Method and system for the behavior-based authentication of a user

Abstract

The invention relates to a method for the behavior-based authentication of a current user (1) to a mobile, portable communication system (100). Said communication system has at least one sensor (110)for capturing gross-motor measurement data (500), a gross-motor classification module (200), a processor (130), and an internal memory (120). The sensor (110) is designed to capture gross-motor measurement data (500) of a gross-motor movement of a current user (1) of the mobile, portable communication system (100). The gross-motor classification module (200) is configured for classification of thegross-motor measurement data (500) and trained for recognition of a gross-motor movement of a registered user. The method for the behavior-based authentication (400) of the current user (1) to a mobile, portable communication system (100) has the following steps: repeated performance of the following steps: capturing the gross-motor measurement data (500), inputting the gross-motor measurement data (500) into the gross-motor classification module (200), generating a first classification result (600), storing the first classification result (600), accessing the memory (120) of the mobile, portable communication system (100) in order to read out at least one of the stored first classification results (600) from the memory (120), reading out the at least one first classification result (600)and evaluating same in accordance with a specified checking criterion (800), producing an authentication signal (710) if the checking criterion (800) is met.

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
