Description

technical field [0001] The invention relates to a computer network communication technology, in particular to a method and device for improving account security by using model analysis handwriting. Background technique [0002] Account security is a part of system security. How to prevent account theft and how to prevent the system from being maliciously hacked are account security. In the black and gray industry, there are personnel who are responsible for keeping accounts, mainly hoarding a large number of accounts on a certain platform, selling the accounts to others for profit, or stealing a large number of accounts from the account system of a certain platform, to Other platforms perform batch credential stuffing.

Problems solved by technology

However, for black industry, SMS authentication can rely on the access code platform to obtain a large number of available mobile phone numbers. Password authentication and secret authentication will not affect the batch number maintenance of black industry, and may not have a good effect on account theft, because many The passwords of people on different platforms are the same, black products can use batch credentialing to try

Face authentication is currently relatively safe, but there are certain restrictions on channels, such as PC, H5 and other channels. It is possible that the user's device does not have a camera
