Abstract: A secure smart card is described. The smart card can include a processor, a memory and a transceiver. The smart card can communicate with various terminals and store a digital signature and other information on the card. Another terminal can validate the information stored on the smart card using the digital signature. In certain embodiments, the terminal can also validate the information by using a blockchain. The advanced design of the smart card obviates the need for a network connection.

Abstract: Methods and systems are described here for porting accounts to multiple computing platforms. Blockchain technology may be used and in particular cryptographic tokens (e.g., non-fungible tokens) may be used. A cryptographic token may represent a user account and may enable usage of the cryptographic token to provide portability of the user account. An access control system may be used to perform operations described herein. The access control system may receive a request for using, at a computing platform, an account of the user. The request may include an identifier of a cryptographic token. The access control system may determine, based on the cryptographic token, that access to the user account may be permitted and the request may be fulfilled.

Abstract: Methods and systems are described herein for using cryptographic tokens that represent real-world items to enable those items to be used in different virtual worlds (e.g., game worlds). In particular, an object retrieval system may be used to retrieve a cryptographic token that encodes parameter data for an object to be used (e.g., displayed) within a plurality of computing platforms. The object retrieval system may determine (e.g., using a cryptographic signature) that the user is allowed to use the object and may then generate a set of parameters for representing the object with the particular computing platform requesting the object. The object retrieval system may then transmit the parameters to the requesting platform. The object retrieval system may perform the same operations for requests from other platforms, such that the object retrieval system may uniquely encode the parameters for the particular platforms.

Abstract: A contactless card useful for adjusting the operation, configuration, and/or performance of a secondary device is described. The contactless card is equipped with a communication interface which allows the contactless card to transmit information to the secondary device using NFC signals. The contactless card stores accommodation information related to a physical accommodation desired by the user and transmits that information in the form of an accommodation message to the secondary device after being placed in a NFC field generated by the secondary device. In some embodiments, the contactless card requests an authentication certificate in order to determine a degree of trust prior to sending an accommodation message. In some embodiments, the contactless card may adjust what accommodation information is included in the accommodation message based on the authentication certificate received from the secondary device.

Abstract: Systems and methods for recovery access to lost blockchain wallet seed phrases are disclosed. The systems and methods can store seed phrases for users for future retrieval. In some examples, a decentralized oracle creates an oracle private key that can be used to authenticate a user who is requesting the seed phrase. In some examples, the oracle creates a private/public key pair that can be used to transmit and store an encrypted version of the seed phrase. The authentication steps described herein also include knowledge-based authentication questions about the wallet, e.g., prior transactions using the wallet, value of the wallet, and the like.

Abstract: Example embodiments of systems and methods for data transmission between a contactless card and a client device in support of a FIDO authentication are provided. In an embodiment, upon receipt of a challenge issued by a server in connection with a pending transaction, the contactless card may authorize the client device to utilize a FIDO private key to respond to the challenge. If the response to the challenge is successful, the FIDO authentication may proceed and the transaction may be completed.

The receiving device can generate the diversified key based on the master key and can decrypt the data and validate the protected counter value using the diversified key.

Abstract: Systems, methods, apparatuses, and computer-readable media for secure management of accounts on display devices using a contactless card. An application executing on a display device may receive a request specifying a service provider. The display device may receive a cryptogram generated a contactless card, and transmit the cryptogram to an authentication server. The authentication server may decrypt the cryptogram and generate a virtual account number associated with the contactless card. The authentication server may transmit the virtual account number to the service provider, which may create an account based at least in part on the virtual account number and the decryption of the cryptogram by the authentication server. The display may receive an authentication token generated by the service provider for the account, and access the account created by the service provider based at least in part on the authentication token.

Abstract: A position alignment system facilitates positioning of a contactless card in a ‘sweet spot’ in a target volume relative to a contactless card reading device. Alignment logic uses information captured from available imaging devices such as infrared proximity detectors, cameras, infrared sensors, dot projectors, and the like to guide the card to a target location. The captured image information is processed to identify a card position, trajectory and predicted location using one or both of a machine learning model and/or a Simultaneous Localization and Mapping logic. Trajectory adjustment and prompt identification may be intelligently controlled and customized using machine-learning techniques to customize guidance based on the preference and/or historical behavior of the user. As a result, the speed and accuracy of contactless card alignment is improved and received NFC signal strength is maximized, thereby reducing the occurrence of dropped transactions.

Abstract: In some embodiments, generating synthetic training datasets for training machine learning models in training data-sparse environments for non-homogenous predictions may be facilitated. In some embodiments, user-specific information associated with a user may be received. The system may generate synthetic training data representing one or more alternative actions corresponding to one or more characteristics by: labeling the user-specific information, determining (e.g., based on the labeled user-specific information) one or more characteristics of the labeled user-specific information, and determining (e.g., based on the one or more characteristics) one or more alternative actions corresponding to the one or more characteristics. The system may then train a machine learning model based on the synthetic training data to generate a prediction in response to providing an action of a first user to the machine learning model.
