Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
FIG. 1 is a diagram of an application environment of a data caching method in one embodiment. Referring to fig. 1, the data caching method is applied to a data caching system. The data caching system comprises a terminal 110 and a server 120, wherein the terminal 110 is connected with the server 120 through a network. The terminal 110 may be a fixed terminal, which may specifically be at least one of a printer, a scanner, and a monitor, or a mobile terminal, which may specifically be at least one of a tablet, a smartphone, a personal data assistant, and a digital camera.
As shown in fig. 2, in an embodiment, a data caching method is provided, which is exemplified by applying the method to the server 120 in fig. 1, and the method specifically includes the following steps:
s202, analyzing the received service data caching request, and extracting service data and a service identifier in the service data caching request through analysis.
Specifically, the terminal 110 displays a service page, periodically acquires service data and a service identifier, and sends the acquired service data and service identifier to the server 120.
In an embodiment, the terminal 110 periodically obtains the service data and the service identifier in the displayed service page, generates a service data caching request according to the obtained service data and the service identifier, and sends the service data caching request to the server 120. The server 120 parses the received service data caching request, and extracts the service data and the service identifier in the service data caching request through parsing.
And S204, determining the pixel size of the cache picture according to the preset image parameter digit and the character digit obtained by counting the service data.
Specifically, after the server 120 acquires the service data, the number of character bits of the service data is counted, and the counted number of character bits is divided by the number of preset image parameter bits to obtain the pixel size of the cache picture.
In one embodiment, the cached picture pixel size includes a cached picture pixel width and a cached picture pixel height, and the cached picture pixel height is a preset value. The server 120 divides the character bit number of the statistical service data by the preset image parameter bit number to obtain the pixel width of the cache picture.
For example, if the predetermined image parameters are in RGBA format, where RGBA represents Red (Red), Green (Green), Blue (Blue), and Alpha (transparency or opacity), the number of bits of the predetermined image parameters is 4. The pixel height of the cache picture is preset to be 1 pixel, the service data is "12345678", the number of character bits of the counted service data is 8, 2 is obtained by dividing 8 by 4, and 2 is the pixel width of the cache picture.
And S206, coding the service data to obtain a pixel parameter array.
Specifically, the server 120 encodes each character in the service data, converts each character into a corresponding pixel parameter through encoding, and obtains a pixel parameter array according to the pixel parameter corresponding to each character.
For example, the service data "12345678" is encoded, each bit of character in the service data is encoded by encoding, so that "51" is obtained by encoding "1", "102" is obtained by encoding "2", "153" is obtained by encoding "3", "204" is obtained by encoding "4", "55" is obtained by encoding "5", "106" is obtained by encoding "6", "157" is obtained by encoding "7", and "208" is obtained by encoding "8", the value of the pixel parameter obtained by encoding is between 0 and 255, and the obtained pixel parameter array is {51, 102, 153, 204, 55, 106, 157, 208 }.
And S208, reading the pixel parameters from the pixel parameter array in sequence according to the preset image parameter digit.
Specifically, the server 120 reads a corresponding number of pixel parameters from the pixel parameter array in sequence according to the preset image parameter bits.
For example, the number of bits of the image parameter in the RGBA format is 4, and the 4 pixel parameters are read from front to back according to the array sequence in the pixel parameter array. The pixel parameter array is {51, 102, 153, 204, 55, 106, 157, 208}, the {51, 102, 153, 204} is read, the read {51, 102, 153, 204} is used as RGBA pixel parameters of the first pixel, the first pixel is constructed according to the read {51, 102, 153, 204}, the {55, 106, 157, 208} is read, the {55, 106, 157, 208} is used as RGBA pixel parameters of the second pixel, the second pixel is constructed according to the read {55, 106, 157, 208}, and a cache picture is obtained according to the first pixel and the second pixel.
And S210, generating a cache picture matched with the pixel size of the cache picture according to the read pixel parameters, and adding the service identifier into the cache picture.
