  • Method and system for providing tokenless secure login by visual cryptography
    Patent number: 9984225
    Abstract: A method and system for providing tokenless secure login by visual cryptography. The method includes generating a password sequence and converting the password sequence to a password image. The method also includes encrypting the password image into a first image cipher and a second image cipher. The method further includes transmitting the first image cipher to a first electronic device of a user. Further, the method includes displaying the second image cipher on a second electronic device of the user. Moreover, the method includes enabling decryption of the password image by matching the first image cipher and the second image cipher using an image capture device on the first electronic device. The system includes a plurality of electronic devices, communication interface, memory, and processor.
