Abstract: Authenticating method for a user of a service uses both a personal computer (PC) and a personal connectable device over a communications network. An enrollment phase must be fulfilled first, for determining a list of properties of the user. Request for a new session is accompanied by the submission of credentials by the user. Then, a type 1 graphic interactive object is evoked in which a grid of colored cells shows on the user PC screen and at least some of the cells of the grid contain images, and at least one was chosen by the user in the enrolment phase. Service continues with an assessment stage unless a type 2 graphic interactive object is employed. A type 2 graphic interactive object only at least one cell in which a color identical to the color appears in the cell on the PC in which a chosen image appeared before.

Abstract: A method for authenticating a user of a service provided over a communications network. The user uses both a personal computer (PC) and a personal connectable device, both connected to a communications network, Before using the service, an enrollment phase must be fulfilled, for determining a list of properties of the user. Upon initiating a session by the user in which a request for a new session accompanied by the submission of credentials by the user, and then evoking a type 1 graphic interactive object in which a grid of colored cells shows on the user PC screen and at least some of the cells of the grid contain images, and at least one of which images was chosen by the user in the enrolment phase, Thereafter the service continues to the assessment stage unless a type 2 graphic interactive object is employed. A type 2 graphic interactive object only at least one cell in which a color identical to the color appearing in the cell on the PC in which a chosen image appeared before.

Abstract: A method and system for ensuring the secure authentication of transactions over a communication network using a validation code 40, wherein the user submits information over a communication terminal and submitting validation code 40 for authentication allows the transaction to be completed, the system comprised of: a substantially transparent alphanumeric cipher card 10 associated with the user information, wherein cipher card 10 contains rows and columns of random alphanumeric characters; and an authentication module for providing validation code 40 to the user whereby a color grid 20 is generated to be displayed on a user terminal, wherein the cells of color grid 20 are randomly filled with one of a plurality of colors and the design of color grid 20 is adapted to cipher card 10 such that upon positioning alphanumeric cipher card 10 over color grid 20, the user can deduce a validation code 40.
