Continuing to refer to fig. 2, a flow 200 of one embodiment of an information processing method for a first user device in accordance with the present application is shown. The information processing method comprises the following steps:
In this embodiment, an executing entity (e.g., the user equipment shown in fig. 1) of the information processing method for the first user equipment may broadcast the location information acquisition request to the second user equipment through a wired connection manner or a wireless connection manner in response to determining that the first user equipment fails to be located. The second user equipment is the second user equipment which is less than the preset distance away from the first user equipment. The position information acquisition request is a request for acquiring information indicating a position. The location information here may indicate where the first user equipment is located.
When the first user equipment cannot access the network and/or when the main power supply cannot supply power (for example, the main battery is unplugged), etc., a positioning failure of the mobile equipment may be caused.
In some application scenarios, the execution subject may broadcast the location information acquisition request by way of short-range mobile communication. In these application scenarios, the preset distance may be determined based on the reachable range of the short-range mobile communication. Here, the manner of short-range mobile communication may be, for example, transmission of radio waves. In addition, the distance smaller than the preset distance can be acquired in advance to be broadcasted to the second user equipment with the distance smaller than the preset distance through the network. For example, the addresses of the second user equipments less than the preset distance may be acquired in advance, and then broadcast to the second user equipments.
In this embodiment, the execution body may receive location data returned by the one or more second user equipments. The location data here includes location information determined by the second user equipment based on a location information acquisition request for performing the main body broadcast. The execution body also specifies time information corresponding to the specified position information. Specifically, the second user equipment determines its own location information at a certain time, and records time information indicating the time to obtain location information and time information in the updated data chain.
The number of second user equipments which return the position data here is one or two or more of the second user equipments which received the content broadcasted by the execution subject.
In this embodiment, the execution subject may determine the location data chain of the first user equipment based on the location data. Specifically, the execution body determines the location data chain of the first user equipment in various ways. The position data chain comprises a plurality of historical position data which are sequenced according to time sequence, and each historical position data comprises historical time and position information of the first user equipment at the historical time. For example, because the distance between the first user equipment and the second user equipment is small, the execution main body may directly use the location data returned by the second user equipment as the current location data of the first user equipment, and then add the current location data to the historical location data to obtain the location data chain. In addition, the location data may also be subjected to data processing, for example, where the location information is latitude and longitude data, and the location information is multiplied by a fixed coefficient or input into a specific formula to obtain current location data indicating the first user equipment. And adding the current position data to the historical position data to obtain a position data chain. The data chain comprises a plurality of data which are sequenced according to time sequence, and each data comprises historical time and position information of the first user equipment at the historical time.
Here, the location data returned by selecting the second user equipment may adopt location data returned by selecting the second user equipment closest to the first user equipment, may also adopt location data returned first, or may adopt random selection, and the like.
According to the method and the device, under the condition that the first user equipment fails to be positioned, the position data chain of the first user equipment is determined by using the second user equipment nearby. And the function of tracing the position of the first user equipment is realized through the position data chain.
With further reference to fig. 3, a flow 300 of yet another embodiment of an information processing method for a first user device is shown. The process 300 of the information processing method for the first user equipment includes the following steps:
In this embodiment, an execution subject (for example, the user equipment shown in fig. 1) on which the information processing method operates may encrypt the initial location information acquisition request with a preset encryption algorithm to generate the location information acquisition request. Here, the initial position information acquisition request is a position information acquisition request to be encrypted. The preset encryption algorithm is used for encrypting the initial position information acquisition request to obtain the position information acquisition request with the password being the preset password.
In this embodiment, an executing entity (e.g., the user equipment shown in fig. 1) of the information processing method for the first user equipment may broadcast the location information acquisition request to the second user equipment through a wired connection manner or a wireless connection manner in response to determining that the first user equipment fails to be located. The second user equipment is the second user equipment which is less than the preset distance away from the first user equipment. The position information acquisition request is a request for acquiring information indicating a position. The location information here may indicate where the first user equipment is located.
In this embodiment, the execution body may receive location data returned by the one or more second user equipments. The location data here includes location information determined by the second user equipment based on a location information acquisition request for performing the main body broadcast. The execution body also specifies time information corresponding to the specified position information. Specifically, the second user equipment determines its own location information at a certain time, and records time information indicating the time to obtain location information and time information in the updated data chain.
At step 304, a cyclic redundancy check is performed on the returned position data.
In this embodiment, the execution subject performs a Cyclic Redundancy Check (CRC) on the returned position data. The integrity and accuracy of the location data can be verified by a cyclic redundancy check.
And 305, if the returned position data passes the cyclic redundancy check, decrypting the position data according to a preset password.
