Detailed Description
The technical solutions of the present invention are further described in detail below with reference to the drawings and examples, which should not be construed as limiting the present invention.
In this embodiment, a method for quickly obtaining a temporary password, as shown in fig. 1, includes:
step S1, when the device is started for the first time, guides the user to fill in an account for receiving the temporary password.
In the technical fields of internet, communication, video monitoring, internet of things and the like, a large number of networking devices exist. For example, in a video monitoring system, there are a webcam IPC, a network video recorder NVR, etc., and these devices are generally provided with a login password for a user to log in the device to configure the device. The embodiment is described by taking a monitoring device in a video monitoring system as an example, and is also applicable to electronic devices in other technical fields, and details are not described below.
In this embodiment, when the device is initially started, the user is guided to fill in an account for receiving the temporary password, that is, the user is guided to fill in a phone number or a mailbox for acquiring the temporary password when the user forgets to log in the password.
For example, when a user deploys a video monitoring system, the NVR is started, and the NVR is connected to an IP address or a serial port of the NVR through a configuration tool (such as a computer) to enter a login interface. The login interface displays an interface for inputting a login password, when a user inputs an initial login password, a guide interface is popped up immediately after the user successfully logs in, the user is required to input an account for receiving a temporary password (namely, the account for retrieving the password when the user forgets the password), and the account can be a mobile phone password or a mailbox address or both of the mobile phone password and the mailbox address need to be input.
After the user inputs the account number, the login is finished.
And step S2, the device encrypts the account for receiving the temporary password and the information for generating the temporary password to generate a dynamic two-dimensional code, and the dynamic two-dimensional code is displayed on a device login interface.
And the device records the account number for receiving the temporary password after receiving the account number filled by the user and used for receiving the temporary password. At this time, the device has an account number for the user to receive the temporary password, and the device itself has information for generating the temporary password, such as a device serial number and a device time. It should be noted that the information used for generating the temporary password may be the device serial number and the device time, or may be unique identification information of other devices, for example, the device name and the device time, which is not described herein again.
Under the condition that the equipment has the information, when the user logs in the equipment again, if the user forgets the password, the password retrieving button can be clicked, at the moment, the equipment encrypts the account for receiving the temporary password and the information for generating the temporary password, generates a dynamic two-dimensional code and displays the dynamic two-dimensional code on a login interface of the equipment.
For example, when the user logs in the NVR and finds that the password is forgotten, the password retrieving button is clicked, and the device generates a two-dimensional code and displays the two-dimensional code on a login interface.
In the embodiment, the device time is dynamic in the information for generating the temporary password, and the dynamic two-dimensional code is dynamically updated according to the device time. In the information carried by the two-dimensional code, the equipment time for generating the temporary password is the current equipment time for generating the two-dimensional code when the user forgets the password and needs to retrieve the password. The device time may be a date, or may be replaced with a finer time, for example, an hour or a minute, so that the two-dimensional code is dynamic, and can be refreshed at regular time, the device time in each generated two-dimensional code is different, for example, the device time is refreshed once every 5 minutes, and the device time difference between two previous two-dimensional codes and two subsequent two-dimensional codes is 5 minutes. And the account for receiving the temporary password and the information for generating the temporary password are encrypted to prevent the temporary password from being illegally cracked, so that the generated temporary password is sent to an illegal account.
In addition, when the user logs in the device again, the device encrypts the account for receiving the temporary password and the information for generating the temporary password to generate the dynamic two-dimensional code, and the dynamic two-dimensional code is displayed on the device login interface. And remark that 'forget password and scan the two-dimensional code to obtain the temporary password', replace the traditional password retrieving button, so that the user can directly scan the two-dimensional code when forgetting to log in the password.
And step S3, when the user forgets that the login password needs to acquire the temporary password, the user scans the two-dimensional code, acquires the encrypted account for receiving the temporary password and the encrypted information for generating the temporary password, and sends the encrypted account and the encrypted information to the cloud server.
The method comprises the steps that an account used for receiving a temporary password and information used for generating the temporary password are encrypted at the equipment to generate a dynamic two-dimensional code, and after the dynamic two-dimensional code is displayed on an equipment login interface, a user can scan the two-dimensional code by using an intelligent terminal (such as a smart phone, a smart tablet and other electronic equipment with two-dimensional code scanning capability) so as to obtain the encrypted information in the two-dimensional code and send the information to a cloud server.
According to the embodiment of the technical scheme, the two-dimensional code information further comprises the IP address of the cloud server, and the IP address information of the cloud server does not need to be encrypted, so that the user intelligent terminal can know the IP address of the cloud server after scanning the two-dimensional code, and can send the obtained encryption information to the cloud server. In this way, the intelligent terminal of the user does not need to install the client.
In a video monitoring system, in order to provide a real-time live situation for a user, a cloud server is usually deployed in a wide area network, and the user can check the live situation or a video after logging in the cloud server. The cloud server of the embodiment can be an independent server and can also be shared with the existing cloud server. The manufacturer of the device or the operator of the system may set a special cloud server for the device to provide the service of providing the temporary password for the user in the technical scheme.
For example, a user scans a two-dimensional code displayed on the NVR login interface by using a smart phone, acquires an IP address of the cloud server, acquires an encrypted account for receiving the temporary password and information for generating the temporary password, and sends the encrypted account and the information to the cloud server.
