A transaction method for a user using a first and a second terminal and connected to a server via a first and a second communication channel, respectively. The first terminal sends a transaction amount to the server. The server establishes a verification code whose length depends on the transaction amount, then sends a request to the first terminal and the verification code to the second terminal. The user returns the request filled in with a copied code to the server using the first terminal. The server compares the verification code with the copied code and sends a transaction validation or invalidation message to the first terminal depending on the comparison.

Transaction authentication method, server and system using two communication channels

A method for determining an association between a bankcard identifier and at least one mobile communications terminal identifier. The method is implemented by an electronic device and includes: obtaining an identifier of a current bankcard, a bankcard used to make a purchase of an article or a service by using a payment terminal, the obtaining being implemented at the time of the execution of a payment transaction made by using the bankcard; at least one step of obtaining a piece of data representative of at least one communications terminal identifier; and computing a score of correspondence between bankcard identifier and the at least one piece of data representative of a communications terminal identifier.

Method for determining an association between a bankcard and a communications terminal, device, system and corresponding program

A method of encryption of a message implemented by an electronic encryption device. The method includes: obtaining a current message; obtaining a current encryption key; determining, from a plurality of variants a basic encryption protocol, of a current variant of the encryption protocol; encrypting, by using the current variant and the encryption key, the message to be encrypted, delivering an encrypted message; and transmitting the encrypted key.

Method of encryption, method of decryption, corresponding computer device and program

A method for processing data by an electronic data-acquisition device, requesting to obtain data from an electronic data-providing device. The electronic data-acquisition device and the electronic data-providing device communicate with each other by using a short-range wireless (NFC) communications technology defining a transmission/reception reference frequency. The method includes the following acts performed by the electronic data-acquisition device: determining a frequency of transmission/reception of an interrogation signal that is different from the transmission/reception reference frequency, as a function of a frequency-determining parameter, delivering an interrogation frequency; and after determining the interrogation frequency, transmitting the interrogation signal to the data-providing device at the interrogation frequency.

Method for processing data by means of an electronic data-acquisition device, corresponding device and program

A method for processing display data is implemented by an electronic data processing device. The display data represents at least one piece of information to be displayed on a screen. The method includes: for obtaining at least one reference image representing the at least one piece of information to be displayed; and generating at least one altered image from the reference image and from at least one alteration parameter.

The disclosure relates to a method for transmitting data and to a corresponding method for receiving data. According to the disclosure, in the method for transmitting data, a cryptographic processing operation is performed on the data to be transmitted, after this data has been pre-subdivided into blocks of data, and a tag representing each block of encrypted data is computed. The tag is then transmitted in such a way that a hacker in not able to reproduce a correct transmission of tags. The method of reception, for its part, ensures that when an incorrect tag is received (because of a hacking attempt), the processing of the data blocks is not immediately stopped but a differential processing is implemented in order to jam an attempt to analyze the behavior of the receiver.
