The Memory 1005 may be a Random Access Memory (RAM) Memory, or may be a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the Beidou positioning based hard disk protection device, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, the memory 1005, which is a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and a hard disk protection program based on the beidou positioning.
In the hard disk protection device based on the beidou positioning shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 of the hard disk protection device based on Beidou positioning can be arranged in the hard disk protection device based on Beidou positioning, and the hard disk protection device based on Beidou positioning calls the hard disk protection program based on Beidou positioning stored in the memory 1005 through the processor 1001 and executes the hard disk protection method based on Beidou positioning provided by the embodiment of the invention.
The embodiment of the invention provides a hard disk protection method based on Beidou positioning, and referring to FIG. 2, FIG. 2 is a schematic flow diagram of a first embodiment of the hard disk protection method based on Beidou positioning.
In this embodiment, the hard disk protection method based on Beidou positioning includes the following steps:
step S10: acquiring Beidou positioning information of a hard disk in real time, and determining the position coordinate of the hard disk according to the Beidou positioning information;
it should be noted that the execution main body of the embodiment is a hard disk protection device based on the Beidou positioning, the device may be a smart phone, a smart watch, a portable computer or other devices with the same or similar functions, and the embodiment takes the hard disk protection device based on the Beidou positioning as an example for description, and does not constitute a limitation to the embodiment.
It should be understood that the Beidou satellite navigation system consists of a space section, a ground section and a user section, can provide high-precision, high-reliability positioning, navigation and time service for various users all day long in the world, has short message communication capacity, and initially has regional navigation, positioning and time service capacities, wherein the positioning precision is decimeter and centimeter level, the speed measurement precision is 0.2 meter/second, and the time service precision is 10 nanoseconds.
Understandably, the Beidou chip is preassembled in the hard disk and can receive signals transmitted by a Beidou satellite so as to complete positioning, and communication connection is established between the hard disk and hard disk protection equipment based on Beidou positioning so that Beidou positioning information of the hard disk can be acquired in real time.
It should be understood that Beidou positioning can provide positioning with centimeter-level accuracy, and accurate position coordinates of the hard disk in the space can be determined through Beidou positioning information.
Step S20: when the position coordinate is out of a preset range, sending a read-write forbidding instruction to the hard disk so that the hard disk forbids a read-write function according to the read-write forbidding instruction;
it can be understood that the preset range is a safe space range where the hard disk is located, and can be set according to specific use conditions, for example, the hard disk is used in an office within a period of time, and at this time, the preset range can be set as the space range of the office, and if the use place of the hard disk is changed, the preset range can be set as the space range of a new use place.
It should be understood that when the position coordinate of the hard disk is determined to be within the preset range through the Beidou positioning information of the hard disk, the hard disk is used within the safety range, at the moment, the hard disk can be normally used, when the position coordinate of the hard disk is outside the preset range, the hard disk is used outside the safety range, and at the moment, the risk of leakage of hard disk data exists.
It can be understood that when the position coordinates of the hard disk are used for determining that the hard disk is out of the preset range, the hard disk may be taken away from the preset range by a hard disk user, at the moment, a read-write forbidding instruction is sent to the hard disk, and after the hard disk receives the instruction, the read-write function of the hard disk is forbidden.
It should be understood that, in order to remind the user to find the position of the hard disk in time, when the position coordinates of the hard disk are determined to be out of the preset range, prompt information is sent to the hard disk protection device to remind the user to respond according to actual conditions in time.
Step S30: acquiring the duration of the hard disk outside a preset range;
it should be understood that, when it is determined that the hard disk is outside the preset range according to the position coordinates of the hard disk, timing may be started to obtain the duration of time that the hard disk is outside the preset range.
Step S40: and when the duration is longer than the preset duration, sending a data destruction instruction to the hard disk so that the hard disk destroys the stored data according to the data destruction instruction.
It can be understood that the preset time is the safe time when the hard disk is outside the preset range, and when the time when the hard disk is outside the preset range is longer than the preset time, it indicates that the risk of hard disk data leakage has reached the highest level, and at this time, the hard disk data needs to be destroyed.
It should be understood that the data destruction instruction is an instruction for controlling the hard disk to destroy the stored data, which is sent by the hard disk protection device based on the beidou, and after receiving the instruction, the hard disk starts the operation of destroying the data.
Further, in order to improve the security of the hard disk data, the step S40 includes:
when the duration is longer than the preset duration, acquiring the security priority of the data stored in the hard disk; and sending a data destruction instruction to the hard disk so that the hard disk destroys the stored data according to the data destruction instruction and the security priority.
It will be appreciated that security priority is the priority set by the hard disk owner in terms of the importance of storing data.
It should be understood that when the duration of the hard disk outside the preset range is longer than the preset duration, the hard disk data needs to be destroyed, at this time, the security priority of the hard disk data stored is first obtained, and the importance degree of the hard disk data stored can be obtained according to the security priority.
