Abstract: A method for collecting transaction history data and an associated terminal device. The method may include: collecting on-line, from a remote server (SV), first history data (DT) representative of at least one transaction associated with a user account (15); communicating contactlessly with a smart card (2), during which the terminal (T) recovers second history data (DH) stored locally in a memory (10) of the smart card, the second history data being representative of transactions processed by the smart card in association with the user account (15); and analyzing, during which the terminal (T) aggregates the first and second history data in order to obtain up-to-date history data. It is thus possible to generate transaction-following data from the up-to-date history data.

Abstract: A method for assisting in improving the security of an electronic operation carried out via a secure element. The method comprises the following steps. A first application of the secure element is selected and writes a piece of contextual data in means of recording of the secure element. Then, a second application is selected, reads the contextual data in the means for recording and verifies if the contextual data satisfies a predefined condition. If yes, it is considered that the context of the selecting of the second application is legitimate and the electronic operation can continue normally.

Abstract: A security method performed by an electronic device (CD) and the electronic device. The method includes determining a current time point during which a current transaction is carried out; selecting, from a log file (LG) in which at least one past transaction is stored, each transaction carried out by the electronic device (CD) during a predefined time period terminating at the current time point; analyzing risk from log data stored in the log file in association with each selected transaction in order to detect whether an abnormal use of the electronic device (CD) has occurred during the predefined time period; and if so, triggering at least one security operation for the electronic device (CD) in response to the current transaction.

Abstract: An authentication method is performed between a first party and a second party. The method includes: i) determining a challenge; ii) sending the challenge to the second party; receiving a response from the second party including a second cryptogram; computing a first cryptogram using the challenge and the key of the first party; determining if the first cryptogram matches the second cryptogram received from the second party. If the first cryptogram does not match the second cryptogram, the method further includes performing a computation using the first cryptogram and the second cryptogram; and comparing a result of the computation with a stored set of results to recover a first data element carried by the second cryptogram.
