$150.
That's how much your name, date of birth, address, email and phone number were worth roughly 10 years ago on the black market.
Today, according to the Financial Times, your data is worth less than $1.
See how cheap your now Why?
Well, because today we're more open towards sharing our personal information than ever before.
And even if the dollar is not that much to lose, being impersonated and having, for example, a credit card or a mortgage opened on our name or your reputation being compromised will cost you much, much more.
We often hear that big data is the world's newest natural resource that needs to be mined like gold and diamonds.
And I agree our data can offer all kinds of personalized service is for the greater good.
But if big data is a natural resource than our personal data is, it's refined currency.
So why should we just freely give money away?
Would you just throw your money out of the window every day?
It all comes back to control, having control over who has our data and how it's being used in Switzerland, where I leave and in Europe at large data.
Privacy is a hot topic, and it has been for the past 50 years.
For that reason around.
The decade ago, the European Commission funded the research project called Prime to develop a cryptographic technology that would enable Europeans to verify who they are online without sharing their personal information.
And let me repeat that because it sounds like a paradox enable people to verify who they are online without sharing their personal information.
Think about how many times you log into different websites.
Either revealing your personal data directly or letting them track your history and habits one day accounted for myself.
It was like 25 Loggins to email social network shopping.
That's a lot of times we put ourselves out there, and not only online in the U.
S.
You often have to show your driver's license or some kind of proven identification to purchase alcohol.
If you look on the 21 and actually many places around the world, even people who are 30 or 40 years old still have to show their I d.
Well, I guess some people might see that as a compliment.
I do.
But when you show your driver's license to a cashier or bartender.
Think about how much bribe data you, which is giving away.
The fact is, you only need to prove that you're over 21 yet you offering your full name address, not to mention the food date, month and year of your birth at data thieves stream.
But what if we could just mask all this information and have our D card simply say she's older than 21?
Or the card is valid or simply, yes, with cryptography, we can we call it the zero knowledge proof.
And just like It sounds, you're nothing about the details of that person while still getting the proof to address the request.
So think about the famous Rubik's Cube.
How can I prove to you that I can sew it without revealing my technique?
So with Rubik's Cube, it's quite simple.
I just turned around, sold the Q and give it back to you.
So now it just proved that I can solve Rubik's Cube without revealing my technique.
By what about my age?
How can I prove to you that I'm old enough without revealing my date of birth?
Well, nowadays, it's also quite simple over the past couple of years we've been developing Web service is that can be easily used by the end users and service providers to enable privacy preserving authentication.
So how would that work in an online scenario?
Well, the first thing we need is an attribute or identity provider.
It can be a state authority that issues I D cards or any other organization that already has the data and can 35.
So for the zero knowledge proof toe work, they will need to issue you an Elektronik identity.
Or we called a cryptographic credential that can sit on your mobile phone PC were even in the cloud.
And this is crucial stare because later, when you use your credential, you can't lie about how old you are or who you are on.
Actually, different kinds of electronic identities are available, ready more than 18 countries.
So next think about this service.
You want toe access.
Think about an online consultation with the doctor, governmental social or tax services, or better think about the service is you don't want your Children toe access.
So think about all kinds off service is that require some kind of verification websites that alcohol or adult content or even a movie service.
So let's say you like to watch a movie that's rated R, so you need to prove that you're over 17 to watch it.
So in the past you would have to show your full credit card or four I D.
Or your kids could just simply take the check box on the website without any verification.
But with our technology, you can just simply logging to the website Seymour like you would do with a social network provider but in a much more privacy friendly way.
And then you will be asked, Would you like to prove to the movie service that you're older than 17?
And if you confirm, then the crypto will do all the magic transforming your full Elektronik identity into a fresh a link, a ble proof that Onley reveals that you're 17 years old and nothing, nothing else.
And it's very important that your identity identity provider does know about how you use your credentials, because all this computation is down locally on your device, and now only you have control.
Which data leaves your device and where it goes.
This is actually not only win for the user's, but also for the service providers because now the service provider just doesn't know anything about me, all the other than them.
Old enough.
So if all this information gets hacked from their service, the hackers who get nothing off value and these extras seif service providers from a potential PR nightmare, not to mention the financial damages.
According to Pawn Iman and Independent Security Institute, a damage from a lost or stolen record containing personal confidential information is around $150 which is fine if you have like just five clients.
But for a company with 100,000 clients, it's a 15 million penalty.
Well, sounds like magic and seems complicated while it waas when it was just invented 15 years ago.
But a few months ago, with changed this, we put the coat in the cloud and a mobile devices, and now the application developers can just simply copy and paste the court into the APS and their privacy friendly in seconds.
So what does this mean for the future?
While obviously these data leak hacks and identity thefts that we read about regularly will no longer be headline news, but now you might be thinking, Maria, your technology sounds really great, but my date is a radio there, so I'm an open book.
But cryptography can change this.
We can start sharing our data more carefully with people and service's and putting less data to a fewer places.
We reduce the risk.
Actually, we all change our phones for numbers and credit card numbers, even now, habits and hobbies.
So moving forward, we can get back the full control.
Money's not everything.
And I think that our personal data is much more than just a currency.
With the privacy preserving technologies, we can get back to control and actually value our personal data properly.
So let's make the Internet is safer place.
Thank you.
