DETAILED DESCRIPTION OF EMBODIEMTNS
Principles of the present disclosure will now be described with reference to several example embodiments shown in the drawings. Though example embodiments of the present disclosure are illustrated in the drawings, it is to be understood that the embodiments are described only to facilitate those skilled in the art in better understanding and thereby achieving the present disclosure, rather than to limit the scope of the disclosure in any manner.
As described above, in prior art, for a door entry device with a display, it is inconvenient to preform commissioning via the door entry device’s own screen and keypad, especially in a situation of inputting some texts. And for a door entry device without a display, normally a computer or other auxiliary equipment is necessary, an operator needs to build up a correct connection between the door entry device and the computer or other auxiliary equipment before commissioning, it is quite low efficient.
In particular, traditional door entry devices mainly have the following several traditional initial commissioning modes: entering a setting menu via a keypad or a touch screen on a device, and then finishing the initial commissioning by input or selection; or implementing a service in a device, and connecting a computer or a cell phone to the device in a way such as Ethernet, WIFI, Bluetooth and RS-485, and then preforming the initial commissioning on the computer or the cell phone. However, due to the cost consideration, many door entry devices may not be equipped with high performance processor, large memory, touch screen of large size, WIFI module or Bluetooth module, and thus, initial commissioning on the device takes a lot of time, which brings poor user experience. Furthermore, since a correct connection needs to be set up beforehand, the initial commissioning via a computer or other auxiliary equipment is also not convenient. Therefore, there is a need in the art for an improved manner for setting door entry devices to enhance product competitiveness and improve user experience.
The present invention innovatively proposes encoding the setting information of a door entry device to an information code, and using the device’s camera to preform quick commissioning. Moreover, in the present invention, a Universally Unique Identifier (UUID) of a device and digital signature mechanism are innovatively introduced to ensure the security of commissioning.
In some embodiments, the information code can be a quick response code (QR-code) . In other embodiments, the information code can be a data matric code (DMC-code) . In other embodiments, the information code can be a bar code. In other embodiments, the information code can be any other suitable code. In the drawings of the present application, for schematic purpose only, the information code is represented by a QR-code. However, it should be appreciated that the QR-code is only a schematic example and the information code of the present invention is not limited it.
As shown in Figure 1, a door entry device 1 includes a camera 10 and a button 11. The camera 10 is used to capture or scan an object for receiving input from another party. In some embodiments, the camera 10 is used to scan a quick response (QR) -code (two-dimensional code) for receiving setting information from another part, for example, a cell phone of an operator, a user or an installer.
Still refer to Figure 1, in some embodiments, an information code 20 is shown on a screen of a cell phone. The camera 10 scans the information code 20 to obtain the setting information. In other embodiments, the cell phone can be replaced by other devices that can show the information code. For example, a computer, a tablet computer, a PAD and so on can be used to provide the information code for setting. In some embodiments, the information code can be shown in a form of photo or picture. In other embodiments, other media can be used to provide the information code for setting. For example, a printed information code on a paper can be used for setting. In other embodiments, any other appropriate device or medium can be used for showing the information code.
For triggering the setting or for the initialization of the door entry device 1, some particular actions of a user on the button 11 can be utilized. For example, a long press on the button 11 can trigger the setting or the initialization of the door entry device. Alternatively, several consecutive short presses can trigger the setting or the initialization of the door entry device 1, for example, with two or more consecutive short presses. In other embodiments, any other appropriate actions can be used for triggering the setting or for the initialization of the door entry device.
Although Figure 1 shows a button for triggering, it should be appreciated that the door entry device may have no button. For example, the triggering can be performed by actions on a touch screen of the door entry device. The button shown in Figure 1 is only a schematic example and is not used to limit the present invention.
Figure 2 illustrates a process 200 for producing an information code. As shown in Figure 2, at block 201, parameters for a door entry device are edited on a cell phone or a computer. At block 202, the parameters are converted into an information code, for example, by an information code generator, in which the information code generator can be incorporated in software for generating the information code in the cell phone or the computer. The information code is shown on the screen of the cell phone or the computer at block 203. Alternatively, the information code is sent from the computer to a mobile device for showing the information code. In other embodiments, the information code is printed out on a paper.
For example, the parameters can be embodied as various values for representing different kinds of characters, as follow:
Parameter 1= value 1
Parameter 2= value 2
…
Parameter n= value n.
