Abstract: Embodiments of this specification provide a payment service implementation method and apparatus. According to the method in the embodiments, when a payment service is performed, anonymous processing needs to be performed on original payment account information. First, a random number is used to perform transform processing on the original payment account information, so that information encrypted each time by using a public key is different. 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.
