These devices are readily accessible under certain conditions, so that reading sensitive data held by the storage device results in the disclosure of critical important information content. Currently, most of existing data destruction technologies pay attention to whether data blocks in a data destruction technology means can read data and destroy data efficiency, but when data destruction is determined, a signal for starting or sending one-key destruction (such as equipment loss, equipment theft and incapability of executing destruction operation in military exercises) needs to be sent at any time, so that the data information stored in the equipment still has a great leakage risk. That is to say, most of the existing technical solutions at present explain that data or storage media can be destroyed quickly after receiving a destruction signal, but do not explain when triggering the destruction signal, for example, in military war, once the device is intercepted by an enemy, and when the destruction signal is not sent, data destruction cannot be completed, resulting in information leakage. How to intelligently and automatically identify the risk of disclosure of the storage device or the whole device and automatically start a data destruction program to eliminate information safety hidden dangers when the risk is identified is a difficult problem to be solved urgently.
The core of the technology of the scheme is that whether the data storage state is wholly dangerous or not is judged by sensing the data environment, so that whether the whole stored data is thoroughly destroyed or not is judged, and the whole data leakage caused by reproducing malicious storage media is avoided. The design of the scheme is mainly characterized in that the key point of protection is that the automatic or manual data destruction triggering technology can be combined with the existing data destruction algorithm when the factor environment changes, so that the technology of the existing mainstream design scheme for rapidly destroying and deleting data is overcome, the data deletion technology is triggered by the factors and the environment without knowing the time and the factors, and the data is deleted and destroyed to eliminate the potential safety hazard of information leakage.

Detailed Description
For a clearer understanding of the contents of the present invention, reference will be made to the accompanying drawings and examples.
Fig. 1 is a flowchart of a data automatic destruction method based on multi-factor environmental awareness according to the present invention, which includes a step a of setting a multi-factor check application based on multi-factor environmental awareness for a storage medium to be protected, where a factor list including multi-factor environmental awareness is preset in the multi-factor check application, and a data reading factor condition with a security protection mechanism is set according to an actual need according to the factor list; B. when a read-write request aiming at the data content of a storage medium needing to be protected occurs, automatically starting a multi-factor checking application program and detecting whether a preset factor list exists or not, automatically calling a data destruction instruction to automatically destroy data when the detection result is negative (namely the factor list does not exist), and entering the following steps when the detection result is positive (namely the factor list exists); C. checking the factor condition under the current read-write request environment according to the set data read factor condition; and when the multi-factor checking application program judges that the factor condition in the current read-write request environment meets the set data reading factor condition, allowing the data read-write request to be executed, otherwise, automatically calling a data destruction instruction to automatically destroy the data. According to the method, after factors needing to be checked for data reading and writing and corresponding data reading factor conditions are preset in advance, multi-factor comparison is carried out on data during each reading, and once the conditions are inconsistent with the preset data reading factor conditions, data destruction is triggered immediately. The method can also be combined with the existing data destruction scheme, and the existing data destruction scheme is called once the preset data reading factor conditions are found to be inconsistent.
Specifically, in the method for automatically destroying data based on multi-factor environmental awareness, step a sets a multi-factor check application program, wherein the program is preferably a read-only program written into a specific write-once data space in a storage medium, and the specific write-once data space is a data space in a read-only state after being written once (supported by most hardware storage media, only one data space is allowed to be written once, and the data space area is changed into the read-only state later), and the data space cannot be changed and deleted after being written, and the operation of the multi-factor check application program is triggered when a data read-write request is sent to the storage medium; the storage medium comprises the existing mechanical hard disk, solid state hard disk, removable storage medium, erasable optical disk and the like; the multi-factor checking application program is internally preset with a factor list containing multi-factor environmental sensing, and a data reading factor condition with a safety protection mechanism is set according to the actual requirement of the factor list, wherein the multi-factor is a plurality of environmental sensing factors, preferably comprises hardware equipment information (such as mainboard information, MAC address information, cpu information, memory information, peripheral information and the like) depended by a storage medium, BIOS information used by the storage medium, operating system information (such as operating system version information, specific application program value information, specific drive information and the like) used by the storage medium, and factor list information (such as list content integrity information, list content modification information and the like); the factor of the generated factor list can be a single condition or a combination of a plurality of conditions, and the combination condition can be defined by a user according to the requirement of the user, for example, the version of the operating system is selected as the factor list, and only the condition of judging the version of the operating system can be used as the condition of the data reading factor; two combinations of the version of the operating system and the time for reading the data can also be used as factor lists, and two combination conditions of the version of the operating system and the time for reading the data can be used as data reading factor conditions. Step B, when a read-write request aiming at the data content of the storage medium needing to be protected occurs, automatically starting the multi-factor check application program and detecting whether a preset factor list exists or not, automatically calling a data destruction instruction to automatically destroy the data if the detection result is negative, continuously executing a plurality of formatting operations on the storage medium after automatically deleting the data by adopting a data destruction algorithm when automatically destroying the data, for example, continuously formatting the storage medium for more than 10 times, preferably entering step B' to detect whether the preset factor list is tampered or not when the detection result is that the factor list exists, and executing step C when the preset factor list is detected to be tampered. Preferably, whether a preset factor list is tampered or not can be detected by adopting an encryption and decryption technology or a backup technology, for example, the factor list can be opened only after a secret key is obtained by adopting the encryption and decryption technology, the factor list is determined to be tampered when the factor list cannot be opened in a plaintext mode or the opened factor list is messy codes, and a data destruction instruction is automatically called to automatically destroy data; when the backup technology is adopted, more than two identical factor lists (three factor lists are generated simultaneously) are generated simultaneously by adopting a multi-copy mode when the factor lists are preset in the step A, whether all the factor lists are consistent is checked when whether the preset factor lists are tampered in the step B', and a data destruction instruction is automatically called to automatically destroy data when the factor lists are confirmed to be tampered when one list and the other two factor lists are inconsistent. And step C, checking the factor condition under the current read-write request environment according to the set data reading factor condition, allowing the data read-write request to be executed when the multi-factor checking application program judges that the factor condition under the current read-write request environment meets the set data reading factor condition, and otherwise, automatically calling a data destruction instruction to automatically destroy the data.
When judging whether to trigger data destruction when reading data, the data destruction can be triggered by the data in the storage medium according to a data reading factor condition or by a certain data according to a certain data reading factor condition, and the data destruction can be defined by a user according to the requirement of the user. If the user A defines the data stored in all the storage media, the data is automatically destroyed once the version of the operating system is changed during reading. For example, the set factor list contains the operating system version win7, which has access to IP address 192.168.1.230, MAC address 5E: 23: 3F: 39: 00, motherboard number 0000-. The automatic data destruction method of the invention puts the pre-prepared multi-factor environmental perception factor list into the storage medium together, and starts the list protection mechanism to prevent the list from being modified, when the application process writes in data each time, the multi-factor checking application program is automatically started, the written data is marked according to the data reading factor condition in the multi-factor list, and whether the data meets the data reading factor condition in the factor list is checked when the data is read or modified, once the data meets the data reading factor condition, the environment of the storage medium is changed, and the data destruction is immediately executed.
