Digital currency tracking method based on monero

Abstract

The invention relates to a digital currency tracking method based on monero, and the method comprises the following steps: carrying out initialization on a system, generating system parameters, and generating a secret key for tracking authority; a user generating a transaction order, a payer generating a primary public key for a payee, and embedding into a long-term public key tracking tag; the payer performing mintage for a payment account; the payer pulling in a group of mixed accounts to hide a real payment account; generating a primary public key tracking tag; and completing the transaction order, and signing the transaction order; broadcasting the transaction order to a P2P network; a miner generating a block, collecting the transaction order in the P2P network, verifying the validity of the collected transaction order, using the valid transaction order to mine, generating a new block, and broadcasting the block; a tracking authority tracking a malicious payer, and tracking the primary public key and the long-term public key of the malicious payer when discovering the malicious payer so as to cancel the anonymity of the malicious payer and generate evidences to prove the correctness of the tracking result.

Description

Technical field [0001] The invention belongs to the technical field of network security, and specifically relates to a method for tracking digital currency based on Monero. Background technique [0002] Cryptocurrency is a digital currency based on public key cryptography. Traditional electronic money is based on a trusted third party, while cryptocurrency is decentralized, and both parties to the transaction can directly conduct transactions without going through a third party. The transaction and verification of cryptocurrency are realized through the blockchain, which is a decentralized public ledger that is maintained in a verifiable and permanent manner by all participants in the system. Blockchain is a technology of far-reaching significance. It has changed the way of transactions in the real world and is regarded as the biggest change since the emergence of the Internet. [0003] Protecting user privacy is one of the most attractive features of cryptocurrency. If the user...

Problems solved by technology

Three months later, the bitcoins paid by the perpetrators have been exchanged for Monero, making it even more difficult to trace the real perpetrators

[0007] The above-mentioned cryptocurrencies such as Bitcoin, Monero, and Zerocoin did not consider the traceability of cryptocurrencies while protecting user privacy, and failed to achieve effective supervision of cryptocurrencies, making it difficult to balance user privacy and currency supervision in cryptocurrencies. Relationship

In the blockchain, although some methods for tracking anonymous cryptocurrencies have been proposed, there are not many existing methods for tracking cryptocurrencies based on cryptography tools, and there are very few tracking methods for Monero
