The application discloses a data storage method, a data storage device, computer equipment and a storage medium, which specifically can comprise the following contents: according to the data read-write times of the candidate storage blocks and the use states of the candidate storage blocks, the target storage blocks are determined from the candidate storage blocks, and then target data to be written into the user identification card are written into the target storage blocks.
In one embodiment, as shown in fig. 2, fig. 2 is a flowchart of a data storage method provided in an embodiment of the present application, where a data storage method performed by a computer device in fig. 1 may include the following steps:
step 201, obtaining target data to be written into a subscriber identity module card.
It should be noted that, the target data refers to data to be written into the subscriber identity card, and the data types of the target data may include, but are not limited to: authentication key data, user identity data, terminal communication data, application data, file object data, and the like.
Further, when the target data to be written into the user identification card needs to be obtained, determining the data type of the candidate data, further judging whether the data of the candidate data belongs to the data type of the target data, and if so, taking the candidate data as the target data to be written into the user identification card; if the candidate data does not belong to the user identification card, determining that the candidate data is not the target data to be written into the user identification card.
Step 202, selecting a target storage block from the candidate storage blocks according to the data read-write times of the candidate storage blocks in the user identification card and the use state of the candidate storage blocks.
Wherein the target memory block refers to a candidate memory block for storing target data.
The use states of the candidate storage blocks include: an occupied state in the case where the data storage block has stored data and an idle state in the case where the data storage block has not stored data.
It should be noted that, in order to prevent the same memory block from performing data read-write operations repeatedly and continuously, thereby affecting the service life of the user identification card, the target memory block can be selected from the candidate memory blocks according to the data read-write times of the candidate memory blocks in the user identification card and the use state of the candidate memory blocks, so as to ensure the balance of the data read times of each candidate data block and achieve the purpose of prolonging the service life of the user identification card.
Further, the target storage block can be determined from the candidate storage blocks only according to the data read-write times of the candidate storage blocks; specifically, when the target storage block needs to be determined, the candidate storage block with the minimum data read-write times is selected as the target storage block according to the data read-write times of the candidate storage block, so that the phenomenon that a certain candidate storage block performs read-write operation for many times is prevented, and the service life of the user identification card is influenced.
And if the data read-write times of at least two candidate storage blocks are the same and are the minimum values, randomly selecting one candidate storage block from the at least two candidate storage blocks as a target storage block.
Further illustratively, the target memory block may be determined from the candidate memory blocks based solely on the use status of the candidate memory blocks; specifically, when the target memory block needs to be determined, a candidate memory block whose use state is an idle state is selected as the target memory block for storing the target data according to the use state of the candidate memory block. Therefore, the occurrence of a certain candidate storage block is prevented from simultaneously writing a plurality of data, and the service life of the user identification card is reduced.
And if the use state of at least two candidate storage blocks is the idle state, randomly selecting one candidate storage block from the at least two candidate storage blocks as a target storage block.
Further, to further ensure the service life of the subscriber identity module card, the target memory block for storing the target data may be determined from the candidate memory blocks according to the number of times of data reading and writing of the candidate memory block and the use state of the candidate memory block. Specifically, the candidate storage block with the idle use state and the least data reading and writing times is selected as the target storage block for storing the target data, so that the balance of the data reading times of each candidate data block is ensured, and the purpose of prolonging the service life of the user identification card is achieved.
In one embodiment of the present application, when the target storage block needs to be determined from the candidate storage blocks, a spare storage block whose usage state is an idle state may be selected from the candidate storage blocks according to the usage state of the candidate storage blocks, and the target storage block with the minimum data read-write number may be determined from the spare storage blocks according to the data read-write number of the candidate storage blocks.
Further, if the usage states of the candidate memory blocks are all occupied states, the occupied time length of each candidate memory block entering the occupied state is obtained, N candidate memory blocks with the longest occupied time length are used as standby memory blocks, and further, a target memory block with the minimum data read-write times is determined from the standby memory blocks according to the data read-write times of the candidate memory blocks. Wherein, N is a positive integer greater than or equal to 1, the value of N can be set and adjusted according to the historical experience and actual condition of staff, and the value range of N is not limited.