Specifically, the server 120 reads the number of pixel parameters equal to the number of bits of the preset image parameter each time, constructs one pixel according to the pixel parameter read each time, forms a cache picture matched with the pixel size of the cache picture according to the constructed pixel, and adds the service identifier as a picture identifier to the cache picture.
S212, inquiring a cache space corresponding to the service identifier, and storing the cache picture added with the service identifier to the inquired cache space.
Specifically, after generating the cache picture, the server 120 queries the cache space corresponding to the service identifier, and stores the cache picture and the service identifier in the queried cache space correspondingly.
In one embodiment, the server 120 adds the service identifier to the cached image, queries a cached space corresponding to the service identifier, and caches the cached image to which the service identifier is added to the queried cached space.
In this embodiment, the acquired service data is encoded, a pixel parameter array is obtained through encoding, a cache picture is drawn according to pixel parameters in the pixel array, and the cache picture and the service identifier are stored in a cache space correspondingly. The cached pictures are cached in the caching space by drawing the cached data into the cached pictures in a coding mode, so that the leakage of the service data is avoided, and the caching safety of the service data is improved.
As shown in fig. 3, in an embodiment, the step S204 specifically includes a step of determining a pixel size of the cached picture, where the step specifically includes the following steps:
s302, obtaining an encryption mode corresponding to the service identifier.
Specifically, the server 120 stores an encryption mode corresponding to each service identifier. The server 120 queries the encryption scheme corresponding to the service identifier from the stored encryption schemes, and obtains the queried encryption scheme.
S304, encrypting the service data according to the obtained encryption mode to obtain a service data ciphertext.
Specifically, after obtaining the encryption mode corresponding to the service identifier, the server 120 encrypts the service data by using the obtained encryption mode to obtain a service data ciphertext.
S306, counting the character digit of the business data ciphertext.
Specifically, the server 120 counts the number of character bits of the service data ciphertext with respect to the service data ciphertext obtained by the encryption.
And S308, determining the pixel size of the cache picture according to the counted character bit number and the preset image parameter bit number.
Specifically, the server 120 divides the counted number of the character bits by the number of the preset image parameter bits, and if the obtained quotient is an integer, the integer is taken as the cache picture pixel width in the cache picture pixel size; if the obtained quotient has a remainder, rounding and adding 1 to obtain the pixel width of the cache picture; and determining the pixel size of the cached picture according to the calculated width of the picture pixel and the preset height of the picture pixel.
For example, if the service data ciphertext is "12345678", the preset image parameter bit number is 4 bits, the character bit number of the service data ciphertext counted by the server 120 is 8, 2 is obtained by dividing 8 by 4, and the cache picture pixel width in the cache picture pixel size is 2; if the service data ciphertext is "123456789", the preset image parameter bit number is 4 bits, the number of character bits of the service data ciphertext counted by the server 120 is 9, 2 or more is obtained by dividing 9 by 4, and the width of the cache picture pixel in the cache picture pixel size is 2 plus 1 is 3.
In this embodiment, the service data is encrypted according to the encryption mode corresponding to the service identifier to obtain a service data ciphertext, the pixel size of the cache picture is determined according to the number of character bits of the service data ciphertext, the service data ciphertext is converted to be matched with the pixel size of the cache picture, and the security of the service data is improved by encrypting the service data.
In one embodiment, S212 specifically includes the following: inquiring whether a cache picture corresponding to the service identifier exists in a cache space; and if so, deleting the inquired cache picture, and correspondingly storing the generated cache picture and the service identifier.

The server 120 receives the cache data acquisition request sent by the terminal 110.
S404, inquiring the cache picture from the cache space according to the service identifier in the cache data acquisition request.
Specifically, the server 120 parses the cache data acquisition request after receiving the cache data acquisition request, extracts the service identifier in the cache data acquisition request by parsing, and queries a cache picture from the cache space according to the extracted service identifier.
And S406, returning the inquired cache picture to the terminal.
