All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
fig. 1 is a flowchart of a method for managing factory-set passwords for vehicle-mounted navigation, which is applied to a vehicle-mounted navigation system according to an embodiment of the invention. Optionally, the vehicle-mounted navigation system in the embodiment of the present invention sets an application carrier for a factory, and is implemented by using a vehicle-mounted computer based on an Android system or a Linux system, which is commonly used in the prior art, or by using a vehicle-mounted computer based on a WinCE system, a ucos ii system, or a ucos iii system. As shown in fig. 1, the method specifically includes the following steps:
step S102, generating a first password based on the current timestamp information.
Specifically, the vehicle-mounted navigation system dynamically acquires the current timestamp information of the system, then generates a first password by using the current timestamp information based on a preset algorithm, and uses the first password as a password set when the vehicle-mounted navigation system enters a factory.
And step S104, encrypting the first password by using a preset public key to obtain ciphertext information.
Optionally, the ciphertext may be generated by using algorithms such as MD5, RSA, DSA, DES, and the like, or may be generated in other forms, and the specific encryption method is not specifically limited in the embodiments of the present invention.
And step S106, sending the ciphertext information to the user terminal so that the user terminal can obtain a second password based on the ciphertext information.
Preferably, the user terminal is a smart phone, and the user terminal provided by the embodiment of the invention can receive the ciphertext information sent by the vehicle-mounted navigation system through special application software installed in the system.
Alternatively, the ciphertext information may be sent to the user terminal in the form of a two-dimensional code, or may be sent to the user terminal in the form of a barcode, a character string, a number, a character, or the like.
Preferably, a target two-dimensional code is generated based on the ciphertext information; the target two-dimensional code carries ciphertext information; and displaying the target two-dimensional code to a user terminal so that the user terminal can obtain the ciphertext information by scanning the target two-dimensional code.
After the user terminal acquires the ciphertext information, the server can send the ciphertext information, then the server carries out decryption operation on the ciphertext information to obtain a second password after decryption, and finally the server returns the second password to the user terminal.
And step S108, acquiring a second password input by the user.
Specifically, after the user obtains the second password through the user terminal, the second password may be manually input into a password input interface of the vehicle navigation system when entering the factory setting.
Step S110, determining whether the second password is matched with the first password, and obtaining a matching result.
Specifically, the vehicle navigation system compares whether the second password is consistent with the first password, and then obtains a matching result, that is, the correctness of the password input by the user is judged, wherein the matching result includes any one of the following items: the second password is matched with the first password, and the second password is not matched with the first password. Alternatively, the matching mode can be realized by character string comparison, MD5 code comparison, check code comparison, and the like.
Optionally, after obtaining the matching result, the method further includes:
if the matching result is that the second password is matched with the first password, entering factory setting of the vehicle navigation system; and if the matching result is that the second password is not matched with the first password, sending out error prompt information.
The embodiment of the invention provides a management method for factory-set passwords for vehicle-mounted navigation, which is characterized in that a time fusion mechanism is added in the password generation process, and the passwords can be changed along with the change of time, so that the passwords have dynamic property.
Fig. 2 is a flowchart of another vehicle navigation factory setting password management method according to an embodiment of the invention, which is applied to a user terminal. As shown in fig. 2, the method specifically includes the following steps:
step S202, acquiring ciphertext information generated by the vehicle navigation system; the ciphertext information is the ciphertext information obtained by encrypting the first password by using a preset public key.
Optionally, the ciphertext information may be obtained by scanning a target two-dimensional code, where the target two-dimensional code is a two-dimensional code carrying the ciphertext information. The ciphertext information can also be input in the form of an information input box.
Step S204, sending the ciphertext information to a server so that the server decrypts the ciphertext information based on a preset private key to obtain a second password; the preset private key is a private key corresponding to the preset public key.
Alternatively, the server may be a cloud computer or a cloud server.
And step S206, acquiring a second password returned by the server.
And S208, displaying the second password to the user so that the user inputs the second password into the vehicle-mounted navigation system and the vehicle-mounted navigation system verifies the second password.
Optionally, before step S202, the method further includes: authenticating identity information of a user, specifically comprising:
first, authentication information of a user is acquired. Optionally, the authentication information of the user may be acquired by collecting a "user name + password", or may be implemented by identity verification methods such as face recognition, voiceprint recognition, fingerprint recognition, and the like.
And then, sending the authentication information to the server so that the server verifies the authentication information and obtains a verification result. Specifically, a cloud database is arranged in the server and used for storing authentication information of the user; optionally, the cloud database may be implemented by MYSQL, or may be stored in forms of Oracle, file, linked list, or the like.
And finally, obtaining a verification result returned by the server. If the verification result is that the verification is passed, the user terminal allows the user to continue operating; if the verification result is verification failure, the user terminal forbids the user to continue operation, the password cannot be acquired, the user needs to resend the authentication information to the server, and the subsequent operation can not be continued until the verification result is verification passing.
In the embodiment of the invention, if a user wants to enter a factory setting interface of the vehicle-mounted navigation system, the user firstly receives a target two-dimensional code displayed by the vehicle-mounted navigation system, wherein the target two-dimensional code comprises ciphertext information obtained by encrypting a password; and then the user needs to pass identity authentication, enter an application APP of the user terminal, then scan the target two-dimensional code through the user terminal to obtain ciphertext information, the user terminal sends the ciphertext information to the server, the server can decrypt the ciphertext information to obtain a decrypted password, and return the decrypted password to the user terminal, the user manually inputs the password to an authentication interface of a factory setting interface of the vehicle-mounted navigation system according to the password received by the user terminal, and the user enters factory setting after password authentication of the vehicle-mounted navigation system. The embodiment of the invention improves the safety of the password use of the vehicle navigation system through the password generation process, the password acquisition process and the identity management process of the password acquirer.
