("Niemand hat die Absicht, eine Mauer zu errichten.") - Walter Ulbricht, 1961

A true master of sarcasm.

Lately there seems to be another politician mastering the arts of sarcasm in Germany, namely Wolfgang Bosbach. I've collected quite a few quotes of him already, so let's just take a look.

"Nobody wants to establish a surveillance state in Germany." ("Es hat niemand vor, einen Überwachungsstaat in Deutschland zu errichten.") - Wolfgang Bosbach, 2007

"Nobody wants to introduce scanners in Germany which optically expose the passenger." ("Niemand will in Deutschland Scanner einführen, die den Passagier optisch entblößen.") - Wolfgang Bosbach, 2010

And his latest addition, just few days old:

"We also don't want that the German armed forces will be converted to some sort of police assistance which can always be called when police forces of the German federation and states are overloaded." ("Wir wollen auch nicht, dass die Bundeswehr zu einer Art Hilfspolizei umfunktioniert wird, die immer dann gerufen werden kann, wenn die Polizeibehörden des Bundes und der Länder überlastet sind") - Wolfgang Bosbach, 2010

Convincing, if you ask me.

Sometimes however he kind of gets lost in his own scheme and actually says things how he truly intends them:

"We badly need a definite legal basis for law enforcement agencies to monitor encrypted communication of terror suspects via the Internet." ("Wir brauchen dringend eine sichere Rechtsgrundlage für die Strafverfolgungsbehörden, um auch verschlüsselte Kommunikation Terrorverdächtiger über das Internet überwachen zu können") - Wolfgang Bosbach, 2010

LOLWUT.

This country clearly needs more security! OMG, we're all going to die because people blow themselves up all the time!
On a totally unrelated note: Choot that pizza chit!

Read the original article "The "LOLWUT" moment" here if you haven't already.

In recent news: India also has access to RIM's BlackBerry Messaging codes for decrypting messages now:

"The Indian government press office is reporting that Research In Motion (RIM), the Canadian company behind the BlackBerry, has provided the government with an interim solution to enable Indian government agencies to eavesdrop on BlackBerry Messenger Service (BBM) traffic." - The H Security article

Fail.

So, to avoid banning of services in certain countries, because they are actually secure in a way, they simply go ahead and hand out their decryption codes. Excuse me for the harsh language but, what the fuck? Privacy? Non-existent anymore it seems. What's making me rage the most, though, is how all these companies advertise with secure and private communication, yet they support countries in eavesdropping on their citizens.

This is just one example, there are other companies doing the same. See Deutsche Post for example.
Instead of providing security and privacy, which is what they advertise for, these companies take a dump on their customers and support retarded governments spreading terrorist and security propaganda. It's just sad.

We all know what an email is, right? Germans had the great idea of reinventing the wheel, once again. In particular I want to talk about the "E-Postbrief" which is a new service by Deutsche Post AG.

First of all, what's "E-Postbrief" supposed to mean? The "E" stands for electronic, just like when talking about conventional emails. I was wondering how to translate "Postbrief" so I consulted a dictionary to help me out:

E = electronic
Post = mail
Brief = letter

So, that would make it "electronic mail letter". Awesome.

Now, what's the difference between a conventional email and this new E-Postbrief? You can send usual letters with it, either completely electronic (should your second party also use E-Postbrief) or have them printed and sent as a normal, written letter. Both options cost a minimum of 0,55€ though. Also the electronic delivery is limited to a size of max. 20MB. The idea is to have an email with legal ground, which is legally binding, so you can get doctor's bills, etc. via E-Postbrief and save them digitally instead of having to deal with printed letters.

My first thought: Hell no, I'm not going to pay 0,55€ for each mail. But really, that's still the least of my concerns with this service.
Because what I didn't mention so far: the service is supposed to be secure and encrypted!

And how does that work? Well, not with your own public and private keys like PGP or GPG, that's for sure. Instead, it's made simple for the average citizen. That is: Deutsche Post AG is doing all the work for you. They encrypt and decrypt everything for you. Anybody else noticing this weird smell?
In case you're at least wondering what encryption algorithms they're using, well, you won't know. Because they're not telling.
Security through obscurity. Except that this pretty much equals having no security at all.

Also they claim that it's "not possible" for Deutsche Post employees to read any E-Postbrief saved in your account. The second sentence corrects that down in a way though by saying it's secured against access by "unauthorized" people. Who is authorized?

In case you're still not convinced that this is some utter insecure crap, by accepting the terms of services you agree that Deutsche Post may forward your mails (unencrypted!) to law enforcement agencies in case public security is being endangered. (aka terrori- ohshit, I'm scared.) (9. 9(3))
Did I mention your emails are mirrored and not deleted once you delete them? Yes, that's right, they'll only be deleted after an unspecified period of time. You may not see them anymore in your inbox but they're still there. That's of course just because you might delete something by accident. (2. 2(5))

Because of all the criticism, Deutsche Post added a service so you can generate your own private key and a signature. Funny though: they claim this key is only accessible to you, but who guarantees that? The key is generated on their servers, you simply download it from them. The only way to have a real secure private key is by generating it on your own machine, not anywhere else.

I only raise one question: When they reserve the right to forward mails to law enforcement agencies in an unencrypted format, how is it not possible for any employee to read mails? They have the ability to decrypt them, they have the ability to forward them, but they don't have the ability to read them? Blind employees, the security concept of the future. Germany's always one step ahead.

So, to recap these awesome features of E-Postbrief: Costs money, insecure, totally unnecessary, insecure, did I mention insecure already?

Leave it, don't use it, is my suggestion. Stick to GPG/PGP and once again: Stay private.
