Can Blockchain be the Iron Man of Data Security?

 


Recent incident in Cyber Space shown that how vulnerable the data is and how important data security is to the user or an organization. There are various mechanisms out in the market in terms of data protection.

What may be the reason for Data Thefts and Loss of Data Privacy?

Lack of privacy towards the system is becoming more vulnerable to data thefts. For example, using weak passwords and lack of application regarding Cryptography.

Cyber Criminals are finding the vulnerabilities in the system like Thanos finding the Infinity stones.



Blockchain is the Iron Man of the Data Security. Blockchain Architecture will help reduce data theft and data tempering.

What is Blockchain?

Blockchain is growing list of records called blocks which are cryptographically hashed with pervious block. Blockchain follows the Merkle tree Data Structure



Merkle Tree: In cryptography and computer science, a hash tree or Merkle tree is a tree in which every leaf node is labelled with the cryptographic hash of a data block, and every non-leaf node is labelled with the cryptographic hash of the labels of its child nodes. Hash trees allow efficient and secure verification of the contents of large data structures. Hash trees are a generalization of hash lists and hash chains.



How is the Data Security ensured through Blockchain?

Blockchain is mainly classified into two architectures:

1.Permissionless Blockchain

2. Permissioned Blockchain

Permissionless Blockchain

Permissionless blockchains are blockchains that require no permission to join and interact with. They are also known as public blockchains.

Permissioned Blockchain

Permissioned blockchains can be seen as an additional blockchain security system, as they maintain an access control layer to allow certain actions to be performed only by certain identifiable participants.

In order to ensure a safe environment for an user or an organisation we take permissioned Blockchain.

Here, the data is stored in blocks (Data can be login details, User details etc). Once this data is stored in block it is cryptographically hashed with pervious block in the network. Once the data is can be changed or modified. Because it is a permissioned blockchain, it can be accessed only through private key of the user and the access to database is restricted has it permissioned network.

Now, even Thanos cannot delete the data with the snap


Doctor Strange’s time stones cannot modify the data by going into past.


Data stored in Blockchain is has strong secured has Vibranium metal (#Blockchain forever)

So we can call Blockchain has Ironman Data security or Cyber Space
