This project focuses on enhancing security through pattern authentication and encryption for Deaf users. It proposes visual patterns for authentication, tackling the shortcomings of text-based passwords and ensuring data encryption remains secure. The low-level design includes steps for file encryption while the RSA encryption source code will be utilized. The project plan entails implementing the proposed solution to provide a secure user experience for Deaf individuals.

Pattern authentication • Visual for Deaf users instead of text • Deaf people are accustomed to signed language • Easy to remember visuals than text [1]
Disadvantages of pattern password • Smudge attack [2] • Over shoulder surfing[3]
Better solution for Encryption • Files should stay Encrypted • Only encrypt the file’s content in memory
Low level Design • Read the input from the file • Generate a random key • Ensure that the key is of the correct bits • Encrypt the input data into cipher text • Return cipher text
