Note on Internet Privacy (Updated)and a note on DNSCrypt

I noticed the brouaha on Google’s privacy policy. I am afraid that social networks capture much more private information than search engines (even if they integrate my browser history, my social network, my emails, my search engine keywords) – I am still okay. All they are going to do is sell me better ads (maybe than just flood me with ads hoping to get a click). Of course Microsoft should take it one step forward and capture data from my desktop as well for better ads, that would really complete the curve. In any case , with the Patriot Act, most information is available to the Government anyway.

But it does make sense to have an easier to understand privacy policy, and one of my disappointments is the complete lack of visual appeal in such notices. Make things simple as possible, but no simpler, as Al-E said.


Privacy activists forget that ads run on models built on AGGREGATED data, and most models are scored automatically. Unless you do something really weird and fake like, chances are the data pertaining to you gets automatically collected, algorithmic-ally aggregated, then modeled and scored, and a corresponding ad to your score, or segment is shown to you. Probably no human eyes see raw data (but big G can clarify that)


( I also noticed Google gets a lot of free advice from bloggers. hey, if you were really good at giving advice to Google- they WILL hire you !)

on to another tool based (than legalese based approach to privacy)

I noticed tools like DNSCrypt increase internet security, so that all my integrated data goes straight to people I am okay with having it (ad sellers not governments!)

Unfortunately it is Mac Only, and I will wait for Windows or X based tools for a better review. I noticed some lag in updating these tools , so I can only guess that the boys of Baltimore have been there, so it is best used for home users alone.


Maybe they can find a chrome extension for DNS dummies.


Why DNSCrypt is so significant

In the same way the SSL turns HTTP web traffic into HTTPS encrypted Web traffic, DNSCrypt turns regular DNS traffic into encrypted DNS traffic that is secure from eavesdropping and man-in-the-middle attacks.  It doesn’t require any changes to domain names or how they work, it simply provides a method for securely encrypting communication between our customers and our DNS servers in our data centers.  We know that claims alone don’t work in the security world, however, so we’ve opened up the source to our DNSCrypt code base and it’s available onGitHub.

DNSCrypt has the potential to be the most impactful advancement in Internet security since SSL, significantly improving every single Internet user’s online security and privacy.



The DNSCurve project adds link-level public-key protection to DNS packets. This page discusses the cryptographic tools used in DNSCurve.

Elliptic-curve cryptography

DNSCurve uses elliptic-curve cryptography, not RSA.

RSA is somewhat older than elliptic-curve cryptography: RSA was introduced in 1977, while elliptic-curve cryptography was introduced in 1985. However, RSA has shown many more weaknesses than elliptic-curve cryptography. RSA’s effective security level was dramatically reduced by the linear sieve in the late 1970s, by the quadratic sieve and ECM in the 1980s, and by the number-field sieve in the 1990s. For comparison, a few attacks have been developed against some rare elliptic curves having special algebraic structures, and the amount of computer power available to attackers has predictably increased, but typical elliptic curves require just as much computer power to break today as they required twenty years ago.

IEEE P1363 standardized elliptic-curve cryptography in the late 1990s, including a stringent list of security criteria for elliptic curves. NIST used the IEEE P1363 criteria to select fifteen specific elliptic curves at five different security levels. In 2005, NSA issued a new “Suite B” standard, recommending the NIST elliptic curves (at two specific security levels) for all public-key cryptography and withdrawing previous recommendations of RSA.

Some specific types of elliptic-curve cryptography are patented, but DNSCurve does not use any of those types of elliptic-curve cryptography.


Does the Internet need its own version of credit bureaus

Data Miners love data. The more data they have the better model they can build. Consumers do not love data so much and find sharing data generally a cumbersome task. They need to be incentivize for filling out survey forms , and for signing to loyalty programs. Lawyers, and privacy advocates love to use examples of improper data collection and usage as the harbinger of an ominous scenario. George Orwell’s 1984 never “mentioned” anything about Big Brother trying to sell you one more loan, credit card or product.

Data generated by customers is now growing without their needing to fill out forms and surveys. This data is about their preferences , tastes and choices and is growing in size and depth because it is generated from social media channels on the Internet.It is this data that can be and is captured by social media analytics.

Mobile data is also growing, including usage of location based applications and usage of Internet from the mobile phone is leading to further increases in data about consumers.Increasingly , location based applications help to provide a much more relevant context to the data generated. Just mobile data is expected to grow to 15 exabytes by 2015.

People want to have more and more conversations online publicly , share pictures , activity and interact with a large number of people whom  they have never met. But resent that information being used or abused without their knowledge.

Also the Internet is increasingly being consolidated into a few players like Microsoft, Amazon, Google  and Facebook, who are unable to agree on agreements to share that data between themselves. Interestingly you can use Yahoo as a data middleman between Google and Facebook.