It can be understood that a certain time is required for destroying data, in the process of destroying data, a situation that protective measures of a hard disk are cracked exists, if important stored data are not completely destroyed at the moment, great loss can be caused, when the hard disk is used for storing data, a safety priority can be set according to the importance degree of the data, when the data are destroyed, the importance degree of the data can be determined according to the safety priority, the data with high safety priority are destroyed first, and therefore leakage of the important data is avoided to the greatest extent.
Further, in order to ensure that the data stored in the hard disk cannot be restored after being destroyed and improve the security of the data, the sending of the data destruction instruction to the hard disk so that the hard disk destroys the stored data according to the data destruction instruction and the security priority includes:
sending a data destruction instruction to the hard disk so that the hard disk overwrites the stored data according to the data destruction instruction and the security priority; when the overwriting of the stored data is completed, the built-in resistance coil of the hard disk is controlled to be electrified to generate a strong magnetic field to destroy the overwritten stored data.
It will be appreciated that overwriting is the process of writing non-secure data to the hard disk cluster that stores the secure data. The data on the hard disk are stored in binary "1" and "0" forms. The original stored secret data on the hard disk is repeatedly covered by meaningless and irregular information, so that the original data can not be known to be 1 or 0, and the purpose of destroying the hard disk data is achieved. The data can be divided into bit-by-bit overwriting, skip bit overwriting, random overwriting and other modes according to the specific sequence when the data is overwritten. A
It should be understood that the magnetic grains on the disk surface of the hard disk are arranged along the track direction, and different N/S pole connection directions represent data 0 and 1, respectively, so as to achieve the effect of recording data.
It can be understood that the resistance coil and the power supply for supplying power to the resistance coil are arranged in the hard disk, after the data stored in the hard disk is destroyed by overwriting, the resistance coil arranged in the hard disk is electrified, a strong magnetic field can be generated instantly, after the hard disk is influenced by the strong magnetic field, the magnetic particles can be uniformly arranged along the field intensity direction to become 0 or 1 with a clear color, the data recorded in the hard disk can be erased, and the hard disk can lose the data recording function.
Further, after step S20, to implement backup of lost hard disk data, the method further includes: sending a data transmission instruction and a preset generating polynomial to the hard disk so that the hard disk generates backup data according to the preset generating polynomial and a hard disk storage data sequence, and sending the backup data to a cloud end; and when the cloud end receives the backup data, the preset generating polynomial is sent to the cloud end, so that the cloud end carries out cyclic redundancy check on the backup data according to the preset generating polynomial, and when the check is passed, the backup data is marked as safe storage data.
It should be understood that, in order to back up important data in a lost hard disk, a communication module may be built in the hard disk for transmitting data, a data transmission error may occur during data transmission, and in order to ensure accuracy of data transmission, a cyclic redundancy check algorithm may be used to check the transmitted data.
It is understood that the predetermined generator polynomial is a polynomial that generates a cyclic redundancy check code when performing a cyclic redundancy check algorithm.
It can be understood that when the cyclic redundancy check algorithm is used for checking the transmitted storage data, the preset generating polynomial is sent to the hard disk, when the hard disk transmits the storage data, the cyclic redundancy check code is generated according to the preset generating polynomial, and then the backup data is generated according to the storage data and the cyclic redundancy check code and transmitted to the cloud.
It should be understood that after the cloud receives the backup data, the accuracy of the received backup data needs to be checked, at this time, the hard disk protection device based on the Beidou positioning sends the preset generating polynomial to the cloud, the preset generating polynomial is used for dividing the polynomial of the backup data, if the polynomial can be divided completely, the transmitted data is correct, the check is passed, and at this time, the backup data is marked as safe data.
In a particular implementation, for example: presetting a generator polynomial as G (x) = x 4 + x +1, whose binary expression is 10011, 5 bits in total, where k =4, assuming that the binary of the storage data sequence to be transmitted by the hard disk is 101011, adding 40 s after the storage data to be transmitted, and the binary expression is 1010110000, 10 bits in total, at this time, removing 1010110000 from the binary expression 10011 of the preset generating polynomial, obtaining 0100 as the redundant cyclic check code according to the modulo-2 algorithm, adding the cyclic redundancy check code to the back of the data to be transmitted, and obtaining the bit stream of the backup data transmitted to the cloud: 1010110100, wherein the first 6 bits are original data and the last 4 bits are cyclic redundancy check codeAfter receiving the backup data with the cyclic redundancy check code, dividing the backup data by the generating polynomial, if the data has no error in the transmission process, the data can be definitely divided by the same generating polynomial G (x), and if the data has an error in the transmission process, the result obtained after the generating polynomial G (x) is removed is certainly not 0.
In the embodiment, the position coordinates of the hard disk are determined according to the Beidou positioning information by acquiring the Beidou positioning information of the hard disk in real time; when the position coordinate is out of the preset range, sending a read-write forbidding instruction to the hard disk so that the hard disk forbids a read-write function according to the read-write forbidding instruction; acquiring the duration of the hard disk outside a preset range; when the duration is longer than the preset duration, a data destruction instruction is sent to the hard disk so that the hard disk destroys the stored data according to the data destruction instruction.
