கீழ்காணும் தலைப்பில் சில எண்ணங்களையும், உணர்வுகளையும், பதிவுசெய்ய வேண்டும். ஆனால் எப்போதி என்று அறியேன்.

  1. உணர்வுப்பூர்வமானதில்லாத உச்சாடனத்தினான வாழ்வியல் முறை
  2. உடல் நீத்தார் என்றுரைக்காத உயிர் நீத்தோர்

Know the Social Network that’s spun around you

December 20th, 2010 No comments
Social Networks have become a buzz in the contemporary world.  Most of us use them without understanding what they are and what they could do.  Basically, social networks are a platform the enable friends and family to be touch.  A good deal eh? Yes, it started just like that.  It started as a proxy for a pubs, playgrounds, parties where friends hang around.  Instead of going  for meeting a person, these social networks enabled friends to be in touch over instant messaging, blogging, scribbling, sharing pictures and videos by making use of the Internet technology.  This is definitely good, so far.  Do you know what else these social networks could do to you?  Let’s see some possibilities for an arbitrary ‘X’ whom you never know who that is:-
  1. Find your friends.  If you are little dumb, one can easily find your crush, hated ones, and what not.
  2. Find your likes and dislikes based on your messages, scribblings
  3. Know your places of interest based on what you have written about places, pointers on meeting spots that you chose to meet your friends, etc.
  4. Potentially know your neighborhood, by going through your blogs of scribblings about your neighbors or happenings in your vicinity.
  5. Find out what food you eat, and what you are allergic to.
  6. Find out what type of network connection you have, based on your connectivity logs.
  7. Find out paths from friends-of-friends for connecting an arbitrary person to you through your contacts.
  8. Find out which communities you belong to, and hence your social and professional networks
  9. Find out where you work, what your hobbies are.
  10. Find out where you studied, what you studied, what you aspire and where you are heading to; based on your professional community memberships, activity in forums, answers queries, etc.
  11. Find who you would meet, when and where based on your conversations
  12. Find out your mood swings, based on the vocabulary of your conversations
  13. Find out your pictures, and the pictures of the related ones in family and profession.
Remember something, whatever is meant to be private is never private in Social networks or any other electronic 3rd party services for that matter.  I have listed a very brief potential possibilities.  Please use these platform with fullest caution.

One side of the Internet researchers are working on “Internet Anonymization”, an idea to protect one’s identity; on the other hand, Internet giants are pushing “Social Networks” where they build intelligence on the so-called privacy of people.  What a weird world !?!

Tamil Steganography

December 3rd, 2010 2 comments

A nice discussion on Tamil steganography that is worth sharing.. 🙂

Udayasankar said:

Came via shakty’s blog, interesting note on tamil and cryptography.  would like to know of any specific instances where a cryptic text and associated decipher key is available in Tamil. Are there known historical incidents in Tamil History where a use of cryptographic keys and texts are available, say similar to English Queen Mary’s use of cipher text which indirectly led to her execution. Or the Caesar cipher for instance. Any incidents you can point out.

Sudarshan, as in your comments on the blog, I am aware that the siddhas and mystics used indirect language and metaphors to express themselves to their select cliques, but then that does not amount to more than children making up their own dialects to bypass their elders.  could you point out any place where a real mathematical technique is used? for instance are there kalvettukkal or temple inscriptions which are in code?

I was wondering if the tamil language did indeed have a crypto concept that has mathematical backing as sakthy seemed to imply on his blog.  From what he wrote I took it to mean that this was a possibility rather than an established practice. However, the need to hide data is a universal impulse and i wondered if indian science and math did have some background in this. as to why specifically tamil, I will explain in a later mail. i am already aware that the mystics both Tamil and others, (much like the scientists of the eighteenth and earlier centuries.  Leornado, Newton, Leibnitz) coded their discoveries in cryptic text.

My response is:

i am not of an opinion that tamil were doing mathematical modeling on things that they practiced naturally like breathing.  the concept of mathematical modeling and theoretical proofs are the ideas of the west. if i am correct, our forefathers were men of practice, primarily based on observation sciences.   people observed the neighborhood carefully and identified interesting patterns. and these patterns are then connected to suitable inferences that were derived based on more observation and tuning..  if i have equate that to the current technology, the word is “statistical machine learning” without the approximations and model fitting.

i strongly believe that our men had insights which are passed on to their students as experiences on insights instead of mathematically explaining their insight like the west did.  our men had methods to conceive and transmit ideas without words (ex: bhagavath geetha 800 stanzas transmitted from the krishna “character” to the arjunan “character”).  our men understood non-linear time that exists, unlike the linear time definition of the west.  our men believed and practiced thought process instead of scripts.

ofcourse encryption was used heavily in the past, just in term of metaphors, symbols.  our guys did not work at the character by character level, instead at the context and semantics level.  anything that is semantic is difficult to model because of the heavy polysemous tamil language.
