Block chain address transformation and identity authentication method and device and storage medium

Abstract

The invention belongs to the technical field of computers, particularly relates to a block chain address transformation and identity authentication method and device and a storage medium, and has the advantages that it is guaranteed that information of a user cannot be revealed when the user registers an address, identity card information is provided only when identity verification is needed (such as asset retrieval). On the other hand, the identity hash first random character string, the identity information and the private information are obtained through N times of hash operation instead of performing hash operation by directly adopting an identity card number conventionally, so that the privacy security of the user is ensured; the situation that a hacker uses an identity card coding rule or collects a large amount of identity card information to carry out brute force cracking and corresponds to an account address to obtain user identity information is avoided, the cost of address information cracking is increased by adopting hashN operation, a certain cracking duration is increased, the duration of obtaining identity hash is set by setting N. Hackers cannot try various components for many times in a short time to form brute force cracking.

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to a block chain address modification and identity authentication method, device and storage medium. Background technique [0002] Blockchain wallet retrieval technology or social wallet technology is generally based on two private keys, one private key can transfer money instantly, while the other private key can realize delayed transfer, through the different permissions of the two private keys, the wallet Assets within are recovered. Under normal circumstances, the private key for delayed transfer, that is, the retrieved private key, will be stored in a third-party organization, and then verified through methods such as real-name verification. If the verification is passed, the asset will be retrieved. Among many verification schemes, the identity It is one of the most mainstream and reliable methods to confirm name registration and then verify face authentication....

Problems solved by technology

In other words, it is impossible to simply perform parallel acceleration. The most common type of VDF is to perform N hash operations on a string, because the next operation must wait for the end of the previous operation, and the current computing power of a single CPU core is mainly related to The main frequency is related. As for the main frequency parameters of the CPU, the performance difference between the worst CPU and the best CPU is no more than 5 times, and the main frequency of the general household CPU is 2G hz. The fastest CPU can probably be about 3 times faster