For example, parameter 1 (value 1) can be associated with the address of the building. Parameter 2 (value 2) can be associated with identity of the user. Parameter 3 (value 3) can be associated with the authority of the user. Parameter 4 (value 4) can be associated with the date. Parameter 5 (value 5) can be associated with the time. Parameter 6 (value 6) can be associated with the term of validity of the setting. Parameter 7 (value 7) can be associated with room numbers in the building. Parameter 8 (value 8) can be associated with volume. The above parameters are only exemplary. Different parameters can be involved in some embodiments. And the parameters can be provided in a parameter table in any appropriate order.
Figure 3 illustrates a method 300 using a camera and an information code to achieve quick setting for a door entry device. In some embodiments, at 301, when the door entry device is initialized or when the door entry device is updated or restarted, the door entry device will load the firmware and preform initialization at the device side.
At 302, parameters for configuring the door entry device are edited on a computer or cell phone at the user side. In other embodiments, the parameters can be edited on any other appropriate computing device.
At 303, the parameters or a parameter table including these parameters is converted into an information code via an information code generator. In some embodiments, the parameters or a parameter table including these parameters is encoded to an information code via an information code generator. The information code generator can be incorporated in the user side device or can be a module in the user side device.
At 304, the information code is shown on a screen of the user side device. For example, the information code can be sent from a computing device to a cell phone of the user. Alternatively, the information code can be printed out on a paper.
Then, at the device side, an information code scanning mode is implemented in the software of the door entry device at 305. In this mode, the camera is switched on for scanning or receiving the information code information. And some actions or operation (for example, long pressing a button for several seconds) can be employed to switch the door entry device to the information code scanning mode, and in this mode, an appropriate sound indication or light indication can be used to indicate the user that the door entry device is in the information code scanning mode. In other embodiments, other indications can be used.
At 306, the information code is shown in front of the camera of the door entry device. The camera of the door entry device scans the information code in order to obtain the information code information (for example parameters for setting) from the information code.
At 307, the door entry device collects the information code by the camera and then decodes the information code to obtain the information code information (for example parameters for setting) from the information code. And the door entry device saves and refreshes the parameters by writing the decoded information code information into the door entry device. At the end, the setting is finished and the door entry device exits the information code scanning mode.
The steps mentioned above refer to how to generate parameters for setting a door entry device and convert them to an information code. In order to improve the user experience, in some embodiments, an application can be implemented in a computer or a cell phone, which can receive the input or selection from the user as parameters, and then convert them to information code directly.
In order to prevent illegal users changing the setting of the door entry device by importing an information code generated by themselves, on the basis of the implementation of the present invention, a digital signature mechanism is introduced here.
“Encryption” refers to a process of encoding parameters or data in order to hide its content from other party except an intended recipient.
In some embodiments, the step at 302 in Figure 3 can be extended to the following implementation, as shown in the process 400 in Figure 4.
At block 401, parameters are edited as basic parameters. The basic parameters are included in a parameter table 1.
At block 402, a set of asymmetric encryption key pairs is generated. “Asymmetric encryption” refers to an encryption method in which the encipher key and decipher key are different. The pair of asymmetric encryption keys includes a public key and a private key. The public key is preset into the software of the door entry device. The private key is stored properly. For example, the private key can be properly stored outside of the door entry device and on the user’s device.
At block 403, a digest 1 of the public key from the user is calculated. In some embodiments, the digest 1 can be generated by Hashing. “Hashing” refers to a process of applying a one-way hash function to the data, which is denoted by HASH (Data) . In some embodiments, the hash function includes a message digest five (MD5) hash function.
Digest 1 = HASH (public key from user)
At block 403, the digest 1 is used as a part of the parameters. In some embodiments, the digest 1 is included in the parameter table 1 to generate a new parameter table 2. The parameter table 2 includes the basic parameters (parameter table 1) and the digest 1.
At block 404, a digest 2 of the parameter table 2 is calculated. In some embodiments, the digest 2 can be generated by Hashing, which is denoted by HASH (Data) . In some embodiments, the hash function includes a message digest five (MD5) hash function.
Digest 2 = HASH (parameter table 2)
At block 404, the digest 2 is signed by the private key. “Signed/signing” refers to a process that is applied to the data to generate a verifiable form of a signature.
Signature 1 = SIGNED (privateKey, Digest 2)
“Signature” refers to a designator that can be verified to authenticate the originator and the integrity of the data. SIGNED (privateKey, Data) is the notation to denote the result of a signing process (the Data is signed by the privateKey) . The signature can be calculated using an asymmetric key digital signature algorithm. In some embodiments, signing the digest 2 is to calculate the hash of the digest 2, then calculate the signature from the hash using the asymmetric key algorithm, and append the signature to the digest 2. In this case, SIGNED (privateKey, Digest 2) includes the digest 2 and the signature attached. Alternatively, if the digest 2 is small enough, the signature may be directly calculated from the digest 2 instead of the hash of the digest 2. In this case, SIGNED (privateKey, Digest 2) may contain only the signature.
