Abstract: This application relates to apparatus and methods for identifying fraudulent transactions. A computing device receives return data identifying the return of at least one item. The computing device obtains modified strategy data identifying at least one rule of a modified strategy. The rule may be based on the application of at least one dimensionality reduction algorithm to an initial strategy. The computing device applies the modified strategy to the received return data identifying the return of the at least one item, and determines whether the return of the at least one item is fraudulent based on the application of the modified strategy. The computing device generates fraud data identifying whether the return of the at least one item is fraudulent based on the determination, and may transmit the fraud data to another computing device to indicate whether the return is fraudulent.

Abstract: Embodiments described herein are related to systems and methods for executing randomized event sessions using non-fungible tokens (NFTs). In one aspect, a computer receives token identifiers corresponding to NFTs of a blockchain from one or more client devices. The computer may receive a request to initiate a randomized event session from a session client device. The computer may select a non-fungible token of the NFTs for the randomized event session according to a randomization algorithm configured to randomly identify a token identifier from the token identifiers. The computer may determine, a first award value for the randomized event, based on a value assigned to the non-fungible token, and a second award value based upon a fraction of the first award value. The computer may generate a first award notification indicating the first award value for a first user associated with a first session client device.

Abstract: The invention provides a method and corresponding system for controlling the generation of a blockchain transaction, and/or the recipient of a transaction output. It can also be used to control and record the ownership of an asset represented on the blockchain without the need for a separate registry of ownership. The ownership and transfers thereof can be handled and recorded without the need for knowledge of the parties involved or their identities. According to one embodiment, the method comprises the steps of identifying at least one transaction (Tx) on a blockchain which comprises: an unspent transaction output (UTXO) relating to a tokenised asset associated with an asset controller; and an input which spends an output from a previous transaction that is locked by a redeem script hash.

Abstract: A mechanism for verifying digital information provenance and attestation using blockchain distributed ledger technology which reveals unauthorized tampering with credentialed information. Content modifications are detectable leveraging only local edge validation supported by the normative Bitcoin Core cryptographic libraries or equivalent blockchain implementations. The invention prevents unauthorized access, unregulated copy distribution, and orphaned ownership lacking issuer provenance and attestation. The preferred embodiment provides tamper detectable digital content containers supporting credentialing, remote administration, localized validation, distributed access control, and processing instruction signaling. Intermediary third-party services are not required to verify provenance and issuer attestation. Blockchain integrated cryptographic information containers and administrative transactions immutably record the binding between participating parties (e.g.

Abstract: A method includes a validation computer receiving an authorization request message comprising a user state and a user proof from a user device. The user state comprises first and second user state elements. The user proof comprises first, second, and third user proof elements. The validation computer computes a first verification value by multiplying the first user proof element raised to the power of the second user state element, and the second user proof element raised to the power of the first user state element. The computer computes a second verification value by raising the second user proof element to the power of the second user state element. The computer compares the first verification value to a first accumulated state element of an accumulated state. The compares the second verification value to a second accumulated state element. The validation computer authorizes the authorization request message based on the comparison steps.

Abstract: Embodiments of the present invention provide a system for utilizing one or more decentralized applications to allow entities to interface with a blockchain for the purposes of conducting a resource transfer. Typically, the blockchain is a permissioned blockchain which may be accessed only by the entities involved in the resource transfer. The decentralized applications may communicate with the legacy systems within each entity through an application programming interface (API) such that the data stored on the legacy systems may be governed by the blockchain. This ensures the authenticity of the data stored on the legacy systems while preventing the possibility of disparate versions of data being created over time.
