Algorithm 2: Data Embedding

Input: Sharing images C(t), $t=1, 2, \dots , n$, Data S(t)

Output: Marked sharing images C′(t)$, t=1, 2, \dots , n$

Step 1: For a pixel C(t)i,j of Sharing images C(t), the message is taken from the secret message S(t) and embedded in the B part of pixel C(t)i,j.

Step 2: Repeat Step 1 until all the B parts of C(t)i,j are embedded in the secret message.

Step 3: The output of the embedded shared image C′(t).
