This disclosure presents a method and system to securely distribute educational content to residents of controlled-environment facilities participating in voluntary educational programs. The method and system involve the provision of portable devices to residents. The residents view externally managed educational content on the portable devices. Users outside of the controlled-environment facility configure classes and students and tailor curricula for individual residents. A portable device downloads the appropriate educational content through a synchronization process that occurs within the controlled-environment facility by interfacing with a synchronization and charging station. The portable device functions only to access the educational content and does not allow any unrelated capabilities or functionalities.

Method and system disclosed herein facilitate retrieval of a blockchain key. The method comprises receiving a key store comprising a first encryption method, a second encryption method, and identification information of one or more network nodes storing a plurality of encrypted storage keys; displaying an authentication request and receiving and input form the user in response to the authentication request; upon the input received matching a record within a database, instructing the one or more network nodes to transmit the encrypted key segments; decrypting each encrypted key segment based on the first encryption method; and generating a blockchain key by appending the strings of the key segments based on the second encryption method.

Systems and methods for securing user location data are described. A method includes receiving, by a location server computer, an encrypted location from a mobile device. The encrypted location is a location of the mobile device encrypted with a public key. The method then includes receiving, by the location server computer, a location request message from an interaction processing server and partially decrypting, by the location server computer, the encrypted location with a first private key share to form a partially decrypted location. The method further includes transmitting, by the location server computer to the interaction processing server, a location response message with the encrypted location and the partially decrypted location. The interaction processing server then uses the partially decrypted location and the second private key share to form a decrypted location.

A method and system for automatic device provisioning includes a computer system for authenticating a user using a first device. The computer system receives a request for automatic provisioning of a second device. An authentication token and a request identifier of the request is associated with a provisioning data structure for the user. The request including the authentication token is sent to a third device. The computer system receives a unique identifier for the second device from the third device. Based on a determination that the unique identifier and the authentication token of the second device match the unique identifier and authentication token in the provisioning data structure, authenticate the second device, retrieve a configuration profile for the user, and cause application of the configuration profile to one or more settings of the second device.

Methods, systems, and apparatuses are described herein for improving computer authentication processes by generating authentication questions based on the location of a user. Transaction data indicating a plurality of transactions associated with a user account may be received. Location data indicating a plurality of locations of a user device might be received. At least a subset of the plurality of transactions may be tagged, based on the location data, with an indication that a user was present for a respective transaction. For example, a location of a merchant might be compared to a user device location indicated by the location data. A plurality of authentication questions might be generated based on the subset of the plurality of transactions. Access to the user account might be provided based on responses to the plurality of authentication questions.

A data packet generator periodically generates a data packet including a passcode comprising a plurality of characters. The data packet is sent to a server or a computing device for validation. If validated, the data packet is used, for example, to identify the location of a user or device. Additional systems and methods involving such a data packet generator are also disclosed.

A method for predicting one or more events includes generating, for features of each of at least two feature types, an intermediate representation using a representation learning model for the at least two feature types. The intermediate representations of the at least two feature types are analyzed using a neural network and at least one neural network model so as to provide a joint representation for predicting certain events. One or more actions to be taken can be determined based on the one or more events predicted by the joint representation.

Features are described for efficiently and accurately identifying a user of an electronic device with limited user interaction. The features include receiving a mobile device identifier from the mobile device. The features include transmitting the mobile device identifier to a service provider associated with the mobile device. The features include receiving information identifying the user from the service provider. The features include identifying a set of candidates associated with at least a portion of the information. The features include generating a metric for the candidates included in the set of candidates. An individual metric indicates a degree of relatedness between a value for the user for the at least one data field and a value for a candidate for the at least one data field. The features include identifying the user as a specific candidate included in the set of candidates based on the metric corresponding to a threshold.

An individual data unit for enhancing the security of a user data record is provided that includes a processor and a memory configured to store data. The individual data unit is associated with a network and the memory is in communication with the processor. The memory has instructions stored thereon which, when read and executed by the processor cause the individual data unit to perform basic operations only. The basic operations include communicating securely with computing devices, computer systems, and a central user data server. Moreover, the basic operations include receiving a user data record, storing the user data record, retrieving the user data record, and transmitting the user data record. The individual data unit can be located in a geographic location associated with the user which can be different than the geographic locations of the computer systems and the central user data server.

Systems and methods for indexing geological features are disclosed. In one embodiment, a method for indexing geological features includes accessing a database storing a plurality of map objects that originate from documents. Each map object includes a map defined by a geographical boundary and a text caption. The method includes, for each map object, determining a plurality of geohashes within the geographical boundary, and includes, for each map object, comparing terms of the text caption with a list of geological keywords. For each map object, the method includes identifying one or more geological noun phrases within the text caption that match one or more geological noun phrases of the list. The method includes determining, for each geological noun phrase, one or more geohashes associated with the geological noun phrase and, for each geohash, determining a frequency that the geohash is associated with the geological noun phrase.
