Graph Crypto-Stego System for Securing Graph Data Using Association Schemes
Algorithm 2
Algorithm for extracting secret data from graph stego image.
1: Input: Graph Stego Image(GSI), AS key(k) | 2: Output: Secret Data retrieved | 3: procedure Decryption | 1. Obtain the hidden data and number of nodes from RGB components of the GSI. | 2. Find decryption key as discussed in Theorem 1 from key . | 3. Find such that . | 4. Apply relation of AS over (as defined in Theorem 1) on to obtain decrypted graph data. | 4: end procedure |
