[0028] Please refer to Figure 1 , Figure 1 The flowchart of the intelligent terminal data compression anti-redundancy interaction method provided by the embodiment of the application is shown in the figure.

[0029] As Figure 1 shown, the method comprises steps S101-S105.

[0030] S101, obtain the unique code of the card end, and encrypt the unique code by an encryption algorithm to generate a corresponding string key, wherein the string key comprises a unique table header rule value and a table header identifier;

[0031] S102, check the unique table header rule value against the local table header index total library rule library;

[0032] S103, if the unique table header rule value conforms to the local table header index total library rule library, compress the table header identifier to obtain a compressed marker code;

[0033] S104, quickly compare the compressed marker code with the local database, if a hit is obtained, extract the corresponding local data, if no hit is obtained, query the corresponding data from the cloud according to the table header identifier, and receive the data returned by the cloud;

[0034] S105, obtain the update data issued by the cloud according to the timing mechanism and perform data update, wherein the update data is the data deleted by the cloud from the target data stored locally by another intelligent terminal.

[0035] In this embodiment, the card end includes but is not limited to an IC card, a CPU card, and an NFC handheld device.

[0036] In a specific use scenario, the user brings the IC card / CPU card / NFC handheld device close to the intelligent terminal to perform card swiping. The intelligent terminal first acquires the unique code of the card terminal, then encrypts the unique code by using an encryption algorithm to generate a string key corresponding to the card terminal, and then checks the string key based on a pre-constructed local table header index total rule library. If the check fails, it indicates that the card terminal is a non-system authorized card, and a prompt message such as "authentication failure" is displayed on the display screen of the intelligent terminal. If the check succeeds, it indicates that the card terminal is a system authorized card, and the table header identifier is compressed to obtain a compressed marker code. It should be noted that the compression of the table header identifier can effectively reduce the number of strings in the table header identifier, thereby improving the retrieval efficiency. Then the intelligent terminal performs a quick comparison between the compressed marker code and the local database. If a hit is found, it indicates that the local database stores the basic information of the card terminal, and the basic information of the card terminal can be directly called from the local database and displayed on the display screen of the intelligent terminal. If no hit is found, it indicates that the local database does not store the basic information of the card terminal, so the basic information of the card terminal needs to be retrieved from the cloud and displayed on the display screen of the intelligent terminal.

[0037] At the same time, in order to reduce the occurrence of data redundancy, a timing mechanism is established in advance, for example, in the non-busy meal time period of "10:00-11:00", "14:00-16:30", "00:00-04:00", etc., the cloud automatically issues update data to the intelligent terminal, for example, the cloud updates data to the A intelligent terminal, and also updates data to the B intelligent terminal. The difference is that the target data to be stored is stored in the A intelligent terminal, and the target data originally stored in the B intelligent terminal is deleted, so as to ensure that the target data can only be stored in one intelligent terminal, thereby optimizing the local data of the B intelligent terminal and reducing the redundant data of the B intelligent terminal.

[0038] For example, the C card terminal originally bound with the A intelligent terminal is reconfigured to be bound with the B intelligent terminal. The cloud will issue different data update requests to the A intelligent terminal and the B intelligent terminal, specifically, a deletion request to delete the basic information of the C card terminal is issued to the A intelligent terminal. Based on the deletion request, the A intelligent terminal deletes the basic information originally stored in the local database of the A intelligent terminal and updates its own local database. The cloud issues the basic information of the C card terminal to the B intelligent terminal. The B intelligent terminal receives and stores the basic information of the C card terminal and updates its own local database. At the same time, the cloud updates the data version information of the intelligent terminal.

[0039] The first aspect of the application encrypts the unique code of the card end by algorithm, which can improve the security of the intelligent terminal and reduce the occurrence of being used by a third party; the second aspect of the application compares the compressed mark code in the local database, which can effectively improve the comparison efficiency, ensure the normal reading and storage of data, and ensure the timeliness of data response; the third aspect of the application updates the data of each intelligent terminal by using the cloud, optimizes the local database of each intelligent terminal, and avoids the occurrence of data redundancy.

[0040] In a specific embodiment, the string key further includes a device number of the intelligent terminal and update check information, and the update check information includes update records for recording update information and check information for checking the local model of the intelligent terminal.

[0041] In the embodiment, the application pre-establishes an index tag mechanism in the cloud or background: "index total table: device number library: non-local data: local data: update mechanism".