At the same time, more and more purchases are being done online by customers and Internet advertising has grown much above the rate of growth of other mediums of communication.
Internet retail sales have the advantage that better demand predictability can lead to lower inventories as retailers need not stock up displays to look good. An Amazon warehouse need not keep material to simply stock up it shelves like a K-Mart does.

Our Hypothesis – An Analogy with how Financial Data Marketing is managed offline

  1. Financial information regarding spending and saving is much more sensitive yet the presence of credit bureaus alleviates these concerns.
  2. Credit bureaus collect information from all sources, aggregate and anonymize the individual components accordingly.They use SSN as a unique identifier.
  3. The Internet has a unique number too , called the Internet Protocol Address (I.P) 
  4. Should there be a unique identifier like Internet Security Number for the Internet to ensure adequate balance between the need for privacy as well as the need for appropriate targeting? 

After all, no one complains about privacy intrusions if their credit bureau data is aggregated , rolled up, and anonymized and turned into a propensity model for sending them direct mailers.

Advertising using Social Media and Internet


1. A business creates an ad
Let’s say a gym opens in your neighborhood. The owner creates an ad to get people to come in for a free workout.
2. Facebook gets paid to deliver the ad
The owner sends the ad to Facebook and describes who should see it: people who live nearby and like running.
The right people see the ad
3. Facebook only shows you the ad if you live in town and like to run. That’s how advertisers reach you without knowing who you are.

Adding in credit bureau data and legislative regulation for anonymizing  and handling privacy data can expand the internet selling market, which is much more efficient from a supply chain perspective than the offline display and shop models.

Privacy Regulations on Marketing using Internet data
Should laws on opt out and do not mail, do not call, lists be extended to do not show ads , do not collect information on social media. In the offline world, you can choose to be part of direct marketing or opt out of direct marketing by enrolling yourself in various do not solicit lists. On the internet the only option from advertisements is to use the Adblock plugin if you are Google Chrome or Firefox browser user. Even Facebook gives you many more ads than you need to see.

One reason for so many ads on the Internet is lack of central anonymize data repositories for giving high quality data to these marketing companies.Software that can be used for social media analytics is already available off the shelf.

The growth of the Internet has helped carved out a big industry for Internet web analytics so it is a matter of time before social media analytics becomes a multi billion dollar business as well. What new developments would be unleashed in this brave new world is just a matter of time, and of course of the social media data!

Hacking Hackers

This is a ten step program to fight hacking attacks. You may or may not choose to ignore it, laugh at it, or ponder on it.

1) Internet security is a billion dollar business which will only grow in size as cloud computing approaches. Pioneers in providing security will earn considerable revenue like McAffee  , Norton did in the PC era. Incidentally it also means the consulting/partner group that is willing to work with virtual workers and virtual payments to offshore consultants.

2) Industrial espionage has existed from the days the West stole Gunpowder and Silk formula from China (and China is now doing the same to its software). The company and country will the best hackers will win. Keep your team motivated mate, or it is very easy for them to defect to the other side of the (cyber) wall.

3) When 2 billion people have access to internet the number of hackers will grow in number and quality much more rapidly than when only 100 million people across the world had access. Thanks to Google Translate, Paypal, Skype video Call, Tor Project, and Google Voice i can and have collaborative with hackers almost in all geographies. You can only imagine what the black hats are doing.

4) Analyzing hackers is like reading Chinese Tea Leaves. If you have experienced analysts, you will slip up. recruit the hackers in the dormitory before China recruits them using Lulz Security as a bogus cover. or USA recruits them as cover for spreading democracy in the Arab countries.

5) get your website audited for security breaches. sponsor a hack my website contest. before someone else does it for you.

6) Fighting hackers was always tough. But now we have part time hackers , people with perfectly respectable jobs who look like Mr Andersen and hack like Neo from the Matrix. Every kid once wanted to be a firefighter. Every geek dreams  of the one ultimate hack.

7) if you cant beat hackers, join them.

8) the more machine data is generated, the more you need external experts and newer software interfaces. Investing in open data, datasets is good. Keeping Bradley manning naked in his cell is bad. ignore the bad PR at your own cost.

9) Stop blaming China for every hack attack. You are a techie not a politician

10) Hack hard. Hack well. If someone hacks you, you will need to hack them off offensively unless you just want to be an easy mark for the rest of your lives. Counter -hacking expertise needs to be strengthened and groomed. hacking is an offense not just a defense game.



Data Mining Presentation at M2009 by Dr Vincent Granville

Here is a Data Mining Presentation by Dr Vincent Granville at M 2009.

I could not see the presentation as I know him only through remote internet communication, but he did recommend me on LinkedIn and for my application for the University of Tennessee.

here is the presentation on the docs on Google DOCs



Hey Doc,
How’s Paris doing.


The download is also available here.


ppps- He is the same person whom I worked last winter as a research ass is tant and got paid 28 cents per 1000 rows for all the statisticians in the world – read more about that here
