5. FUTURE ENHANCEMENT & CONCLUSION
Further enhancement of this work is spectral clustering algorithm will be taken for feature extraction and choose the best for to generate more compact features. Thereby, unique data can be generated as the cryptographic key. This process make comparative analysis on GLCM Algorithm features of QR image with existing different image features produced by GLCM. The cartoon image features totally differ from other images. The QR image feature most probably related to iris image. This is used to choose the best algorithm.ACKNOWLEDGEMENTSAuthors have no conflict of interest relevant to this article.
