Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
The embodiment of the application provides a method for preventing collection of effective information, wherein a forged probe frame and a corresponding wireless signal are generated, interference information is added to information collected by a collection terminal, and the collection terminal is prevented from collecting effective information.
Example one
Fig. 1 is a flowchart of a method for preventing collection of valid information according to an embodiment, where the method may be applied to a gateway device such as a wireless router, or may be applied to an electronic device that only transmits wireless signals. As shown in fig. 1, the method provided by the present embodiment includes steps S101-S103.
S101: a first MAC address is selected.
When the wireless router works, the first MAC address is selected according to a preset rule. The first MAC address is not an MAC address which is burned in hardware when the wireless router leaves a factory and identifies the information of the wireless router, but is a MAC address which represents a Station (STA) and is constructed randomly; the first MAC address may be MAC addresses of various possible user terminals, for example, MAC addresses collected by a smart phone, or MAC addresses for a notebook computer.
It should be noted that selecting the first MAC address does not represent that the first MAC address is already stored in the wireless router; in practical application, the router may store selectable MAC address field information, and select a first MAC address in the MAC address field; in practical applications, the first MAC address is preferably selected in a random manner.
S102: a probe frame is generated.
The wireless router generates a probe frame according to a rule protocol; wherein the source address of the probe frame is the first MAC address.
The probe frame is a data frame sent by the Wireless user terminal and including a source MAC address, and is mainly used for notifying a surrounding Wireless Access Point (AP) that the AP may have a connection requirement. Taking the wifi protocol adopted by the wireless router as an example, the wireless router generates a Probe Request frame, and the Probe Request frame includes the first MAC address and also includes identification information of the Probe Request frame.
S103: the wireless transmitter is controlled to transmit a wireless signal including information of the probe frame.
After generating the probe frame, a wireless transmitter in the wireless router modulates the probe frame to generate a wireless signal and radiates the wireless signal to the environment. If the coverage range of the wireless signal is internally provided with the collecting equipment; after the wireless signal is received and processed by the signal receiver of such a device, the first MAC address is stored as the MAC address of a real user terminal.
If the wireless router randomly constructs a large number of first MAC addresses and generates corresponding wireless signals comprising probe frame information; these wireless signals are collected by the collecting device to form a large amount of fictitious terminal information, and the fictitious terminal information and the real terminal information are mixed, so that the collecting device or the subsequent data processing device cannot or is difficult to determine the number of the real terminals, and the number of users in the area is difficult to detect.
Example two
Fig. 2 is a flowchart of a method for preventing the collection of valid information according to the second embodiment. As shown in fig. 2, the method provided by the present embodiment includes steps S201 to S205.
Before describing the method of the present embodiment, a description will be given to possible implementation scenarios of the method. It is still exemplified herein that the user terminals (i.e., stations), wireless routers, and collection devices communicate using the WIFI protocol.
When the WIFI equipment of the user terminal is in an open state, if a specific wireless network access point is not connected, Probe Request frames and corresponding wireless signals are generated at intervals so as to inform surrounding WIFI equipment that the connection requirement is possible.
If the user terminal is in a mobile state (that is, the user carrying the user terminal is in a mobile state), and the wireless router and the collecting device are fixed in position, the signal strength of the Probe Request frame sent by the same device collected by the wireless router and the collecting device at different moments is different, and the collected signal strength shows a specific rule along with the change of the mobile position of the user terminal.
If the wireless router transmits the wireless signals including the first MAC address according to the same transmission power or the power without specific rules all the time, the collection equipment collects the wireless signals for a long time, and the first MAC address can be judged to be the MAC address of the false terminal by comparing the signal intensity corresponding to the first MAC address; after determining that the first MAC address is the MAC address of the false terminal, the collecting device may discard the MAC address, and store the MAC address whose signal strength changes according to a specific rule as the MAC address of the real terminal.
S201: a first MAC address is selected.
When the wireless router works, the first MAC address is selected according to a preset rule. It should be noted that the first MAC address is not a MAC address which is burned in hardware when the wireless router leaves the factory and identifies the information of the wireless router itself, but is a MAC address which represents a Station (STA) and is constructed randomly; the first MAC address may be a MAC address of various possible user terminals, for example, a MAC address for smart collection, or a MAC address for a notebook computer;
selecting the first MAC address does not represent that the wireless router already stores the first MAC address; in practical application, the router may store selectable MAC address field information, and select a first MAC address in the MAC address field; in practical applications, the first MAC address is preferably selected in a random manner.
