In this embodiment, it should be noted that the industry data long storage method may be applied to an industry data long storage device, where the industry data long storage device belongs to an industry data long storage system, and the industry data long storage system belongs to an industry data long storage apparatus.
In this embodiment, a specific application scenario may be:
when a developer needs to store important data in the device, in the prior art, a database or an NVRAM is generally selected, wherein the database is erased after the device is restored to the factory setting, and only a PRODUCT_INFO area in the NVRAM can be reserved after the device is restored to the factory setting. But the area is used by the system, and stores important data such as Barcode, IMEI code, WIFI MAC address and the like, and only a reserved space of hundreds of bytes is available for a developer, so that the data storage amount is small. And the data block is not protected, so that a developer can randomly write and erase, and the security is low.
When multiple developers are in use, the currently used developers do not know which data blocks are already used, so that different data are easily overlaid, and the use is inconvenient.
The embodiment is applied to the NVRAM, wherein the NVRAM has the characteristics of high access speed of main memory and the characteristics of large auxiliary memory capacity and non-volatile (data is not lost after power failure), and the data stored in the memory space of the NVRAM can be reserved after factory setting is restored, so that the data is reserved after the factory setting is restored for the equipment, and the NVRAM is selected as the bearing memory.
The whole embodiment opens up a storage space, namely a backup data block, in the NVRAM, and sets access limit of a data processing request in the NVRAM, so as to provide a safe and reliable data processing mode which can still save data after switching on and switching off or restoring factory settings.
The method comprises the following specific steps:
step S100, receiving a data processing request of a user side;
in this embodiment, the terminal receives the data processing request sent by the user terminal through the corresponding communication interface, where the communication interface may adopt a current network communication mode, may adopt a UDP (User Datagram Protocol, user data packet protocol) mode, may also adopt a TCP (Transmission Control Protocol ) mode, and is not specifically limited herein.
In this embodiment, the request may be a process request; the data processing includes reading, writing and erasing, wherein at least one of the processing modes is adopted in the data processing, for example, the terminal receives a data reading request from the user terminal, which indicates that the user terminal is to read the data stored in the terminal.
Step S200, determining access limit of the data processing request, and judging whether the data processing request is safe or not based on the access limit;
in this embodiment, the access restriction may be used to restrict the access of the system application to the data, or may be used to restrict the access of other users to the data, where the access restriction is used to determine whether the data processing request is trusted, prevent the stored data from being tampered with maliciously, and ensure the security of the stored data by setting the access restriction.
Specifically, the step S200 includes the following steps S210 to S220:
step S210, detecting whether the data processing request is on a preset white list or not based on the data processing request of the user side;
in this embodiment, a data processing request white list is created, and a trusted data processing request is added in the white list, that is, a preset white list is completed, where the trusted data processing request may be a data processing request of a system administrator, or may be a target trusted data processing request set by a developer and/or an administrator.
Step S220, if the data processing request is on the preset white list, determining that the data processing request is safe.
In this embodiment, the non-trusted data processing request is refused through the preset white list to ensure the security of the data in the backup data block, for example, the application APP in the device sends a data access process to the terminal, the data processing request is the non-trusted data processing request, and if the terminal detects that the data processing request is not in the white list, the process is refused to access the data, thereby preventing malicious tampering of the stored data and protecting the security of the data in the backup data block.
Step S300, if the security is ensured, determining the type of the data processing request;
in this embodiment, the terminal determines the type of the data processing request by identifying the operation parameter carried by the data processing request, the type of the data processing request including a read type and an edit type, specifically, a read as read operation request, and the edit includes a write operation request and an erase operation request.
Step S400, based on the type, carrying out data processing on target data in the backup data block pointed by the data processing request to obtain processed data;
in this embodiment, the backup data block is a block of storage space opened up in the NVRAM, and is used for storing data, the target data is pointed to according to a data processing request, or alternatively, a piece of data stored in the backup data block is selected, the data processing is performed correspondingly based on the type of the data processing request, for example, if the data processing request is a read request, the target data is read.
It should be noted that, if any data is not yet stored in the backup data block, the target data is empty, and the processing of the target data can only be writing data or storing data.
Step S500, further processing the processed data based on the type to obtain a processing result;
wherein the backup data block is arranged in a nonvolatile random access memory.
In this embodiment, the backup data block is established in the identifier space of the nonvolatile random access memory through the encoding end, specifically, the encoding end initializes the nonvolatile random access memory to generate the identifier space, selects the spare identifier space therein, and rebuilds the backup data block in the spare identifier space, where the storage space of the backup data block is large and is suitable for storing a large amount of data; the data is arranged in the identification space of the nonvolatile random access memory, so that the integrity of the data after the equipment is restored to the factory setting is ensured.
In this embodiment, the nonvolatile random access memory may be PCM (Phase Change Memory ), STT-RAM (Spin-Transfer Torque Random Access Memory, spin transfer torque random access memory), RRAM (Resistive Random Access Memory, memristor), or 3D XPoint proposed by Intel (Intel) and light-beautifying (Micron), which is not limited herein.
Specifically, the step S500 includes the following steps S510 to S520:
step S510, when the data processing request is of a read type, sending the processed data to a user side to obtain a read result of the target data;
and step S520, when the data processing request is of an editing type, in the backup data block, performing second position allocation on the processed data, and then storing the processed data in the second position to obtain a storage result of the target data.
In this embodiment, the second location is a data location of the data after the editing operation allocated to the backup data block by the terminal, where the data location is managed and allocated by the terminal, and the backup data block service set by the terminal may also manage and allocate the data before and after editing, which is beneficial to convenience when multiple developers use the backup data block to process the data.
