Systems, computer program products, and methods are described herein for an authentication framework for real-time document processing. The present invention is configured to receive, via an image capturing device associated with a point-of-sale system of a merchant, a digital image of a payment instrument; extract, using optical character recognition, payment instrument data from the payment instrument; receive one or more authentication credentials from the user to endorse the payment instrument; determine an authentication level of the user based on at least receiving the one or more authentication credentials from the user; determine whether the authentication level of the user meets an authentication requirement level associated with the processing of the payment instrument; and process, in real-time, the payment instrument.

A system and method for settling monetary and quota-allocated dual currency transactions may be used to reduce Co2 emissions. Each purchasable item (product or service) in the system may have a monetary price and a Carbon price whose value corresponds to a number of Kg of Co2 emitted by the manufacture/sale/use of the purchasable item. The system and method individualizes the reduction of Co2 emissions and allows each consumer to choose purchasable items in part based on the Carbon price.

A system for managing a financial account in a low cash mode. The system may include a memory storing instructions, and a processor configured to execute the instructions to perform operations. The operations may include providing an interface; providing a notification to a user when a balance in the first account is deemed to be in low cash mode; presenting, when the first account balance is deemed to be in low cash mode, an option for a transfer request; receiving, a selection of the option for the transfer request to connect the first account with a second account; transferring funds from the second account to the first account; notifying the user that funds have been transferred from the second account to the first account; and further notifying the user that the balance in the first account is greater than the threshold value.

A method for recharging a live streaming account, a terminal, and a storage medium are provided. The method may include: receiving a recharging request sent by a first user, in which the recharging request includes a user identifier and a recharging amount; determining, according to the user identifier, a credit limit corresponding to the first user currently; judging whether the recharging amount is within a range corresponding to the credit limit; when the recharging amount is within the range corresponding to the credit limit, recharging, according to the recharging amount, an account corresponding to the user identifier.

A method includes: a supervisor writes a digital certificate and a corresponding first public key into an intelligent contract of a blockchain corresponding to an asset type to be supervised, so that all institutions with asset accounts under the asset type can obtain the first public key of the supervisor through the digital certificate, so as to generate an additive homomorphic key for homomorphic encryption of the balance of an asset account; when checking the balance of a new account of a transactor, the supervisor obtains a public key in a public-private key pair corresponding to the new account, generates an additive homomorphic key based on a supervision private key corresponding to the supervisor and a predetermined key exchange protocol and the public key in the public-private key pair according to the key exchange protocol, and decrypts the encrypted balance of the new account, using the generated additive homomorphic key.

According to an example aspect of the present invention, there is provided an apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to compile a set of transactions in a block chain based resource management system that have taken place after the most recent block was established, establish a new block in the block chain, and in establishing the new block, for transactions associated with verification accept messages and lacking sufficient resources, cause transferring of the lacking resources from verification nodes having sent the verification accept messages.

A proof of wallet approach is used for transaction validation for a digital currency. When a transaction is requested, a set of witness nodes are selected to form an ad hoc neural network. The witness nodes may be client devices of other users of the digital currency. Each witness node receives input information about the transaction (e.g., an encrypted amount and nonce) and neural network parameters (e.g., input weights and a bias). The input information passes through the ad hoc neural network, which generates an output validation value. The transaction is approved if the output validation value is consistent with a verification value generated from the transaction parameters, neural network parameters, and digital currency information stored on a blockchain. If the transaction is approved, the transaction is added to the blockchain in conjunction with the identity of the witness nodes and any other pertinent information

An information processing method to be carried out by a terminal may be provided. The information processing method may include: obtaining a payment request; receiving payment processing information from a server to process a payment based on the payment request; and adjusting a payment setting regarding at least one of an amount of money to be used for the payment, and a user authentication for the payment, based on a communication state of the terminal.
