Embodiment Construction

[0040] In the drawings, the same reference symbols may refer to the same parts in different drawings, unless specified otherwise.

[0041] Hereinafter, the term "secure" is used according to its ordinary meaning to those of ordinary skill in the art, and in various embodiments, it encompasses security resulting from techniques such as encryption, or Other types of software or hardware controls that isolate information from the public or protect information from unauthorized access or manipulation. The expressions "secure communication" and "secure communication link" refer to communications that are encrypted using a public / private key pair, or symmetric key encryption with keys shared between communication points. "Protected communications" may also refer to virtual private networks, and other methods and techniques for establishing authenticated and encrypted communications between communication points.

Abstract

The invention relates to a method for securely transmitting secret information to a user, the method comprising: receiving by the user terminal, from a secure processor, a software component protectedagainst tampering and reverseengineering and configured to generate sets (SG) of adjacent pixels having a probability lower than 100% to be in a visible or invisible state; executing the software component by the user terminal, at a frame display refresh rate, to generate the pixel sets at the display refresh rate; inserting the pixel sets generated by each execution of the software component into one respective image frame (FRM); and activating display of the image frames at the frame display refresh rate, the image frames including information (KYL, CC) which is machine unintelligible as being formed of the pixel sets, the information becoming intelligible to a user at the display refresh rate thanks to the persistence of the human visual system.

Description

technical field [0001] The present invention relates to a method and a device for securely authenticating a user from a non-secure terminal, and for performing a secure transaction involving such a non-secure terminal and a remote server based on such user authentication. Background technique [0002] Desiring to execute from a mobile terminal such as a smartphone, personal computer, digital tablet, or any other connected device (including devices belonging to the Internet of Things (IoT)) (not sure this is relevant because the claimed method A transaction that requires a person) to initiate, such as an e-commerce transaction or a funds transfer. However, this creates security concerns, especially since the terminals processor (CPU) may execute "malware". Malware may be able to access all or part of the memory accessible by the processor, and thus may be maliciously configured to monitor any transactions performed by the terminal and recover any confidential data manipulate...
