Keywords

💡Privacy

Privacy in the context of the video refers to the individual's control and ownership over their personal data. It is a fundamental right that is essential for maintaining freedom and the integrity of free societies. The video emphasizes the importance of privacy as the foundation of a secure digital interaction, where individuals have the right to decide what information about their identities to share and with whom. For example, the script mentions that 'privacy to us is a basic human right and it's the foundation of freedom and free societies.'

💡Blockchain

Blockchain is a decentralized digital ledger that records transactions across multiple computers in a secure and verifiable way. It is the underlying technology behind cryptocurrencies like Bitcoin. The video discusses the design principles of blockchain, particularly its role in enhancing privacy by disentangling identity from transactions, which is a significant departure from traditional systems that require identity verification. The script illustrates this by stating, 'the blockchain doesn't need to know who anybody actually is.'

💡Satoshi Nakamoto

Satoshi Nakamoto is the pseudonym used by the unknown person or group who created Bitcoin and its underlying blockchain technology. The video credits Nakamoto with the breakthrough of creating a system where identity is not required for transactions, thus enhancing privacy. The script mentions, 'when Satoshi Nakamoto created the Bitcoin blockchain he installed no identity requirements for the network.'

💡Cyber Clones

The term 'cyber clones' in the video refers to the virtual representations of individuals created by corporations through the collection and analysis of personal data. These digital replicas may know more about an individual than the person themselves, as they are based on comprehensive data mining. The script warns, 'corporations can create what we could call cyber clones of people, the virtual you, by fracking the digital world for their data.'

💡Surveillance

Surveillance in this context refers to the monitoring of individuals' activities, often without their knowledge or consent, by entities such as corporations or governments. The video discusses the risks of surveillance societies, where privacy offenses lead to the collection and misuse of personal data. An example from the script is, 'even democratic governments are creating surveillance nations.'

💡Data Breaches

Data breaches are incidents where unauthorized individuals gain access to sensitive information, often leading to the exposure of personal data. The video cites several high-profile cases, such as eBay and JPMorgan Chase, to illustrate the scale and impact of such breaches. The script states, 'the scope of the recent data breaches is enormous.'

💡Pseudonymous

Pseudonymous refers to the state of having a false or substitute name, especially online. In the context of blockchain, transactions can be made under pseudonyms, protecting the real-world identity of the participants. The video explains how blockchain allows for pseudonymous identities, as 'users identities are also pseudonymous you have to triangulate a considerable amount of data to figure out who or what owns a particular public key.'

💡Public Key

A public key in cryptography is a part of a key pair used in asymmetric encryption. It is meant to be shared and can be used by anyone to encrypt messages or transactions. The video explains that on the blockchain, transactions are associated with public keys, which adds a layer of anonymity. The script mentions, 'with every transaction the sender can provide only the metadata that the recipient needs to know.'

💡Honeypot

In cybersecurity, a honeypot is a security mechanism set to detect, deflect, or study attempts at unauthorized use of information systems. The video uses the term to describe the accumulation of personal data that becomes a target for hackers. The script warns, 'then they fail to protect the Honeypot of all these data.'

💡AML and KYC

AML stands for Anti-Money Laundering, and KYC stands for Know Your Customer. These are regulatory requirements for financial institutions and certain other businesses to verify the identity of their customers to prevent fraud, money laundering, and other criminal activities. The video explains that while blockchain transactions can be pseudonymous, entities like online exchanges are still subject to these regulations. The script states, 'that exchange is required to do its due diligence under anti-money laundering, AML and KYC requirements.'

💡Anonymity

Anonymity in the video refers to the state of being unidentified or unknown, particularly in the context of online transactions. Blockchain technology allows for a degree of anonymity that traditional financial systems do not offer. The script explains, 'participants can maintain some personal anonymity they don't have to attach any other details to their Identity or store those details in the central database.'