In this embodiment, if it is determined that the returned location data passes the cyclic redundancy check, the execution main body decrypts the location data according to a preset password, so as to operate the location data.
In this embodiment, the execution subject may broadcast the networking capability acquisition request to at least one second user equipment. The device information acquisition request is a request for acquiring device information. The device information includes location capability information indicating whether the user device has location capability and/or networking capability information of an ability to interact with a cloud server.
In practice, the executing entity may execute the operation step of step 306 when determining that the executing entity does not have networking capability, that is, when the executing entity cannot send information to the cloud server. In particular, networking capability herein may refer to whether a device (such as the first user device described above) has the capability to interact with a cloud server. For example, if the user disconnects the first user equipment from the network, the first user equipment does not have networking capability.
And 307, receiving device information of the second user equipment returned by the second user equipment, wherein the device information comprises positioning capability information used for indicating whether the user equipment has positioning capability and/or networking capability information of capability of interacting with the cloud server.
In this embodiment, the execution main body receives the networking capability device information of the second user device returned by the second user device. That is, the information received by the execution main body may include not only the updated data link location data but also networking capability device information. The device information may also include device addresses or the like associated with the device.
The second user equipment can perform heartbeat data interaction with the cloud server to determine networking capability information. After receiving the location information acquisition request, the second user equipment may send networking capability information to the first user equipment to indicate that the first user equipment has or does not have the capability of interacting with the server.
The location capability information is information indicating whether the user equipment is capable of location. In particular, the user equipment may be located by GPS, beidou, etc.
In this embodiment, the execution main body selects a second user device closest to the first user device from at least one second user device, and takes the selected second user device as a target second user device.
In practice, the executing entity may determine the target second user equipment in a variety of ways. For example, the executing entity may directly determine the second user equipment with the strongest radio wave signal as the second user equipment with the closest distance, and further obtain the target second user equipment. The executing body may also select a second user equipment closest to the first user equipment from among second user equipments with networking capability as a target second user equipment, and specifically, the executing body may determine the second user equipment with the strongest radio wave signal as the second user equipment closest to the first user equipment, and determine whether the second user equipment has networking capability based on networking capability information returned by the second user equipment closest to the first user equipment. The radio wave may be, for example, a radio wave carrying updated data link and networking capability information. If it is determined to have networking capability, it may be determined that the second user device is a targeted second user device. If it is determined that the target second user equipment is not networking capable, the second user equipment with the second highest radio wave signal can be determined from at least two second user equipment. It may then be determined whether the second user device has networking capability based on the networking capability information of the second user device that is the second strongest signal. And if the second user equipment with the second highest signal strength is determined to have the networking capability, taking the second user equipment as the target second user equipment, and so on. In addition, the execution subject may further determine, from the second user devices returning the updated data chain, second user devices with networking capability from the second user devices according to the networking capability information returned by the second user devices. And selecting the second user equipment closest to the execution subject from the second user equipment with networking capability as the target second user equipment.
Furthermore, the executing body may determine the second user equipment with the strongest signal of radio waves as the second user equipment closest to the first user equipment, and determine whether the second user equipment has the positioning capability based on the positioning capability information returned by the second user equipment closest to the first user equipment. The radio waves herein may be, for example, radio waves carrying updated data link and location capability information. If it is determined to have location capability, the second user equipment may be determined to be the targeted second user equipment. If it is determined that there is no location capability, it may be determined that the second user equipment with the second strongest radio wave signal is the target second user equipment from among the at least two second user equipments.
In this embodiment, the execution subject may directly write the location data returned by the target second user equipment into its own location data chain, so as to update its own location data chain.
In this embodiment, the execution main body encrypts the updated location data chain of the first user equipment, and determines the encrypted location data chain as the location data chain of the first user equipment. Thus, the location data chain is more secure.
In this embodiment, the execution main body sends an information forwarding request to the target second user equipment, so that the target second user equipment sends the location data link of the first user equipment to the cloud server. In this way, the cloud server can determine the moving path of the first user equipment based on the location data chain of the first user equipment.
In some optional implementations, the information forwarding request may include a location data chain of the first user equipment, so that the target second user equipment may send to the cloud server.
According to the embodiment, the accuracy and the integrity of the position data chain can be improved through the cyclic redundancy check and the encryption and decryption functions. Meanwhile, the position of the first user equipment can be more accurately judged through the moving path. In addition, in the embodiment, by selecting the second user equipment closest to the first user equipment as the target second user equipment, the position data link can be sent to the cloud server through the target second user equipment under the condition that the first user equipment cannot access the network, and functions such as theft prevention can be better realized.
