The invention relates to a method for behaviour-based authentication () of a current user () to a mobile, portable communication system (), which has at least one sensor () for capturing gross-motor measurement data (), a gross-motor classification module (), a processor (), and an internal memory (). Furthermore, a user is registered in the mobile, portable communication system (). The sensor () is designed to recognise the gross-motor measurement data () of a gross-motor movement of the current user () of the mobile, portable communication system () and the gross-motor classification module () is trained to capture a generic gross-motor movement pattern with the help of training data sets of a user cohort. In addition, the gross-motor classification module () implements a machine-learning method. The gross-motor classification module () is executed by the processor () of the mobile, portable communication system ().

Method and system for behavior-based authentication of a user

The invention relates to a method for cryptographically secure storing a file () using a web application executed by a web browser () on a user computer system () of a user (). The method comprises:

Secure storage of and access to files through a web application

The invention relates to a method for authenticating () a current user of a mobile, portable communication system () with respect to a server () by means of a behavior-based authentication. The server () comprising a first interface and a second interface. The first interface is configured to communicate with at least one activatable device (), and the second interface is configured to communicate with a mobile, portable communication system (). The method for authentication comprises:

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

A file management server may include a processor, a network interface for operatively coupling the file management server to a user computer system and to memory services via a network. The file management server includes a file management application configured to receive an authorisation enquiry of the user computer system to store file fragments of a file via the network in a plurality of the memory services; and in response to the receipt of the authorisation enquiry, request an authorisation token from each of the memory services and forward, to the user computer system, authorisation tokens formed as URLs and obtained in response to the request. Each URL enables direct write or direct read access to a storage space of one of the memory services identified by the URL. Metadata that allows reconstruction of the file from the stored file fragments is protected against access by the memory services.

Distributed data storage by means of authorisation token

The method for the behavior-based authentication of the current user to a mobile, portable communication system includes repeated performance of capturing the gross-motor measurement data, inputting the gross-motor measurement data into the gross-motor classification module, generating a first classification result, and storing the first classification result. The method further includes accessing of the memory of the system in order to read out at least one of the stored first classification results from the memory, reading out of the at least one first classification result and evaluating same in accordance with a specified checking criterion, and generating an authentication signal if the checking criterion is met.

The invention relates to a method for storing data, wherein the method, in order to store a file (), comprises: &#x2014;automatic generation () of a distribution schedule (); &#x2014;performance () of an error correction method, which is specified in the distribution schedule, for generating file fragments from the file by a user computer system; &#x2014;sending () of an authorisation enquiry () for storing the file fragments in the memory services (SD, SD-SD) identified in the distribution schedule from the user computer system to a file management server via a network; &#x2014;in response to reception of the authorisation enquiry by the file management server, requesting () of an authorisation token by the file management server from each of the memory services identified in the distribution schedule and forwarding () of the authorisation token () obtained in response to the request to the user computer system by the file management server; and &#x2014;storage () of the generated file fragments in the storage media (SM, SM-SM) of the identified memory services by means of authorisation verification by the authorisation token by means of the user computer system bypassing the file management server; wherein metadata () that permit the reconstruction of the file from the stored file fragments are stored in the user computer system and/or the file management server and are protected against access by the memory services.
