Secret image sharing is a security technique which plays its role in multi-user environment. Secret image sharing using binary operation is a fast and lightweight technique but partial information leakage from the shares or less than threshold number of shares is the main disadvantage; to prevent which image encryption is adopted as a preprocessing step. This invites the burden of securely sending encryption key to get the image decrypted. In this paper, a lossless threshold secret image sharing using bitwise OR operation is proposed. As a preprocessing step the secret image is encrypted using chaotic logistic map taking information entropy as the key. The important advancement of the technique is that the encryption key need not required to be transmitted to the combiner side. Experimental results produce noise like image and MSE and PSNR value of the shares say in support of that. NPCR value found by comparing the retrieved image from less than threshold number of shares with the test image is more than 99%, and this signify no visual similarity with the original image. Comparative analysis with some state of the art techniques provides the proposed method a platform in secret image sharing.
