Ethereum: Can you store personal data in blockchain?
When it comes to storing personal data, many people assume that this is not possible due to the decentralized nature of blockchain technology. However, there are ways of secure private personal data, such as medical documentation.
What is blockchain?
Blockchain is a public book that records transactions in the computer network in a safe and transparent way. Each block in the chain contains a record of all transactions in it, enabling tracking of who has it when and where.
Can you store personal data in blockchain?
Technically yes, but with some reservations. Blockchain technology can be used to store private data, but not without certain restrictions and security measures.
One popular solution is to use “private” memory solutions that allows users to encrypt their data using their own private keys. These private keys are then stored in blockchain, which allows access to encrypted data, while maintaining public data outside the chain.
Examples of secure solutions for storing personal data:
- MEDIBLOC : A company specializing in storing medical records and is built on the blockchain platform. They use a unique encryption method called “Hash -based encryption” to protect user data.
2.
- Hashicorp Vault : Safe storage solution that allows users to encrypt their data using various encryption methods, including those built on blockchain ethereum.
** Why storage of personal data in blockchain is difficult
There are several reasons why storing private personal data in blockchain can be difficult:
- Security : As mentioned earlier, blockchain technology is decentralized and open to anyone who has access to the network.
- Consensus mechanisms
: Blockchains require consensus mechanisms, such as proof of work or proof of the rate to validate transactions, which can lead to gaps in security if they are not properly implemented.
- Data integrity : Ensuring data integrity in blockchain requires complex cryptographic techniques to prevent manipulation and unauthorized access.
Can you handle private personal data with Blockchain Ethereum?
Yes, it is possible to store personal data in Ethereum blockchain with secure storage solutions such as Medibloc or Docusign. However, these solutions usually require additional infrastructure, such as dedicated servers and security measures, such as two -component authentication.
To sum up, although there are ways to store private personal data in Blockchain, it is necessary to understand security restrictions and problems. Thanks to proper implementation and specialist knowledge, it is possible to create safe memory solutions that protect confidential data, while ensuring their integrity and availability.
Application
Storing personal data in blockchain requires careful consideration of security, complexity and decentralization. Although potential solutions such as Medibloc and Docusign are available, it is key to consider the advantages and disadvantages before implementing any solution. Always consult experts and carefully assess the risk and benefits before storing confidential blockchain data or other decentralized platform.
