Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

However, if the daughter board is replaced or maliciously modified, the above method cannot enable the user to perceive the change of the daughter board in time, which may still easily lead to leakage of the user's printed information.

Based on the above technical problems, the present invention provides a method and device for prompting security information. After the image forming apparatus is powered on, the main control board first authenticates each sub-board inside the image forming apparatus. If the image forming apparatus has an authentication failure The main control board controls the output of the prompt information, so that the user can timely perceive that there is a daughter board with a leakage risk in the image forming apparatus, and further confirm the daughter board with a leakage risk, ensuring that Security of User Information.

FIG. 1 is a schematic diagram of an optional image forming apparatus provided by the present invention. The security information prompting method provided by the present invention can be applied to the image forming apparatus shown in FIG. 1 , and the image forming apparatus shown in FIG. 1 includes a main board card and a daughter board card. The main board is a data control board, and the daughter board includes a scan control board, a user interface UI control board, an engine control board, and a fax control board.

It should be noted that the number and type of the daughter boards in FIG. 1 are only an illustration, and the daughter boards in the image forming apparatus may also be any combination of one or more of the daughter boards shown in FIG. 1 . The number and type of daughter boards shown in Figure 1 are not limited.

In Figure 1, the data control board can transmit instructions to each daughter board through the command interface, and transmit image information to the scanning control board and the engine control board respectively through the image interface. The method and current method of data transmission between the data control board and each daughter board Similar to the prior art, the present invention will not repeat them here.

The security information prompting method provided by the present invention will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 2 is a schematic flowchart of Embodiment 1 of the security information prompting method provided by the present invention. As shown in Figure 2, the security information prompting method provided by the present invention includes:

S201. After the image forming apparatus is powered on, the main control board authenticates each sub-board inside the image forming apparatus.

The image forming apparatus is powered on means that the power switch of the image forming apparatus is turned on, and the image forming apparatus has power supply.

The daughter board card inside the image forming apparatus includes at least one of a scan control board, a user interface UI control board, an engine control board and a fax control board. That is, according to the function or design requirements of the image forming apparatus itself, the sub-cards inside the image forming apparatus may have only any one of the sub-boards, or may include more than two sub-boards at the same time.

For example, the daughter board inside the image forming apparatus may include any one of the above control boards, for example, the daughter board inside the image forming apparatus only includes the scanning control board; the daughter board inside the image forming apparatus only includes the user interface UI control board board; the daughter board inside the image forming apparatus includes only the engine control board; the daughter board inside the image forming apparatus only includes the facsimile control board.

The daughter board inside the image forming apparatus may include a combination of two or more control boards in the above-mentioned control boards. For example, the daughter board inside the image forming apparatus includes: a scan control board, a user interface UI control board, an engine control board, and a fax control board The daughter board inside the image forming apparatus includes: a scan control board, a user interface UI control board and a fax control board; the daughter board inside the image forming apparatus includes: a scanning control board and a user interface UI control board. Other combinations are not repeated here.

Taking the daughter board inside the image forming apparatus only including the scanning control board as an example, the main board card authenticates the scanning control board after the image forming apparatus is powered on, and then determines whether to execute the step S202 according to the authentication result. The authentication process in which there is only one daughter board inside the image forming apparatus is similar to that in this example, and will not be repeated in the present invention.

In addition, it should be noted that when the image forming apparatus includes a plurality of daughter boards, it is not strictly required that each daughter board is an independent circuit board. The above startup control method needs to be performed on the daughter board corresponding to each functional module, and a verification can also be performed. For example, if a separate circuit board is provided with a daughter board corresponding to the scan control function module and a daughter board corresponding to the user interface UI control function module, the main control board can perform the scan function module, The user interface UI function modules are verified separately; it is also possible to perform verification only on this single circuit board; specifically, it can be confirmed according to the actual application, for example, when the modules on this single circuit board that may involve security issues are shared For example, if the scan control function and the UI control function share a memory, only one security verification can be performed. If even if a circuit board is shared on the hardware, the involved security control modules are completely independent and need to be verified separately.

