Methods and apparatus provide communications among respiratory therapy device (“TD”), server and intermediary (e.g., a control device (“CTLD”) for the therapy device) to improve security. More secure communication channel(s) may be established using shared secrets derived with different channels. The communications may include transmitting therapy data from TD to server for authentication. The CTLD may receive the data and a nonce from a server. The CTLD receives from the TD a signing key dependent on the nonce and a secret shared by TD and server. The CTLD generates an authorisation code with received therapy data and the key for authentication of the data by the server upon its receipt of the code and data. The server computes (1) a key from the nonce and the secret known to TD, and (2) another authorisation code from received therapy data and the key. Data authentication may involve comparing received and computed codes.

A medical imaging communication system processes medical images for being transmitted to a client device. The system receives a set of images, each image corresponding to a slice of a three-dimensional object. The system combines a first subset of the images into a first combined image and combines a second subset of the images into a second combined image. The first and second combined image are compressed using a lossless compression algorithm and transmitted to the client device.

A process for the segregation, sterilization, and purification of recycled plastic medical waste with the subsequent production of plastic products made therefrom is disclosed. Also disclosed is a method for the front-end segregation of recycled plastic medical waste into a polypropylene waste stream and a mixed plastic waste stream. These segregated streams are further purified through a processing method that removes contaminating fibrous, metal and other waste products. Polypropylene and mixed plastic streams isolated using these methods yield a homogenous material that can be blended with other materials for the production of raw plastic or for extrusion to form commercial plastic products. A method for tracking regulated and non-regulated medical waste stream production kinetics and chain of custody from discrete waste disposal sites is also disclosed.

Methods, systems, and techniques for private identity verification involve obtaining a cryptographically secure commitment that is generated using a first user identifier and a private user identifier associated with the first user identifier; receiving, from an identity verification system, initial zero knowledge proof messages comprising the commitment; sending, to the identity verification system, a set of cryptographically secure known identifier commitments generated using a set of private user identifiers; receiving, from the identity verification system: (i) a zero knowledge proof response generated using the zero knowledge proof challenge; and (ii) proof that the private user identifier used in the initial zero knowledge proof messages comprises part of the set of private user identifiers; and verifying that the private user identifier used in the initial zero knowledge proof messages comprises part of the set of private user identifiers.

A system including one or more memory devices having instructions stored thereon, that, when executed by one or more processors, cause the one or more processors to receive travel data associated with a travel plan of a user indicating one or more travel destinations. The instructions cause the one or more processors to receive destination risk data indicating a destination risk of the one or more travel destinations associated with transmission of an infectious disease, receive personal risk data indicating a risk of the user associated with the infectious disease, and generate an infection travel risk score for the user based on the destination risk data and the personal risk data.

A security platform architecture is described herein. A user identity platform architecture which uses a multitude of biometric analytics to create an identity token unique to an individual human. This token is derived on biometric factors like human behaviors, motion analytics, human physical characteristics like facial patterns, voice recognition prints, usage of device patterns, user location actions and other human behaviors which can derive a token or be used as a dynamic password identifying the unique individual with high calculated confidence. Because of the dynamic nature and the many different factors, this method is extremely difficult to spoof or hack by malicious actors or malware software.

A data monitoring system comprising a server communicatively coupled to a client device and a data module via a network. The server is configured to store a private key of a public-private key pair associated with the data module, receive a request from the client device for authenticated access to the data module, and generate an authentication key based at least on the private key and a time. The client device is configured to generate the request for authenticated access to the data module and transmit the request to the server. The data module is configured to store the private key of the public-private key pair associated with the data module, generate the authentication key based at least on the private key and the time, and grant access to the data module if the authentication key generated by the data module and the authentication key generated by the server match.

DICOM data is automatically prepared for transit outside of the clinical-data infrastructure, by examining a plurality of metadata fields in the corresponding metadata in the DICOM data; identifying a first subset of the metadata fields as containing private information; identifying a second subset of the metadata fields as private-information free; accessing at least some of the plurality of layers of the DICOM data; and transforming the accessed layers into a single transmission-image, the transmission-image being in a format i) other than DICOM and ii) that stores the second subset of the metadata fields as transmission-metadata in a scheme that is non-redundant for a given transmission-image.

A vaccination and immunization system designed to securely track administration of a vaccine for issuance of a related electronically-transmittable universal vaccination certificate for ensuring the safe and secure data collection of individuals being vaccinated and the reliable and trustworthy issuance of their resulting secured universal vaccine certificate.

The present invention provides systems and methods for exchanging health data. A health data exchange platform includes health data from a plurality of data sources. The health data exchange platform preferably utilizes blockchain technology. The health data exchange platform includes both buyers of health data and suppliers of health data. The health data exchange platform includes a phenotype network system including at least one remote server, a user profile database, a report database, a permissions database, a geographic incident database, and a medical community database.
