I want to talk about something that many of us hold very close to our hearts (literally). I’m not sure if we all love them but we all do have them. In case you haven’t guessed it yet, well its ID cards that I want to talk about! We spend a majority of our time each day at work, and all throughout this time, we use a Magnetic/electronic card that determines our boundaries, our realms! Does this end here? Not really! Whenever we try to open a bank account, take membership in a club, register for anything at all, we are asked to produce proofs of identity! Even in the olden days, messengers and ambassadors of kings used to carry some kind of identity to prove that they represent a particular King/Kingdom. But then, they carried Identities to prove whom/what they represent and NOT who THEY were?To look at this from a practical angle, I present myself in a place but I need different kinds of identities to prove that I am ME. I cannot stop wondering as to, what better proof can I provide that I am me, other than presenting myself in flesh and blood. I repeat ‘what better proof can I provide that I am me other than presenting myself’. The system cannot recognize me from myself, but can recognize me from a piece of paper or a card? What a strange position for one to be in! Will it not be great if my office premises identified me not using my ID card, but using myself? How great it would be if these systems identify me using my own self?Sounds great, but too fictitious, in it? Not really… here is why!Let’s try to find out what inspired people to develop hi-tech systems like the identity systems that I was referring to earlier. Computers are basically tools that could do jobs that are repetitive, ones that have a pattern. So, if any of us were attempting to invent a computer to add two numbers, it would use the same method that we normally use. Computers came into existence just to automate the repetitive jobs that we already knew how to perform.Just a couple of examples to validate this claim!Those who have spent enough time in India, would have visited a tea-shop sometime and observed how tea is made in such places: The person would get the glasses (lets say 5 of them) ready, add sugar to each of them, then tea and then some milk to each glass and there you go, tea is ready for 5 waiting customers and none of them would have felt that they weren’t given priority. What kind of processing is this? You guessed it right! Is this not ‘Time Sharing’? Is this not something that we naturally tend to do, when we had to attend to more than one request at the same time?Maybe not from a teashop, but the scientists who formulated the time sharing concept in computers could have been inspired from one such instinctive action that they might have done or noticed when people had to cater to multiple requests. Quite Possible!Let’s look at another example of one such instinctive human behaviour that most of us would have experienced. This is an everyday happening in a crowded area such as a fast-food shop. We go in small groups. Pull in those moulded chairs and sit together for lunch. One of our friends goes back to the buffet, and we just sit in a way that we touch the empty chair slightly. People around looking out for a chair would not ask for this empty one. Sometimes, our friend changes his mind, signals to us that he is done with his lunch and rushes back to his desk. We just make a very slight adjustment to our posture distancing us from the empty chair and the next moment somebody else takes up the chair, because they could understand that you do not want that chair any more.In the situation I described above, we had limited resources shared by multiple entities. As long as the resource was needed by an entity, it posted a signal to other entities that it is holding that resource and once the need for that resource ceased to exist it released it by ‘signalling’ that this resource is up for grabs! Is this not what we call as ‘Semaphores’ in Operating Systems terms? Are they all not concepts taken from the real world?Let’s get back to where we are today. If complex concepts like Time Sharing and Semaphores could have been inspired from intuitive actions like this, we would agree that creating a digital realm is indeed doable. To identify our friends and acquaintances we do not ask for identity proofs, but we recognize them. We have patterns in our brain about the various attributes of an individual, the combination of which uniquely identifies him/her to us. This could be automated as well. This identification system would record different attributes of an individual, combining which it can identify him/her just as we humans do. The attributes recorded for each individual could be many, and different attributes could be matched at different places, depending on the security needs. This information could also be updated when required.If and when such systems are in place, this world will seamlessly, identify ‘me as me’, without demanding any kind of proof. No passports, no ID cards, nothing at all. If an individual were to be allowed into a country, let’s say, Egypt, the permission to enter checkbox against Egypt in his/her profile will be checked and everything else happens by itself. Paperless work indeed!
