Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electronic device and a method for verifying the integrity of data based on a block chain,

The present invention relates to an electronic device and method for verifying the integrity of data, which verifies the integrity of data stored in a server using a block chain.

In general, a blockchain is a non-forgivable distributed storage that is created and managed by a peer-to-peer (P2P) network. A block chain is a collection of data blocks created in a transaction (a non-breakable unit operation between the two parties) connected in a chain. Once recorded, the data can not be falsified or altered because the difference blocks in the previous block are consecutively encrypted and more than half of the user's agreed data is recognized as actual data. A typical example of a block chain is a bitcoin, which is a decentralized electronic money that records the transaction process of cryptography. In the block chain, a definite transaction history generated between users for a predetermined time can be stored. And many users have copies of the block chain, and transactions can be made public. In this way, only the transaction details agreed to by more than a half of the users are recognized as actual data, and can be stored in a block to be permanently stored.

Conventionally, a block chain is not utilized to improve the integrity of data stored in a server (e.g., a database). In addition to not detecting whether important data stored in a server has been falsified or altered using a block chain, The integrity of the system was not guaranteed.

Therefore, as the stability of the data stored in the server is required, there is a need to improve the reliability of the data stored in the server.

Various embodiments of the present invention may provide an electronic device and method for verifying the integrity of data that improves the reliability of data stored in a server based on a block chain. In addition, the integrity of the data may be verified in an electronic device connected to the server.

To this end, various embodiments of the present invention provide a server for verifying the integrity of data, comprising: a memory for storing at least one data; And a processor for grouping the stored data, chaining elements of the grouped data, and storing the chained data in a block chain.

Also, various embodiments of the present invention provide a method of verifying the integrity of data in a server, comprising: grouping at least one data stored in a memory; Chaining the grouped data; And storing the chained data in a block chain.

Also, various embodiments of the present invention provide an electronic device for verifying the integrity of data, comprising: a memory for storing a certificate received from a server; And at least one processor for requesting and obtaining elements of data stored in the block chain based on the stored certificate in a block-chain network, and verifying integrity by comparing the grouped data with the obtained elements.

According to various embodiments of the present invention, the stability of data can be improved by providing an electronic device and method for verifying the integrity of data stored in a server.

Further, the present invention can prevent the data stored in the server from being falsified or altered, thereby improving the reliability of the data.

In addition, the present invention can directly determine whether the user himself / herself is data integrity.
