Double Layer Message Security For 3D Object Using Mathematical Sequences and Secret Keys

It’s It’s been so crucial lately to emphasize data security applying as the world depends on data exchange extensively almost in all domains. Steganography is one of the main techniques used to ensure information security in storage and during communication. We accomplish this novel technique by using two main layers. In the first layer, the secret message is compressed using Gzip or encrypted using Advanced Encryption Standard (AES). In the next layer, the binary representation of the secret message is embedded into vertices of x, y, and z-coordinates of the 3D object using the Gray code sequence, Recamán’s sequence, and Lucas sequence. This binary representation of secret message is embedded using the Least Significant Bit (LSB) technique according to the value of the used sequence. Different performance measurements are computed and evaluated to ensure that the 3D object quality remains preserved such as Mean Square Error (MSE), Peak Signal-to-Noise Ratio (PSNR), embedding rate (ER), Normalized Hausdorff Distance (NHD) and maximum embedding capacity. The proposed scheme is compared with its counterparts in the literature. Outstanding numerical results are achieved, showing the superiority of the proposed schemes in the terms of performance, capacity, and security.
