Abstract: Methods and systems for the use of multi-party computation (“MPC”) key systems that involve the use of multiple parties, each of which hold respective private data that may be used to evaluate a computation without ever revealing any of the private data held by each party to perform blockchain operations. Using the MPC key systems, the methods and systems generate secure, encrypted communications across distributed computer networks for authorizing use of cryptography-based digital repositories in order to perform blockchain operations in decentralized applications.

Behavioral biometric data may be extracted from the responses and may be used to determine a likelihood the individual is an authorized user of the account.

Abstract: An electronic data protection (EDP) computing device for protecting sensitive data of a user during a computer interaction between the user and a business entity computing device associated with a business entity is provided. The EDP computing device is configured to receive interaction data for the computer interaction from the business entity computing device. The interaction data includes an interaction identifier, a business entity identifier, and a user identifier in lieu of a protected data object. The EDP computing device generates a token request message using the interaction data and a request token and transmits the token request message to the user computing device, prompting the user to pick a user account. The EDP computing device receives a response token identifying an account selected to complete the computer interaction, retrieves the protected data object, and completes the computer interaction using the protected data object.

Abstract: A server computing device receives authentication request messages formatted according to a first message format from a party via a computing device of a user involved in a transaction, translates the messages into modified authentication request messages formatted according to a second message format, and transmits the modified authentication request messages to an authorization computer. The server computing device may augment the modified authentication request messages by including data gathered from the received authentication request messages describing the user, user's computing device, and/or network path between the server computing device and user's computing device, as well as risk scores generated based upon the received authentication request message.

Abstract: Systems and methods for blockchain-based asset authentication are described. The disclosed embodiments leverage the traceability and immutability of blockchains (or distributed ledgers, in general) to enable the authentication and ownership of assets, e.g., luxury goods. In an example, this is achieved by first pairing an authentication chip with a physical product, and writing a transaction correlated with the first pairing to a blockchain. The product being acquired (reacquired) results in the blockchain being updated (e.g., an updated transaction being written to the blockchain) and the (subsequent) owner being provided with a digital passport that can be added to the owner's digital Web3 wallet. The described embodiments advantageously enable digital identities to be associated with physical goods, which adds value for customers making a long-term investment in a luxury good, and promotes sustainability and transparency in manufacturing and retail processes.

Abstract: Various embodiments herein each include at least one of systems, methods, and software for biometric authentication of pre-staged self-service terminal transactions. One embodiment in the form of a method includes connecting, wirelessly via a wireless communication device of a mobile device, to a Self-Service Terminal (SST), such as an ATM or self-service checkout terminal. The mobile device then receives, via the wireless communication device from the SST, biometric authentication data to authenticate an account holder. The received biometric data is then compared on the mobile device with biometric data stored on or read by a biometric reader of the mobile device. When the comparing identifies a match between the received biometric data and the biometric data read by or stored on the mobile device, the method then transmits an authentication message via the wireless communication device to the SST indicating the match.

Abstract: Described is a secure WiFi sharing system for use between neighbors or others in like proximity. The system may include a WiFi signal with an established network connection and a user computing device seeking to access the network connection through the WiFi signal.
