Abstract: A portable payment or retail terminal with jack connector and a method for secure identification of a cardholder, the terminal including a set of devices and arrangement for implementing the method, which has at least: detecting the presence of a jack plugged in the connector of the terminal for connecting a cardholder's headset, triggering the execution of an accessibility mode allowing the cardholder to identify, the method being wherein it includes at least: scrambling and maintaining the screen in black during the sequence of the accessibility mode, generating a chain of keys comprising a set of keys for PIN/SNL entry, attributing a value of key corresponding to the length d of the finger's displacement; selecting among pre-registered audio signals corresponding to each key of the chain of keys, the sound corresponding to the key attributed to the displacement and emit it through the jack connector towards the cardholder's headset.

Abstract: A security server for dynamic verification of web content located on a platform in the cloud or in the edge which runs artificial intelligence (AI) algorithms including a collector receiving collection of user interactions from an adapted browser of a remote to simulate content of pages loaded on the device based on user interactions from an adapted browser located on the end-user device navigating on the web and for sampling the outcome of these interactions at irregular time intervals, this sample resulting a fixed image such as JPG or PNG, a data mining and artificial intelligence (AI) algorithm relying on image processing executed while sample interval to detect object or patterns on the displayed content, a heartbeat generator generates heartbeat at regular interval and transmits at a continuous interval to the end-user's device to indicate to the adapted browser of the device it may display the content.
