Detailed Description
In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to overcome the defects that the data storage security cannot be effectively guaranteed and the process is relatively tedious when the write protection of the storage device is performed in the related art, a first embodiment of the present application provides a storage partition write protection method, for example, fig. 1 is a basic flowchart of the storage partition write protection method provided in this embodiment, where the storage partition write protection method includes the following steps:
step 101, when receiving data to be written, determining a target writing partition of the data to be written on a memory.
In particular, in practical applications, the memory may be different types of memories such as ROM, RAM, EPROM or EEPROM. In this embodiment, a memory is partitioned according to a preset partition rule in advance, and in the process of writing data, a partition sequenced before in all writable partitions may be determined as a target writing partition, or a writable partition may be randomly selected as a target writing partition, or a data attribute of data to be written and a partition attribute of the writable partition are acquired, and then a partition with a matching attribute is taken as a target writing partition. In addition, it should be noted that, in this embodiment, the number of the target writing partitions needed for the data to be written may be one or more, and is not limited herein.
And 102, writing the data to be written into the target writing partition.
Specifically, the writable area in the target write partition in this embodiment is in a write protection off state before the data to be written is written, that is, the writable area on the memory is defaulted to not start write protection in advance. It should be understood that the writable area in this embodiment is the smallest write unit of the target write partition, and may be, for example, a sub-partition further divided from the target write partition.
As shown in fig. 2, which is a schematic flow chart of a data writing method provided in this embodiment, in an optional implementation manner of this embodiment, when writing data to be written into a target writing partition, the method specifically includes the following steps:
step 1021, obtaining partition attribute information of the target writing partition;
step 1022, judging whether the partition attribute information meets the data writing condition of the data to be written;
and step 1023, writing the data to be written into the target writing partition when the data writing condition is met.
Specifically, in practical applications, the storage performance of all partitions in a storage unit is not reliable, so that the reliability evaluation of the partitions has a large influence on the data storage security.
Further, in an optional implementation manner of this embodiment, the partition attribute information includes: accumulating the number of times of erasing within a preset historical time period; judging whether the partition attribute information meets the data writing condition of the data to be written comprises the following steps: judging whether the accumulated erasing times are lower than a preset erasing time threshold value or not; and when the number of times of erasing is lower than the threshold value of the times of erasing, the data writing condition of the data to be written is met.
Specifically, in this embodiment, the data storage reliability of the partition may be evaluated based on the historical accumulated erasing times of the partition, and since the erasing times of the partition may reflect the aging degree of the partition to a greater extent, the determination of writing based on the accumulated erasing times of the partition has higher accuracy. The accumulated number of times of erasing may be a total number of times of erasing from the time of active use of the memory to the present time, or may be a total number of times of erasing within a certain period of time before, and is not limited herein.
In addition, in practical applications, the partition attribute information may also be determined as other factors, such as an average temperature or an average writing speed when data writing is performed within a preset historical time period, wherein if the average temperature is lower than a temperature standard value or the average writing speed is higher than a speed standard value, the target writing partition satisfies a data writing condition, and data writing is allowed.
And 103, when the data to be written is written completely, performing write protection starting processing on the target writing partition.
Specifically, write protection can protect the original data in the memory to prevent misoperation on one hand, and can avoid the attack of viruses on the data on the other hand. In this embodiment, the writable area in the memory partition is in a write-protection off state in advance, and the write-protection on processing of the partition is executed after data is written into the partition, on one hand, the write-protection on the written data can be realized only by performing the write-protection on processing, and the write-protection process is simplified; on the other hand, the area of the memory partition in which data can be written is not subjected to write protection in advance, so that write protection closing is not involved before data writing, and therefore, the risk that the written data is attacked due to write protection closing does not exist, that is, the writing of new data does not affect the write protection of the existing data in the memory, and the data storage security is effectively improved.
It should be noted that, in practical applications, if a single write of data to be written relates to multiple target write partitions, when performing write protection opening processing, the write protection opening processing may be performed after the write of the single partition is completed, or the write protection opening processing may be performed on all partitions in a unified manner after all partitions are completely written.
In an optional implementation manner of this embodiment, the performing write-protection opening processing on the target write partition includes: determining a write protection opening processing strategy corresponding to a target write partition; and performing write protection opening processing on the target write-in partition according to the write protection opening processing strategy.
Specifically, in this embodiment, the write protection opening processing policy is not unique, and in practical application, according to different practical application scenarios, a plurality of different write protection opening processing policies may be pre-formulated to meet different write protection requirements and data storage requirements.
In a typical embodiment, the write-protect open handling policy may include the following two: firstly, controlling a target write-in partition to integrally start a write-protection state; and secondly, controlling the target to be written into the partition, and starting a write protection state in an area in which data to be written is written.
In practical application, in order to ensure the efficiency of write protection and save processing performance, all partitions into which data to be written are written may be write protected, regardless of whether the partitions are full. And, in another case, in order to ensure the utilization rate of the storage space, when a single partition is not fully written, only the area in which data is written in the partition may be write-protected, and the unwritten area in the partition still maintains the write-protection closed state, for example, there are 10 sub-partitions in the current partition, and 6 of the sub-partitions are used for this data writing, so as to ensure that the storage space is not wasted, and the write-protection open state of the written sub-partitions is not affected when the remaining sub-partitions are written in the following, that is, to improve the utilization rate of the storage space and the data storage security at the same time, only the 6 sub-partitions that have been used may be opened, and the remaining 4 sub-partitions continue to maintain the original write-protection closed state.
