Hiding Secret Data Using AES Encryption and DFS Graph Traversal in 3D Images

3D models have taken centre stage in a variety of applications across numerous industries as a outcome of the enormous advancements in multimedia communications. As a result, these images are used in steganography as safe and trustworthy cover media for hiding secret data. The confidential material in this document is encrypted using the AES technique for increased protection. Next, using depth first search, a geometric domain oriented steganography technique is used, in which triangular meshes' each vertex of several 3D images are subtly altered to hold the hidden data. A geometrical attack on a 3D model, such as translation, uniform scaling, or rotation, is found to be resistant to our proposed method. Also, it is capable of blindly disclosing the confidential information. Our proposed algorithm's 9 bpv embedding performance is evaluated and contrasted with compare to existing literature. The numerical results oblige as an excellent benchmark for higher payload data security solution.
