AbstractMultiple secret sharing algorithm using the YCH scheme, combined with DNA encoding is proposed, focusing at better security. Firstly, DNA encoding for multiple images is carried out; then the addition of these encoded components by DNA is performed. Secondly, the (t, n) scheme used the Lagrange interpolation polynomial to share these DNA scrambled matrices is performed. Thirdly, these shares are embedded using a modular operation. Finally, ‘t’ or more shares are pooled which reconstructs the scrambled matrices, and by decoding the DNA scrambled matrices multiple secrets are reconstructed without loss. The simulation results and the security analysis prove that this algorithm is perfect, and produces results with better PSNR value. The correlation co- efficient shows that this also has the ability of resisting various attacks.
