Method and system for authenticating users based on behavior

Abstract

The invention relates to a method based on the behavior of a current user (1) authenticated against a mobile portable communication system (100) having at least one sensor (110) for obtaining macromotion measurement data (500), a macromotion classification module (200) ), processor (130) and internal memory (120). The sensor (110) is designed to obtain gross motor measurement data (500) of gross motor movements of a current user (1) of the mobile portable communication system (100). The gross motor classification module (200) is configured to classify the gross motor measurement data (500) and is trained to recognize gross motor movements of a registered user. The method for behavior-based authentication (400) of a current user (1) with respect to a mobile portable communication system (100) has the following method steps: - Repeated execution of the steps of obtaining large motion measurement data (500), large motion measurement data (500 ) input in the large motion classification module (200), produce the first classification result (600), preserve this first classification result (600)-access the memory (120) of mobile portable communication system (100), so that from memory (120) read at least one stored first classification result (600), - read and analyze at least one first classification result (600) according to predetermined check criteria (800), - generate a verification signal if the check criteria (800) are met (710).

Description

technical field [0001] The present invention relates to a method and system for behavior-based authentication of a user against a mobile portable communication system. Background technique [0002] Mobile portable communication systems are closely integrated into human's daily work and are indispensable. In order to gain access to such systems, a user typically must be authenticated by a personal identification number (PIN), password or perhaps fingerprint. Given the many PIN-protected devices and applications a user uses throughout the day and the many PINs to remember associated with it, it is easy for a user to forget a PIN. Usually freely selectable passwords are either too short to be easy to remember, but this has the disadvantage that they can be guessed quickly and thus provide only low security. In contrast, passwords that provide a high level of security are often long and complex, making them difficult for users to remember. A disadvantage of the fingerprint se...

Problems solved by technology

Given the many PIN-protected devices and applications users use throughout the day and the many PINs to remember associated with it, it is easy for users to forget their PINs

Usually free-chosen passwords are either too short to be easy to remember, but this has the disadvantage that they can be guessed quickly and therefore provide only low security

In contrast, passwords that provide a high level of security are often long and complex, making them difficult for users to remember

The disadvantage of the fingerprint sensor is that the user must additionally place a predetermined finger on it

If he is holding the mobile portable communication system in the wrong hand, the fingerprint sensor can often no longer recognize the user

There are also many situations where the fingerprint sensor does not work correctly, like for example if the user's fingers are dirty or wet, not to mention when the user is wearing gloves