S202: and planning the sequentially passed virtual position points.
In this embodiment, a virtual user terminal identified by the first MAC needs to be constructed; the virtual location points are a plurality of location points on a virtual path that the virtual user terminal passes through.
S203: and determining the transmitting power corresponding to the virtual position point.
The transmission power described herein does not refer to the transmission power transmitted by the virtual ue, but the corresponding transmission power when the wireless router transmits the wireless signal.
Fig. 3 is a schematic diagram of a principle method of implementation of determining the transmission power corresponding to a virtual location point. As shown in fig. 3. The dotted line is a virtual path of the set virtual user terminal passing through the field area, and a plurality of position points are selected as virtual position points on the virtual path.
As shown in fig. 3, the virtual location points, the wireless router and the collection device form a triangle (or are on the same straight line), because the length of one side of the triangle is determined (the distance from the wireless router to the collection device is determined), the distance change from different virtual location points to the wireless router and the distance from the virtual location point to the corresponding collection device present a certain correlation. Correspondingly, the signal strength of the Probe Request frames sent by the real user terminals at different virtual location points, which are collected by the wireless router and the collecting device, are in a correlated relationship. Correspondingly, if the wireless router is used for transmitting false Probe Request frames, the required transmission power can be determined according to the distance from the wireless router to the virtual location points, so that the signal strength of the wireless signals including the Probe Request frames received by the receiving equipment presents the signal strength change characteristics of the Probe Request frames transmitted by the real user terminal through the virtual location points.
In the embodiment of the application, the transmitting power corresponding to each virtual position point is determined according to the distance from the virtual position point to the wireless transmitter, and the transmitting power and the distance from the virtual position point to the wireless transmitter are in an inverse correlation relationship.
S204: a probe frame is generated.
The wireless router generates a Probe request frame (Probe frame) according to a WIFI rule protocol; wherein the source address of the probe frame is the first MAC address.
S205: and controlling the wireless transmitter to transmit wireless signals according to the preset frequency and the corresponding transmission power according to the sequence of the virtual position points.
After the wireless router transmits wireless signals according to the preset transmitting frequency, the wireless signals are sequentially received by the receiving equipment; because the power of the wireless signals sent at different times is different, after the wireless signals at different times are received by the receiving device, the signal strength determined by the receiving device is different, and the positions of the virtual user terminals determined in sequence are different. Because the signal strength change of each wireless signal received by the receiving device is associated with the position sequence of the set virtual position point, the wireless device cannot determine whether the corresponding wireless signal is a wireless signal sent by a real user terminal or a wireless signal sent by a false user terminal through analysis of the signal strength change, and thus cannot identify whether the user information identified according to each wireless signal is false information.
According to the foregoing analysis, in the embodiment of the present application, a passing virtual location point is planned first, a corresponding transmission power is determined according to the planned virtual location point, and wireless signals including the first MAC address are sequentially transmitted according to the virtual location point and the corresponding transmission power, so that the strength characteristics of each wireless signal received by the receiving device are similar to the strength characteristics of a wireless signal transmitted when a real mobile terminal moves, and therefore, a user terminal cannot identify whether the mobile terminal is a real mobile terminal according to the signal strength, and cannot collect effective information.
It should be noted that there is no direct correlation between the planning of sequentially passing virtual location points, the determination of the corresponding generation power and the selection of the first MAC address, so in other embodiments, the sequentially passing virtual location points and the corresponding transmission power may be planned first, and then the first MAC address may be selected, that is, the foregoing S201 may be placed after S203.
In the method for preventing the collection of the effective information, the wireless router stores the probe frame after generating the probe frame, and transmits the wireless signal including the information of the probe frame according to the preset frequency and the transmission power; in other embodiments, the probe frame may also be generated according to a preset frequency, and then the wireless transmitter is controlled to transmit the wireless signal including the probe frame information according to the corresponding transmission power according to the order of the virtual location points; that is, the wireless router does not store the probe frame but generates the probe frame at any time.
According to the usage rule of the MAC address, the IEEE allocates MAC addresses of different sections to different device manufacturers, and the MAC addresses allocated by different device manufacturers can be queried. If the first MAC address is set as a MAC address used by the non-local area and the non-utilization device, the collection device can quickly determine the corresponding wireless signal as an interference signal sent by the false terminal through the first MAC address, and can discard the information corresponding to the first MAC address.
