摘要： The invention relates to a method for authenticating (400) a current user of a mobile, portable communication system (100) with respect to a server (150) by means of a behavior-based authentication.
The server (150) comprising a first interface and a second interface. The first interface is configured to communicate with at least one activatable device (152), and the second interface is configured to communicate with a mobile, portable communication system (100).
The method for authentication comprises: receiving at least one classification result (600) by the server (150) from the mobile, portable communication system (100); evaluating the at least one classification result (600) by the server according to a predefined examination criterion (800); and activating the device (152) by the server (150) by means of a control signal.

摘要： The invention relates to a method for storing data, wherein the method, in order to store a file (101), comprises: —automatic generation (602) of a distribution schedule (416); —performance (604) of an error correction method, which is specified in the distribution schedule, for generating file fragments from the file by a user computer system; —sending (606) of an authorisation enquiry (420) for storing the file fragments in the memory services (SD2, SD4-SD6) identified in the distribution schedule from the user computer system to a file management server via a network; —in response to reception of the authorisation enquiry by the file management server, requesting (608, 424) of an authorisation token by the file management server from each of the memory services identified in the distribution schedule and forwarding (610) of the authorisation token (428) obtained in response to the request to the user computer system by the file management server; and —storage (612) of the generated file fragments in the storage media (SM2, SM4-SM6) 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 (312) 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.

摘要： The invention relates to a method for cryptographically secure storing a file (101) using a web application executed by a web browser (106) on a user computer system (104, 162, 168) of a user (102, 160). The method comprises:

encrypting the file (101) on the user computer system (104, 162, 168) by the web application,
providing a distribution plan by the web application,
fragmenting the encrypted file (101) on the user computer system (104, 162, 168) by the web application into a plurality of file fragments (F1-F4) according to the distribution plan,
sending the resulting file fragments (F1-F4) by the web application over the network (178) to the storage services identified by the distribution plan (SD1-SD6).

摘要： 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.
