Account transfer method, apparatus and device for preventing tracking transaction transfer-out party, and storage medium

Abstract

The invention relates to the technical field of blockchain, and discloses an account transfer method for preventing tracking of a transaction transfer-out party, which comprises the following steps that: during an account transfer transaction, generating real transaction information between the transaction transfer-out party PartyX and a transaction transfer-in party PartyM by a transaction transfer-out party PartyX; introducing n virtual transaction transfer-out parties PartyN, and generating virtual transaction information corresponding to a virtual transaction amount b between the virtual transaction transfer-out parties PartyN and the transaction transfer-in parties PartyM; generating a secret key KeyN which can be decrypted by a transaction transfer-out party PartyX, a virtual transaction transfer-out party PartyN and a transaction transfer-in party PartyM by a Pairing algorithm; and publishing the real transaction information and the virtual transaction information to the blockchain. The invention further discloses an account transfer device and equipment for preventing the transaction transfer-out party from being tracked and a computer readable storage medium. According tothe method, the purpose of hiding the identity of the transfer-out party is achieved by using a plurality of virtual transactions, and the transfer-out party of the real transaction can be identifiedonly by the transaction transfer-in party, so that the traceability of the identity of the transaction transfer-out party is ensured.

Description

technical field [0001] The present invention relates to the technical field of block chains, and in particular to a transfer method, device, equipment and computer-readable storage medium for preventing tracking of transaction transferees. Background technique [0002] At present, the commonly used method in the industry is to use the public key address (the hash value of the public key) as the identity of both parties to the transaction, and think that this method is safe. This is actually a misunderstanding of cryptography. Using the public key as an identity is just a pseudonym, and under the big data analysis of today's computers, it is easy to count the user behavior characteristics under this pseudonym, and to analyze these characteristics (such as user portraits), it is likely to be The identity of the public key address is located. If the user also leaks some information offline, the combination of the two may infer the corresponding relationship between the user's r...