In addition, it should be further noted that, in other embodiments of this embodiment, when the write protection enabling processing policy is to control the target write partition to enable the write protection state as a whole, if the target write partition is not full and a write requirement is still met for the non-full area in a subsequent data write process, so as to ensure a space utilization rate of the memory, when data write needs to be performed on a non-data written area of the partition in the subsequent process, the partition is controlled to perform write protection closing, so that data write is facilitated to continue, and then the write protection enabling processing is performed again after data write is completed.
In an optional implementation manner of this embodiment, determining the write protection opening processing policy corresponding to the target write partition includes: acquiring data writing attribute information for writing data to be written; and determining a write protection opening processing strategy corresponding to the target write partition based on the data write attribute information.
Specifically, the write-protection-on processing policy of this embodiment is determined based on the data write attribute information, and in practical application, the data write attribute is associated with a write action of performing data write on the data to be written this time, for example, a space usage amount of the data to be written on the target write partition, a data importance of the data to be written, a read-write frequency of the target write partition within a history time period, and the like, which is not uniquely defined in this embodiment.
For example, taking the data write attribute information as the space usage amount of the to-be-written data to the target write partition as an example, when determining the write protection opening processing policy corresponding to the target write partition based on the data write attribute information, determining whether the space usage amount of the to-be-written data to the target write partition is higher than a preset usage amount threshold, if so, determining that the write protection opening processing policy is to control the whole opening write protection state of the target write partition, and if not, determining that the write protection opening processing policy is to control the whole opening write protection state of the target write partition, and the area in which the to-be-written data is written is to open the write protection state.
In an optional implementation manner of this embodiment, after performing write protection opening processing on the target write partition, the method further includes: determining a write protection maintenance mechanism corresponding to the target write partition; and maintaining the write protection state opened by the target write partition based on a write protection maintaining mechanism.
Specifically, in practical application, the memory may be powered on/reset, so that in order to better meet specific use requirements, different write protection maintenance mechanisms are formulated based on different practical application scenarios to react differently to different operating states of the memory. It should be noted that the write protection maintenance mechanism of the present embodiment may include, but is not limited to, the following three: permanent maintenance, power-on maintenance, temporary maintenance.
The permanent maintenance, that is, the write protection state is always valid and cannot be revoked after being opened, and the opening of the write protection state can be still ensured after the memory is reset. For power-on maintenance, namely after the write protection state is started, the state is maintained before the memory is reset, and after the memory is reset, the write protection state is started to fail. In addition, for temporary maintenance, after the write protection state is started, the start of the write protection state is maintained only in the set maintaining time period, and the temporary maintenance is not influenced by the memory reset.
Based on the technical scheme of the embodiment of the application, when the data to be written is received, determining a target writing partition of the data to be written on the memory; writing data to be written into a target writing partition, wherein a writable area in the target writing partition is in a write protection closed state before the data to be written is written; and when the data to be written is written, performing write protection starting processing on the target write partition. Through the implementation of the scheme, the writable area in the memory partition is in the write protection closed state in advance, and the write protection opening processing of the partition is executed after the data are written into the partition, so that the data storage safety is effectively improved, and the write protection process is simplified.
The method in fig. 3 is a refined storage partition write protection method provided in a second embodiment of the present application, where the storage partition write protection method includes:
step 301, when receiving data to be written, determining a target writing partition of the data to be written on the memory.
Specifically, the memory in this embodiment may be different types of memories such as a ROM, a RAM, an EPROM, or an EEPROM, and one or more target writing partitions corresponding to the data to be written may be needed, which is not limited herein.
Step 302, obtaining the accumulated erasing times of the target writing partition in a preset historical time period, and judging whether the accumulated erasing times is lower than a preset erasing times threshold value.
And step 303, writing the data to be written into the target writing partition when the number of times of erasing is lower than the threshold value.
Specifically, the writable area in the target write partition in this embodiment is in a write-protection off state before the data to be written is written. In this embodiment, the data storage reliability of the partition is evaluated based on the historical accumulated erasing times of the partition, where a lower erasing time indicates that the current partition is aged to a lower degree and is more reliable.
And step 304, when the data to be written is written, acquiring data writing attribute information for writing the data to be written.
Specifically, the data writing attribute in this embodiment is associated with a writing behavior of data writing to the data to be written this time, for example, a space usage amount of the data to be written to the target writing partition, a data importance of the data to be written, a reading and writing frequency of the target writing partition in a historical time period, and the like.
Step 305, determining a write protection opening processing strategy corresponding to the target write partition based on the data write attribute information.
The write-protection opening processing strategy of the embodiment may include the following two types: firstly, controlling a target write-in partition to integrally start a write-protection state; and secondly, controlling the target to be written into the partition, and starting a write protection state in an area in which data to be written is written.
And step 306, performing write protection opening processing on the target write-in partition according to the write protection opening processing strategy.
According to different practical application scenarios, a plurality of different write protection opening processing strategies can be preset so as to meet different write protection requirements and data storage requirements.
Step 307, determining a write protection maintenance mechanism corresponding to the target write partition, and maintaining the write protection state opened by the target write partition based on the write protection maintenance mechanism.
The write protection maintenance mechanism of the present embodiment may include, but is not limited to, the following three: permanent maintenance, power-on maintenance, temporary maintenance. The embodiment makes different write protection maintenance mechanisms based on different practical application scenes so as to make different reactions to different working states of the memory.
It should be understood that, the size of the serial number of each step in this embodiment does not mean the execution sequence of the step, and the execution sequence of each step should be determined by its function and inherent logic, and should not be limited uniquely to the implementation process of the embodiment of the present application.

Through the implementation of the scheme, the writable area in the memory partition is in the write protection closed state in advance, and the write protection opening processing of the partition is executed after the data are written into the partition, so that the data storage safety is effectively improved, and the write protection process is simplified.