Another mode of this embodiment, user's smart mobile phone scans the two-dimensional code and uploads information to the high in the clouds server, installs corresponding customer end on smart mobile phone, and the customer end can be APP, little letter applet, public number etc. as long as can be mutual with the high in the clouds server. At this time, the two-dimensional code may not include the IP address of the cloud server, but may be set by default in the client or filled in the IP address of the cloud server.
Step S4, the cloud server reversely decrypts the received encrypted information, acquires the information for generating the temporary password, calculates the temporary password, and sends the temporary password to the account for receiving the temporary password.
The user smart phone is connected to the wide area network through communication modes such as WIFI or 4G, and therefore information can be sent to the cloud server. After the cloud server acquires the encrypted information (the encrypted account for receiving the temporary password and the encrypted information for generating the temporary password), decryption is performed first, and the account for receiving the temporary password and the encrypted information for generating the temporary password are acquired.
The cloud server is provided with a temporary password calculation tool, and the temporary password can be generated according to information used for generating the temporary password, such as the equipment serial number and the equipment time. And sending the generated temporary password to an account for receiving the temporary password. It is worth noting that the account number which is filled in when the user initially logs in the device is sent to the device, and is used for receiving the temporary password, and the mobile phone which scans the two-dimensional code is not used, so that the situation that an illegal user scans the two-dimensional code to cheat the temporary password is avoided.
For example: when the user initially logs in the device, the input account for receiving the temporary password is a mobile phone number 123456789, and the mobile phone number for scanning the two-dimensional code is 123456798, and after the temporary password is generated by the cloud server, the temporary password is sent to the mobile phone number 123456789 instead of the mobile phone number 123456798.
And step S5, after the user acquires the temporary password, the user logs in the equipment by using the acquired temporary password, the equipment compares the temporary password input by the user with the temporary password calculated by the equipment, and if the two temporary passwords are successfully matched, the equipment logs in successfully.
After the user acquires the temporary password, the user logs in the equipment by adopting the received temporary password, and a temporary password calculation tool embedded in the equipment is the same as a temporary password calculation tool installed on the cloud server and also calculates a temporary password.
The device matches the temporary password calculated by the device with the temporary password input by the user, and if the two temporary passwords are successfully matched (the passwords are the same), the device successfully logs in.
After the device successfully logs in, the device can further prompt the user to modify the login password, and after the user resets the login password, the temporary password is invalid. Therefore, the temporary password in this embodiment is a short-time valid password, and the time efficiency may be one day or several minutes.
Since the temporary password is time-efficient, particularly when the information for generating the temporary password is calculated not by date but by the current time of the device (which is accurate to minute), the current time obtained by the cloud is the time when the device generates the two-dimensional code, that is, the time when the device generates the two-dimensional code is used to generate the temporary password. After the user acquires the temporary password and logs in the device, the time for calculating the temporary password in the device is relatively delayed, and incorrect matching is easily caused. Therefore, according to the technical scheme, a temporary password fault-tolerant mechanism can be adopted for login.
In this embodiment, the temporary password fault-tolerant mechanism is adopted for login, that is, after the user acquires the temporary password, the user logs in the device by using the acquired temporary password, the device compares the temporary password input by the user with the temporary password calculated by the device itself according to the current device time or the temporary password calculated by the device time of the previous time, and if the matching is successful, the device logs in successfully.
For example, the two-dimensional code is refreshed every five minutes, that is, in the information for generating the temporary password, the interval between the two previous device times and the two subsequent device times is 5 minutes, and if the time when the user inputs the temporary password to log in is the time B, the device allows the logged-in temporary password to be logged in by two temporary passwords at the time B and the time B-5, so that a fault-tolerant mechanism within a certain time range is provided to ensure that the temporary password obtained by scanning the two-dimensional code is available. Wherein the time B-5 is the previous equipment time.
It should be noted that the temporary password calculation tools in the cloud server and the device themselves are the same, and the encryption algorithm on the device corresponds to the decryption algorithm on the cloud server one to one, which is not described herein again.
Corresponding to the method, the system for quickly acquiring the temporary password is also provided, and is used for acquiring the temporary password when a user forgets the login password of the device, and the system for quickly acquiring the temporary password comprises the following steps:
the device guides a user to fill in an account for receiving the temporary password when the device is started for the first time, encrypts the account for receiving the temporary password and information for generating the temporary password, generates a dynamic two-dimensional code and displays the dynamic two-dimensional code on a device login interface;
the scanning terminal is used for scanning the two-dimensional code when the user forgets that the login password needs to obtain the temporary password, obtaining an encrypted account for receiving the temporary password and information for generating the temporary password, and sending the encrypted account and the information to the cloud server;
the cloud server is used for reversely decrypting the received encrypted information, obtaining the information used for generating the temporary password, calculating the temporary password, and sending the temporary password to the account used for receiving the temporary password, so that the user can log in the equipment by adopting the obtained temporary password after obtaining the temporary password, the equipment compares the temporary password input by the user with the temporary password calculated by the equipment, and if the matching is successful, the equipment logs in successfully.
In this embodiment, the device needs to log in with a password, which is not described herein again. In correspondence with the above method, the preferred technical solution of the present invention is further illustrated below by way of examples.
