Algorithm 1: IP Marks embedding the algorithm

Input: (i) Position

P_{n}

(ii) Marks sequence

W

Output: (i) Pseudo position

L_{n}

(ii) Constraint function

H W_{x y}

/*Marks sequence

W = {w_{0}, w_{1}, w_{2}, \dots, w_{n}}

L

means that

P

after the Marks sequence is embedded, the virtual position generated by the constraint

H W_{x y}

*/
/*

C_{n}

represent unused resource sequence

C_{n}

*/
1: Single location information

P_{i}

selected from

C_{n}

;
2: Calculate

H W_{x y}

by Constraint function

H F_{a b}

and

P_{i}

;
3: Calculate Single pseudo location information

L_{i}

by Constraint function

H W_{x y}

and

P_{i}

;
4: If

L_{i} \in C_{n}

then
5. Store location information

P_{i}

and

L_{i}

;
6: Else if

L_{i} \notin C_{n}

then
7: Delete the element

P_{i}

from the collection

P_{n}

;
8: End If
9: Store

P_{i}

P_{n}

;
10: For i:= 0 to

n

11: Embed

w_{i}

into Location

P_{i}

P_{n}

;
12: End For
13: Output

L_{n}

and

H W_{x y}
