Detailed ways

It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

As shown in Figure 1, Figure 1 is a schematic diagram of the equipment structure of the hardware operating environment involved in the embodiment of the present invention.

As shown in Figure 1, a smart doorbell may include: a processor 1001, a network interface 1004, a user interface 1003, a memory 1005, a communication bus 1002, and a preset tamper-proof storage area 1006. Among them, the communication bus 1002 is used to realize connection communication between these components. Among them, the preset tamper-proof storage area 1006 can be an OTP (One Time Programmable, one-time programmable) storage area. The OTP storage area has the feature of one-time write, which can prevent the written content from being changed. In addition, it can also be used through the smart doorbell The MCU (Microcontroller Unit) reads and protects the OTP storage area to prevent the storage contents of the OTP storage area from being read by external illegal devices. Of course, the preset tamper-proof storage area 1006 can also be other storage areas that cannot be changed or illegally read after writing information. The user interface 1003 may include a display screen (Display) as a display unit, a keyboard as an input unit, or a touch screen (Touch Panel) that may also be used as an input unit in addition to the display unit. The optional user interface 1003 may also include standard wired interface and wireless interface. The network interface 1004 may optionally include a standard wired interface (such as a USB interface) and a wireless interface (such as a Bluetooth interface, Wi-Fi interface). The memory 1005 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may optionally be a storage device independent of the aforementioned processor 1001. Optionally, the smart doorbell can also include RF (Radio Frequency, radio frequency) circuits, sensors, audio circuits, Wi-Fi modules, Bluetooth modules, etc. Among them, the sensors may include various types of sensors such as barometer, hygrometer, thermometer, infrared sensor, etc., which will not be described in detail here.

Those skilled in the art can understand that the device structure shown in Figure 1 does not constitute a limitation on the smart doorbell, and may include more or fewer components than shown in the figure, or combine certain components, or arrange different components. .

As shown in Figure 1, memory 1005, which is a computer storage medium, may include an operating system, a network communication module, a user interface module, and a smart doorbell anti-piracy application.

In the device shown in Figure 1, the processor 1001 can be used to call the smart doorbell anti-piracy program stored in the memory 1005, and perform the operations of the following embodiments.

Referring to Figure 2, a first embodiment of the present invention provides a smart doorbell anti-piracy method. The smart doorbell anti-piracy method includes the following steps:

Step S100, when receiving a user binding request, verify the user binding request based on the product ciphertext in the preset tamper-proof storage area in the smart doorbell;

Specifically, the default tamper-proof storage area is a storage area that cannot be changed or illegally read after writing information, such as an OTP (One Time Programmable, one-time programmable) storage area. The product ciphertext is a ciphertext generated after encryption based on the product identification information of the smart doorbell. When the smart doorbell receives a user binding request, the user binding request may include requesting authentication information. Then the request authentication information in the user binding request can be verified based on the product ciphertext in the preset tamper-proof storage area in the smart doorbell, thereby determining whether the user binding request is a legitimate request, and then knowing whether the user For legitimate users. Even if an illegal user reads the storage content in the external flash memory of the smart doorbell and performs hardware copying to create a pirated product of the smart doorbell, the product in the preset tamper-proof storage area cannot be changed or read. Under the premise of ciphertext, it is obvious that the pirated product cannot be verified, which naturally results in the pirated product not being able to be used normally.

In this embodiment, when a user binding request is received, the user binding request is verified based on the product ciphertext in the preset tamper-proof storage area in the smart doorbell. On the one hand, the product ciphertext is stored in the preset tamper-proof storage area. The tamper-proof storage area prevents the product ciphertext from being changed or read. On the other hand, verifying the user binding request based on the product ciphertext also ensures the legality of the user binding request and determines the user's identity. legality.

Furthermore, step S100 includes:

Step S110, set an OTP storage area in the smart doorbell to use the OTP storage area as a preset tamper-proof storage area;

Step S111: Obtain the product secret text of the smart doorbell and store the product secret text in the OTP storage area.

