Security server for dynamic verification of web content, end users remote device, system comprising said end users remote device and server, and method implemented by said system

A method executed in a system comprising a security server and an end-user remote device, the method comprising the following steps:

• web content is visited on the end-user remote device using an adapted web browser;
• during the web content on the end-user remote device, the adapted web browser sets up a connection with the security server,
• during this setup, the security server triggers the generation of a heartbeat signal between the security server and the adapted web browser;
• on the end-user remote device, interactions with the web content are memorized by the adapted browser and are sent to the security server,
• the security server accesses the web content and replays the interactions on the web content;
• on a variable time interval, a sample of user output is taken on the security server;
• this sample is checked with artificial intelligence of the security server against some pre-defined models and/or patterns memorized during a data mining process on a database:
• if no similar objects or patterns are found in the sample, the security server stops generation of the heartbeat signal, and the adapted browser stops displaying the content, wherein the decision to stop displaying the content is made by the adapted browser, using the detection of lack of the heartbeat signal,
• if an object or pattern similar to the pre-defined models and/or patterns memorized on the database has been found in the sample, the heartbeat signal continues.
