The Image encryption is the technique which can hide the sensitive text data. In the past times, various techniques has been proposed for image encryption which are broadly into wavelet transformation and discrete transformation, In this research paper, novel technique has been proposed which is based on textual feature extraction, selection and encryption. The GLCM algorithm is applied for the textual feature analysis, PCA algorithm is used for feature selection and block wise encryption is applied to generate final stego image. The proposed algorithm is implemented in MATLAB and it has been analyzed that it performs well in terms of PSNR and MSE.