Specifically, during the production process of the smart doorbell, the OTP storage area can be set in the smart doorbell so that the OTP storage area can be used as a preset tamper-proof storage area. The OTP storage area has a write-once feature, so it is physically guaranteed that the contents in the storage area will not be changed. In addition, the OTP storage area is integrated in the MCU (Microcontroller Unit), and read protection can also be set for the OTP storage area through the MCU to prevent the storage contents of the OTP storage area from being read by external illegal devices. Then the product identification information (such as DSN, (Device Serial Number, device serial number)) can be encrypted through the preset encryption tool (such as yubikey), the product ciphertext can be generated, and the product ciphertext can be stored in the in the OTP storage area. This ensures that the product password of the smart doorbell will not be changed and read by illegal devices.

In addition, before step S100, it also includes: when the user binding request is not received, a preset lock operation can be performed on the preset local function of the smart doorbell, so that the preset local function is in an inoperable state;

Specifically, the preset locking operation is an operation for disabling the preset local function. The preset local function may be a function that can be realized without the help of a preset cloud server after the smart doorbell is connected to the user's terminal device. When the user binding request is not received, a preset locking operation is performed on the preset local function of the smart doorbell, so that the preset local function is in an inoperable state. This ensures that pirated products cannot normally use the local functions of the smart doorbell without passing verification, thereby reducing the risk of smart doorbell piracy. Of course, it can be understood that the communication function (such as the Wi-Fi function module) of the smart doorbell is in a normal operating state to ensure that the user's terminal device can normally connect to the smart doorbell and send user bindings to the smart doorbell. ask.

Step S200, if the user binding request passes the verification, unlock the preset local function of the smart doorbell;

Specifically, the preset local function may be a function that can be realized without the help of a preset cloud server after the smart doorbell is connected to the user's terminal device, for example, receiving the Wi-Fi (Wireless LAN) user name and the user name sent by the terminal device. Password, and connect to Wi-Fi through the user name and password; send the video that collects the image information outside the door to the terminal device so that the user can observe the image outside the door; prompt visitor information and other functions. If the user binding request passes the verification, indicating that the user who sent the binding request is a legitimate user, the preset local function of the smart doorbell can be unlocked so that the user can normally use the preset local function. If the user binding request fails to pass verification, the preset local function is not unlocked, and a prompt message that fails to pass verification may be sent to the user's terminal device to prompt the user. In this embodiment, the user binding request passes the verification, indicating the legality of the user binding request. Therefore, the preset local function of the smart doorbell can be unlocked, thereby reducing the risk of smart doorbell piracy.

Step S300: After the smart doorbell establishes communication with the preset cloud server, obtain the verification ciphertext issued by the preset cloud server, and verify the verification ciphertext according to the product ciphertext;

Specifically, during the production process of the smart doorbell, the product identification information of the smart doorbell, such as DSN (Device Serial Number, device serial number), can be encrypted through a preset product encryption tool (such as yubikey) to generate a product ciphertext, and then write the product ciphertext into the preset tamper-proof storage area, and at the same time, upload the product ciphertext as the verification ciphertext of the smart doorbell to the preset cloud server for subsequent verification. In this embodiment, when the smart doorbell communicates with the preset cloud server, the preset cloud server sends the verification ciphertext corresponding to the smart doorbell to the smart doorbell, so that the smart doorbell Obtain the verification ciphertext. Furthermore, the verification plaintext information obtained after decrypting the verification ciphertext can be compared with the product identification information obtained after decrypting the product ciphertext. If the verification plaintext information matches the product identification information, it is determined that the verification password is The article is verified. If the verification plaintext information does not match the product identification information, it is determined that the verification ciphertext has failed the verification. Of course, the product ciphertext and the verification ciphertext can also be directly compared, and whether the verification ciphertext passes the verification is determined based on the comparison result. In this embodiment, the verification ciphertext issued by the preset cloud server is verified through the product ciphertext stored in the smart door lock, and the legitimacy of the smart door lock can be determined, thereby reducing the risk of smart doorbell piracy and improving the security of the smart doorbell. Security of cloud information for smart door locks.

In addition, before step S300, it also includes: performing a preset locking operation on the preset network function of the smart doorbell when there is no communication with the preset cloud server, so that the preset network function is in an inoperable state.