design principles underlying blockchain

our fifth principle is privacy people

should control and even own their own

data period people ought to have the

right to decide what when how and how

much about their identities to share

with anybody else

respecting one's right to privacy is not

the same as respecting one's actual

privacy we need to do both

by eliminating the need to trust others

Satoshi also eliminated the need to know

the true identities of people in order

to interact with them

the problem this solves is huge it's in

keeping our own information under our

own control

privacy to us is a basic human right and

it's the foundation of freedom and free

societies

in the last 20 years of the internet

Central databases in both public and

private sectors have accumulated all

sorts of confidential information about

individuals and institutions sometimes

without their knowledge corporations can

create what we could call cyber clones

of people the virtual you

by fracking the digital world

for their data this virtual you may know

more about you than you do because you

can't remember what you did a year ago

or what you said a year ago or body or

go or your exact location or what drugs

you took or diagnosis was made by your

doctor or what test score you got or

even what your heart rate was the

trouble is that the virtual you

is not owned by you your identity

is owned by large corporations even

democratic governments are creating

surveillance Nations you can see how the

U.S National Security Agency

overextended its surveillance rights by

conducting warrantless spying over the

Internet these privacy offenses are

double violations first

these entities collect and use our data

without our knowledge or consent

then they fail to protect the Honeypot

of all these data

the blockchain Breakthrough is in

disentangling identity from transactions

when Satoshi Nakamoto created the

Bitcoin blockchain he installed no

identity requirements for the network

layer itself

no one has to provide a name an email

address or any other personal data in

order to download and use the Bitcoin

software

the blockchain doesn't need to know who

anybody actually is

that's also how swift the society for

worldwide interbank Financial

telecommunications works if you pay in

cash then Swift doesn't generally ask

for identification

still I wouldn't be surprised if many

Swift offices of cameras and Swift

requires financial institutions to

comply with anti-money laundering or

know your customer requirements

so there's still a certain lack of

privacy there with the blockchain the

identification and verification layers

are separate from the transaction layer

that means

Amy broadcasts the transfer of Bitcoins

from Amy's address to Bobby's address

there's no reference to anybody's

identity in that transaction then the

network confirms that yes Amy controlled

the amount of Bitcoin specified and

authorized sending it to Bobby

at that point it recognizes Amy's

message as unspent transaction output

associated with Bobby's address

only when Bobby goes to spend that

amount does the network verify the Bobby

Now controls that Bitcoin compare that

with using credit cards

credit cards are very identity Centric

your name your address your financial

information your personal identification

number your PIN they're all attached

that's why millions of people's

addresses and phone numbers are stolen

every time a database gets breached

the scope of the recent data breaches is

what's enormous eBay

145 million

Anthem Blue Cross Blue Shield 80 million

JPMorgan Chase 76 million and so on

there were also similar breaches of

telecom companies Airlines universities

Gas and Electric utilities Hospital

facilities some of our most precious

infrastructure assets on the blockchain

participants can maintain some personal

anonymity they don't have to attach any

other details to their Identity or store

those details in the central database

and this is huge

there are no honeypots of personal data

on the blockchain blockchain protocols

allow us to choose the level of privacy

that we're comfortable with in any given

transaction or environment

it helps us better manage our identities

as we interact with the world well

blockchain is public users identities

are also pseudonymous you have to

triangulate a considerable amount of

data to figure out who or what owns a

particular public key

with every transaction the sender can

provide only the metadata that the

recipient needs to know

moreover anyone can own multiple public

private key sets just as anyone can have

multiple devices or access points to the

internet or multiple email addresses

this complicates the tracing of data

back to any one person or any one

Institution

that said internet service providers

like Time Warner do keep records linking

identities to accounts likewise if you

get a Bitcoin wallet from a licensed

online exchange such as coinbase that

exchange is required to do its due

diligence under anti-money laundering

AML and kyc know your customer

requirements governments can subpoena

isps and exchanges for this type of user

data but they can't subpoena a

blockchain itself

that doesn't mean anonymity is required

we could design higher low levels of

transparency into any application into

any business model or set of

transactions should all the stakeholders

agree that that's a good idea there are

some situations where radical

transparency makes a lot of sense when

companies tell the truth to their

customers shareholders or business

partners they build trust the ideal

situation is privacy for individuals and

transparency for organizations and

institutions and public officials

so what are the implications of

blockchain's privacy safeguards

blockchain provides a defense against

the incoming surveillance Society think

about the problems that corporate Big

Data pose to each of us

what does it mean for a corporation to

have perfect information about you

or some 20 years into the global

internet era

but only at the beginning of corporate

access to the most intimate details of

our personal lives and ultimately our

body and our dnas and these details are

piling up personal health and fitness

data our daily comings and goings the

inner lives of of our families and our

homes you name it

many people are simply unaware of how

much privacy they bargain away every day

we leave these Trails of digital

Footprints crumbs

Footprints website owners can convert

into detailed maps of our whereabouts

with blockchain technology

we retain much more ownership over our

data we can protect our personal

information giving away only what's

required in any social or economic

Exchange

anytime we choose to give data of value

we can be compensated for it as well
