Systems and methods for blockchain-based secure storage
Systems and methods for blockchain-based secure storage are disclosed. In one embodiment, in an information processing apparatus comprising at least one computer processor, a method for blockchain-based secure storage may include: (1) receiving a plurality of data files from a data file source; (2) bundling the plurality of data files into a package; (3) generating a first hash for each file name for each of the plurality of data files, and a second hash for contents of each of the plurality of data files; (4) generating a block comprising the first hash, the second hash, and a reference to a prior block; (5) encrypting each of the plurality of data files in the package; (6) sending the plurality of packages to a storage provider; and (7) committing the block to a distributed ledger.
1. A method for blockchain-based secure storage, comprising:
in an information processing apparatus comprising at least one computer processor:
receiving a plurality of data files from a data file source;
bundling the plurality of data files into a package, wherein the data files are bundled in the package based on a type of data in the data files and based on a user associated with the data files;
generating a first hash for each file name for each of the plurality of data files, and a second hash for contents of each of the plurality of data files;
generating a block comprising the first hash, the second hash, and a reference to a prior block;
encrypting each of the plurality of data files in the package;
sending the package to a storage provider;
committing the block to a distributed ledger;
combining metadata for a plurality of packages, including the package, into a capsule wherein the metadata comprises a public key for the capsule, and a notification indication, and wherein the notification indication includes a notification preference of the user associated with the data files;
storing the capsule; and
providing a private key that corresponds to the public key to the user associated with the data files.
2. The method of claim 1 , wherein the data files are bundled based on a source of data in the data files.
3. The method of claim 1 , wherein the data files are bundled based on an application associated with the data files.
4. The method of claim 1 , further comprising:
selecting the storage provider from a plurality of storage providers.
5. The method of claim 1 , wherein the metadata comprises at least one of a capsule ID, a nonce, a hash of the block, a hash of the prior block, and a date and time of capsule creation.
6. The method of claim 1 , wherein the notification indication includes an electronic mail address of the user associated with the data files.
7. The method of claim 1 , wherein the notification indication includes an indication that the user associated with the data files will receive a notification when a new block based on the package is added to the distributed ledger.
8. A system for blockchain-based secure storage, comprising:
a data file source;
a distributed ledger;
a storage provider; and
an information processing apparatus comprising at least one computer processor and executing a computer program;
wherein:
the computer program receives a plurality of data files from the data file source;
the computer program bundles the plurality of data files into a package, and wherein the data files are bundled in the package based on a type of data in the data files and based on a user associated with the data files;
the computer program generates a first hash for each file name for each of the plurality of data files, and a second hash for contents of each of the plurality of data files;
the computer program generates a block comprising the first hash, the second hash, and a reference to a prior block;
the computer program encrypts each of the plurality of data files in the package;
the computer program sends the package to the storage provider;
the computer program commits the block to the distributed ledger;
the computer program combines metadata for a plurality of packages, including the package, into a capsule wherein the metadata comprises a public key for the capsule, and a notification indication, and wherein the notification indication includes a notification preference of the user associated with the data files;
the computer program stores the capsule; and
the computer program provides a private key that corresponds to the public key to the user associated with the data files.
9. The system of claim 8 , wherein the data files are bundled based on a source of data in the data files.
10. The system of claim 8 , wherein the data files are bundled based on an application associated with the data files.
11. The system of claim 8 , wherein the computer program further selects the storage provider from a plurality of storage providers.
12. The system of claim 8 , wherein the metadata comprises at least one of a capsule ID, a nonce, a hash of the block, a hash of the prior block, and a date and time of capsule creation.
13. The system of claim 8 , wherein the notification indication includes an electronic mail address of the user associated with the data files.
14. The system of claim 8 , wherein the notification indication includes an indication that the user associated with the data files will receive a notification when a new block based on the package is added to the distributed ledger.
