The creation of Multimedia images and files has been increasing day by day that in turn leads to suspicious acts and threats. Many research works have been preceded for the same. In the recent works, confidential mage data security based on encryption and watermark (CIDSEW) was proposed in which security features. Here, secrecy information is incorporated with the images, to be shared through watermarking technique. Nevertheless, it doesn’t give a secure way for access restriction when it goes for multiple users because the encryption algorithm used implants the whole image which weakens the functioning where the sensitive parts of the images can’t be centered approximately. The major aim of the proposed work is to introduce a new security algorithm for secure sharing of text via the watermark image. In order to overcome the restrictions in the existing technique, the novel approach namely Secured and Attribute based User access control (SA-UAC) methodology has been presented in the proposed work. The proposed work is done in MATLAB which demonstrates that the proposed work prompts the preferred result. The results of the proposed and existing methods are measured in terms of Peak Signal-To-Noise Ratio (PSNR), Mean Square Error (MSE) and Correlation.
