Efficient Cancelable Iris Template Generation for Wearable Sensors

Algorithm 2

Column-wise partial sort algorithm.

INPUT: (X, m, s), where X is a IrisCode, m is the size of a unit-block, and s is the size of a sort-block.

OUTPUT: (), where is a partially sorted IrisCode.

/ for each sort-block, sort out the unit-blocks /

  / initialize the arrays of m-bit integer variables /

   / for each unit-block, make an integer for the unit-block /

   / replace the unsorted sort-block with the sorted sort-block /