[0042] The index total table is used to record each piece of data and establish a total index table rule, which conforms to the HMAC-SHA256 algorithm encryption Key rule, for example, the encryption Key is 1B2C3D: 123456, that is, the encryption Key is composed of the encryption rule + enterprise user data starting number range (1-99999999). It should be noted that the encryption Key of each enterprise or factory is unique.

[0043] The device number library is used to establish a one-to-one correspondence between the intelligent terminal and "non-local data: local data: update mechanism" device number library, so as to quickly match data information and data calling, recording, etc. Specifically, the device number library stores the unique code corresponding to n card ends.

[0044] The non-local data is mainly used to store local non-high-frequency data (redundant data);

[0045] The local data is mainly used to store local high-frequency data;

[0046] The update mechanism is used to update the local data model according to the "timing mechanism", and the incremental 0.1 is used to record the relevant iteration version number, for example: A1.1 is used to record the index total table version number, and the next version number is A1.2; B1.1 is used to record the update mechanism version number, and the next version number is B1.2.

[0047] In addition, the application pre-establishes a data compression anti-redundancy operation model in the local database of the intelligent terminal. The data compression anti-redundancy operation model is used to store a table header index total library rule library table, local table header library table data and high-frequency user data (L2 queue in Two Queues cache). Specifically, the data compression anti-redundancy operation model is "intelligent terminal device number: table header index total library rule library table: local table header library table data: update mechanism". It should be noted that the local table header library table data is the stored user basic data. The data compression anti-redundancy operation model enables the intelligent terminal to quickly match data information, thereby improving user experience comfort.

[0048] In one embodiment, the step S101 includes the following steps:

[0049] S10, obtain the unique code of the card end, and encrypt the unique code by using a target key based on an HMAC-SHA256 encryption algorithm to generate a string key.

[0050] In this embodiment, after obtaining the unique code of the card end, the intelligent terminal inputs the unique code into the data compression anti-redundancy operation model. The data compression anti-redundancy operation model encrypts the unique code by using a target key based on an HMAC-SHA256 encryption algorithm to generate a 32-bit string key. For example, if the unique code of the card end is HWD0000000010001: HWDABC000ABC0ABC, the 32-bit string key obtained after encryption is "789fdmfd k92jg819, 3mf123m8, fjis, 2340". It should be noted that "789fdmfd k92jg819" represents a unique table header rule value, "3mf123m8" represents a table header identifier, "fjis" represents an intelligent terminal device number, and "2340" represents update verification information, which is used to verify whether the local compression model of the "fjis" intelligent terminal is the latest version.

[0051] It should be noted that if the card end and the fjis smart terminal are to be unbonded, only the unique code needs to be changed in the background. The 32-bit string key generated after the encryption of the newly generated unique code will change from "789fdmfd k92jg819, 3mf123m8, fjis, 2340" to "789fdmfd k92jg819, 3mf123m8, M, 2341", which represents that the card end is bound with the M smart terminal. At this time, the cloud sends a deletion request to delete the basic information of the card end to the fjis smart terminal according to the timing mechanism, updates the local database of the fjis smart terminal, and issues the basic information of the card end to the M smart terminal. The M smart terminal receives the basic information of the card end and stores and updates the local data itself. It is worth noting that the application updates the unique code each time and increments the update check information by 1, that is, "2340" becomes "2341" as shown above. That is, the cloud records the information of each update to manage the version update well.

[0052] In step S102, it is judged whether the unique table header rule value "789fdmfd k92jg819" is within the range allowed by the local table header index total library rule library. If it is within the running range, it is determined that the check is passed, otherwise it is not passed.

[0053] In a specific embodiment, the step S103 includes the following steps:

[0054] S20, traverse the local table header index total library rule library, judge whether the local table header index total library rule library exists the target rule value same with the unique table header rule value, if not exists, execute step S21, if exists, execute step S22;

[0055] S21, end and output the check result;

[0056] S22, based on the HMAC-SHA256 encryption algorithm, encrypt the table header identifier by using the target key, to generate a compressed marker code.

[0057] In the embodiment, the data compression anti-redundancy operation model first checks the 32-bit string key and the local table header index total library rule library. The specific check is as follows: extract the unique table header rule value "789fdmfd k92jg818" in the 32-bit string key, judge whether the local table header index total library rule library exists the unique table header rule value, if exists, it means that the card end is a system authorized card, the check is passed, and the operation set is output as {true}, if not exists, it means that the card end is a non-system authorized card, the check is not passed, the operation set is output as {false}, and the operation is stopped.

