For example, personal photos are stored on our cell phones, portable devices, computers, etc. Since these photos must remain private, we encrypt them. A text file has the same meaning for today's user. It should be kept securely on a cloud server. Digital photos must be protected during transmission, but copies of personally identifiable information such as panoramic cards, passports, ATM cards, etc. must be protected. Must be registered on wnpc. To reduce duplication in our proposed system, we protect text files and image data.
