s7: correspondingly selecting a packaging mode according to the Zx value, and correspondingly selecting a first package, a second package and a third package when Zx is respectively 1, 2 and 3; and obtaining encapsulation information after encapsulation, wherein the encapsulation information is named as a target object corresponding to the address information.
3. The medical information secure storage cooperation system based on the blockchain as claimed in claim 1, wherein the detailed step of the regression analysis in the seventh step is as follows:
s1: when Zz is not equal to 1 and is less than or equal to 4, let Gz = Zz;
s2: let Gz = Zz +1 when Zz = 1;
s3: when Zz is greater than 4, let Gz = Zz%4 when Zz%4 is greater than 1;
let Gz =2 when Zz%4= 1;
let Gz =4 when Zz%4= 0;
s4: and obtaining an updated transfer value Gz.
4. The medical information secure storage cooperation system based on the blockchain as claimed in claim 1, wherein the conversion processing in the step eight specifically comprises the steps of:
SS 01: acquiring a name character group Mi, if the name character is a Chinese character, converting the name character into a corresponding pinyin, and arranging the pinyin according to the original name character to obtain an updated name character group Mi, wherein i =1.. n;
SS 02: then, carrying out one-to-one correspondence on Mi and Hj in a mode of j + Gz = i, if j + Gz is larger than i, carrying out correspondence again in a mode of (j + Gz)% i = i, and carrying out correspondence on Mi and Hj; after corresponding, interchanging corresponding characters to obtain a new name character group and a suffix character group;
SS 03: acquiring a new name character set and acquiring an updated transfer value Gz at the same time; taking Gz characters as a group, and dividing the name character group into a plurality of inner character groups Fj, wherein j =1.. p; the p value calculation method comprises the following steps:
when n% Gz is greater than zero;
p = | n/Gz | + 1; in the formula, | n/Gz | represents that n/Gz is rounded, and the number of name characters of the last character group Fp in the group is n% Gz;
otherwise p = n/Gz;
SS 04: acquiring an inner character group Fj, making j = j +1, placing a first inner character group at the position of a second inner character group, placing the second inner character group at the position of a third inner character ancestor, sequentially replacing, and placing the position of the last inner character group at the position of the first inner character ancestor;
SS 05: obtaining a new name character set formed by all the internal character progenitors after the position adjustment;
SS 06: the new name character group and the new suffix character group are respectively used as name information and a suffix name and are placed on the packaging information again; and finishing encryption, and fusing the timestamps of the address information acquired before to obtain the two-plus-address information.
