Computer science and Engineering

Abstract— The expanding enthusiasm for gathering and distributing a lot of people information open for various purposes. For example, therapeutic research, showcase examination and practical measures have made significant security worries about people delicate data. To manage these worries, numerous privacy-preserving data publishing (PPDP) systems have been proposed in writing. In proposed system, the admin decides to design a smart examination system which should be conducted online. Initially, the admin allocates ten question papers for the exam. After allocation, these files should be in an encrypted form. For every file, different key will be generated and the entire folder will have single key to access .The admin shares the file to the college then they get an encrypted file as a key. This system uses a automatic technique for selecting keys randomly. That key will be merged in a QR code and if the student has registered in that college ,they can login and scan that QR code and get the key. If the entered key is correct then a request is sent to the admin. In respect to that key the admin will send the file to the student.
