The Anonymity Paradox

Scott McNealy, the former founder CEO of Sun Microsystems, once famously remarked on Privacy : 'Get over it'. This was a very bold statement to make especially for the CEO of a reputed company but he nevertheless spoke out of his experience. Its almost ten years since that statement was made and anyone who even barely uses the internet today wouldnt disagree much with Scott, though all of us would still want to believe in a perfect world.

As an aside, Privacy and anonymity are closely linked though there are subtle differences. Anonymity is keeping ones identity secret while privacy can imply keeping identity plus other information secret. For the purposes of this post i will consider privacy and anonymity the same and use them interchangebly. Link
In my opinion, privacy and connectivity are complimentary ideas i.e. both cannot coexist. The moment you are connected to the internet, your privacy ceases to exist. I believe that this is an unfortunate but true fact and one that people often find hard to digest. But believe it or not, total privacy does not exist in a connected world. At some level, privacy is just like security i.e. there is nothing like total privacy just as there is nothing like total security.

I can offer many reasons for this :
  • Every time we do an online transaction and give out our Name, Address and Credit Card details, we are essentially "hoping" and trusting that the website will not leak out our data. Some informed users may go one step further and check if the website displays a secure logo like HackerSafe or McAfee Secure etc. Unfortunately, as detailed in this blog, it turns out that these certifications are mostly useless and can be easily sidestepped.
But name, address and credit cards are not the only definitions of identity and hence privacy. There are still many ways of inferring identity. A few of them are :
  • Almost all websites that you browse will always log your IP address which can always reveal you or your ISP or your Organization. That is, you can almost always be tracked back.
  • With the explosion of social networks and Wikis, we are getting into the habit of revealing too much information about ourselves, our families, pets and everything that was once personal to us to a much wider audience. This voluntary discloure of information is in effect resulting in very complex attacks on privacy as witnessed in the Sarah Palin and Paris Hilton case.
  • The notion of Googling for information has caught on so much that we inadvertently reveal "stuff" about ourselves to google when we type in the search bar.
  • Every time we open our gmail account and browse our emails, we also get with it some relevant advertisements placed alongside our emails. What this means is that there is a program out there that is parsing our emails and trying to "understand" us.
  • Websites that measure website usage statistics such as Google Analytics also impact privacy in some way by storing information about your visits to websites(tracked by your IP) on its servers.
All this is fine, but where is the paradox in all this?

To state simply, my Anonymity Paradox is :
While it is difficult to maintain anonymity on the internet for the common user, the same internet offers a magical cloak of anonymity for hackers.
I was myself amazed when this realization struck me. Users find it difficult to keep their identies secret but hackers get away with their mischief without hardly ever being tracked down. The big reason for existence of the malicious hacking industry is because of this cloakability that the internet offers. Purists might argue that the law has been able to track down hackers but i do not think they will disagree over the fact that the ratio of captures to hacking incidents is very apalling at best. Hackers typically get caught when they themselves make a stupid mistake which compromises their anonymity (for instance see how Palins hacker was caught).

So at one end we have people cribbing about privacy on the internet while at the other end we have bad elements basking in the glory of the anonymous internet. To me, it looks like this is the way it is going to stay. Just like fire does not know intent and it just burns whatever it is asked to burn, the internet just does what its being asked to.

Does this all make sense ?

A Linux solution for copying and burning DVDs

The following are my experiences with copying and burning DVDs on Linux. To summarize the experience in a phrase : "It was a walk in the park".

Operating System Ubuntu 8.04

Tools of the trade
  • k9copy (for copying DVDs)
  • brasero (for burning DVDs)
Installation
Installation in ubuntu for the above packages is as simple as
$ sudo apt-get install k9copy
$ sudo apt-get install brasero

Procedure
  • Insert DVD into tray and open k9copy.
  • Choose File -> Open. This will load the DVD and show the chapters and titles as shown below. Select all the titles that you wish to copy.
  • Select Action -> Copy. You will be prompted for a location where the final iso file will be saved. Make sure that you have disk space atleast 2 times the size of DVD.
  • Leave all the options in the below pane as is unless you know what those options mean.
  • Once the copy starts you will be able to view the progress in the right-side pane.
  • The copy process creates a folder called dvd and an iso image in the location specified earlier.
  • You can remove the folder dvd as it is not required during the burning process.
  • Now to burn the iso image, open brasero and select the option for burning iso images.
  • Insert and blank DVD and start the burn process.
  • Enjoy !
In my experience, i have copied 4 DVDs and burnt around 12 DVDs and the whole process took slightly more than half a day. There were absolutely no errors and the original DVD quality was maintained in all the copied DVDs.

Announcing another blog !

Hello dear readers (if any).  I have started another blog (with a better purpose this time). The blog is about Indians and our innovations i.e. Jugaadu Indians and our Jugaads. The inspiration for the blog came to me while reading an article in August 24 issue of The Week. The article is about Indian Ingenuity and our innovations (or colloquially called Jugaads).  The following quote by  Dr. R. Mashelkar puts everything in perspective 
"we should think of innovation as a movement. The I in India has stood for imitation and inhibition for far too long. It is high time it stood for innovation. And the best thing about this movement is that we have the jugaad energy of a billion of us to power it forward. "

The NEWS Equation

Our life today is controlled by media. Be it newspaper, television, radio or the internet, we depend on news for a lot of our day-to-day decisions and sometimes even blindly. This fact is well understood by Media companies, Governments and Businesses alike. Unfortunately, it is also being used actively to mislead the common man.  News today is no more the simple raw information but it undergoes a complex process of editing and mixing before being delivered. Thinking over it for some time, i feel that the Media companies operate a  huge mixer which continuously churns out news according to the following equation 

NEWS = x% Information + y% Hype + z% Personal Biases + w% Political Biases 

Different media companies use different values for x, y, z and w and yield different types of news. A case in point is the recent news about the bootup of Large Hadron Collider (LHC) in CERN. A channel called Aaj Tak in India ran a TV series which would have made a layman believe that the bootup of LHC would destroy the world.  In this case, their percentage of hype was very high and little factual information was presented. Even if they would have done a simple google search for LHC and the myths surrounding LHC, they would have realized that speculations about formation of massive black holes have been long dismissed by emminent Scientists. But the media today is more interested in their own TRP ratings and very little interested in presenting facts.

When will people learn ?

Airtel (one of India's leading cell phone providers) has recently tied up with Apple to offer the iPhone 3G in Indian market. Everything is good but is the following sort of sales pitch necessary to sell of iPhones?? Airtel is quoted here as saying :

"even the most deadly hackers on the planet won't be able to crack the
codes that support the iPhone's Airtel applications with rival company
SIMs."

My question is : WHY ???. Even if you really have provided tamper-proof security, throwing a n open challenge to the highly skilled and distributed hacker work force on the internet is nothing short of the proverbial "hitting the axe on your own leg". Such stunts may be good to test your products before entering the market but not once the products are already out there. Such stupidity has surely attracted the bees and its just a matter of time before the bees sting.
