In the internet world, all kinds of information of users are represented by a set of specific data, and various types of network systems need to identify the digital identity of users in order to confirm the corresponding operating rights. In the early days of the development of the Internet industry, password is the core element for the network system to identify the legitimate owner and operator of digital identity in the network (that is, to ensure that the physical identity of the operator corresponds to the digital identity).

With the development of the Internet industry to a new height, due to the openness and interconnection of computer systems, users' digital identities in the network are easily intercepted by criminals using Trojan virus and hacker software, resulting in various interests of users being infringed. Based on this, the network system needs a method or product to strengthen passwords, so as to ensure the unity of users' physical identity and digital identity, and therefore, secret protection is produced.
