ELECTRONIC VOTING PLATFORM AND METHOD THEREOF

Resumen de: EP4632702A1

The present invention concerns the topic of electronic voting; that is, a voting method in which each voter can express his vote, even remotely, via an IT platform. This is a topic in which the interest is due to the fact that many electoral consultations represent quite complex events, because they mobilize a large number of people and must offer very high standards of security; consequently, they are significantly costly events.Electronic voting represents a way to reduce the costs of electoral consultations, to make them more efficient, and therefore also an instrument that can potentially be used more frequently. Moreover, an electoral consultation can be seen as a particular case of information management (a rather complex case, moreover) which, as such, should represent an almost natural, albeit challenging, field of application for information technologies.The proposed solution involves using at least a pair of servers configured to manage the voters and their votes separately, so as to allow, through an "Anonymous Kerberos" type approach, both the certain and reliable identification of the voters and the the anonymity of their vote: the latter is an essential guarantee to protect the freedom of voting.The voting platform indicated in the invention is configured to support a series of IT services combined in an original and complex way. In particular, the main state-of-the-art information technologies used by the invention concern encryption services as well as service

COMPUTER-IMPLEMENTED METHODS AND SYSTEMS FOR SECURE DIGITAL ASSET TOKENIZATION AND TRANSFER USING DISTRIBUTED LEDGER TECHNOLOGY

Resumen de: US2025315894A1

A method for creating and exchanging tokenized assets combines a dual ownership structure with a tiered exchange system. The method involves issuing membership non-fungible tokens to cooperative members, creating a tokenized asset through a legal entity and property ownership non-fungible token, and implementing a smart contract to generate property tokens representing fractional ownership. The exchange system for these property tokens implements sequential buying windows, providing initial exclusive access to non-token holders, followed by access to regional cooperative members, then global cooperative members, and finally institutional buyers. This approach may promote progressive decentralization of ownership while maintaining secure blockchain-based transfers within the cooperative framework. The method may enable fractional ownership of various assets, automated distribution of benefits, and a controlled secondary market structure that balances liquidity provision with ownership diversification.

SYSTEMS AND METHODS TO ENSURE ASSET AND SUPPLY CHAIN INTEGRITY

Resumen de: EP4621681A2

A system for tracking and recording the chain-of-custody for assets within a supply chain that creates a non-repudiatableelectronic log of each custody transfer at each transfer point from initial creation, to final transfer or disposal. In oneembodiment, the system uses encryption technology to register assets that are to be transferred and whose chain ofcustody is to be ensured. Through use of encryption key pairs and blockchain encryption technology, an electronicdocument is created in an encrypted transaction log updated at each change of custody point. At each such change ofcustody point, the new custodians who receive the product are provided with the information generated by the originator.By way of one example, because the system tracks all inputs and outputs to the system at each change of custody point,any alteration in product quantities are immediately identified, and a chain-of-custody integrity problem is identified.
