1. A recognition method applied to a security system, wherein the security system comprises a first camera and a processor, and the method comprises:
obtaining, by the processor, at least two first images acquired by the first camera and representing images of a payment behavior of a first user;
analyzing, by the processor, the at least two first images to obtain a first analysis result representing a payment result generated by the payment behavior;
determining, by the processor, identity information of the first user according to the first analysis result, the identity information representing whether the first user is a suspected user who has not made payment;
obtaining, by the processor, physiological characteristic information of the first user from at least one of the at least two first images, in response to determining the identity information of the first user to represent that the first user is the suspected user who has not made payment;
storing, by the processor, the physiological characteristic information of the first user;
obtaining, by the processor, at least one second image acquired by a second camera;
obtaining, by the processor, physiological characteristic information of a user in the at least one second image;
performing, by the processor, similarity match between the physiological characteristic information of the user and stored physiological characteristic information of users; and
determining, by the processor according to a result of the similarity match, whether first reminder information is generated, the first reminder information reminding that the user is a historical suspected user.