In an embodiment of the present application, when a target storage block needs to be selected from candidate storage blocks, a value of N may be preset to be 3, if the use states of the candidate storage blocks at the current moment are all occupied states, an occupied time of the candidate storage blocks is obtained, 3 candidate storage blocks with the longest occupied time are used as spare storage blocks, and further, according to the data read-write times of the candidate storage blocks, a target storage block with the minimum data read-write times is determined from the spare storage blocks.
Step 203, the target data is written into the target storage block.
It should be noted that, the information address book is stored in the user identification card, and the number of times of data reading and writing of the candidate storage block and the usage state of the candidate storage block are recorded in the information address book, so after the target data is written into the target storage block, the number of times of data reading and writing of the candidate storage block and the usage state of the candidate storage block in the information address book can be updated, so that the content recorded in the information address book accords with the actual situation of the candidate data block.
Further, the information address book may further record a data identifier written in the candidate storage block, so as to ensure that a user can determine a storage location of the data (i.e. the candidate storage block in which the positioning data is written) according to the content recorded in the information address book.
According to the data storage method, according to the data reading and writing times of the candidate storage blocks and the use state of the candidate storage blocks, the target storage blocks are determined from the candidate storage blocks, and then target data to be written into the user identification card are written into the target storage blocks. According to the above-mentioned in-process can know, this application can be according to the data read-write number of times of candidate storage block and the service condition of candidate storage block, select the target storage block from candidate storage block, compare in prior art, only according to the data type of target data, store this target data in the storage block of corresponding data type, this application has avoided when user identification card write into the target data of same type many times appear the condition that frequently read-write appears in same storage block, and then, avoid causing the life reduction of user identification card even the condition that user identification card damaged.
In one embodiment, the performance and the service life of the subscriber identity card are reduced as the number of data read/write operations is increased. To prevent the above problem, the service life and performance of the subscriber identity module card may be reduced, as shown in fig. 3, by selecting a target memory block from the candidate memory blocks according to the number of times of data reading and writing of the candidate memory blocks in the subscriber identity module card and the use status of the candidate memory blocks, which may specifically include the following:
step 301, according to the use state of the candidate memory block, the candidate memory block with the use state of idle state in the user identification card is used as the spare memory block.
If the user identification card stores the information address book, the information address book records the number of times of data reading and writing of the candidate storage blocks and the use state of the candidate storage blocks, so when the standby storage block needs to be determined, the candidate storage block in the idle state can be determined according to the use state of the candidate storage block recorded in the information address book, and the candidate storage block in the idle state is the standby storage block.
In one embodiment of the present application, if three candidate memory blocks are included, the three candidate memory blocks are candidate memory block a, candidate memory block B and candidate memory block C, respectively, and the usage states of candidate memory block B and candidate memory block C are idle as known from the information address book stored in the user identification card, so candidate memory block B and candidate memory block C are used as spare memory blocks.
Further, if the user identification card type does not store the information address book, or the use state of the candidate storage block cannot be obtained according to the information address book, when the standby storage block needs to be determined, the expected storage occupation duration can be determined according to the working experience of a worker; and determining whether the time difference between the last data writing start time and the current time of each candidate storage block is larger than the expected occupied time of storage, if so, taking the candidate storage block as a standby storage block, and if not, determining that the candidate storage block is not the standby storage block.
In one embodiment of the present application, if three candidate memory blocks are included, the three candidate memory blocks are candidate memory block a, candidate memory block b, and candidate memory block c, respectively; according to working experience of staff, determining that the expected storage occupation time is 1s, determining a time difference value between the last data writing start time and the current time of each candidate storage block, wherein the time difference value corresponding to the candidate storage block a is 0.5s, the time difference value corresponding to the candidate storage block B is 1.5s, and the time difference value corresponding to the candidate storage block C is 2s, so that the time difference value between the candidate storage block B and the candidate storage block C is larger than the expected storage occupation time, and taking the candidate storage block B and the candidate storage block C as standby storage blocks.
Step 302, selecting a target storage block with the least data read-write times from the standby storage blocks according to the data read-write times of the candidate storage blocks.
When the target storage block needs to be determined, the spare storage block may be sorted according to the number of data read/write times of the candidate storage block, and the target storage block with the minimum number of data read/write times may be selected from the sorted spare storage blocks.
Among these, there are many methods for sorting spare memory blocks, for example: bubbling function ordering, selection ordering, insertion ordering, hill ordering, merging ordering, etc.