Referring to fig. 3, fig. 3 is a schematic flow chart of a hard disk protection method based on Beidou positioning according to a second embodiment of the present invention.
Based on the first embodiment, in this embodiment, after the step S10, the method further includes:
step S101: monitoring shell state information of the hard disk through a preset sensor, and judging whether the shell of the hard disk is illegally opened according to the shell state information;
it should be understood that the preset sensor includes a light sensor and a distance sensor, and the change of the hard disk housing can be judged according to the data monitored by the sensor.
It will be understood that illegal opening includes breaking the housing with brute force, opening the housing without opening authority, or otherwise opening the housing.
It can be understood that when the hard disk shell is damaged, the light detected by the light sensor and the distance detected by the distance sensor are changed, so that whether the shell is illegally opened can be judged.
Step S102: and when the shell of the hard disk is illegally opened, sending a data destruction instruction to the hard disk so that the hard disk destroys the stored data according to the data destruction instruction.
Understandably, when the shell is illegally opened, in order to avoid data leakage, the hard disk protection device based on Beidou positioning sends a data destruction instruction, so that the hard disk destroys the stored data according to the instruction.
Further, in order to improve the accuracy of determining whether the hard disk shell is illegally opened, the method of monitoring the shell state information of the hard disk through the preset sensor and determining whether the hard disk shell is illegally opened according to the shell state information includes:
monitoring the distance change between the shell of the hard disk and the internal elements of the hard disk and the light intensity inside the hard disk shell by a preset sensor; and when the distance change is greater than a preset distance threshold value or the light intensity is greater than a preset intensity, judging that the shell of the hard disk is illegally opened.
It will be appreciated that in determining the change in distance, an internal element of the hard disk may be selected as a reference, and that in normal use of the hard disk, the distance between the sensor and the internal element of the reference is unchanged or changes very little.
It can be understood that when the hard disk is normally used, the light intensity inside the hard disk shell is basically unchanged, so that the sensor can be used for monitoring the light intensity inside the shell to judge whether the shell is illegally opened.
It can be understood that the preset distance threshold is a value of the maximum distance change generated by the shell relative to the internal element of the reference when the shell is deformed normally, and the preset intensity is the maximum illumination intensity which can be monitored in the shell when the hard disk is in normal use.
In the embodiment, the shell state information of the hard disk is monitored through a preset sensor, and whether the shell of the hard disk is illegally opened or not is judged according to the shell state information; when the shell of the hard disk is illegally opened, a data destruction instruction is sent to the hard disk so that the hard disk destroys the stored data according to the data destruction instruction.
Referring to fig. 4, fig. 4 is a schematic flowchart of a hard disk protection method based on Beidou positioning according to a third embodiment of the present invention.
Based on the foregoing embodiments, in this embodiment, after the step S20, the method further includes:
step S201: acquiring a fingerprint verification result of the hard disk when the position coordinate of the hard disk is changed from being out of a preset range to being within the preset range within a preset time;
understandably, after fingerprint verification is carried out on the hard disk by the built-in fingerprint identification module of the hard disk, the hard disk can send a fingerprint verification result to the hard disk protection equipment based on Beidou positioning.
It should be understood that when the hard disk is outside the preset range, the hard disk is controlled to disable the read-write function, if the position coordinates of the hard disk are determined to be within the preset time, the hard disk returns to the preset range from outside the preset range, the risk of data leakage of the hard disk can be judged to be low, and the hard disk can be normally used after fingerprint verification.
Step S202: when the fingerprint verification result is that the fingerprint verification passes, sending a restoration instruction to the hard disk so that the hard disk is restored to a normal read-write state according to the restoration instruction;
it can be understood that the condition that the fingerprint verification passes can be that at least one fingerprint verification is successful within the preset times, at the moment, the forbidden read-write function is removed, and the hard disk is restored to the normal state.
Step S203: and when the fingerprint verification result is that the verification fails, sending a data destruction instruction to the hard disk so that the hard disk destroys the stored data according to the destruction instruction.
It can be understood that the condition of fingerprint verification failure can be that fingerprint verification fails completely within preset times, at this time, the stored data of the hard disk has a leakage risk, a data destruction instruction is sent to the hard disk, and the stored data of the hard disk is destroyed after the hard disk receives the instruction.
In the embodiment, when the position coordinate of the hard disk is changed from being out of the preset range to being within the preset range within the preset time, the fingerprint verification result of the hard disk is obtained; when the fingerprint verification result is that the fingerprint verification passes, sending a restoration instruction to the hard disk so that the hard disk is restored to a normal read-write state according to the restoration instruction; and when the fingerprint verification result is verification failure, sending a data destruction instruction to the hard disk so that the hard disk destroys stored data according to the destruction instruction.
In addition, the embodiment of the invention also provides a storage medium, wherein the storage medium stores a hard disk protection program based on Beidou positioning, and the hard disk protection program based on Beidou positioning realizes the steps of the hard disk protection method based on Beidou positioning when being executed by a processor.
