In some embodiments, the privacy black box app102 saves the user information locally to the user device, e.g., the privacy black box app102 is in an encrypted storage area local to the user device.

At block 310, the privacy black box app sends the identity information to the public authority 104 for verification;

at block 315, the public authority mechanism 104 sends an identity authentication request to the user, receives a verification code sent by the user according to the identity authentication request, and performs and verifies the identity information; and sends the verification result to the privacy black box app 102;

in some embodiments, if the verification passes, a verification success result is sent to the privacy black box app 102; if the verification fails, a verification failure result is sent to the privacy black box app 102.

At block 320, privacy black box app102 receives the validation results of the public power mechanism.

In some embodiments, if the verification result is a verification failure result, the count is incremented by one, and if the count result is greater than or equal to a preset threshold, the privacy black box app102 is locked; if the counting result is smaller than the preset threshold value, the privacy black box app102 prompts the user to re-input the identity information so as to perform identity authentication on the user again according to the re-input identity information.

In some embodiments, if the verification result is a successful verification result, the privacy black box app102 is authorized to perform user registration or the like using the identity information.

Through the operation, the validity of the user identity information is proved, and the safety of the user identity information is ensured.

At block 210, the privacy black box app102 receives a user registration request for a trusted platform party; verifying the user registration request process through an independent verifier;

in some embodiments, the following sub-steps are included:

at block 405, the privacy black box app receives a registration request of a user for a trusted platform party, and generates a corresponding operation instruction;

in some embodiments, the operation instruction is an instruction instructing the operator 106 to perform pseudonymization processing on the identity information;

at block 410, privacy black box app102 sends the encrypted identity information and the operation instruction to operator 106;

in some embodiments, the user checks basic information that the user wants to hide in the privacy black box app102, and the privacy black box app102 encrypts unchecked information and additional information and sends the unchecked information and the additional information to the operator as encrypted identity information.

In block 415, the privacy black box app102 sends the verification success result, the encrypted identity information, the operation instruction and the contact information of the user to the independent verifier 108 for verification;

in some embodiments, before, after, or simultaneously with the encrypted identity information and the operation instruction being sent to the operator 106 by the privacy black box app102, the privacy black box app102 sends the verification success result, the encrypted identity information, and the contact information between the operation instruction and the user to the independent verifier 108 for verification.

At block 420, the independent verifier 108 performs user confirmation based on the user's contact details; sending a confirmation request to the user;

in some embodiments, the confirmation request may be a verification short message sent to the mobile phone number of the user.

In some embodiments, when the user confirms that the operation instruction is authorized for the user according to the confirmation request, the independent verifier 108 sends a key to the operator 106;

the key is used for decrypting the encrypted identity information, wherein the key used for encryption and decryption is agreed in advance by the independent verifier 108 and the privacy black box app102, and details are not repeated herein.

At block 425, the operator 106 receives the key sent by the independent verifier 108 after user verification, decrypts the encrypted identity information, and performs pseudonymization on the identity information according to the operation instruction; and sends the processing procedure record to the independent verifier 108 for verification;

at block 430, the independent verifier 108 verifies the processing procedure record, and if the verification is passed, the operator 106 is notified to send the pseudonymized information to the trusted platform;

in some embodiments, the independent verifier also sends the age of the pseudonymized information to the operator.

In some embodiments, if the authentication fails, a warning is issued and the phone verifies that the operator 106 is set as an untrusted operator. For example, a phone check with the user, truncate all keys subsequently sent to the operator 106, and notify the privacy black box app102 to select other operators 106 for operation.

At block 435, the operator 106 sends the pseudonymized information to the trusted platform, deletes the pseudonymized information, and sends the processing procedure record to the independent verifier 108 for verification;

in some embodiments, the operator 106 sets an automatic deletion program to delete the pseudonymized information.

At block 440, the independent verifier 108 verifies the process record and notifies the user if verification is successful.

In some embodiments, if the authentication fails, a warning is issued and verified telephonically.

In some embodiments, if the operator 106 sets an automatic deleting program to delete the information after pseudonymization processing, the independent verifier 108 verifies the processing procedure record, notifies the user if the verification is passed, and waits for the automatic deleting program to send a verification instruction; and if the verification instruction sent by the automatic deleting program is received, notifying the user that the information flow is finished.

In some embodiments, if the verification instruction sent by the automatic deleting program is not received, a warning is sent and the verification is carried out by telephone.

Through the above operation, it is ensured that the information sent by the operator 106 to the trusted platform is the information after pseudonymization processing, and the operator 106 does not keep the user identity information after the operation is finished, thereby protecting the user privacy.

Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombination.

Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are disclosed as example forms of implementing the claims.
