Secure one-time biometrie tokens for non-repudiable multi-party transactions

Abstract: Numerous applications require users to interact with a multitude of entities in order to avail a service. In such applications, the identity of the user is typically verified through physical or digital tokens, which are prone to both identity theft (lost or stolen tokens) and repudiation claims by malicious users. The use of biometrics can provide non-repudiability by ensuring that a purchaser is the bonafide user of the service. However, in applications entailing multiple stakeholders, there may be privacy issues with sharing user's biometrics data. While this concern can be addressed by storing the user's biometric data on the token itself, strong mechanisms are required to ensure that token is both secure and tamper-proof. In this paper, we propose a single use biometric token that relies on Shamir's secret sharing algorithm and blockchain technology to ensure that the encrypted biometric template contained in the token is secure, tamper-proof, and any attempt to use the issued token is irrefutably logged to prove subsequently that the user indeed availed the service. We also analyze issues related to the system security, user privacy, and usability of the proposed solution.

Controlling access to electronic resources based on a user's sociometric identification document

Abstract: A method establishes a session between a network resource and a user device used by a user having a particular sociometric identity. One or more processors identify an interaction between a user and one or more provider entities. The processor(s) identify profiles for the one or more provider entities, and compute a sociometric identity of the user based on the profiles of the one or more provider entities with which the user has had an interaction. One or more processors transmit the sociometric identity to a network resource in order to establish a session between the network resource and a user device used by the user having the sociometric identity.

Automatic identification of food substance

Abstract: A method of displaying information relating to an allergen present in a food substance together with a user profile, the method including capturing an image of a scene, segmenting the image to determining at least a segmentation of the food substance in the image, determining a classification of the food substance using the segmentation, determining a presence of the allergen in the food substance using the classification of the food substance and a database of allergens and food substances, determining a risk to a user using the user profile specifying a user sensitivity to the allergen, and displaying an output including a view of the user profile and the image, wherein the image is augmented to identify the presence of the allergen.

Medication scheduling and alerts

Abstract: Embodiments include method, systems and computer program products for providing medication-related feedback. Aspects include receiving medication information for a patient. Aspects also include receiving a biological, behavioral, or environmental output from a sensor. Aspects also include determining, based upon the biological, behavioral, or environmental output and the medication information for the patient, whether a medication dose is needed. Aspects also include, based on a determination that the medication dose is needed, generating an alert.
