secure_inner_join.utils.randomize_ndarray(arr)

Randomize all elements in a numpy array with ciphertexts.

This function calls ‘RandomizableCiphertext.randomize’ ‘arr.size’ times, as expected. Note that this contrasts with the ‘arr.size+1’ calls made by ‘np.vectorize(lambda _: _.randomize())(arr)’.

Parameters:

arr (ndarray[Any, dtype[object_]]) – array to be randomized

Return type:

None
