Abstract: 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 said 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 said data-providing device at the interrogation frequency.

Abstract: 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.

Abstract: 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.
