Abstract: Methods and systems are described herein for enabling users to access user data of other users using cryptographic tokens. A data access system may be used to enable access. The system may receive a blockchain operation request for enabling access to first user data associated with a first user. The system may generate a cryptographic token and an access entry. When the system receives a second blockchain operation request for accessing the first user data, the system may determine one or more parameters for accessing the first user data. In response to verifying the one or more parameters, the data access system may enable access to the first user data.

Abstract: A system can include, for example, a secure data module(s) configured to store sensitive data regarding the user(s), a synthetic dataset generating module(s) configured to generate the synthetic dataset based on the sensitive data, and a control module configured to receive a request from an application for a dataset related to the user(s), provide the request to the synthetic dataset generating module(s), receive the synthetic dataset from the synthetic dataset generating module(s), and provide the synthetic dataset to the application. The synthetic dataset generating module(s) can be configured to generate the synthetic dataset based on the dataset.

Abstract: In some implementations, a mobile device may store information related to a mobile ID registered to the mobile device, wherein the mobile ID is an electronic identity document associated with a user of the mobile device. The mobile device may configure, for the mobile ID, a mobile ID association tree that defines one or more groups that each include, as members, the user of the mobile device and one or more additional users that are each associated with a respective mobile ID, wherein the one or more groups are each associated with one or more shared services that are accessible to each member of a corresponding group based on information related to the mobile ID associated with the respective member.

Abstract: The exemplary embodiments may provide a password-less user authentication mechanism that enables users to be authenticated for accessing an online service. The online service may be, for example, a website that provides a service. A user registers with the online service and then is given a private cryptographic key that is used to gain access to the online service. The exemplary embodiments enable the creation of subaccounts that are affiliated with an account. At least one offspring cryptographic key pair for user authentication may be generated for each subaccount. The offspring cryptographic key pairs are derived from the primary cryptographic key pair for user authentication that is associated with the account. The offspring key cryptographic key pairs are used to gain access to the online service via a subaccount. Each subaccount may have different modes of access. Each subaccount may have different authorizations relative to use of the online service.

Abstract: Embodiments relate to content presentation and filtering preferences of viewers tied to blockchain technology for improved use and applicability in multiple channels. For example, a blockchain platform is described via which content preferences stored on non-fungible tokens tied to user identities are provided to content presenters. In one embodiment, the platform receives a request indicating an on-chain address for a user non-fungible token. With the on-chain address, the platform queries an on-chain program stored on the blockchain to obtain content preferences stored on the user non-fungible token. After providing the content preferences to a content presenter, the platform monitors a content session between the presenter and the user, for example, by collecting data from the user during the session.

Abstract: Systems and methods for providing metadata-based anomaly detection, comprising: storing a plurality of sets of electronic documents associated with a plurality of users; generating a set of metadata items for each document in each set of the plurality of sets of documents; determining a set of features based on the set of metadata items for each document in each set of the plurality of sets of documents; transforming the set of features into a set of feature vectors, each feature vector tagged to indicate a correspondence to a particular anomaly or not; and training, based at least in part on the set of features vectors, a data anomaly-detection machine learning model to obtain a trained data anomaly-detection machine learning model, the data anomaly-detection machine learning model comprising a set of triggering rules that are configured to determine a plurality of anomalies within a particular set of metadata items.

Abstract: Methods and systems disclosed herein may communicate information, such as alerts and notifications, to a cardholder via a color-changing transaction card. In particular, the cardholder may configure one or more thresholds that establish when a transaction card may change colors. For instance, a transaction card may change colors at, or while approaching, a first threshold. The transaction card may change colors at, or while approaching, a second threshold. When the cardholder's balance goes below the thresholds, the transaction card may revert back to the lower threshold color or the original color of the transaction card. Using the techniques described herein a financial institution may convey information to a cardholder in a way that does not require the cardholder to digitally engage with the financial institution.
