A computer-implemented method and system are provided for authenticating the identity of a user registered with a computer system. The authentication method comprises generating a multi-dimensional array of elements that are addressable by respective sets of indices, generating a challenge code comprising a linear array of elements for addressing a first set of indices of the array of elements, transmitting the multi-dimensional array of elements and challenge code to at least one computing device associated with the user, receiving a response code from the user, and verifying the user's identity when the received response code matches a derived code obtained by retrieving elements from the multi-dimensional array at locations addressed by elements taken from the challenge code and a personal code stored at the computer system, wherein the personal code comprises a linear array of elements for addressing a different set of indices of the array of elements. |