To avoid the problems in the previous paragraph, in the embodiment of the present application, the selection of the first MAC address may be optimized as follows: selecting a first MAC address in a preset MAC address field; among them, the preset MAC address field is an address field assigned to a specific device manufacturer, and devices produced by the specific device manufacturer are largely used in the collection area of the collection device. Therefore, because the corresponding wireless signal cannot be identified as the signal sent by the false user terminal through the first MAC address, whether the information in the wireless signal is real information or false information cannot be identified.
Furthermore, different probe frame frequencies may be set by terminal devices produced by different device manufacturers, and in order to avoid the collecting device determining that the terminal device is a signal sent by a false ue according to the frequency of the received wireless signal and the corresponding first AMC address, the aforementioned preset frequency may be set as the probe frame frequency of the real terminal corresponding to the preset MAC address field, that is, the probe frame frequency of the ue produced by a specific device manufacturer.
Further, the planning of the sequentially passing virtual location points includes: setting a moving speed, and planning sequentially passing virtual position points according to a preset frequency segment and the moving speed; it should be noted that the aforementioned moving speed may be a fixed speed or a variable speed; in a specific application, the moving speed is preferably set to a speed that changes randomly within a certain interval, so as to simulate the movement of a user carrying a real user terminal as much as possible.
Further, planning a virtual location point may require consideration of environmental conditions in addition to the moving speed and the preset frequency. Taking the method provided by the embodiment as an example, if a pond is arranged in the park, the real user terminal cannot pass through the pond, and therefore it is necessary to avoid the virtual location point from being arranged in the area corresponding to the pond.
It should also be noted that, in practical applications, the path formed by the collecting device according to the collected wireless signals may systematically deviate from the path formed by the real user terminal when it passes through the real environment; for example: in the park scene, the path determined by the collecting device according to the wireless signal sent by the real user terminal does not pass through the pond, and the path determined according to the wireless signal sent by the false user terminal passes through the pond. In order to avoid that the collecting device determines false information by using systematic deviations, systematic errors can also be corrected by pre-testing, i.e. the position of the virtual location point is corrected.
It should be noted that in the implementation of the present application, the number of the wireless transmitters of the wireless router may be one, or may be multiple. In the case that the number of the wireless transmitters is one, the determination of the transmission power corresponding to the virtual position point is directly based on the distance between the virtual position point and the wireless transmitter. In the case where the number of wireless transmitters is plural, the transmission power may be determined according to the distance from the virtual location point to the nearest wireless transmitter.
EXAMPLE III
Fig. 4 is a flowchart of a method for preventing the collection of valid information according to the third embodiment. As shown in FIG. 4, the method provided by the present embodiment includes steps S301-S304
S301: a first MAC address is selected.
S302: planning a virtual location point to be passed through.
The principle of planning virtual location points in this embodiment is similar to that in the second embodiment, and will not be repeated here. However, unlike the second embodiment, in the present embodiment, all virtual location points simulating the movement of the real mobile terminal are not planned in advance, but only the virtual location points to be passed through are planned.
S303: and determining the transmitting power corresponding to the virtual position point.
The transmission power described herein does not refer to the transmission power transmitted by the virtual ue, but the corresponding transmission power when the wireless router transmits the wireless signal.
As shown in fig. 3. The dotted line is a virtual path of the set virtual user terminal passing through the field area, and a plurality of position points are selected as virtual position points on the virtual path.
As shown in fig. 3, the virtual location points, the wireless router and the collection device form a triangle (or are on the same straight line), because the length of one side of the triangle is determined (the distance from the wireless router to the collection device is determined), the distance change from different virtual location points to the wireless router and the distance from the virtual location point to the corresponding collection device present a certain correlation. Correspondingly, the signal strength of the Probe Request frames sent by the real user terminals at different virtual location points, which are collected by the wireless router and the collecting device, are in a correlated relationship. Correspondingly, if the wireless router is used for transmitting false Probe Request frames, the required transmission power can be determined according to the distance from the wireless router to the virtual location points, so that the signal strength of the wireless signals including the Probe Request frames received by the receiving equipment presents the signal strength change characteristics of the Probe Request frames transmitted by the real user terminal through the virtual location points.
In the embodiment of the application, the transmitting power corresponding to each virtual position point is determined according to the distance from the virtual position point to the wireless transmitter, and the transmitting power and the distance from the virtual position point to the wireless transmitter are in an inverse correlation relationship.
