Systems and methods for securely using blockchains

Glossary

Blockchain: A distributed ledger technology that maintains a continuous chain of records called blocks. Each block is time-stamped and linked to previous blocks using cryptography to verify all records.

Private Key: A secret digital signature used to authorize blockchain transactions, known only to the owner.

Public Key: A key paired with a private key that can be used to verify the private key's signature.

Wallet: A software application that stores a user's private keys and allows the user to manage their cryptocurrency and digital assets.

Identity as a Service (IDaaS): A cloud-based authentication service that provides real-time, multi-factor, malware-resistant, contextually strong authentication.

Smart Contract: A computer protocol designed to digitally facilitate, verify, or enforce the negotiation or performance of a contract.

Decentralized Application (DApp): An application that runs on a distributed network such as a blockchain.

Anonymous Blockchain: A blockchain in which the identities of the participants are hidden from the public.

Identifiable Blockchain: A blockchain in which the identities of participants are known and can be verified.

Transaction Ledger: A ledger that records all transactions on a blockchain network.

Contract Ledger: A ledger that stores and tracks smart contracts on a blockchain network.

Seed Phrase: A set of words used to generate a deterministic wallet that allows users to backup and restore their wallets.

Short Answer Questions

Please explain the main problem that Talmor et al.'s patent attempts to solve.

Talmor et al.'s patent aims to address security and privacy issues that exist in existing blockchain applications, particularly challenges related to user identity and private key security.

The patent attempts to combine the user authentication capabilities of private chains while retaining the privacy of public chains to achieve more secure and regulated blockchain applications.

Describe two flaws of existing cryptocurrency exchanges.

Lack of trusted third parties: Existing cryptocurrency exchanges lack trusted third parties to arbitrate disputes, making it difficult for users to recover losses.

Anonymity issues: The anonymity of transactions facilitates illegal activities, raising concerns among regulators.

How does Talmor et al.'s patent solve security vulnerabilities related to blockchain private keys?

The patent solves the private key security problem by combining the generation and storage of private keys with the IDaaS service.

The user's private key is no longer stored separately in the wallet, but is dynamically generated by IDaaS and encrypted in combination with the identity string and user input, which effectively improves security.

In Talmor et al.'s patent, what role does IDaaS play in protecting blockchain transactions?

IDaaS provides real-time multi-factor authentication to ensure that only authorized users can perform transactions.

IDaaS is also used to verify the identity of the transaction recipient to prevent malware attacks and fraud.

Explain how Talmor et al.'s patent can be used in the field of trade finance.

The patent can create a secure and traceable transaction platform for trade finance.

Both parties to the transaction can be authenticated through an identifiable blockchain, while the transaction details are recorded on an anonymous blockchain to ensure privacy and security.

How does Talmor et al.'s patent solve the scalability problem of blockchain applications?

The patent solves the scalability problem by storing transaction and contract records in different ledgers.

This separation can increase transaction processing speed and reduce the load on a single blockchain network.

How does Talmor et al.'s patent apply to identity management?

The patent allows a user's identity information to be securely stored and managed using a blockchain.

Users can control access to their identity attributes through wallets and IDaaS and selectively disclose information to third parties.

Describe how Talmor et al.'s patent can be used to create a secure online voting system.

The patent can create a tamper-proof voting system where ballots are signed with the user's private key and stored on an anonymous blockchain.

IDaaS is used to verify the identity of the voter and ensure that each user has only one vote.

How does Talmor et al.'s patent improve existing identity and access management (IAM) systems?

The patent can improve existing systems by providing a more flexible and decentralized IAM solution.

Users can use wallets and IDaaS to manage access to enterprise resources without relying on a central authority.

What functions does the wallet application in Talmor et al.'s patent have?

The wallet application allows users to generate and manage private keys, sign transactions, interact with IDaaS, and access different blockchain applications.

The patent also describes how the wallet application can be used for specific use cases such as identity management, online voting, and trade finance.
