 Welcome you all on my channel. I'm Dr. Ashmi Singh, Assistant Professor Department of Education, okay? Today I'm going to start a very recent and relevant topic and it is applicable to all disciplines, okay? And it is digital identity because many of my listeners are in of Hindi medium, hence I have to discuss it in Hindi and English both, okay? So let's start with digital identity. First of all, when we talk about digital identity, we should know that digital identity means that we are getting closer to each other, we know each other superficially, or it is known through words that what is digital identity? What is digital identity? Our identity is not only in the physical world, it is not in the real world, but in the digital world, we exist, our existence has happened, we are a part of the digital world in some way. As soon as you know about it, you will have an idea that yes, we are also a part of it, we also use it daily, but we may not pay attention to it in that way, when we get to know its matter, its literature, we feel that see how much work it takes and we should know it. So digital identity is such a thing that any educator, businessman, even businessman needs a lot of bankers, and education is in-built in all things, so it is necessary for us. So we should know about this term, what is digital identity? It is the body of information about an individual, organization, or electronic device that exists online. A very simple word to know is that there is no information about us, about an individual, about an organization, about an electronic device that exists online. Now for example, let's go to the bank, let's explain it further, then what is digital identity? Digital identity is the sum of all digitally available data about an individual irrespective of its degree of identity. Look, this is something to pay attention to, that all the data about us is digitally available, it all becomes a part of the digital identity, it becomes our digital identity, but irrespective of its degree of identity, it is not necessary that it is valid data. Then a digital identity is a set of digital characteristics and credentials for the digital world. That is, one of our identity is for the real world and one of our identity is for the digital world. And in the digital world, all the information about us, our credentials, our characteristics are existing online, that is what our digital identity is made of. Why do you need it, what is it, you will get to know about it. Okay, one special thing, as we saw the evolution of the industrial revolution, how? 1.0, 2.0, 3.0, 4.0, education 1.0, 2.0, 3.0, 4.0, up to 5.0, then just like that, there is a web as well, 1.0, 2.0, 3.0, just like that, the evolution of digital identity has taken place with us. And now what we are going through is the 3.0 phase, so what was 1.0, it is centralised, it is website centric, that is, like our education was done, teacher centric, learner centric, similarly, there is no role of consumer, user in the digital identity, whose role is website is the main, website centric and limited to privacy of users, limited to its capacity, then what comes in it, username, password, online search activity, etc. Okay, so this is our digital identity, according to 1.0, when we came to 2.0, then what happened, now it is decentralised, centralised, and now what happened, user centric, like our teaching is done, teacher centric, learner centric, similarly, digital identity is now user centric, and social authentication is necessary for that, transparent and flexible across internet, transparent is everything that will show us, if you have seen the same data feed, then Facebook login option on other websites, this is its example, then digital identity 3.0, in which we are lucky, in which we feel, what is it, which we experience, consumer centric, means it was user centric, now we are more specified, and we are working according to the consumer, why, because it is an internet economy, it was a knowledge economy, now it is talking about the internet economy, everything is on the internet, all transactions, all payments, now let's see, we don't pay attention, we don't know, we just superficially do this, we are paying from mobile, how are we paying, because everything is consumer centric in this world now, and what is it, utilised strong authentication like biometrics, now it is going according to your finger, your facial expression is taking, your facial recognition is, it is according to your finger touch, so this is very specific, according to the consumer, no one else can open your mobile, if you put that message, then and ensure anonymity, we have to ensure anonymity, and this next generation digital identity means at par, and example, payment providers such as Paypal, Google, Pay and all, everyone knows, everyone does it, but we just feel its application part in its theory, and sometimes it is romantic, how easy it is, everything is in this digital world, but what is going on behind it, digital identity is coming out from 1.0 to 3.0, then, concepts we should know about digital identity, if we are studying digital identity, what are the concepts, first, identifier, attribute, identification, authentication and authorization, these five are basic concepts which are related to digital identity, and we should know, what is identifier, it is clear from the name that it will help us to identify, what are the set of attributes, some of our attributes allow, and application domain to link the declared identity previously known to the system, that is, your data feed is in the system, we have given you an identity, and you will match it, that allows an application domain to link the declared identity, we are saying that if we are there, it will say, give your passport, give your I card, give your Aadhaar card, give your debit card, so it will check from the identifier, whether the system is the same or not, like our date of birth can also be our identifier, DOB, then attribute, something that can be associated with the individual, whatever date of birth, your social security number, Aadhaar card number, these are all attributes, then identification, identification means how it will be established, that you are the one who has your bank account, how we transfer the data to you, then identification is the process by which individuals claim their identity, we say, no, we are, now check this, so what do you want in the bank, what does it say, you have to check your signature, then put your account number, then it will check your details, then authentication, what is identified, but when we authenticate, then we will do the transaction, then we will transfer the data, or we will believe that you are talking about the same thing, that is, your digital identity is right, so what is the process, it is a process in which the claimed identity is verified, what are we doing in identification, we are claiming the identity, and what are we doing in authentication, we verify the claimed identity, like we are matching the signature, then what is in authorization, now we will give you authority, we will give you authority that yes, the data can be transferred, money can be transferred, resources can be transferred, it is the decision process that allows a person to perform certain actions based on the identifier, okay, so identify, attribute, identification, authentication