Implementation of ID card algorithm
1. The structure of the number. Citizen identity number is a feature combination code.
It consists of seventeen-digit digital body code and one-digit verification code.
The arrangement order is from left to right: six-digit address code, eight-digit date of birth code, three-digit sequence code and one-digit verification code.
2. Address code (first six digits) represents the administrative division code of the county (city, banner, district) where the permanent residence of the coding object is located, and shall be implemented in accordance with the provisions of GB/T2260.
3. Birth date code (7th to 14th digits) represents the year, month and day of the birth of the encoded object. It is executed according to the provisions of GB/T7408. There is no separator between the year, month and day codes.
4. Sequence code (fifth to seventeenth digits)
It indicates that within the area identified by the same address code, the sequence number assigned to people born in the same year, month, and day. The odd number of the sequence code is assigned to men and even numbers are assigned to women.
5. Verification code (eighteenth digit)
(1) The weighted sum formula of the ontology code of the seventeen-digit number S = Sum(Ai Wi), i = 0, ..., 16
, first sum of the weights of the first 17 digits
Ai: indicates the number value of the ID card number at the i-th position
Wi: represents the weighting factor at the i-th position Wi: 7 9 10 5 8 4 2 1 6 3 7 9 10 5 8 4 2
(2) Calculate the modulus Y = mod(S, 11)
(3) Obtain the corresponding verification code Y through the module: 0 1 2 3 4 5 6 7 8 9 10
Verification code: 1 0 X 9 8 7 6 5 4 3 2
Address code (first six digits), I used a static variable to store all possible cities, Cities class
class Cities { static final int cities [] = { 350602, 370782, 513431, 532624, 530426, 370203, 350128, 421002, 350624, 430225, 360300, 350203, 220211, 420822, 530625, 653126, 420203, 220182, 230603,