In one embodiment of the present application, when it is required to select a target memory block with the least number of data read/write operations from the spare memory blocks, the following may be included: based on the bubbling function, sorting the standby storage blocks according to the data read-write times of the candidate storage blocks; and selecting a target storage block with the least data reading and writing times from the sorted standby storage blocks.
According to the data storage method, the standby storage block is determined through the use state of the candidate storage block, and the target storage block is determined from the standby storage block according to the data read-write times of the candidate storage block, so that the situation that the same storage block is frequently read-written when the user identification card writes the target data of the same type for many times is avoided.
In one embodiment, as shown in fig. 4, after the target data is written into the target storage block, the following may be further included:
in step 401, integrity verification is performed on target data written into a target storage block.
It should be noted that, when the integrity verification needs to be performed on the target data in the target storage block, the following may be specifically included: before writing target data into a target storage block, calculating a first characteristic value corresponding to the target data which is not written into the target storage block based on a verification algorithm; after the target data is written into the target storage block, calculating a second characteristic value corresponding to the target data written into the target storage block by adopting a verification algorithm; if the first characteristic value is the same as the second characteristic value, determining that the integrity verification of the target data written into the target storage block is passed; if the first characteristic value and the second characteristic value are different, determining that the integrity verification of the target data written into the target storage block is not passed.
The verification algorithm may be a hash algorithm for integrity verification, such as MD5 (Message Digest Algorithm ) algorithm, MD4 algorithm, or the like.
If the integrity verification is not passed, the target data is re-written to the target memory block, step 402.
If the integrity verification is not passed, it means that there is a special case in the process of writing the target data into the target storage block, and therefore, in order to ensure that the target data is stored in the target storage block, it is necessary to repeatedly write the target data into the target storage block.
Special cases, among others, that cause the target data to be subject to data loss may include, but are not limited to: the target data is damaged due to the wrong storage operation, the target data is lost and thinned in the process of writing into the target storage block due to network faults, the target data is attacked by viruses in the process of writing into the target storage block, the target data is lost, and the like.
Further, if the integrity verification is passed, the number of times of data reading and writing and the use state corresponding to the target storage block can be updated. Specifically, if the user identification card stores an information address book, and the information address book records the data read-write times of the candidate storage block and the use state of the candidate storage block; therefore, when the integrity verification is passed, the data read-write times and the use state corresponding to the target storage block in the information address book are updated.
In one embodiment of the present application, when the target data a is written into the target storage block a, and the integrity of the target data a is verified, one is added to the number of times of data reading and writing of the target storage block a in the information address book, and the usage state corresponding to the target storage block in the information address book is updated to be the occupied state. When the target storage block A completes the writing operation to the target data A, the use state corresponding to the target storage block in the information address book is updated to be an idle state.
According to the data storage method, the integrity of the target data written into the target storage block is guaranteed through the integrity verification of the target data written into the target storage block, and the condition that incomplete target data are stored into the target storage block is prevented.
In one embodiment, as shown in fig. 5, when the target data needs to be written into the target storage block, the following may be specifically included:
step 501, obtaining target data to be written into a subscriber identity module card.
Step 502, according to the use state of the candidate storage block, the candidate storage block with the use state of the user identification card being in the idle state is used as the standby storage block.
Step 503, based on the bubbling function, ordering the spare memory blocks according to the number of data read/write times of the candidate memory blocks.
Step 504, selecting a target memory block with the least data read-write times from the sorted standby memory blocks.
Step 505, the target data is written into the target memory block.
Step 506, performing integrity verification on the target data written in the target storage block.
If the integrity verification is not passed, step 507, the target data is re-written into the target storage block.
And step 508, updating the data read-write times and the use state corresponding to the target storage block.
According to the data storage method, according to the data reading and writing times of the candidate storage blocks and the use state of the candidate storage blocks, the target storage blocks are determined from the candidate storage blocks, and then target data to be written into the user identification card are written into the target storage blocks. According to the above-mentioned in-process can know, this application can be according to the data read-write number of times of candidate storage block and the service condition of candidate storage block, select the target storage block from candidate storage block, compare in prior art, only according to the data type of target data, store this target data in the storage block of corresponding data type, this application has avoided when user identification card write into the target data of same type many times appear the condition that frequently read-write appears in same storage block, and then, avoid causing the life reduction of user identification card even the condition that user identification card damaged.
