Systems and methods allow for a variety of partners to store information in a database utilizing connected services to securely allow retrieval of such data by the partners. A collection of data points that make up a record allows for positive record matching. Individual data elements are generally stored for each partner connected to the record. Partners can only store data elements associated with a unique, known record. Numerous partners may contribute their data in the form of record components and each retains access rights to their own private data which is not shared within the platform. This allows for different data about the same record and data point to be stored by each party (partner). Partners can retrieve their own values should the need arise and also have access to the sureEcosystem Value for fields where the partner has contributed qualifying data. The sureEcosystem Value comes from an algorithm utilizing value frequency, submission dates, partner rankings, record owner input and other validation components in its analysis of contributed information to determine the value most likely accurate at any given time.

A method for storing a data object includes identifying data segments of the data object. The method continues with generating key indexes for the data segments. For a data segment, the method continues with accessing data segment key information based on a corresponding key index of the plurality of key indexes to determine whether an encryption key has been generated for a similar data segment. When the encryption key has been generated for the similar data segment, the method continues with using the encryption key to encrypt the data segment to produce an encrypted data segment. The method continues with compressing the encrypted data segment to produce a compressed and encrypted data segment. The method continues with storing the compressed and encrypted data segment in a storage unit of a dispersed storage network (DSN).

A method for execution by a dispersed storage and task (DST) processing unit includes obtaining audit records for an audit object and determining when the audit object is complete. When the audit object is complete, aggregating the audit records of the audit object within the audit object by generating the audit object to include the audit records; generating identifier (ID) information and generating integrity information. Fields of the audit object are populated with the audit records, the ID information, and the integrity information and a name of the audit object is determined for storage of the audit object and the name of the audit object in a dispersed storage network (DSN).

A method includes monitoring write processing performance while storing a plurality of sets of encoded data slices in storage units. The method includes comparing the write processing performance with a desire write performance range. When the write processing performance compares unfavorably to the desire write performance range, the method includes establishing a data partition between the data segments of the data encoded using the first dispersed storage error encoding parameters and subsequent data segments of the data; determining second dispersed storage error encoding parameters based on the unfavorable comparison between the write processing performance and the desired write performance range; encoding the subsequent data segments of the data using the second dispersed storage error encoding parameters to produce a second plurality of sets of encoded data slices; and monitoring write processing performance while storing the second plurality of sets of encoded data slices in the storage units.

The technique relates to a method and apparatus for dynamic destruction of data in a remote data storage platform. This involves receiving a first set of data records with random values and then updating the random values associated with the subsets of the first set of data records into actual values through one or more update operations. After sequential steps of updates, a second set of data records with actual values are obtained. After working of this data for a period of time the owner of the data again begins updating the actual values associated with the subset of the second set of data records into random values. When all the data records are updated to random values the owner of the data successfully ends the Service Level Agreement period.

A system for generating a comprehensive individualized electronic health information monetization platform, which will facilitate the management, monitoring, and monetization of an individual's personal health information (PHI). The system generates comprehensive individualized electronic health information monetization platform, and includes a data storage containing user identification information, user electronic health information, user financial information, and one or more user acquisition preferences, a data source generator, and an electronic health information transaction processor. An electronic health information transaction processor may upload the de-identified synthesized data from the data source generator, parse the de-identified synthesized data to build a search index, evaluate the data to generate a data acquisition trending model, generate a comprehensive individualized electronic health information monetization platform utilizing the data acquisition trending model that determines and recommends data samples that are compatible.

The present disclosure provides an electronic signature authentication system and method capable of enhancing stability and reliability of an electronic signature by generating electronic signature information for authentication of an electronic document based on biometric information of a user. The electronic signature authentication system includes an authentication server, a user device, and an electronic document device, and is capable of providing identification of an electronic document provider among the electronic document provider, a signer of the electronic document, and a third party person using a signed electronic document, and providing verifications of integrity of the electronic document, prevention of repudiation of the signer, verification of whether the electronic document signed by the signer is identical to the electronic document provided by the electronic document provider, and a scheme for preventing falsification or tampering of the electronic document committed by the electronic document provider.

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.

A blockchain-based data distribution management method according to an embodiment is performed by a computing device. The method includes generating a plurality of shards by fragmenting a first information, requesting a first block event for distributed storage of the plurality of shards in a plurality of off-chain storages to a blockchain network, and transmitting the plurality of shards to the plurality of off-chain storages, wherein a second information indicating a history of the plurality of shards distributed and stored in the plurality of off-chain storages is recorded in the blockchain network through the first block event, wherein when a predetermined number or more of shards among the plurality of shards are collected, the first information is restored from the collected predetermined number or more of shards.

A computer system that interfaces with a blockchain is provided. The computer system receives match data for a match between a first data transaction request that is associated with a first identifier and a second data transaction request that is associated with a second identifier. A first blockchain transaction is generated based on the match data and stored to a blockchain. At least one further blockchain transaction is generates that splits the match into two different transactions—one between the first identifier and an intermediary and the second between the intermediary. These are recorded to the blockchain via the further blockchain transactions.