Specifically, the preset locking operation is also an operation for disabling the preset network function. The preset network function is a function that the smart doorbell needs to use the preset cloud server to implement. When there is no communication with the preset cloud server, a preset lock operation is performed on the preset network function of the smart doorbell, so that the preset network function is in an inoperable state. This ensures that pirated products cannot normally use the network functions of the smart doorbell without passing verification, thereby reducing the risk of smart doorbell piracy and improving the security of the smart doorbell's cloud information.

Furthermore, after the smart doorbell establishes communication with the preset cloud server, the step of obtaining the verification ciphertext issued by the preset cloud server includes the following steps:

Step S310: After the smart doorbell establishes communication with the preset cloud server, receive the encrypted verification ciphertext issued by the preset cloud server;

Step S311: Decrypt the encrypted verification ciphertext to obtain the verification ciphertext.

Specifically, when the smart doorbell communicates with the preset cloud server, the communication information transmitted between each other can be encrypted through the preset communication encryption method. The preset communication encryption method can be a symmetric encryption algorithm and/or symmetric encryption. Algorithm, there is no restriction on this in this embodiment. After the smart doorbell establishes communication with the preset cloud server (of course, it can also be established at the same time as the smart doorbell establishes communication with the preset cloud server), the encrypted verification ciphertext issued by the preset cloud server is received. Afterwards, the verification ciphertext is obtained by decrypting the encrypted verification ciphertext. In this embodiment, the verification ciphertext is encrypted using a preset communication encryption method, which can improve the security of communication between the smart doorbell and the preset cloud server.

Furthermore, the verification of the verification ciphertext according to the product ciphertext includes the following steps:

Step S320, determine whether the verification ciphertext matches the product ciphertext;

Step S321, if they match, it is determined that the verification ciphertext passes the verification.

Specifically, by comparing the product ciphertext in the preset tamper-proof storage area with the verification ciphertext, when the product ciphertext matches the verification ciphertext, it is determined that the verification ciphertext passes the verification. When the product ciphertext does not match the verification ciphertext, it is determined that the verification ciphertext fails the verification. In this embodiment, by directly comparing the verification ciphertext and the product ciphertext, there is no need to increase the decryption process, and the efficiency of smart doorbell verification can be improved.

Furthermore, step S300 also includes the following steps:

Step S330: Encrypt the product ciphertext to obtain the encrypted product ciphertext;

Step S331: Send the encrypted product ciphertext to the preset cloud server, so that the preset cloud server verifies the encrypted product ciphertext.

Specifically, when the smart doorbell communicates with the preset cloud server, the smart doorbell can also send the product ciphertext to the preset cloud server for verification by the cloud server. The smart doorbell can encrypt the product ciphertext through a preset communication encryption method to obtain the encrypted product ciphertext. Then, the encrypted product ciphertext is sent to the preset cloud server, so that the preset cloud server can decrypt the encrypted product ciphertext, so as to decrypt the encrypted product ciphertext according to the verification ciphertext. The product secret text obtained later is verified. If the product secret text passes the verification, the preset cloud server can allow information interaction between the smart doorbells. In this embodiment, while the smart doorbell locally verifies the preset cloud server, the product cipher text is sent to the preset cloud server so that the preset cloud server verifies the smart doorbell, thereby improving the performance of the smart doorbell. Security of information in the cloud.

Step S400: If the verification ciphertext passes the verification, the preset network function of the smart doorbell is unlocked.

Specifically, the preset network function is a function that the smart doorbell needs to use the preset cloud server to implement. For example, uploading a video that collects image information outside the door to the preset cloud server, so that the user can remotely view the images outside the home. Image; upload the video of the image information outside the door to the preset cloud server to save the video and other functions. When the verification ciphertext passes the verification, indicating that the smart doorbell communicating with the preset cloud server is a legitimate device, the preset network function of the smart doorbell can be unlocked so that the smart doorbell can communicate with the preset cloud server. The cloud server is configured to interact with information and run the preset network functions normally.

