It is recommended to provide logistic support to the armed forces constantly thereby keeping them informed of the ground situation and alert them in advance to acquire an advantage. Surveillance is achieved via satellite imaging. Such confidential images captured are to be transmitted in real time securely to avoid any third party from interpreting them. This can be obtained by utilizing Visual Cryptography. Visual Cryptography secret image sharing ensures security of the transmitted information by splitting a secret image into n shares which are owned by n participants to prevent the secret from accidentally being lost. Existing algorithms provide solutions for problems such as secret information leaking from shares, attack on share images and large share image issues but their time complexity is still debatable. Therefore, the proposed Quadri directional search algorithm technique can be implemented for encrypting the information.