S304: generating a probe frame, and controlling a wireless transmitter to transmit a wireless signal according to the transmission power; subsequently, execution continues with S302, or ends.
In the method for preventing collecting valid information provided in this embodiment, all virtual location points on a virtual path, such as that shown in fig. 3, are not planned at one time, but only one virtual location point is planned, and after a wireless signal is transmitted according to the corresponding power of the virtual location point, the next virtual location point and the corresponding transmission power are planned.
After the wireless router transmits wireless signals according to the preset transmitting frequency, the wireless signals are sequentially received by the receiving equipment; because the power of the wireless signals sent at different times is different, after the wireless signals at different times are received by the receiving device, the signal strength determined by the receiving device is different, and the positions of the virtual user terminals determined in sequence are different. Because the signal strength change of each wireless signal received by the receiving device is associated with the position sequence of the set virtual position point, the wireless device cannot determine whether the corresponding wireless signal is a wireless signal sent by a real user terminal or a wireless signal sent by a false user terminal through analysis of the signal strength change, and thus cannot identify whether the user information identified according to each wireless signal is false information.
According to the foregoing analysis, in the embodiment of the present application, a passing virtual location point is planned first, a corresponding transmission power is determined according to the planned virtual location point, and wireless signals including the first MAC address are sequentially transmitted according to the virtual location point and the corresponding transmission power, so that the strength characteristics of each wireless signal received by the receiving device are similar to the strength characteristics of a wireless signal transmitted when a real mobile terminal moves, and therefore, a user terminal cannot identify whether the mobile terminal is a real mobile terminal according to the signal strength, and cannot collect effective information.
According to the usage rule of the MAC address, the IEEE allocates MAC addresses of different sections to different device manufacturers, and the MAC addresses allocated by different device manufacturers can be queried. If the first MAC address is set as a MAC address used by the non-local area and the non-utilization device, the collection device can quickly determine the corresponding wireless signal as an interference signal sent by the false terminal through the first MAC address, and can discard the information corresponding to the first MAC address.
To avoid the problems in the previous paragraph, in the embodiment of the present application, the selection of the first MAC address may be optimized as follows: selecting a first MAC address in a preset MAC address field; among them, the preset MAC address field is an address field assigned to a specific device manufacturer, and devices produced by the specific device manufacturer are largely used in the collection area of the collection device. Therefore, because the corresponding wireless signal cannot be identified as the signal sent by the false user terminal through the first MAC address, whether the information in the wireless signal is real information or false information cannot be identified.
Furthermore, different probe frame frequencies may be set by terminal devices produced by different device manufacturers, and in order to avoid the collecting device determining that the terminal device is a signal sent by a false ue according to the frequency of the received wireless signal and the corresponding first AMC address, the aforementioned preset frequency may be set as the probe frame frequency of the real terminal corresponding to the preset MAC address field, that is, the probe frame frequency of the ue produced by a specific device manufacturer.
It should be noted that, in this embodiment, the position of the planned virtual location point to be passed through should have a relationship with the position of the planned virtual location point at the latest moment, so as to avoid the problem that the corresponding wireless signal is identified as a signal sent by a false terminal due to the fluctuating change of the transmission power.
Further, planning a virtual location point may require consideration of environmental conditions in addition to the moving speed and the preset frequency. Taking the method provided by the embodiment as an example, if a pond is arranged in the park, the real user terminal cannot pass through the pond, and therefore it is necessary to avoid the virtual location point from being arranged in the area corresponding to the pond.
It should also be noted that, in practical applications, the path formed by the collecting device according to the collected wireless signals may systematically deviate from the path formed by the real user terminal when it passes through the real environment; for example: in the park scene, the path determined by the collecting device according to the wireless signal sent by the real user terminal does not pass through the pond, and the path determined according to the wireless signal sent by the false user terminal passes through the pond. In order to avoid that the collecting device determines false information by using systematic deviations, systematic errors can also be corrected by pre-testing, i.e. the position of the virtual location point is corrected.
It should be noted that in the implementation of the present application, the number of the wireless transmitters of the wireless router may be one, or may be multiple. In the case that the number of the wireless transmitters is one, the determination of the transmission power corresponding to the virtual position point is directly based on the distance between the virtual position point and the wireless transmitter. In the case where the number of wireless transmitters is plural, the transmission power may be determined according to the distance from the virtual location point to the nearest wireless transmitter.
In addition to providing the aforementioned method of hindering the collection of useful information, the present application also provides an apparatus for hindering the collection of useful information.
