The purpose of the present invention is to provide a new data utilization system in which, while an individual independently uses and utilizes one's own personal data, security and anonymity of the data can be effected. An information processing device used by an individual comprises: a function of transmitting, over a network, data relating to an address on a blockchain network used by the individual to a provider-side information processing device comprising a storage device that is a provision source of data associated with information about the individual; a function of referring to access data (ACT) that includes the data relating to the blockchain network address and data for identifying the provision source of the data and that is issued by the provision-side information processing device for the blockchain network address; and a function of, on the basis of the access data (ACT), acquiring the data associated with the information about the individual from the provider-side storage device and storing said data at least in a storage device or a memory of said individual.

A method may include obtaining various votes for a blockchain transaction from various blockchain nodes. The method may further include determining various weighted votes using the votes and respective cybersecurity states of the blockchain nodes. The respective cybersecurity states may correspond to whether a predetermined security vulnerability is associated with the blockchain nodes. The respective cybersecurity states may be dynamic values that are updated based on changes among predetermined security vulnerabilities. The method may further include determining whether to validate the blockchain transaction based on the weighted votes.

Methods, computer program products, and systems are presented. The methods include, for instance: ascertaining a user state of a user based on user state data for a cognitive menu selection service from an eatery by use of an electronic menu system. Selection criteria to request one or more items from menus of the eatery is determined based on the user state. A request including the selection criteria is sent and the one or more items corresponding to the selection criteria is obtained and presented to the user by use of a customized virtual reality interface on a personal device of the user.

Embodiments facilitate interoperability and secure patient selection for clinical trials and drug/device deployments. An entity may obtain a first set of health parameters and collective demographic information associated with one or more population segments and receive Electronic Health Record (EHR) sub-blocks with patient profile information and corresponding patient medical histories for patients. The entity may determine a subset of eligible candidate patients for a treatment based on information in the EHR sub-blocks and eligibility criteria for the treatment, which may be based the first set of health parameters, and/or the collective demographic information. The entity may transmit sub-blocks comprising eligible candidate patient profiles and medical information associated with the at least one treatment, and, in response to a received transaction block with a transaction confirmation, the entity may augment a multi-dimensional blockchain by linking: the transaction block, with a drug device information block and an EHR block.

Some embodiments are directed to a system (100) for selectively disclosing attributes of a record. An issuer device (110) generates a digital signature on a message comprising the attributes and a secret record identifier. The record, secret record identifier, and signatures are provided to a selector device. The selector device (111) selectively discloses attributes of the record to a receiver device (112), proving authenticity by means of a zero-knowledge proof of knowledge of the signature on the attributes. The receiver device (112) verifies the proof with respect to the public key of the issuer and the received attributes.

A medical pump includes a cuboid pump housing and a front lid that is pivotably hinged to the pump housing. The front lid includes a display, in particular a touch display, and/or operating elements. The front lid is attached to the pump housing with at least one first hinge element and at least one second hinge element. The at least one first hinge element and/or the at least one second hinge element includes or forms at least one electrical connection between the pump housing and the front lid for electrical linking and exchange of data.

A system and method for homomorphic encryption in a healthcare network environment is provided and includes receiving digital data over the healthcare network at a data custodian server in a plurality of formats from various data sources, encrypting the data according to a homomorphic encryption scheme, receiving a query at the data custodian server from a data consumer device concerning a portion of the encrypted data, initiating a secure homomorphic work session between the data custodian server and the data consumer device, generating a homomorphic work space associated with the homomorphic work session, compiling, by the data custodian server, a results set satisfying the query, loading the results set into the homomorphic work space, and building an application programming interface (API) compatible with the results set, the API facilitating encrypted analysis on the results set in the homomorphic work space.

In one exemplary mode, a method to authenticate a user includes connecting to a mobile storage device, which stores an expiration value and a digital signature of login details, the login details comprising at least a username and the expiration value, receiving the digital signature and the expiration value from the mobile storage device, receiving a user input of a personal identification code, verifying the digital signature responsively to the expiration value and the username to authenticate the expiration value and the username, checking that the expiration value has not expired, and providing access to a computing resource logged in under the username responsively to the expiration value and the username being authenticated, the expiration value having not expired, and the personal identification code.

Systems and methods for tracking patient medical records using a medical implant are described herein. The medical implant can comprise a physical structure configured to secure the medical implant within a body of a patient, a proximity communication component physically coupled to the physical structure, and a memory operatively coupled to the proximity communication component. The memory can store a private key, wherein the memory is configured to provide the private key through the proximity communication component to an external device for enabling the external device to access one or more electronic medical records associated with a patient that is implanted with the implant from a distributed blockchain ledger of electronic medical records.

A drug-disease interaction detection server determines a presence or absence of contraindications or relevant precautionary conditions for a treatment for a patient by parsing database(s) based on the treatment, determines values of factors corresponding to the patient based on a real-time analysis of data obtained from an EMR system, generates a total score by computing a total sum of at least a subset of the values of factors, determines whether the total score is greater than or less than or equal to a predetermined threshold, generates a recommendation for prescribing the treatment requested for the patient in response to the determination of the total score and an indication being treated in the patient, determines an availability or unavailability of one or more alternative treatments, generates an additional recommendation for the patient, and receives an order for a selected treatment for the patient based on the additional recommendation.
