Abstract: Disclosed are systems and method for machine learning and blockchain-based anti-discrimination validation. The described techniques uses a machine learning model to generate a numerical determination associated with a first person based on an input data set associated with the first person. The numerical determination is further based on a corrective module configured to compensate for prohibited discrimination by the machine learning model. The technique generates a blockchain transaction data structure comprising a state of the machine learning model at the time of generating the numerical determination, a copy of the input data set associated with the person, and an indication of a correction by the machine learning model. The blockchain transaction data structure is recorded or published in a blockchain network.

Abstract: A personalized data backup application logs all user actions performed with the user's electronic files. During operation, all files modified by user actions, such as sending messages, uploading images or videos, taking pictures/videos, posting on social networks or in the chats, activating voice or sensory devices, are detected. These files can be located on user's mobile device or computer system. Then, the user backups reflecting data modified by the user on different devices are used to identify user actions based on the modified user data. The user actions are then used to create and/or train a personal behavior avatar that can act as the user to perform some online or electronic action based on the user heuristic patterns stored into the avatar.

Abstract: The present invention provides a highly scalable system for fault tolerant distributed data file storage over a set of functionally equal network servers linked through a local network with network servers and client computers. Data files are represented as a set of transactional records, each record is disassembled into redundant, functionally identical data pieces with original file reassembly dependent only upon the number of data file pieces and not on the presence or absence of any particular data file piece. Local algorithms generate unique data file identifiers upon file creation and disassembly. Changes to the data file storage system are ranked by creation time and stored as separate records with unique transaction identifiers in addition to unique data file identifiers. A transactional data file record is stored by disassembling the transactional file into pieces placed at the network servers. Low-level transactional files are collected to reassemble the data file contents.
