Detailed Description
In order to make the objects, 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 drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Nowadays, smart home devices have become direction indicators of the industry, and smart home systems composed of smart home devices also come into play, and a smart home system is generally composed of a control device, a server and a terminal device, wherein the terminal device may be a smart air conditioner, a smart television, a smart lamp, and other smart devices, the effective control of the terminal device by the control device is the basis for establishing the smart home system, the control device needs to forward a control instruction through the server when issuing the control instruction to the terminal device, the server needs to analyze the control instruction in the process of forwarding the control instruction, and the server is likely to be invaded by other devices in the series of working processes of analyzing the control instruction, and the invasion of other devices is likely to cause the control instruction to be tampered, thereby generating harmful instructions unfavorable to the terminal device, therefore, when the server forwards the control instruction to the terminal device, it is necessary to filter and intercept the control instruction.
The embodiment of the invention provides an information screening method, which can screen a control command before sending the control command to a terminal device, remove harmful commands (such as commands causing large increase of power, large increase of temperature or accidental closing of the terminal device) and ensure the safety of the terminal device.
Fig. 1 is a flowchart of an information screening method according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
s11, receiving control information sent by first equipment, wherein the destination address of the control information is second equipment.
The control information may be information such as a control instruction, a command, and the like, where the destination address of the control information is that the control information is to be sent to the second device to control the second device, and taking the control information as a control instruction, that is, the control instruction is an instruction for controlling the second device as an example.
In a possible implementation manner, the first device may be a server, the second device is a terminal device, the control information is a control instruction sent by the server for controlling the terminal device, and the control instruction may be obtained by analyzing a control intention sent by the server to the control device.
In a possible implementation manner, the first device may be a control device, the second device may be a server or a server cluster, and the control information is a control instruction sent by the control device to control the server or the server cluster.
And S12, matching the control information with preset danger information.
The preset danger information is control information which is preset according to requirements and can have adverse effects on the second equipment, for example: the dangerous information may be a control instruction for tampering or deleting data, sending such control information to the second device may cause data of the second device to be tampered, so that the second device cannot operate normally, and the dangerous information may also be control information that may cause the second device to operate at an excessively high power and an excessively high temperature, and such control information controls the second device to operate, so that the second device is excessively worn, so that the service life is shortened.
In one possible implementation, the hazard information may be determined by:
step 1: historical control information received by second equipment and historical operation information of the second equipment corresponding to the historical control information are obtained.
The operation information corresponding to the historical control information is the operation parameter information (such as power, temperature, etc.) of the second device after receiving the historical control information.
The historical control information and the historical operation information are obtained for analyzing how the second device operates under different control information, and determining a control command that has a bad influence on the second device (e.g., causes an over-power condition, an over-temperature condition, etc.).
Step 2: and matching the historical operation information with the operation information of the second equipment in a normal operation state.
The operation information of the second device in the normal operation state may be obtained through a historical operation record of the second device, and specifically may include a power threshold, a temperature threshold, operation data, and the like of the second device in the normal operation state.
When the historical operation information is matched with the operation information when the second equipment is in the normal operation state, the second equipment is in the normal operation state at the moment corresponding to the historical operation information, and meanwhile, the historical control information corresponding to the historical operation information is harmless to the second equipment, otherwise, the second equipment is in the abnormal operation state at the moment corresponding to the historical operation information, and the historical control information corresponding to the historical operation information is harmful to the second equipment and can generate adverse effects on the second equipment, so that the second equipment is abnormal in operation.
And step 3: and determining historical control information corresponding to historical operation information which is not matched with the operation information of the second equipment in the normal operation state as preset dangerous information.
The present embodiment aims to determine dangerous information that adversely affects the second device, and therefore historical control information corresponding to historical operation information that does not match the operation information of the second device in the normal operation state (for example, historical operation information that power does not match power of the second device in the normal operation state, and temperature does not match temperature of the second device in the normal operation state) may be determined as the preset dangerous information.
And S13, if the matching is unsuccessful, the control information is sent to second equipment.
Since the preset danger information is control information having a bad influence on the second device, when the received information is unsuccessfully matched with the preset danger information, it is indicated that the received control information is not control information having a bad influence on the second device, that is, control information having no bad influence on the second device, and therefore, the received control information can be sent to the second device at this time.
On the contrary, if the received control information is successfully matched with the preset dangerous information, the received control information is the control information which has bad influence on the second equipment, the received control information is intercepted and not sent to the second equipment, so that the bad influence on the second equipment is avoided.
In the information screening method provided by the embodiment of the invention, before the control information sent by the first device is sent to the second device, the control information is matched with the preset danger information, so that the control information successfully matched with the preset danger information is screened out, and only the control information not matched with the preset danger information is sent to the second device. In a specific application, the preset dangerous information is control information which has bad influence on the second equipment, for example, the control information which can cause data loss or tampering of the second equipment, or the control information which can cause the loss of the second equipment to be larger, and the like.
In a possible embodiment, the information screening method provided in the embodiment of the present invention further includes, in addition to the above steps:
and if the received control information sent by the first equipment is successfully matched with the preset danger information, generating early warning information.
The early warning information can be a control instruction for controlling the alarm to sound, a control instruction for controlling the alarm indicator lamp to be on and/or generated voice/text prompt information and the like.
When the received control information is successfully matched with the preset dangerous information, the received control information is harmful control information which has bad influence on the second equipment, and when the harmful control information is found, early warning can be timely carried out to control the harmful control information, so that the source of the harmful control information can be further timely tracked, the harmful control information can be timely eliminated, and the protection of the second equipment is further promoted.
In a possible embodiment, because the same control information may have different effects at different times, for example, the control information of the shutdown instruction, in a case that the user wants to shutdown, the effect of the shutdown instruction is positive, for example, when the user wants to shutdown, the second device is controlled to shutdown through the shutdown instruction, so that the electric energy can be saved, but in a case that the user does not want to shutdown, the shutdown instruction may cause the second device to fail to operate normally, and even cause the paralysis of the system where the entire second device is located, for example, taking the server in the smart home system as the second device as an example, if the server is shutdown without preparation, the entire smart home system may be paralyzed, and thus it can be known that in a case that the user does not want to shutdown, the shutdown of the second device will produce a negative effect due to the receipt of the shutdown instruction, therefore, in order to prevent this situation from occurring, when such control information is really needed to control the second device, the control information is sent in an encrypted manner, so that as long as the received control information can be correctly decrypted, it is indicated that the control information is sent to the second device directly under the condition that the user wishes, and in this case, the information screening method provided by the embodiment of the present invention further includes:
before matching received control information sent by first equipment with preset danger information, judging whether the received control information needs to be decrypted or not; if the decryption is not needed, executing a step of matching the control information with preset danger information; and if the decryption is required, decrypting the control information, and if the decryption is successful, sending the control information to the second equipment.
