Secure management of data files using a blockchain

A system for data file management, the system comprising:

• one or more processors;
• and
• one or more memory devices in communication with the one or more processors, the memory devices having computer-readable instructions stored thereupon that, when executed by the processors, cause the processors to:
• generate a genesis block for a data file management blockchain, the genesis block including a data file to be managed;
• sign the genesis block to commit the genesis block to the data file management blockchain;
• generate one or more transaction data blocks for the data file management blockchain, each transaction data block including a modification to the data file;
• sign each of the one or more transaction data blocks to commit each of the one or more transaction data blocks to the data file management blockchain;
• receive a request to edit the data file from a first entity, the request to edit including a modification of the data file and an identifier corresponding to the first entity;
• responsive to the request to edit, send an edit request to a second entity for the data file, the edit request including the identifier corresponding to the first entity;
• receive a confirmation message from the second entity with a signature;
• and
• sign a transaction data block corresponding to the request to edit with the signature received in the confirmation message.

A computer storage medium having computer executable instructions stored thereon which, when executed by one or more processors, cause the processors to execute a data file management method comprising:

• generating a genesis block for a data file management blockchain, the genesis block including a data file to be managed;
• signing the genesis block to commit the genesis block to the data file management blockchain;
• generating one or more transaction data blocks for the data file management blockchain, each transaction data block including a modification to the data file;
• signing each of the one or more transaction data blocks to commit each of the one or more transaction data blocks to the data file management blockchain;
• receiving a request to edit the data file from a first entity, the request to edit including a modification of the data file and an identifier corresponding to the first entity;
• responsive to the request to edit, sending an edit request to a second entity for the data file, the edit request including the identifier corresponding to the first entity;
• receiving a confirmation message from the second entity with a signature;
• and
• signing a transaction data block corresponding to the request to edit with the signature received in the confirmation message.
