Identity authentication technology is an effective solution in the process of confirming the identity of the operator in the computer network. ? All information in the computer network world, including the user's identity information, is represented by a specific set of data. Computers can only identify users' digital identities, and all authorizations to users are also authorizations to users' digital identities. ?
How to ensure that the operator who operates in a digital identity is the legal owner of this digital identity, that is to say, to ensure that the physical identity of the operator corresponds to the digital identity, identity authentication technology is to solve this problem. As the first gateway to protect network assets, identity authentication plays an important role.
The user's password is set by the user himself. Enter the correct password when logging in to the network, and the computer will think that the operator is a legitimate user. In fact, in order to avoid forgetting the password, many users often use easily guessed strings such as birthdays and phone numbers as passwords, or copy the passwords on paper and put them in places they think are safe, which can easily lead to password leakage.
If the password is static data, it needs to be stored in the computer memory during the verification process, and may be intercepted by Trojan horse programs or the network during the transmission. Therefore, the static password mechanism is very simple to use or deploy, but from the security point of view, the username/password method is an unsafe authentication method. It uses the method you know.
