An Effectual Hybrid Approach Using Data Encryption Standard (DES) and Secured Hash Algorithm (SHA) for Image Steganography

Today Security of data is of foremost importance in today’s world. Security has become one of the most important factor in communication and information technology. For this purpose steganography is used. Steganography is the art of hiding secret or sensitive information into digital media like images so as to have secure communication. In this paper we present and discuss LSB (Least Significant Bit) based image steganography with DES SHA algorithm so as to provide an extra layer of security

Changes That Should Remain in Higher Education Post COVID-19: A Mixed-Methods Analysis of the Experiences at Three Universities

Objectives: The goal of the present study is to describe how the transition to remote emergency delivery was addressed in three universities during the COVID-19 pandemic, to determine the satisfaction levels of their students and faculty with this new teaching-learning experience, and to gather their opinions about the future of higher education. Method: The study uses a mixed-methods approach, including faculty and student surveys and focus groups Results: The study shows high satisfaction with the emergency remote delivery and clearly reflects the relevance of enhancing the digital components of future learning experiences in higher education and a unanimous preference for hybrid education. Participants provide recommendations to institutions regarding what students and faculty would like to keep for a more effective learning experience when the new normal comes. Conclusions: COVID-19 has had terrible consequences; however, the pandemic has brought along some positive effects and improvement opportunities in higher education, and, if the results of the present study are any indication, the future of face-to-face higher education should be hybrid. Implication for Theory and/or Practice: The study results can provide recommendations and inform decision-making by institutional leaders and policy makers regarding the necessary enhancement of the digital component of the teaching and learning process in higher education
