A Robust and Secure Way for Sharing Confidential Images

Abstract

With advent of increased Internet consumption, most of our exchanges occur through a digital medium. We share a lot of information with our family, friends, colleagues & people with whom we deal businesses & services. All this information we usually share via Smartphone's using popular messaging apps like WhatsApp or Messenger and similar social media apps. Most of these apps are secure in terms of security when it comes to informal discussions of information, but not very secure when it comes to sharing of sensitive information in form of images. Sensitive images of debit card, bank passbooks, identity cards or confidential documents usually gets stored in devices of recipient and thus can get misused knowingly or unknowingly. In this paper we discuss a robust and secure method of sharing the images (color) as well as important confidential codes in the form of images. As cases of malwares and other spywares are increasing in mobile platforms, it becomes important to address the issue where potent attackers can steal sensitive data like images stored in the device without the user's consent.
