SECURITY IN BLOCKCHAIN

"Blockchain technology creates a structure with innate security traits. It is based on the tenet of cryptography, decentralization and agreement, which guarantee confidence in the security.
Security means the state of being free from danger or threat. In steemit the meaning is preservation of ownership. It helps the users to maintain their privacy and it safeguards their data, information, documents etc. from others that means, only the user can have access to his/her data. By this the owner has the overall protection of his/her information.

Security may come in the aspect of keys, passwords, face recognition, biometric authentication, fingerprint, etc. So it will be personal when a user selects his password. So security has a crucial part in the protection of any kind of information.

RETRIEVE:

I got my keys after the registration on steemit. I got the keys in the form of long alphanumeric format. So it is very protected and secure. Also I got the keys in a pdf files. The digital file is saved in my google drive and can only be accessed by me.

KEEP MASTER

I have done that already. Because, I have already create my account. I saved my master password in my google drive, so nobody can have access to my master password. I know the aftermaths if I lost my master password. So I ensure that I do not lose my master it any way.
