Example 1
As shown in fig. 1, the present invention provides a method for securely storing data, comprising the following steps:
entering metadata: inputting medical original data;
encryption in the data transmission process: writing verification information in the data transmission process for encryption;
and (3) data server filtering: the data server filters the data;
data synchronization block chaining: packaging the transaction data and the verification information in the filtered data into a block at intervals, and sequentially connecting the transaction data and the verification information in series to form a block chain;
data is stored in combination with the blockchain hash value: and storing the hash value of the verification information of the previous block in the verification information of each block, and storing the processed data into a target database and simultaneously making a data identifier.
As shown in fig. 2, the present invention provides a method for reading data safely, which is used for reading data stored by the above method, and the reading method includes the following steps:
the reading method comprises the following steps:
sending a data reading request;
extracting the block chain abstract: extracting a timestamp and a hash value in the data storage identification;
block chain data penetration: verifying the data through the timestamp, and linking the verified data content by calculating a hash value to complete block chain penetration;
data encryption transmission: the data display penetrates to an encrypted data server through a block chain, and the encrypted data server transmits the data to the browser in an encrypted mode;
browser playback: the browser decrypts and displays the transmitted data.
Specifically, a data storage identification mechanism is provided by combining a block chain; data reading can only read data from the hash value of the storage identifier; the Hash value link block chain public chain ensures that data can be traced; the data display penetrates to the encrypted data server through the block chain; the data server gives out a true value of the data through a data encryption and decryption mechanism; making a data identifier while storing the data in a target database; when a public chain of a data synchronization block chain is formed, block chain abstract identification is made; on the basis of the algorithm of data encryption, a linear and nonlinear mixed encryption mode is adopted to ensure the safety of bottom data; the data server adopts the fragmentation storage, so that the data backup and the storage safety are ensured.
The invention solves the problems of data security and data right confirmation through a block chain, data encryption and database encryption comprehensive scheme.
The agreement is achieved by a consensus mechanism, advanced cryptographic algorithms ensure data security, and transaction data and verification information are packed in a block at intervals and are sequentially connected in series to form a chain. In the block header (authentication information) of each block, a block header hash value (parenthosh, parent block hash) of the previous block is stored. Such that the blocks in the block chain are linked to each other. If we change the content of a block in the previous period, the parent block hash of the following block is not matched with the parent block hash, and the block cannot be identified. This ensures non-tamper-ability of the blockchain data.
On one hand, the block chain authority is confirmed, and the originality and the advancement of the uploaded content are proved by adding a timestamp; on the other hand, after the content is uplinked by calculating the hash value, the right is confirmed quickly and simply, manual examination is far exceeded, and massive data is supported.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
