  • Publication number: 20240097915
    Abstract: The disclosed embodiments include computer-implemented processes that, using a distributed notarized ledger, constrain an ability of multiple parties to simultaneously, or near simultaneously, update or modify elements of reference data maintained within a centralized data store. For example, an apparatus may receive, from a first computing system, a request to modify reference data maintained at a second computing system. The apparatus may approve the first requested modification to the reference data based on a notarization criterion maintained within an element of a notarized distributed ledger, and perform operations that record notarization data characterizing the approved modification within an additional element of the notarized distributed ledger. The apparatus may also transmit the notarization data to the first computing system, and the notarization data causing an application program executed by the first computing system to modify local reference data in accordance with the notarization data.

  • Publication number: 20230418809
    Abstract: The disclosed exemplary embodiments include computer-implemented systems, devices, and processes that securely distribute digital assets within a computing environment using permissioned distributed ledgers. For example, an apparatus may receive, from a computing system, an allocation request, a first digital signature applied to the allocation request, and a second digital signature applied to the allocation request and to the first digital signature. Based on a validation of the first and second digital signatures, the apparatus may approve the allocation request and allocate a digital asset to the first device in accordance with the approved allocation request. The apparatus may also perform operations that record a public key and asset data identifying a digital asset onto a distributed ledger, and may generate and transmit, to the first device, confirmation data indicative of the allocation of the digital asset to the first device.

  • Publication number: 20230177042
    Abstract: An audio stream is detected during a communication session with a user. Natural language processing on the audio stream is performed to update a set of attributes by supplementing the set of attributes based on attributes derived from the audio stream. A set of filter values is updated based on the updated set of attributes. The updated set of filter values is used to query a set of databases to obtain datasets. A probabilistic program is executed during the communication session by determining a set of probability parameters characterizing a probability of an anomaly occurring based on the datasets and the set of attributes. A determination is made if whether the probability satisfies a threshold. In response to a determination that the probability satisfies the threshold, a record is updated to identify the communication session to indicate that the threshold is satisfied.

  • Patent number: 11669833
    Abstract: Quantum security may be enhanced through the use of quantum-safe validators for transactions whereby the quantum-safe validators process quantum-safe addresses and signatures of parties to the transactions. Quantum safety may be added to conventional blockchain transactions, for example, via smart contracts which are executed using cryptographic interlocks to between conventional smart contract execution engines and quantum-safe validators to ensure both quantum-safe processing of addresses and signatures and legitimacy of quantum-safe validators in presenting transactions for incorporation on the chain.

  • Publication number: 20230155810
    Abstract: The disclosed exemplary embodiments include computer-implemented apparatuses and methods that validate confidential data based privacy-preserving homomorphic computations involving encrypted data. For example, an apparatus may receive, from a first computing system, encrypted data that includes a first encrypted value representative of at least one of first account data or an element of cryptographic data. Based on the first encrypted value and on second encrypted values, the apparatus may generate encrypted residual values representative of second account data associated with one or more reference accounts, and the apparatus may request and receive a decrypted residual value associated with each of the encrypted residual values from a second computing system. The apparatus may transmit the decrypted residual values to the first computing system, which may validate the first account data based on at least the decrypted residual values and perform operations associated with the validated first account data.

  • Publication number: 20230006809
    Abstract: The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that perform homomorphic computations on encrypted third-party data within a distributed computing environment. For example, an apparatus receives a homomorphic public key and encrypted transaction data characterizing an exchange of data from a computing system, and encrypts modelling data associated with a first predictive model using the homomorphic public key. The apparatus may perform homomorphic computations that apply the first predictive model to the encrypted transaction data in accordance with the encrypted first modelling data, and transmit an encrypted first output of the homomorphic computations to the computing system, which may decrypt the encrypted first output using a homomorphic private key and generate decrypted output data indicative of a predicted likelihood that the data exchange represents fraudulent activity.

  • Patent number: 11444782
    Abstract: The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that dynamically manage exchanges of data using a cryptographically secure distributed ledger and homomorphic commitments. For example, and in response to an occurrence of a triggering event, an apparatus may obtain parameter values that characterize the data exchange, first commitment values representative of the parameter values, and a first digital signature. In response to a verification of the first digital signature, the apparatus may apply a second digital signature to commitment data that includes the first commitment values and a second commitment value representative of the first digital signature. The apparatus may transmit a signal that includes the commitment data and the second digital signature to a computing system, which generates an element of distributed ledger that includes the commitment data and the second digital signature in response to a verification of the second digital signature.
