Systems and methods to set up an operation at a computer system connected with a plurality of computer systems via a computer network using a round trip communication of an identifier of the operation

Abstract: Systems and methods to activate the processing of an allocated resource in operations with a processing system by the use of a round trip communication of the identifier of the resource, in which the resource identifier is communicated from a portal of the processing system to a first website, which passes the resource identifier to a second website during forwarding or redirecting a web browser from the first website to the second website, where the second website provides the resource identifier back to the processing system in communications with the processing system for operations required for the activation of the resource. Upon activation, the resource is processed during a communication session between the first website and the portal (or the processing system).

Authentication system using secure multi-party computation

Abstract: The invention is directed to a system that enables an authentication process that involves secure multi-party computation. The authentication process can be performed between a user device operated by a user and an access device. The user device and the access device may conduct the authentication process such that enrollment information and authentication information input by the user is not transmitted between the devices. Instead, the user device may determine and utilize obfuscated values associated with the authentication information. The user device may also determine an obfuscated authentication function that can be utilized to determine an authentication result without revealing enrollment information and authentication information associated with the user. The user can be authenticated based on the authentication result.

Method, System, and Computer Program Product for Determining Solvency of a Digital Asset Exchange

Abstract: Disclosed is a system, method, and computer program product for determining solvency of a digital asset exchange system. The method includes identifying a plurality of blockchain addresses corresponding to a plurality of users of the digital asset exchange system, generating a first commitment to an amount of digital assets corresponding to the plurality of blockchain addresses, generating a second commitment to a balance of each user of the plurality of users, generating a first component of a zero-knowledge algorithm configured to receive, as input, the first commitment, and to output a value generated based on each public key, generating a second component of the zero-knowledge algorithm configured to receive, as input, the second commitment, and to output a value generated based on each user balance, and determining, with at least one processor, that the digital asset exchange system is solvent based on the zero-knowledge algorithm.

Verification and encryption scheme in data storage

Abstract: Embodiments of the invention enable a distributed ledger system including a network of entities that maintain an electronic ledger that can keep track of information related to events performed by various entities in the network. An operating entity may manage access to the distributed ledger system and may allow certain authorities and users to onboard with the distributed ledger system. A user device may generate a request to include data in the electronic ledger. The user device may generate a cryptogram and send the cryptogram with the request to a reader device, which may initiate a verification process to verify the cryptogram. If the cryptogram is verified, the data from the user device may be sent to one or more authorities so that it can be included in the electronic ledger.

Accounts payable system with user control

Abstract: A method is disclosed. The method includes receiving a payment instruction file. In some cases, the payment instruction file contains a plurality of payment instructions with conditional control data to pay one or more suppliers. The conditional control data controls execution of the payment instructions. The method further includes receiving a plurality of transaction messages corresponding to the plurality of payment instructions, respectively, where each transaction message in the plurality of transaction messages is conducted using one or more payment accounts. If transaction data in a transaction message in the plurality of transaction messages does not satisfy the conditional control data, then the transaction message is declined by a server computer. If transaction data in the transaction message in the plurality of transaction messages does satisfy the conditional control data, then the transaction message is approved by the server computer.
