- 2. OUTLINE Summary: 1.Introduction -Password -Authentication -Methods of Authentication 2. Text-based password -Drawbacks of text-based passwords 3.Problem Definition 4.Graphical Password 5.Existing Model 6.Proposed Model 7.Conclusion
- 3. INTRODUCTION What is PASSWORD?
- 4. PASSWORD PASSWORD is a secret word or string of characters that is used for user authentication to prove his/her identity and going to access resources Used for? Logging into accounts Retrieving emails Accessing applications Used In? Networks. Websites Databases
- 5. What is AUTHENTICATION? Conformation of a person’s identity
- 6. Methods for authentication Token-based Biometric-based Knowledge-based Key cards, smart cards Face recognition, finger print Text-based, image-based
- 8. Drawbacks 1) Difficulty of remembering passwords Easy to remember : easy to guess Hard to guess : hard to remember 2)Users tend to write the passwords down or use the same passwords by different accounts
- 9. Drawbacks 3)Brute force attack 4) Dictionary attack
- 10. PROBLEM DEFINITION Alpha-numeric passwords have various disadvantages and to overcome this disadvantages GRAPHICAL PASSWORD AUTHENTICATION model has been proposed.
- 11. User Authentication : Graphical Password Use graphics (images) instead of alphanumerical passwords Why? A picture is worth a thousand words Humans remember pictures better than words More resistant to brute-force attacks (search space is practically infinite).
- 12. REGISTRATION TASK USER TASK: U S E R N A M E NEW USER REGISTER DATABASE Click on NEW USER REGISTER button Enter the username in the username field Verifies the username and store into the database
- 13. REGISTRATION TASK PASSWORD CREATION Browse the image Selected image DATABA SE
- 14. LOGIN PHASE PASSWORD VERIFICATION Registered image will generated image Verify in DATAB ASE
- 15. Example MOM LI
- 16. Two Approaches Recognition based Recall based A user is presented with the set of images and the user passes the authentication by recognizing and identifying the images he selected during registration stage. A user is asked to reproduce something that user has created or selected earlier during registration phase
- 17. FLOWCHART Start Upload one image as per choice Select POI(point of interest),POI is described as circle with center and radius A word or phrase can be associated with thePOI Selecting POI Enforce order Donot enforce order Stop
- 18. Advantages Easy to remember and hard to guess for others. Here the security of the system is very high. Provide a way of making more human-friendly passwords . Dictionary attacks are infeasible.
- 19. Existing system In existing system, passwords are mostly of text oriented. Larger memory space. Some are prone to shoulder surfing attack.
- 20. Proposed system In proposed system, author uses a multi-factor graphical password system. During password creation, there is a image associated with text
- 21. IMPLEMENTATION MODEL START Upload one image as per choice Select POI(point of interest),POI is described as square with center and radius Enforce order STOP
- 22. REGISTRATION TASK USER TASK: U S E R N A M E NEW USER REGISTER DATABASE Click on NEW USER REGISTER button Enter the username in the username field Verifies the username and store into the database
- 23. REGISTRATION TASK PASSWORD CREATION Browse the image Selected image DATABA SE
- 24. LOGIN PHASE PASSWORD VERIFICATION Registered image will generated image Verify in DATAB ASE
- 25. Conclusion Search space (system parameters): -picture -POIs (number and order) -words associated with POIs Together, the above parameters define a very large password space (infinite) Multi-factor authentication (graphical, text, POI-order, POI-number)in a friendly intuitive system