In the first embodiment of the present invention, when a user binding request is received, the user binding request is verified based on the product ciphertext in the preset tamper-proof storage area in the smart doorbell. If the user binding request passes the verification, indicating that the user who sent the binding request is a legitimate user, the preset local function of the smart doorbell can be unlocked so that the user can normally use the preset local function. After the smart doorbell establishes communication with the preset cloud server, the verification ciphertext issued by the preset cloud server is obtained, and the verification ciphertext is verified based on the product ciphertext. When the verification ciphertext passes the verification, indicating that the smart doorbell communicating with the preset cloud server is a legitimate device, the preset network function of the smart doorbell can be unlocked so that the smart doorbell can communicate with the preset cloud server. The server exchanges information and runs the preset network functions normally. In this embodiment, the product ciphertext is stored in a preset tamper-proof storage area to prevent the product ciphertext from being changed or read. When the user binds the smart doorbell and the smart doorbell communicates with the preset cloud server, the product ciphertext is stored based on the preset cloud server. The product ciphertext verifies the user binding request and the verification ciphertext corresponding to the smart doorbell issued by the preset cloud server to ensure the legitimacy of the user and the smart doorbell, thereby ensuring that pirated smart doorbell products cannot be used normally. , reducing the risk of smart doorbell piracy.

Further, referring to Figure 3, a second embodiment of the present invention provides a smart doorbell anti-piracy method. Based on the embodiment shown in Figure 2, step S100 includes the following steps:

Step S120, when receiving a user binding request, read the request authentication code in the user binding request;

Step S130, generate a product authentication code based on the product ciphertext;

Step S140, determine whether the request authentication code matches the product authentication code;

Step S141, if they match, it is determined that the user binding request passes the verification.

Specifically, the request authentication code is an authentication code generated based on product identification information, and the product ciphertext is product information encrypted by a preset product encryption method. During the production process, the request authentication code can be generated based on the product identification information (such as DSN) of the smart doorbell based on a preset security algorithm, where the preset security algorithm is used to convert the product identification information in an irreversible form. This is the algorithm for requesting the authentication code. For example, product identification information takes DSN as an example. The DSN can be irreversibly converted into a piece of ciphertext through the SHA1 secure hash algorithm. The hex value of the last 4 digits of the ciphertext is then converted to Decimal number, take the last 6 digits of the decimal number, and use these 6 digits as the request authentication code. A request authentication code can be printed or pasted in the package of the smart doorbell, and the request authentication code is an authentication code generated based on the product cipher text. Wherein, the request authentication code may be in the form of barcode, QR code, character string, etc. When a user needs to bind the smart doorbell through a terminal device (such as a smartphone, tablet, etc.), he or she can scan or input the request authentication code to generate a user binding request and send it to the smart doorbell. Therefore, when a user binding request is received, the request authentication code contained in the user binding request can be read. Then, the product cipher text is decrypted to obtain the corresponding product identification information, and then the product authentication code is generated based on the same preset security algorithm based on the product identification information. Then, determine whether the request authentication code matches the product authentication code. If the request authentication code matches the product authentication code, it means that the product ciphertext in the smart doorbell corresponds to the request authentication code in the user binding request, and the user binding request is a legitimate request, then it is determined that the user binding request The specified request is verified. If the request authentication code and the product authentication code do not match, it means that the product ciphertext in the smart doorbell does not correspond to the request authentication code in the user binding request, and the user binding request is an illegal request, and the user is determined Binding request failed validation. In this embodiment, the user binding request includes a request authentication code, and the request authentication code is compared with the product authentication code generated according to the product cipher text, thereby determining that the smart doorbell is bound to the user Whether the request corresponds to determine whether the user binding request passes the verification.

Furthermore, step S130 also includes the following steps:

Step S131: Decrypt the product ciphertext based on a preset decryption algorithm to obtain a product identification code;

Step S132: Calculate the product identification code based on a preset security algorithm to obtain a product authentication code.

Specifically, the product ciphertext is the ciphertext generated after the product identification code (such as DSN) is encrypted by a preset product encryption algorithm. Therefore, through the preset decryption algorithm corresponding to the preset product encryption algorithm, the product ciphertext can be decrypted into the corresponding product identification code. Then, based on the generation method of the request authentication code, the corresponding product authentication code is calculated according to the product identification code. Then, the product authentication code can be compared with the request authentication code in the user binding request.
