摘要: Systems and methods are disclosed for securely communicating sensitive such as an identifier. A user device may receive a first message comprising a terminal type indicator. For certain values of the terminal type indicator, the user device may be configured to transmit a request message comprising a first identifier and an encrypted identifier. For other values of the terminal type indicator, the user device may be configured to generating an obfuscated identifier based at least in part on a first portion of a second identifier and a second portion of the encrypted identifier. The user device may then transmit a request message that includes the obfuscated identifier and the encrypted identifier.

摘要: Systems and methods for threshold authenticated encryption are provided. A collection of cryptographic devices may encrypt or decrypt a message, provided that a threshold number of those devices participate in the encryption process. One cryptographic device may generate a commitment message and transmit it to the other selected devices. Those devices may each perform a partial computation using the commitment message, and transmit the partial computations back to the encrypting or decrypting device. The encrypting or decrypting device may use those partial computations to produce a cryptographic key, which may then be used to encrypt or decrypt the message.

摘要: Described herein are a system and techniques for detecting whether biometric data provided in an access request is genuine or a replay. In some embodiments, the system uses an machine learning model trained using genuine and replay sample data which is optimized in order to produce a result set in which results for the genuine samples are pulled closer to a genuine center and results for the replay samples are pushed away from the genuine center. Subjecting input biometric data (e.g., an audio sample) to the trained model results in a classification of the input biometric data as genuine or replay, which can then be used to determine whether or not to verify the input biometric data.

摘要: Systems and methods provide dynamic application selection based on contextual data of a transaction. A portable device may include multiple applications with which a transaction may be processed. These applications may be associated with a variety of priorities. The portable device may provide a list of these applications to an access device from which one application may be selected.

摘要: Provided is a method for training distributed machine learning models. The method may include initializing a distributed machine learning model on a plurality of computing devices. Training data associated with a plurality of samples may be received. Each sample may be forward propagated through the distributed machine learning model to generate an output. A loss for each sample of the plurality of samples may be determined based on the output. The loss for each sample may be backward propagated to each computing device. The parameter(s) of each computational node may be asynchronously updated based on the loss as it is backward propagated and/or while at least one of the samples is forward propagating. The parameter(s) may be stored and/or communicated to the other computing devices. Each of the other computing devices of the plurality of computing devices may store the parameter(s). A system and computer program product are also disclosed.

摘要: A method for verifying that event can take place before the event is executed is disclosed. A verification system is incorporated into an event processing network, such that the verification system can identify newly proposed events and determine whether they can be completed. The verification system can inform the network about verification results through distributed blockchain records. Other changes in event status can also be communicated through and stored in blockchain records.

摘要: Embodiments of the invention are directed to systems and methods for utilizing a multi-tiered caching architecture in a multi-tenant caching system. A portion of the in-memory cache may be allocated as dedicated shares (e.g., dedicated allocations) that are each dedicated to a particular tenant, while another portion of the in-memory cache (e.g., a shared allocation) can be shared by all tenants in the system. When a threshold period of time has elapsed since data stored in a dedicated allocation has last been accessed, the data may be migrated to the shared allocation. If data is accessed from the shared allocation, it may be migrated back to the dedicated allocation Utilizing the techniques for providing a multi-tiered approach to a multi-tenant caching system can increase performance and decrease latency with respect to conventional caching systems.

摘要: A network topology is provided that includes multiple data centers for building blockchain blocks. The data centers can process different subgroups of blocks, and then send updates to one another with information about new blocks. Additionally, some data centers may protect sensitive block body information, and instead may only share block headers.

摘要: A method is disclosed. A computer may receive a request message from an access device. The computer may search a supplemental database for updated supplemental data corresponding to a real credential. The supplemental database may store the real credential, supplemental data, and the updated supplemental data. The updated supplemental data may be provided to the supplemental database in connection with authorization processing involving the real credential. The computer may receive the updated supplemental data associated with the real credential. The computer may transmit a response message to the access device including the updated supplemental data. The request message may be, as examples, an authorization request message comprising a token or a token request message comprising a token.
