Efficient Cancelable Iris Template Generation for Wearable Sensors

Algorithm 1

Row-wise partial sort algorithm.

INPUT: (R, m, s), where R is a row vector, m is the size of a unit-block, and s is the size of a sort-block.

OUTPUT: (), where is a partially sorted row vector.

/ 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 /
