complexity of anonymity

i was working on a problem to reduce the complexity of anonymising structured data, to ensure the privacy of individuals and achieved a factor of O(n) an improvement over the previous best solution which promised a complexity of O(nlogn)....(for all the non-geeks ... i somehow promised to solve this problem in a shorter time...:))......

So you must all be wondering , why the hell i am boring you to death by telling this....well coz all of us at some stage in our life have try to suppress various "key attributes" of ours ... so that we can hide our past. We dont want others to let know ...about the events which took place in our lives...may be we all are scared ..of what ???..well we should ask ourselves , if hiding your problems and difficulties can solve them , then i don't think there would be any in this world , sadly it's not the case......

The mask which we wear keeps on changing ... in front of our parents,relatives and our friends...we always try to project a cool image of ours... the "james bond" type ... but when this mask is revealed ... we stand in front of them ... naked and not able to look straight into their eyes....so we ignore them ....but for how long ???...... we all wish that we are able to suppress some critical information of ours so that others don't know about us .... we wish that "anonymizing" oneself is as easy as the solution that i somehow have been able to arrive in theory of mining...

But life's no dataset or a corpora that than be tailored and clustered to our wishes, we can't bulit training sets that function according to our commands. Training sets normally put data in data into two "portions" left or right ... but the opinions of people and their thinking can't be binary .... its between o and 1 .... and not 0 and 1.... no matter how long one try to cover one self with the veil .... this veil will reval our true face..... so it's better we dont try all this crap in our life's ...coz emerging out it can take ages... we may try to present a happy face... but deep inside we know how this can slowly eat our happiness .... so it's better to be your true to one self.....

So anonmyzing our key attributes can suppress some of our characteristics... but we forget ...that combination of our other attributes .... the so called "quasi identifiers"...in the language of database can reveal the facts we have tried to hide .....it's like a cat and dog race... i may have promised to solve the theoretical problem in O(n) time.... but some day , others will reduce the complexity further .... bringing out ways where this anonymity can be "unmasked"... and then proposing another way to anonymizing ourselves... but in the end we all are running a race , where we know that we will eventually loose..... so live as u want ... to live ..... GTH everyone......

PS: i may have used some jargons ...which are used in computer science theory ... but i hope everyone gets the point....

A.L.O.N.E

There comes a moment in one's life , one when realises that he has to fight his battle for survival alone. The friends on which i had counted on my past , either betrayed me because i could not match up to their "so called" high standards or they moved on in life. I know that this feeling has some thing to do deep inside my head , may be the neurons are exercising a lot , and they need some rest....or may be they have emerged out of the smoke screen which was built because of my own whim's and fancies..............

So why the hell do i need to be with someone ??..... i had always though that living alone and focusing on my career goal; would bring happiness to me ....though i took a longer path to achieve my aim ...but i can surely bet it was worth the effort .... but now a felling of loneliness has begun to bite me deep inside.... though i have i achieved success , but it has come at a cost ...a cost where i have no one to share my success with , may be i don't feel the need as i always thought the whole world was perhaps against me ...or may be it was the driving force , which i myself created to accelerate on towards my target (some physics fundaas.....).. .People say that happiness is inside you , but what the hell ... haven't been able to retrieve it...and i am sorry none of data mining stuff works here...

My "so called" friends say that i have changed , i have become more reclusive and introvert .. i hardly log into the stupid "gtalk" once in 20 days ... and that too talk to one of my closest friends (i know he would get a clue when i force him to read this .... ) .. well i dont feel the need to waste my time on this crappy messenger where people unnecessarily ping you ...why the hell do i need to answer them . I find more solace in reading "multivariate chebyshev inequality" than all this stuff.I realise that it's good to move on in life and forget your past .. but whenver i try to do it . it comes back haunting in my dreams .. people like should realise that everyone moves on in life , the realtionships you had developed also transcend up and down ( mostly it was down in my case)...but deep inside my head i should realise that may be it's for my good ....others have their own life and i should not impose myselves on them and i also expect that they do the same ... may be it's all in between the ears.... I need to realise that i am what i am and dont' expect to live the life of others .... as my friend tells ... "you should start enjoying life!!" ...... i would surely take his cue....

I know that i have written this post haphazardly without paying due to the single point i wanted to say .. may be its a reflection of my mind .... i think a lot, and to stop it.. and start doing things which take away my boredom.... i had bulit this feeling that one is happy with so many friends around talking with them ... hours and hours on phone ... but in the end you achieve nothing out of it ....... perhaps these few lines cover the jist that i have some how failed to put through this post....


In ode to the sweet sands of time,

I hear a promise made by a friend of mine:

Vast as may be the distances to gain,

She will turn back time to come meet me again.

Whiffs of this gale will revisit my memory,

But will carry with them a scathing accessory.

Yet when I take a fond trip down the memory lane,

I‘ll want to trace back my steps and come meet you again

But then you realize………………………

When you look around you, you are all A.L.O.N.E …………………………