Taking the daughter boards inside the image forming apparatus including: the scanning control board, the user interface UI control board and the fax control board as an example, after the main board is powered on the image forming apparatus, the three daughter boards are authenticated in a certain order. Whether to execute the step of S202 is determined according to the authentication result of each sub-board. The daughter board inside the image forming apparatus includes two or more authentication processes, which is similar to this example, and will not be repeated here in the present invention.

Optionally, each sub-board stores corresponding sub-board information, and the sub-board information includes: sub-board type, sub-board serial number, sub-board hardware version number and sub-board firmware version number. The main control board can authenticate each daughter board according to the daughter board information read from each daughter board.

S202 , if there is a daughter board card that fails the authentication in the image forming apparatus, the main control board card controls to output a prompt message.

Specifically, in S201, there are two results in the authentication of the main control board to the daughter board. One is that all the daughter boards in the image forming apparatus have passed the authentication, and the other is that there are daughter boards in the image forming apparatus that have not passed the authentication. Card. When the authentication result of S201 is the second type, the main control board controls the output prompt information. The user can timely perceive that there is a daughter board with a risk of leakage in the image forming apparatus, thereby ensuring the security of user information.

A specific implementation method for the data control board to detect the existence of the scanning control board may be: the data control board sequentially follows the communication mode (communication type, such as SPI, UART, IIC, etc.) and communication format (command format) of each daughter board. , send a communication command to each daughter board, and wait for the communication response from the daughter board; if the daughter board does not respond to the sent communication command normally within a predetermined time; then it is determined that the daughter board is not installed or not installed in place ( That is, it does not exist); if it can correctly respond to the communication command within a predetermined time, it is considered that the daughter board exists.

Further preferably, if each daughter board inside the image forming apparatus passes the authentication, the main control board controls the image forming apparatus to start up: that is, if each daughter board inside the image forming apparatus is authenticated If passed, the main control board determines that the daughter boards in the image forming apparatus meet the security requirements and can execute subsequent job processing; the “startup” mentioned in this implementation means that each daughter board in the image forming apparatus can control the The corresponding electromechanical execution unit enters the normal working state.

In the security information prompting method provided in this embodiment, after the image forming apparatus is powered on, the main control board first authenticates each sub-board in the image forming apparatus. The main control board controls the output prompt information, so that the user can timely perceive that there is a daughter board with a risk of leakage in the image forming apparatus, and the security of the user information is ensured.

The process of authenticating the daughter board by the main control board according to the daughter board information and the process of controlling the output of prompt information in the above embodiment will be described in detail below.

FIG. 3 is a schematic flowchart of Embodiment 2 of the security information prompting method provided by the present invention. As shown in FIG. 3 , the security information prompting method provided by this embodiment includes:

The specific content of each step is introduced, and the following description is made: The following S301-S303 are the authentication process for any sub-board in the image forming apparatus. For the convenience of description, the following steps use the current sub-board to represent any of the above sub-boards. Board card, it should be noted that when there are more than two daughter boards in the image forming apparatus, all daughter boards in the image forming apparatus can be authenticated by means of S301-S303. The specific content of each step is described below. introduce.

S301, the main control board reads the daughter board information from the current daughter board.

S302, the main control board determines whether the current daughter board is legal according to the daughter board information.

Among them, the main control board can judge whether the current daughter board is legal or not as follows:

The main control board compares the daughter board serial number of the current daughter board with the serial number stored in the illegal daughter board information library. If the illegal daughter board information library does not have the daughter board serial number of the current daughter board, The current daughter board is judged to be legal; if the daughter board serial number of the current daughter board exists in the illegal daughter board information database, the current daughter board is judged to be invalid.

The serial number stored in the illegal daughter board information library is the serial number of the daughter board that does not match the image forming apparatus or that has a risk of information leakage.

S303 , according to the judgment result, determine whether the current daughter board has passed the authentication.

Specifically, when the judgment result of S302 is legal, it is determined that the authentication of the current daughter board is passed; when the judgment result of S302 is invalid, it is determined that the authentication of the current daughter board has not passed.

