Then, the public key and an encryption algorithm obtained in advance are used to encrypt payment account information obtained after the transform processing, so as to obtain anonymous payment account information, thereby completing an anonymous processing process. After anonymous processing is completed, the obtained anonymous payment account information may be used to perform a payment operation.
