The invention aims to provide a method and equipment for providing a picture verification code based on a verification security level. The method comprises the following steps: enabling the verification code providing equipment to acquire a verification request submitted by a user in a visited page through user equipment; according to user related information of the user, determining a verification security level corresponding to the verification request; according to the verification security level, acquiring a picture verification code corresponding to the verification request; and providing the picture verification code to the visited page. Compared with the prior art, the invention can provide picture verification codes of different levels based on verification security levels, thereby increasing the machine recognition difficulty, and simultaneously facilitating user verification and improving the use experience of the user.
