Blockchain technology is a system to record information. By using this technology, we can record the information in such a way that no one can change or hack the information. It means that this technology provides a specific type of database. This database is different from the typical database. It stores the information in the form of blocks. After storing the information in the form of blocks, it chains them together. If new data comes into the blockchain technology, it enters it into a fresh block. After filling this new block, it chains it with the previous blocks. As a result, it ensures the chronological order of the blocks. We can store different kinds of information even in hard disk by using blockchain technology. Anyhow, in most cases, we use it to store the ledger for transactions.
Blockchain Technology and Privacy Protection:
When we relate blockchain technology to privacy protection, we consider three important things. First of all, there come private and public keys. The use of private and public keys is the most aspect of privacy in the blockchain. These keys ensure the security of the transactions between the users. For this reason, blockchain systems are using asymmetric cryptography. Each user will get its public and private keys. With the help of these public and private keys, it is almost impossible for the users to guess the keys of other users. This thing enhances the security of the data and saves them from hackers. The users can share these keys within the network to send and receive the assets. While sharing these keys, they should not worry about their privacy. These keys will not share the private data of the users.
Secondly, there comes a peer-to-peer network. Nowadays, if we make typical transactions, we have to rely on the central authorities. These central authorities hold the data of the users. Moreover, these authorities make transactions. Due to the data breach, the data of all the users are at risk. To save the users from this kind of problem, blockchain technology has introduced a peer-to-peer network. It transfers the data in the form of nodes. Before making a transaction, it checks the data of the senders. At last, there come zero-knowledge proofs. It is in the form of a consensus decision-making protocol. With the help of this security measure, both parties have to ensure the validity of the data.
Blockchain Privacy Systems:
Blockchain is ensuring the privacy of the users with the help of two privacy systems. The first privacy system of blockchain technology is a private blockchain. It is different from the public blockchain. This privacy system is available for all the nodes who want to download the network. The public blockchain has some concerns about it. According to a public blockchain, everyone can download the blockchain. As a result, they can get easy access to transactions. This thing will not enhance the privacy of the users. They should know that to enhance the security of these transactions, this technology is also providing an extra layer of security.
After the private blockchains, there come hybrid blockchains. This system provides flexibility to the users. By using this system, they can keep a specific piece of information either private or public. This system is also allowing the entities to store the data on the cloud. While storing the data on the cloud, they have to ensure the privacy of the data. In other words, we can say that the hybrid system has the qualities of both public and private systems. That’s why this system is more useful for users than the previous one.
Uses of the Privacy Controls of Blockchain for Privacy Protection:
We can easily use the privacy controls of blockchain technology for privacy protection. First of all, we are using it for financial transactions. As we know that the popularity of cryptocurrencies is increasing day by day. These are digital assets that we are using instead of flat money. Nowadays, we are facing lots of security concerns in the financial system. It means that lots of privacy concerns and threats are present in the financial system. Under such a situation, blockchain technology allows users to send and receive payments without thinking about these privacy concerns.
Secondly, we are also using it in the healthcare sector. Its reason is that we are observing data breaches in the healthcare records. After getting these healthcare records, they can misuse the data. Moreover, they can also change the healthcare records. As a result, the hospitals pass the wrong information to the patients. With the development of blockchain technology, hospitals have shifted their records the blockchain technology. As a result, they can easily enhance the security of their records. At last, we are also using it to enhance the security of the legal records. This thing is helpful to enhance the security of an individual. Blockchain technology will not allow hackers to temper the records.
Blockchain Technology and Privacy Concerns:
Research by a dissertation help firm shows that there are some privacy concerns about blockchain technology. The first privacy concern about blockchain technology is transparency. This technology is allowing the users to control their data without the involvement of third parties. Some people say that certain characteristics of blockchain technology can infringe on the privacy of the users. It means that malicious users can trace private and public keys. After tracing these keys, they can create lots of security concerns for the users. They can easily get access to the transaction history of the users.
The second privacy concern about blockchain technology is its decentralization nature. It means that it doesn’t have a central authority to check the malicious attacks of the hackers. They can easily hack the systems and escape. As this technology doesn’t have the involvement of a third party. That’s why we can’t stop the transactions of hackers. Another problem is that we can’t reverse the malicious transaction. The third privacy concern is relevant to the private keys. We are using private keys to get control of the cryptocurrency. If someone gets access to these keys, he can easily use your funds. That’s why users should try to save these keys securely. If they save these keys on the computer, they may lose these keys.
