Embodiment 1

[0065] Embodiment 1: A digital asset management method that can realize anonymous transactions, such as figure 1 and figure 2 shown, including the following steps: including the following steps:

[0066] Obtain the asset owner registration request, and when receiving the asset owner's registration request, obtain a unique seed and store it in the asset owner's wallet;

[0067] Using the unique seed to derive two key pairs, the two key pairs are the user signature key pair and the user transaction key pair;

[0068] Obtain a digital asset registration request, generate digital asset information, and use the user transaction key pair and random key pair to generate a symmetric key;

[0069] Encrypting the digital asset information with the symmetric key and the user signature key pair to generate first verifiable information and first encrypted information;

[0070] Casting the digital asset information into the first NFT, generating the first transaction information and upl...

Embodiment 2

[0146] Embodiment 2: A digital asset management device that can realize anonymous transactions, including

[0147] User registration module: obtains the registration request of the asset owner, and when receiving the registration request of the asset owner, obtains a unique seed and stores it in the wallet of the asset owner; derives two key pairs from the unique seed , the two described key pairs are respectively the user signature key pair and the user transaction key pair;

[0148] Digital asset registration and verification module: obtain digital asset registration request, and generate digital asset information, use the user transaction key pair and random key pair to generate a symmetric key; use the symmetric key and the user signature key Encrypting the digital asset information to generate first verifiable information and first encrypted information; casting the digital asset information into the first NFT, generating the first transaction information and upload...

Abstract

The embodiment of the invention discloses a digital asset management method capable of realizing anonymous transaction, and the method comprises the steps: packaging digital assets into digital asset information through a secret key system and an encryption algorithm, packaging the digital asset information into encryption information and verification information, and carrying out the chain for evidence storage. The owner of the digital asset or the buyer of the digital asset can obtain the digital asset information by generating a symmetric encryption (decryption) key. And the encrypted information is used as a public key of each digital asset to replace a traditional user name and is used as an account identifier of the centralized service platform for collecting user use data. The unique code of the digital asset packaged in the digital asset information serves as a private key of the digital asset, the ownership of the digital asset can be verified, and the ownership of the digital asset can be relieved through logout of the unique code of the digital asset. And the uplink information is not directly associated with the key pair of the user, so that the reality of the user and the privacy of the network identity are guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of digital asset management, in particular to a digital asset management method that can realize anonymous transactions. Background technique [0002] With the popularization of the Internet, especially the mobile Internet, the production, processing, circulation and utilization of data has not only developed into a huge industry, but also subversively changed the way people produce, live and consume, and promoted profound changes in various fields. The digital economy where data is the means of production came into being. In contrast to the booming digital economy and digital assets, the boundaries of people's daily life have expanded from the offline physical world to the online space, leading to issues such as digital security and digital divide, especially the large number of users collected by digital assets and Internet companies. How data should be owned and managed has arou...