and authorization, all these concepts we should know, if we are a part of the digital world and we have digital identity, then we are not, and why do we have digital identity, our work, our identity, which is still going on, can be done, no, it will be very difficult, why, because there are so many benefits live with digital identity, which are improving efficiency, no doubt, right, we sit at home, we do transaction, our money, time, effort, energy, everything is left, and it is more efficient, it may be a mistake in counting, but when you do transaction, it will not be a mistake, then minimizing cost, right, cost is effective in terms of money, I have told you, money, effort, time, energy, resources, even you will save petrol, you will not come anywhere, you will save the environment, petrol is also so expensive, then enhancing security, means if you are sending someone a message, then you will not be able to get money all the time, or if you need anything, then you will be worried that nothing will go wrong, but yes, it is secure, then better customer experience, one second may seem, if you have transferred money to someone, if the network is all right, then high level of accuracy, everything is so accurate, that it is a very romantic experience, and we all experience it every day, what are the barriers? There are some barriers that we and your digital identity are not able to keep, or there is a problem, yes, there are barriers, what are these? First of all, it is social barrier, why social barrier? Because if we look at it here, then socially, if there is nothing, then there will be a gender difference, that if you look at the data, then there will be a lot of women who will not have the foundation, and they will only be men, why? Because it is said that what is the need of your identity, or you do not have a job, because you do not have a bank account, because you do not have a bank card, and all the transactions are done by men, that is why, apart from this, there is also a cultural distrust, that no, no, we are not bank bank, we do not work with the internet, something will go wrong, we will do it ourselves, we will do it by ourselves, we will go to the bank, we will collect the money, we will go to the bank and take it out, there are such social barriers, economic barriers, there are economic barriers, we do not have good gadgets, we do not have laptop, desktop, mobile phone with internet facility, then it is, it can be difficult, it can be a barrier, then technical barriers are there, you do not have it, and technically you also have a very good mobile, Apple, but you are not able to utilize all its new features, you do not have internet banking, then it is a technical barrier in it, then organizational barriers, if your organization is supporting you that you have to go through digital identity, you have to use biometrics, then you sign it, then there is also an organizational barrier, then legal barrier, why legal barrier? because it becomes our legal personality if our digital identity is there, then legal issues also come in it to pursue, maintain and adopt digital identity, then what are the risks? there are two aspects of everything, there are two aspects of the coin, there are cross and cons, there are both, there are consequences, so there are a lot of benefits, but there are also losses, what are the losses? Cyber security risks, everyone heard about cyber fraud, cyber hacking, everyone heard about cyber attack, there are a lot of benefits, but there are a lot of consequences of cyber attack, your information is being misused, your digital identity, your digital identity is being masked, according to AI, desired identification is being done, about which you want, means there is a high level of fraud, there are high level of risks, similarly there is a privacy fraud, we have privateized our setting, but it has leaked, our data has leaked, our information has leaked, then this type of risks are involved in having digital identity, then financial crime risk, most of the risks are in financial crime, because everything is a game of money, so we will enter someone else's bank account, we will hack their password, we will do this type of work, and we will get money out of it, there are a lot of problems like this, then authentication risks, if we have told the wrong identity, the attribute is wrong, when the data has been fed wrong for the first time, then authenticate it, you can't do anything about it, your help, and unknown risks are also there, means there is a lot of such things that you don't know, and in the future you will know that this is also a loss, so this type of problems are with digital identity, then what are the measures to be safer, if we don't do it, then it won't work, we have to keep our identity in the digital world, without that we will fall behind, we will lack behind, and there are so many risks, so we should accept some measures, so that we can keep our safe digital identity, there are a lot of them, but I have noted a few things for you, use password manager, what do we keep the password, one, two, three, four, five, anyone will crack it, many people, maximum people keep the password, P-A-W-S-W-O-R-D, you don't have to worry more than this, but if you use password manager, then it is such a figure that nobody can remember it, nobody can crack it, and it will be safe in your system, so please use password manager for these, set up multiple identities, why should we use the same ID everywhere, if we are wrong, all the accounts will go away, so set up multiple identities, then enable two-factor authentication, if you want to turn on Google, that means your coach's notification OTP will come on your mobile, so if two-factor authentication happens, then it will be good, it means you can't open it without it, then avoid public Wi-Fi, we get Wi-Fi anywhere, so we are very happy, but now it has become very cheap, these are all the packages of Wi-Fi, at the beginning it was very low, so you can download some films, download some big files, but it can be dangerous, it can be risky, so we have to avoid public Wi-Fi, it itself says, if you are doing a transaction, first secure your Wi-Fi connection, so many things, so AI has told us, then be careful in filling personal data online, in any form, in any feedback form, we don't have to give personal data, if you are sure, that information is going in the right place, it has to be used in the right place, then you have to fill your personal data online, because once it went online, then it became public, so there are many things like this, which tell us how to keep digital identity safe, so our identity is digital, because we all have a basic card, what it says, it has connected the account number, everything is connected, it also has your fingerprint, so as you tell us the basic number, all your information is known, what is your date of birth, the important thing is that to authenticate the date of birth, the basic card is not made, but the DOB is also matching that this is our date of birth, that is because you told us what is the date of birth, okay, so it is a new topic and something new I have come to know, so I want to share this new information with all my viewers and learners, so be safe, have a digital identity and avoid all type of risks and be smart, smarter, okay, so thank you all and it is done from my side.
