Advanced Data, Privacy and Protection

00:04.000 --> 00:09.000
In this video, we will understand advanced methods of data privacy and protection.

00:09.000 --> 00:15.000
Understand multi-factor authentication. Understand the role of encryption in data protection.

00:15.000 --> 00:22.000
Data privacy and protection focus on securing personal information from unauthorized access

00:22.000 --> 00:28.000
and ensuring compliance with privacy laws like GDPR and CCPA Act.

00:28.000 --> 00:34.000
It involves using security measures like multi-factor authentication and encryption.

00:34.000 --> 00:40.000
Let's understand multi-factor authentication adds extra verification to prove your identity

00:40.000 --> 00:46.000
like password authentication, biometric authentication using face or fingerprint

00:46.000 --> 00:53.000
and phone verification for pensigration. These are types of multi-factor authentication.

00:53.000 --> 00:57.000
Encryption and its role in data protection.

00:58.000 --> 01:04.000
Encryption is the process of converting readable data, plain text, into an unreadable format,

01:04.000 --> 01:08.000
Cypher text, using the encryption key.

01:08.000 --> 01:16.000
And decryption is converting encrypted data back into its original readable format using a decryption key.

01:16.000 --> 01:22.000
There are two main types of encryption. Symmetric encryption and asymmetric encryption.

01:22.000 --> 01:27.000
In symmetric encryption, one key is generated and distributed to both the sender and the receiver,

01:27.000 --> 01:33.000
via some key distribution protocol. The sender uses the key to encrypt a file that it sends

01:33.000 --> 01:38.000
and the receiver uses the same key to decrypt the file.

01:38.000 --> 01:47.000
So the word symmetric represents the fact that both the encryption and decryption are being done by the same key.

01:47.000 --> 01:54.000
Asymmetric encryption, in asymmetric encryption, the receiver generates the private and the public key.

01:54.000 --> 01:58.000
The public key is mathematically derived from the private key.

01:58.000 --> 02:02.000
However, deriving the private key from the public key is not feasible.

02:02.000 --> 02:08.000
The receiver then keeps the private key to itself and makes the public key publicly available.

02:08.000 --> 02:14.000
Now, the sender uses the public key of the receiver to encrypt the file that it wants to send.

02:14.000 --> 02:21.000
Remember, once encrypted, the file can only be decrypted using the private key, not the public key.

02:21.000 --> 02:27.000
Upon receiving the encrypted file, the receiver decrypts the file using the private key.

02:27.000 --> 02:33.000
So here asymmetric means that different keys are being used for encryption and decryption.
