Algorithm 1
Algorithm for encryption procedure to construct graph stego image.
1: Input: Secret Graph data(G), Cover Image(CI), AS key(k) | 2: Output: Graph Stego Image | 3: procedure Encryption | 1. Write the adjacency matrix of the given graph data which is of order . | 2. Find such that | 3. Apply relation of AS over (as defined in Theorem 1) on to obtain the cipher graph data . | 4. Store the number of nodes at the first bits of . | 5. Store the bits of the encrypted data at the remaining LSB of the RGB components of the . | 4: end procedure |