The process of the above S301-S303 is described below by taking an example:

After the image forming apparatus is powered on, the main control board authenticates the daughter boards inside the image forming apparatus in turn. Assuming that the daughter board to be authenticated is the UI control board, the main control board reads the daughter board of the UI control board. card information, and then compare the serial number of the daughter board of the UI control board with the serial number stored in the illegal daughter board information library. If the illegal daughter board information library has the daughter board serial number of the UI control board, it indicates The UI control board is illegal, based on this, the main control board can determine that the UI control board has not passed the authentication; if there is no daughter board serial number of the UI control board in the illegal daughter board information database, it indicates that the UI control board has not passed the authentication. Legal, based on this, the main control board can determine that the UI control board has passed the authentication. Using the same method to authenticate other daughter boards, the authentication results of all daughter boards can be obtained.

S304. If the image forming apparatus has a daughter board card that has not passed the authentication, the main control board card controls to output illegal prompt information, where the illegal prompt information is used to prompt that there is an illegal daughter board in the image forming apparatus, The illegal prompt information includes the type of the illegal daughter board.

Specifically, there are two results in the authentication of S301-S303. One is that all the daughter cards in the image forming apparatus have passed the authentication, that is, all the daughter cards in the image forming apparatus are legal; A daughter board that has not passed the authentication, that is, an illegal daughter board exists inside the image forming apparatus.

When the authentication of S301-S303 is the second result, the main control board controls to output illegal prompt information, and the illegal prompt information is used to prompt that there is an illegal daughter board in the image forming apparatus, and the illegal prompt information includes the illegal daughter board. Type of board.

Corresponding to the example in 303, assuming that the authentication result of the main control board to the daughter board inside the image forming apparatus is that the UI control board fails the authentication, and all other daughter boards pass the authentication, then the main control board can control the output as shown in the figure. 4 shows the illegal prompt information. The user can know that the UI control board in the image forming apparatus is an illegal daughter board through the illegal prompt information, and the user can replace the illegal daughter board in time to avoid leakage of user information caused by the illegal daughter board.

It should be noted that the above example is based on the failure of UI control board authentication. It is possible that there are multiple sub-boards that have failed the authentication. In this case, the main board will control and output the sub-boards that have not passed the authentication. The illegal prompt information of the card, the form of the illegal prompt information of the plurality of sub-board cards is similar to that in FIG.

Optionally, the above illegal prompt information may be displayed to the user through the panel of the image forming apparatus, voice broadcast, and flashing lights. After the user receives the illegal prompt information, the illegal sub-card board can be replaced in time, thereby preventing the leakage of user information.

The security information prompting method provided in this embodiment describes an achievable authentication method for the main control board to the daughter board. There is an illegal daughter board inside the image forming device. At this time, the main control board controls the output of illegal prompt information. The user can know which daughter board is illegal through the illegal prompt information, which is convenient for the user to replace the illegal daughter board in time. The leakage of user information is prevented.

Optionally, before the main control board authenticates each sub-board, it may first detect whether each sub-board exists, and if it exists, perform the authentication process on the corresponding sub-board. FIG. 5 is a schematic flowchart of Embodiment 3 of the security information prompting method provided by the present invention. As shown in FIG. 5 , the security information prompting method provided by this embodiment includes:

The specific content of each step is described as follows: The following S501-S505 are the detection and authentication process for any sub-board in the image forming apparatus. For the convenience of description, the following steps use the current sub-board to represent the above-mentioned any sub-board. One daughter board. It should be noted that when there are more than two daughter boards in the image forming apparatus, all daughter boards in the image forming apparatus can be detected and authenticated by means of S501-S505. Each step is described below. The specific content is introduced.

S501. After the image forming apparatus is powered on, the main control board detects whether the current daughter board exists.

If it exists, execute S502;

If it does not exist, the main control board will control and output the not-installed prompt information, the non-installed prompt information is used to prompt that there is an un-installed daughter board in the image forming apparatus, and the un-installed prompt information includes the un-installed daughter board Category of the card.

Optionally, the above non-installation prompt information can be output immediately when it is detected that the current daughter board does not exist, or it can be unified with the prompt information of other abnormal daughter boards after the detection and authentication process of other daughter boards is completed. output.

