Transaction-enabled methods for providing provable access to a distributed ledger with a tokenized instruction set for polymer production processes are described. A method may include accessing a distributed ledger comprising an instruction set for a polymer production process and tokenizing the instruction set. The method may further include interpreting an instruction set access request and providing provable access to the instruction set. The method may further include providing commands to a production tool of the polymer production process and recording the transaction on the distributed ledger.

A computer-implemented method including, submitting a payment transaction through a network to a merchant website; receiving the payment transaction by a widget program on the merchant website; submitting, a payment transaction request through the network to a backend application; receiving, the payment transaction request; issuing and submitting a transaction identification number through the network to the widget program; creating a matrix barcode from the transaction identification number; scanning the matrix barcode using a mobile computing device; activating a mobile application to receive payment and receiving payment data from a payment card having a card microchip communicating with an EMV library non-embedded in the mobile application; encrypting the payment data and sending the payment data to the backend application; the backend application submitting the payment data to a payment service provider; receiving the payment transaction results; and notifying the widget program and the mobile application of the payment transaction results.

Verified transactions through integrations of social network and payment service computing platforms are described. A payment service computing platform may retrieve one or more profiles of users having a relationship with a first user based on a request received from the first user in the context of a payment transaction with a second user. The payment service computing platform may further determine, based on the one or more profiles, an indirect relationship between the first user and the second user, determine, based at least in part on the determination of the indirect relationship, a trust signal associated with the second user, and cause a user interface to be displayed via a payment application executing on an electronic device associated with the first user, wherein the user interface comprises an indication of an identity of the second user and an indication of the trust signal.

Systems and methods for secure and decentralized payment for digital media content via certificates with wallet information include, responsive to a request for a certificate from a user, obtaining information from the user including identify related information and a wallet address; validating the identify related information; validating the wallet address; and responsive to validating the user and validating the wallet address, creating the certificate including the validated identify related information and the validated wallet address. The certificate can be an X509 certificate.

Systems and methods for authentication may include an authentication server. The authentication server may include a processor and a memory. The processor may be configured to receive a cryptogram associated with a first near field communication data exchange format (NDEF) read. The processor may be configured to perform a first factor authentication of the cryptogram. The processor may be configured to receive a first data set, wherein the first data set is associated with a second NDEF read. The processor may be configured to extract metadata from the first data set. The processor may be configured to perform, after the first factor authentication, a second factor authentication based on the metadata. The processor may be configured to generate a message indicative of an outcome of the second factor authentication. The processor may be configured to transmit the message that instructs the processor to effectuate one or more actions.

An access control system for electric vehicle charging is provided that includes an access device, a secure reservation interface, a reservation server and a smartphone application installed on the smartphone. The access device includes a short-range wireless communication module connected to a processor having control of an electric vehicle charger. The secure reservation interface receives a reservation request for a reservation at a given destination. The reservation server receives the reservation request for the destination, issues a reservation certificate, and transmits the reservation certificate from the reservation server to a smartphone. The smartphone application has access to a short range wireless communication setting corresponding to the access device. The access device receives the reservation certificate from the smartphone application based on use by the smartphone application of the short-range wireless communication setting. The processor activates the electric vehicle charger based on at least the receipt of the reservation certificate.

A first biometric sample of a user is received by an access device from a user device. First biometric information is generated in an obscured format, based on the first biometric sample. A plurality of biometric information is received in an obscured format. The plurality of biometric information corresponds to a plurality of users, and was obtained from biometric samples of the plurality of users. The first biometric information in the obscured format is compared to the plurality of biometric information in the obscured format, and a match result is generated based on the comparing. The match result is provided to a server computer. Based on the match result, information indicating that one of the plurality of users that is associated with one of the plurality of biometric information is the user associated with the first biometric information is received.

The disclosed embodiments provide a distributed transaction system including a group of validator nodes that are known to each other in a network but are indistinguishable to other network nodes. The validator nodes form a Committee including a Leader node and one or more Associate nodes configured to receive and process transaction requests, for example, to add new blocks to one or more blockchains. The Committee may be dynamically changed, such that new network nodes may be added to the Committee or may replace existing validator nodes. The Associate nodes also may coordinate with each other to select a new Leader node. The disclosed embodiments reduce the distributed system's reliance on the stability of any particular node(s) in the network, as the validator nodes in the Committee may be changed at a sufficient frequency to remove unreliable, unavailable, or otherwise untrusted nodes. Further, the disclosed embodiments provide a scheme that helps ensure the Leader node, as well as the other Committee members, functions properly.

A technical validation mechanism is described that includes the use of facial feature recognition and tokenization technology operating in combination with machine learning models can be used such that specific facial or auditory characteristics of how an originating script is effectuated can be used to train the machine learning models, which can then be used to validate a video or a particular dynamically generated passphrase by comparing overlapping phonemes or phoneme transitions between the originating script and the dynamically generated passphrase.

A method for facilitating payment transactions for offline merchants through a third party service provider includes: receiving, by processing server, a confirmation message for a payment transaction from a computing device including a merchant identifier, consumer identifier, and transaction amount; generating, by the processing server, a notification message including the merchant identifier, consumer identifier, and transaction amount; encrypting, by the processing server, the notification message using a public key of a first cryptographic key pair; transmitting, by the processing server, the encrypted notification message to the computing device; receiving, by an encryption device, the encrypted notification message from the computing device; decrypting, by the encryption device, the encrypted notification message using a private key of the first cryptographic key pair; and displaying, by a display interfaced with the encryption device, a confirmation message including the consumer identifier included in the decrypted notification message.
