In one embodiment, a method includes identifying datasets associated with a party and identifying one or more decentralized identifiers (DIDs) associated with the datasets. The method also includes generating an aggregated dataset associated with the DIDs and generating a training dataset associated with the aggregated dataset. The method further includes using one or more machine learning algorithms to recognize patterns within the training dataset.

A system uses information submitted in connection with a request to determine if and how to process the request. The information may be electronically signed by a requestor using a key such that the system processing the request can verify that the requestor has the key and that the information is authentic. The information may include information that identifies a holder of a key needed for processing the request, where the holder of the key can be the system or another, possibly third party, system.

A method comprises receiving a session identifier from a streaming system that identifies a user session with the streaming system. The method further includes receiving a first message from a streaming system that is based on a token that is generated based on a combination of the session identifier and a timestamp at which an insertable content item was presented to the user in a content stream by the streaming system. The first message is decrypted using a plurality of timestamps that are within a range of a current time. An identifier is determined for the insertable content item based on the decrypted message. A second message is transmitted to an enabling system, the message including instructions for execution by the enabling system to execute one or more operations with the identified insertable content item.

A method of generating a hierarchical deterministic keys portfolio, in particular to sign transactions sent to a blockchain. The generation method includes an initialization phase by an administrator and a phase of setting parameters for at least one user. Private key usage contexts are created from the administrator account, each context specifying conditions for use of the private key in said context. User accounts are also created, each user account being associated with a private key in the tree structure, the private key of said user being obtained from a master private key of the administrator, the usage context to which the user account is attached, and the user's identifier.

Systems, methods, articles of manufacture, and computer-readable media. A communications interface may receive an indication that a server preauthorized a transaction. The communications interface may receive, from a point of sale device, an indication to pay for the transaction. The contactless card may determine, based on rules stored in the memory, that the location of the mobile device is within one or more locations the contactless card is permitted for use. The contactless card may generate transaction data comprising: indications of an account number and an expiration date of the contactless card, and the indication of the preauthorization. The contactless card may transmit the transaction data to the POS device as payment for the transaction. The server may authorize payment for the transaction using at least a portion of the transaction data based at least in part on identifying the indication of the preauthorization in the transaction data.

Systems and method are provided for data self-protection. The systems and methods may involve installing a sentry on a computer system, the sentry including a file system filter installed on a kernel of that computer system; providing a central sentry platform in communication with the sentry, operating the central sentry platform to send a data self-protection policy to the sentry, the data self-protection policy being encrypted so that it can only be modified by the central sentry platform; operating the file system filter to control access to encrypted data stored on the computer system, by, for each process making a file access request to the encrypted data, the file system filter receiving and handling that file access request according to the data self-protection policy; and, operating the central sentry platform to monitor the sentry and to receive information from the sentry regarding access to the encrypted data.

Methods, systems, and apparatuses are provided for flight management to configure an aircraft configuration (config) file accessible by the avionic system wherein an avionic service is implemented by a flight management system (FMS) for corroborating allowance of access using one of a set of validation procedures for corroboration prior to execution of a request for content to the config file including validating that a user request for a session is authorized based on user identification data, that a client request by an Electronic Flight Bag (EFB) application for a session is authorized based on client identification data, and in response to the client request, determining that an EFB application request is encrypted and performing a decrypt procedure of the EFB application request based on private key data of a private key; and encrypting an EFB application response based on public key data of a public key from the config file.

Methods and systems for improving the robustness of wireless communications. The methods and systems provided transmit data packets over a first isochronous stream and transmit one or more supplemental data packets over the same time intervals. The one or more supplemental data packets are used to re-create and/or enhance at least a portion of one or more data packets of the plurality of data packets that have already been sent. Alternatively, the one or more supplemental data packets are used to create and/or enhance at least a portion of one or more data packets of the plurality of data packets that will be received during the next isochronous intervals. The methods and system described herein allow for increased robustness by allowing for better retransmission with correctly received packets and the methods set forth herein work with any Bluetooth broadcaster sink without modification.

This disclosure relates to systems and methods for enabling the use of secret digital or electronic information without exposing the sensitive information to unsecured applications. In certain embodiments, the methods may include invoking, by a client application executing in an open processing domain, a secure abstraction layer configured to interface with secret data protected by a secure processing domain. Secure operations may be securely performed on the secret data by the secure abstraction layer in the secure processing domain based on an invocation from a client application running in the open processing domain.

Some embodiments relate to systems and methods for secure information sharing using an information sharing engine. The information sharing engine configured to manage data access keys and data access control configuration, store the data access keys and data access control configuration on a distributed ledger network and selectively retrieve the data access keys from the distributed ledger network based on the data access control configuration.