[0058] In case of passing the verification, the application is based on the HMAC-SHA256 encryption algorithm again, and the table header identifier is encrypted by the target key to generate a compressed marker code, for example, the table header identifier "3mf123m8" is encrypted and compressed into a 4-bit compressed marker code "oaA1". Compared with the 8-bit character table header identifier, the 4-bit compressed marker code can improve the search efficiency by more than one time. It should be noted that the compressed marker code is preferably composed of application numbers and uppercase and lowercase letters.

[0059] In a specific embodiment, the step S104 includes the following steps:

[0060] S30, the compressed marker code is matched with the local database in range, if the compressed marker code is in the matching range, step S31 is executed, if the compressed marker code is not in the matching range, step S32 is executed;

[0061] S31, reading the table header of the card end, and positioning and extracting the corresponding local data based on the table header of the card end and outputting;

[0062] S32, reading the table header of the card end, and sending query information to the cloud end, so that the cloud end retrieves the cloud database based on the table header of the card end in the query information and returns the corresponding data, so that the smart terminal receives the data returned by the cloud end and outputs.

[0063] In this embodiment, the local database of the smart terminal is traversed to determine whether the local database exists "oaA1", if "oaA1" exists, it means that the local database exists the basic information of the card end, so the output operation set is {true, oaA1, 1}, and the table header of the card end is read, for example, 0aa0, and the output operation set is {true, oaA1, 1, 0aa0}, then the 0aa0 data in the L2 queue (LRU queue) of the local database (Two Queues cache) is quickly positioned and extracted, and the 0aa0 data is displayed on the display screen of the smart terminal.

[0064] It should be noted that the query information of the application includes the table header of the card end + the device number + the version number of the smart terminal, the cloud end quickly locates the data corresponding to the table header of the card end, finds the table where the device number of the smart terminal is located, and then issues the corresponding data to the smart terminal, while the cloud end synchronously updates the version number.

[0065] If there is no "oaA1", it indicates that the local database does not have the basic information of the card end, so it is necessary to request data from the cloud, and the specific process is as follows: the smart terminal obtains the table header of the card end, and sends query information to the cloud, the cloud receives the query information, and based on the table header "0aa0" of the card end, searches in the cloud database, and returns the searched data to the smart terminal, and the smart terminal displays the data on the display screen after receiving the data.

[0066] In a specific embodiment, the step S31 comprises the following steps:

[0067] S40, read the table header of the card end, and based on the table header of the card end, locate and extract the corresponding local data from the L2 queue of the local cache, and update the L2 queue order synchronously.

[0068] It should be noted that the data compression and redundancy prevention operation model of the present application is based on the Two Queues cache algorithm, including L1 queue (FIFO queue) and L2 queue (LRU queue). When the data is accessed for the first time, the Two Queues cache algorithm caches the data in the FIFO queue. If the data has not been accessed again in the FIFO queue, it will be eventually eliminated according to the FIFO rule; if the data is accessed again in the FIFO queue, the data will be moved to the head of the LRU queue; if the data is accessed again in the LRU queue, the data will be moved to the head of the LRU queue, and the data located at the tail of the LRU queue will be eliminated, thereby reducing the data redundancy.

[0069] Since the local database has the table header "0aa0" of the card end, it indicates that the basic information of the card end has been stored in the L2 queue, so the smart terminal only needs to find the 0aa0th data in the L2 queue.

[0070] In a specific embodiment, the step S32 comprises the following steps:

[0071] S50, read the table header of the card end, and according to the table header of the card end, send query information to the cloud, so that the cloud decrypts the table header of the card end, and searches in the cloud database and returns the corresponding data;

[0072] S51, the smart terminal receives the data returned by the cloud and outputs, and simultaneously updates the L1 queue order of the local cache.

[0073] In the embodiment, since the local database does not exist the card end table header "0aa0", it is indicated that the local database has not stored the basic information of the card end before, the output operation set is {true, oaA1, 0, 0aa0}, and the intelligent terminal needs to send the query information to the cloud end. The cloud end decrypts the table header "0aa0" of the card end based on the query information, retrieves the cloud end database by using the decrypted data, extracts the retrieved data and sends the data to the intelligent terminal. The intelligent terminal receives the data, stores the data into the L1 queue and displays the data on the display screen, and updates the L1 queue.