At block 405, the signature 1 is included in the parameter table 2 to generate a new parameter table 3. The parameter table 3 includes the basic parameters (parameter table 1) , the digest 1 and the signature 1. In some embodiments, the signature 1 can be added to the end of the parameter table 2.
In some embodiments, the step at 207 in Figure 3 can be extended to the following implementation, as shown in the process 500 in Figure 5.
At block 501, the door entry device collects the information code information and decodes it. Then, the door entry device firstly extracts the digest of the public key (the digest 1) . At the same time, the door entry device calculates the digest of public key stored by the door entry device itself.
Digest 1’ = HASH (public key from device)
Then, at block 502, the door entry device compares the digest 1 received from the information code and the digest 1’ calculated by itself. If they match (which means that the public key is veritable) , the verification is successful and the operation proceeds. If they do not match, the door entry device stops operation at block 503 and exits the information code scanning mode.
At block 504, the door entry device verifies the signature with the public key stored by the door entry device itself. “Signature Verification” is a reciprocal process for validating the signature produced by the signing process. At block 505, the door entry device determines whether the verification is successful. If the verification is successful, the operation proceeds. If the verification is failed, the door entry device stops operation at block 506 and exits the information code scanning mode.
At block 507, after the operation is finished, the door entry device saves and refreshes the parameters. The setting is finished and the door entry device exits the information code scanning mode. With the above features, the present invention can set door entry devices in a safe way.
If the private key is leaked, the legal user can regenerate a new key pair, add the public key of the new key pair to the door entry device by converting the public key into an information code in the form of parameters, and import it to the door entry device by the above-mentioned method to replace the old one. Subsequently, the parameter table is signed and verified by the new key pair.
Furthermore, in order to prevent illegal users from applying the information code of a specified device to other devices, it is a solution to use different key pairs for signature and verification for different devices.
In some embodiments, the UUID of the door entry device is included together with other parameters. And the UUID of the door entry device and the other parameters are calculated to generate a digest and signed. After the door entry device collects and decodes the information code, it firstly determines whether the UUID matches itself. If not, the door entry device stops the operation. In some embodiments, for a device with display, the UUID of the device can be displayed on the screen. In some embodiments, for a device without display, the UUID of the device can be printed out and used with the device.
Figure 6 schematically shows a door entry device according to some embodiments of the present disclosure. The door entry device 1 shown in Figure 6 includes several modules. In some embodiments, the door entry device 1 includes a camera module 10 and a button module 11. The camera module 10 is used to capture or scan an object for receiving input from another party. In some embodiments, the camera module 10 is used to scan an information code for receiving setting information from another part, for example, a cell phone of an operator, a user or an installer. The button module may include one or more buttons. For triggering the setting or for the initialization of the door entry device 1, some particular actions of a user on the button module 11 can be utilized. For example, a long press on the button module 11 can trigger the setting or the initialization of the door entry device. Alternatively, several consecutive short presses can trigger the setting or the initialization of the door entry device 1, for example, with two or more consecutive short presses. In other embodiments, any other appropriate actions can be used for triggering the setting or for the initialization of the door entry device. In some embodiments, the door entry device 1 also includes a first module 12 and a second module 13. The first module 12 may be means for obtaining at least one parameter for setting the door entry device by scanning an information code using a camera of the door entry device, the information code being converted from the at least one parameter determined by a user device for the door entry device. The second module 13 may be means for setting the door entry device based on the at least one parameter.

The method 700 may also include setting the door entry device based on the at least one parameter.
In some embodiments, the door entry device is installed outside of the building and at the entrance of a unit of a building. For the door entry device outdoor, the setting for such device is for setting the parameters for the unit of the building or for the building. In other embodiments, the door entry device can also be installed indoor and in each room. For the door entry device indoor, the setting for such device is for the setting the parameters for the room. In some embodiments, a parameter (value) can be associated with the authority of the user. After the door entry device obtain the parameter (value) regarding the authority of the user from the information code, the door entry device can determine whether the user has the authority to configure the building or to configure the room. In some embodiments, the setting for the building and the setting for the room can be performed at any door entry device outdoor and indoor, as long as the door entry device has a camera. The door entry device may determine the authority of the user from the information code first and perform the operation after determining the authority of the user.