For example, after the image forming apparatus is powered on, the main control board checks and authenticates the daughter boards inside the image forming apparatus in turn. Assuming that the daughter board to be tested is the UI control board, the UI control board is detected and verified. If it does not exist, the main control board can control to output the prompt message of not being installed as shown in Figure 6. The user can know that the UI control board is not installed in the image forming apparatus through the prompt message of not being installed. The user can install the UI control board in time to The image forming apparatus can be used normally.

Optionally, the above-mentioned not-installed prompt information may be displayed to the user through the panel of the image forming apparatus, voice broadcast, and flashing lights. After receiving the not-installed prompt message, the user can install the corresponding daughter board in time, so that the image forming apparatus can be used normally.

S502, the main control board reads the daughter board information from the current daughter board.

S503, the main control board determines whether the current daughter board is legal according to the daughter board information.

Wherein, the prompt scheme when the judgment result of S503 is invalid may refer to the above-mentioned embodiment, which will not be repeated in the present invention; if the judgment result of S503 is valid, S504 is further executed.

S504, the main control board performs digital verification on the current daughter board according to the daughter board information.

Among them, the achievable ways for the main control board to perform digital verification on the current daughter board include:

The main control board retrieves the digital signature value corresponding to the category of the current sub-board in the authentication sub-board information library according to the category of the current sub-board, and the main control board adopts a preset signature algorithm for the current sub-board. The information is digitally signed, and the current signature value is obtained, and the current signature value is compared with the retrieved digital signature value. If the comparison is successful, it indicates that the current daughter board is the original game daughter board, and the verification of the current daughter board is successful. ; If the comparison is not successful, it indicates that the current daughter board is not the original game daughter board, and the verification of the current daughter board is unsuccessful.

S505 , according to the verification result, determine whether the current daughter board has passed the verification.

Specifically, when the verification result of S504 is successful, it is determined that the authentication of the current daughter board has passed; when the verification result of S504 is unsuccessful, it is determined that the current daughter board has not passed the authentication.

The process of the above S502-S505 is described below with an example:

After the image forming apparatus is powered on, the main control board sequentially detects and authenticates the daughter boards inside the image forming apparatus. If the UI control board is detected, the UI control board is further authenticated, and the main control board reads The daughter board information of the UI control board, and then judge whether the UI control board is legal according to the serial number of the daughter board of the UI control board. If it is legal, further digitally verify the UI control board according to the daughter board information. If the verification is successful, the main control board can use this as a basis to determine that the UI control board has passed the authentication; if the verification fails, the main control board can use this as a basis to determine that the UI control board has not passed the authentication. Use the same method to authenticate other daughter boards to obtain the authentication results of all daughter boards.

S506. If the image forming apparatus has a daughter board card that has not passed the authentication, the main control board outputs unauthenticated prompt information through the display panel of the image forming apparatus, where the unauthenticated prompt information is used to instruct the image forming apparatus An unauthenticated daughter card exists in the memory, and the unauthenticated prompt information includes the category of the unauthenticated daughter card and processing options for the user to select.

Specifically, there are two results in the authentication of S502-S505. One is that all daughter cards in the image forming apparatus have passed the authentication, that is, all daughter cards in the image forming apparatus are authenticated daughter cards; the other is that the image forming apparatus has passed the authentication. There is a sub-board that has not passed the authentication in the forming apparatus, that is, there is an unauthenticated sub-board in the image forming apparatus.

When the authentication of S502-S505 is the second result, the main control board controls to output unauthenticated prompt information, where the unauthenticated prompt information is used to prompt that an unauthenticated daughter board exists in the image forming apparatus, and the unauthenticated prompt information includes The category of the unauthenticated daughter board and the processing options for the user to select.

Corresponding to the example in S505, assuming that the authentication result of the main control board on the daughter board inside the image forming apparatus is that the UI control board has not passed the authentication, and all other daughter boards have passed the authentication, the main control board can control the output as shown in the figure. 7 shows the unauthenticated prompt message. The user can know that the UI control board in the image forming apparatus is an unauthenticated daughter board through the unauthenticated prompt information. If the unauthenticated daughter board is an upgrade of the original configuration board, the user can ensure the safety of the daughter board. Then you can select the Continue option in Figure 7. If the user cannot guarantee the safety of the above UI control panel, the cancel option in FIG. 7 can be selected.
