Abstract: A processing technique can be implemented by a security device. The security device verifies that a message sent by a communicating device to a receiving device is a message to be sent. When the verification is positive, the message is sent to the receiving device. The security device than receives a notification sent by the receiving device indicating that the sent message is to be blocked. Subsequent messages of the same type as the message for which the notification was received, sent by communicating devices provided by the same manufacturer and with the same product identifier as those of the communicating device that sent the message are thus blocked by the security device during the verification process.

Abstract: A technique for connecting a user device to a service. The device sends a request to connect to the service, a user identifier of the device from a trusted entity being associated with the request. The trusted entity sends a reply to the request back to the device. This reply includes data about a uniform resource locator associated with the service and a single-use code and is sent to a contact address associated with the user identifier from the trusted entity. The device then sends a request to access a page of the service, the address of which corresponds to the data, the received single-use code being associated with the access request. Connection to the service is authorized for the service identifier associated with the user identifier from the trusted entity, when a single-use code received from a server implementing the service, in combination with a service identifier request, is valid.

Abstract: A method and apparatus for inputting at least one character by way of a user interface of an electronic device. The method includes: detecting a scrolling command performed by way of a command input element; displaying a current character in a display area by scrolling through a current set of characters, triggered by the detection of the scrolling command; detecting a selection of the current character; determining a new restricted set of characters on the basis of the current set of characters, the new set including the selected character and a selection of characters surrounding the selected character and becoming the current set of characters for a following iteration of the display of the scrolling of characters; and detecting a confirmation of the current character by way of the command input element, putting an end to the iterations.
