Method for securing a transaction from a non-secure terminal

A terminal comprising a non-transitory machine-readable medium having instructions stored thereon, and at least one processor, the instructions, when executed by the at least one processor result in the terminal:

• executing an impenetrable program configuring the terminal to display, on a display screen of the terminal, an image including a plurality of selectable areas, each selectable area including a respective label, the plurality of selectable areas being distributed in the image in accordance with a first random data, the image including frames that are individually unintelligible to a user, the frames being successively displayed on the display screen at a rate corresponding with persistence of a vision system of the user, such that the respective labels are intelligible to the user;
• collecting positions on the display screen, in relation to the image, designated by the user of using an interface of the terminal;
• and
• transmitting, to a secure processor, the positions on the display screen designated by the user, the user being authenticated by the secure processor if the positions designated by the user correspond to authentication data of the user, known to the secure processor.

A server to comprising a non-transitory machine-readable medium having instructions stored thereon, and at least one processor, the instructions, when executed by the at least one processor cause the server to:

• receive, from a terminal, an authentication request from a user of the terminal;
• generate an impenetrable program executable by the terminal, the impenetrable program, when executed by the terminal, configuring the terminal to display, on a display screen of the terminal, an image including a plurality of selectable areas, each selectable area including a respective label, the plurality of selectable areas being distributed in the image in accordance with first random data, the image including frames that are individually unintelligible to the user, the frames being successively displayed on the display screen at a rate corresponding with persistence of a vision system of the user, such that the respective labels are intelligible to the user;
• transmit, to the terminal, the impenetrable program;
• receive, from the terminal, positions on the display screen designated by the user in relation to the image;
• and
• authenticate the user if the positions designated by the user correspond to authentication data of the user.

A non-transitory computer-readable medium having instructions stored thereon, the instructions, when executed by one or more processors, cause the one or more processors to:

• execute an impenetrable program configuring a terminal to display, on a display screen of the terminal, an image including a plurality of selectable areas, each selectable area including a respective label, the plurality of selectable areas being distributed in the image in accordance with a first random data, the image including frames that are individually unintelligible to a user, the frames being successively displayed on the display screen at a rate corresponding with persistence of a vision system of the user, such that the respective labels are intelligible to the user;
• collect positions on the display screen, in relation to the image, designated by the user using an interface of the terminal;
• and
• transmit to a secure processor the positions on the display screen designated by the user, the user being authenticated by the secure processor if the positions designated by the user correspond to authentication data of the user, known to the secure processor.
