Aadhar card number verification in the app

Question

we are developing an application that should check whether the user enters a valid "AADHAR" number or not. I find some links and some "apis" but do not meet the final requirements, please provide me with useful material to solve this problem.

What is Aadhaar?

Aadhaar is a 12-digit individual identification number issued by India to identify India on behalf of the Government of India.

Answer 1

I think you are looking for the Verhoeff algorithm because UIDAI uses this algorithm to check the aadhar number. You just need to create and use the below class.

 class VerhoeffAlgorithm{ static int[][] d = new int[][] { {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}, {1, 2, 3, 4, 0, 6, 7, 8, 9, 5}, {2, 3, 4, 0, 1, 7, 8, 9, 5, 6}, {3, 4, 0, 1, 2, 8, 9, 5, 6, 7}, {4, 0, 1, 2, 3, 9, 5, 6, 7, 8}, {5, 9, 8, 7, 6, 0, 4, 3, 2, 1}, {6, 5, 9, 8, 7, 1, 0, 4, 3, 2}, {7, 6, 5, 9, 8, 2, 1, 0, 4, 3}, {8, 7, 6, 5, 9, 3, 2, 1, 0, 4}, {9, 8, 7, 6, 5, 4, 3, 2, 1, 0} }; static int[][] p = new int[][] { {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}, {1, 5, 7, 6, 2, 8, 3, 0, 9, 4}, {5, 8, 0, 3, 7, 9, 6, 1, 4, 2}, {8, 9, 1, 6, 0, 4, 3, 5, 2, 7}, {9, 4, 5, 3, 1, 2, 6, 8, 7, 0}, {4, 2, 8, 6, 5, 7, 3, 9, 0, 1}, {2, 7, 9, 3, 8, 0, 6, 4, 1, 5}, {7, 0, 4, 6, 9, 1, 3, 2, 5, 8} }; static int[] inv = {0, 4, 3, 2, 1, 5, 6, 7, 8, 9}; public static boolean validateVerhoeff(String num){ int c = 0; int[] myArray = StringToReversedIntArray(num); for (int i = 0; i < myArray.length; i++){ c = d[c][p[(i % 8)][myArray[i]]]; } return (c == 0); } private static int[] StringToReversedIntArray(String num){ int[] myArray = new int[num.length()]; for(int i = 0; i < num.length(); i++){ myArray[i] = Integer.parseInt(num.substring(i, i + 1)); } myArray = Reverse(myArray); return myArray; } private static int[] Reverse(int[] myArray){ int[] reversed = new int[myArray.length]; for(int i = 0; i < myArray.length ; i++){ reversed[i] = myArray[myArray.length - (i + 1)]; } return reversed; } }

Use this javascript

 // multiplication table d var d = [ [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [1, 2, 3, 4, 0, 6, 7, 8, 9, 5], [2, 3, 4, 0, 1, 7, 8, 9, 5, 6], [3, 4, 0, 1, 2, 8, 9, 5, 6, 7], [4, 0, 1, 2, 3, 9, 5, 6, 7, 8], [5, 9, 8, 7, 6, 0, 4, 3, 2, 1], [6, 5, 9, 8, 7, 1, 0, 4, 3, 2], [7, 6, 5, 9, 8, 2, 1, 0, 4, 3], [8, 7, 6, 5, 9, 3, 2, 1, 0, 4], [9, 8, 7, 6, 5, 4, 3, 2, 1, 0] ]; // permutation table p var p = [ [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [1, 5, 7, 6, 2, 8, 3, 0, 9, 4], [5, 8, 0, 3, 7, 9, 6, 1, 4, 2], [8, 9, 1, 6, 0, 4, 3, 5, 2, 7], [9, 4, 5, 3, 1, 2, 6, 8, 7, 0], [4, 2, 8, 6, 5, 7, 3, 9, 0, 1], [2, 7, 9, 3, 8, 0, 6, 4, 1, 5], [7, 0, 4, 6, 9, 1, 3, 2, 5, 8] ]; // inverse table inv var inv = [0, 4, 3, 2, 1, 5, 6, 7, 8, 9]; // converts string or number to an array and inverts it function invArray(array) { if (Object.prototype.toString.call(array) === "[object Number]") { array = String(array); } if (Object.prototype.toString.call(array) === "[object String]") { array = array.split("").map(Number); } return array.reverse(); } // generates checksum function generate(array) { var c = 0; var invertedArray = invArray(array); for (var i = 0; i < invertedArray.length; i++) { c = d[c][p[((i + 1) % 8)][invertedArray[i]]]; } return inv[c]; } // validates checksum function validate(array) { var c = 0; var invertedArray = invArray(array); for (var i = 0; i < invertedArray.length; i++) { c = d[c][p[(i % 8)][invertedArray[i]]]; } return (c === 0); } $(document).ready(function () { $('#UserForm').formValidation({ message: 'This value is not valid', feedbackIcons: { valid: 'glyphicon glyphicon-ok', invalid: 'glyphicon glyphicon-remove', validating: 'glyphicon glyphicon-refresh' }, fields: {aadhaar_no: { validators: { digits: { message: 'Please use numeric characters only.' }, stringLength: { min: 12, max: 12, message: 'The aadhaar number must be 12 characters long' }, identical: { field: 'c_aadhaar_number', message: 'The aadhaar number and its confirm field are not the same' }, callback: { message: 'The input string is not a valid Aadhaar number.', callback: function (value, validator, $field) { return validate(value); } } } } }); });

Try it.

 function validateAadhaar1(fieldData){ console.log(fieldData.id); var lengthOfAadhaar = fieldData.value; var checkDigits = /^\d+$/.test(lengthOfAadhaar); var zero = /.!=000000000000/.test(lengthOfAadhaar); var one = /.!=111111111111/.test(lengthOfAadhaar); var two = /.!=222222222222/.test(lengthOfAadhaar); var three = /.!=333333333333/.test(lengthOfAadhaar); var four = /.!=444444444444/.test(lengthOfAadhaar); var five = /.!=555555555555/.test(lengthOfAadhaar); var six = /.!=666666666666/.test(lengthOfAadhaar); var seven = /.!=777777777777/.test(lengthOfAadhaar); var eight = /.!=888888888888/.test(lengthOfAadhaar); var nine = /.!=999999999999/.test(lengthOfAadhaar); if(lengthOfAadhaar.length!=12 || checkDigits == false || zero == false || one ==false || two ==false || three == false || four == false || five == false || six == false || seven == false || eight == false || nine == false) { document.getElementById(fieldData.id).style.color = "#ff0202"; return false; } else{ document.getElementById(fieldData.id).style.color = "#555"; } return true; }
