Correction page (Article 91) Optionally, the user information is encrypted by using an irreversible algorithm, such as using the message digest algorithm fifth edition (Mes sage D i ges t Al gor i thm , MD5 ) to user information, and the power is dense, The confidential user information is a ciphertext that cannot be decrypted.

Optionally, the user information is encrypted by a unique numbering method, and the encrypted user information is a unique number. For example, the user information 1 is encrypted by a unique numbering method, that is, the user information 1 corresponds to a number 1234567, which is unique and corresponds to only the user information 1. When the user information is obtained, the user information corresponding to the number 1234567 can be obtained by querying the correspondence table of the unique number and the user information. If there is no corresponding table with unique number and user information, the real user information will not be obtained, and the confidentiality can be achieved.

The gateway encrypts user information and sends it to the service provider through service packets to effectively prevent user information from leaking.

Step S102: Acquire user charging information corresponding to the encrypted user information.

The service provider cannot decrypt the encrypted user information after receiving the encrypted user information, but can use the encrypted user information to obtain the user charging information recorded locally by the service provider.

Specifically, although the service provider cannot know the real user information, each encrypted user information corresponds to the unique user information, so the service provider can know the user corresponding to the encrypted user information according to the time sequence of the user requesting the service content. Billing information.

Step S103: Send the encrypted user information, the user network address, and the user charging information to the settlement center.

The operator's settlement center confirms whether the user billing information obtained by the service provider is accurate based on the encrypted user information sent by the service provider and the user network address.

Specifically, the settlement center stores a corresponding list of encrypted user information and user information, and the settlement center queries the corresponding list according to the received encrypted user information to obtain real user information. It is then confirmed whether the real user information receives the service content using the user network address received simultaneously with the encrypted user information within the time period corresponding to the user charging information. If the real user information is When the service content is received by the user network address received simultaneously with the encrypted user information in the time period corresponding to the user charging information, the user charging information is correct, and the settlement center records the user charging information.

In addition, after step S102, the following steps are further included:

The stored encrypted user information, the user network address, and the obtained user charging information are saved, and the step S130 is specifically to periodically send the received encrypted user information, the user network address, and the acquired user to the service center. Fee information.

Step S201: Receive encrypted user information, a user network address, and user charging information sent by the service provider.

The service provider receives the encrypted user information and the user network address sent by the gateway, and the service provider does not need to obtain the real user information, and locally obtains the user charging information corresponding to the encrypted user information according to the encrypted user information. The encrypted user information, the network address, and the obtained user billing information are then sent to the operator's settlement center.

Optionally, the user information is encrypted by using an irreversible algorithm, such as encrypting the user by using the MD5 algorithm, and the encrypted user information is a ciphertext that cannot be decrypted.

Optionally, the user information is encrypted by a unique numbering method, and the encrypted user information is a unique number.

Step S202, from the encrypted user information and the user information stored in advance according to the encrypted user information. Query user information in the corresponding list of interest.

The settlement center pre-stores a corresponding list of encrypted user information and user information, and the settlement center queries the real user information corresponding to the encrypted user information from the corresponding list to check whether the user billing information is accurate.

Step S203: Confirm whether the user charging information is accurate according to the user network address and the user information. Specifically, it is confirmed whether the real user information receives the service content by using the user network address received at the same time as the encrypted user information in the time period corresponding to the user charging information. If the real user information receives the service content using the user network address received simultaneously with the encrypted user information within the time period corresponding to the user billing information, the user billing information is correct.

Step S204: If the user charging information is accurate, charging is performed.

With the charging method provided by the embodiment, the settlement center of the operator confirms whether the user billing information corresponding to the encrypted user information received at the same time is accurate according to the received encrypted user information and the user network address. During the entire billing process, only the settlement center can obtain real user information according to the encrypted user information and the corresponding list of user information, thereby effectively preventing the user information from being leaked to third party devices other than the operator.
