## Abstract

A business official email box based B2B service security verification method, includes: a service platform receiving an employee account and a password inputted by a business employee, and verifying whether the employee account and the password are legal or not; if yes, transmitting a log-in verification code to a business official email box to which the employee account corresponds; the service platform receiving a verification code inputted by the business employee, and determining whether the verification code is the log-in verification code or not; and if yes, the employee account successfully logging in the service platform. The present invention uses the association between the business employee and the business official email box in order to verify the identity of the business employee by means of the business official email box, and effectively prevent a resigned employee from logging in the service platform to improve the security of the platform.
