The present disclosure relates to a method for sharing data with at least one user, wherein the data is legally owned by a data owner and to be published by a data publisher. The method comprises deriving, by the data owner, a publisher key based on an owner key held by the data owner and providing the publisher key to the data publisher. Further, the method includes deriving, by the data publisher, a symmetric access key based on the publisher key and at least one attribute of a subset of the data and encrypting the subset with the symmetric access key. The method further comprises deriving, by the data owner, the symmetric access key based on the owner key and the attribute, and providing the symmetric access key to the user to enable the user to decrypt using the symmetric access key the subset encrypted by the data publisher.

Concept for sharing data

A method for sharing encrypted data including encrypting first data with at least one first attribute. The first attribute satisfies a first access policy of a first cryptographic key to enable one or more first users holding the first cryptographic key to decrypt the encrypted first data using the first cryptographic key. The method includes encrypting second data with at least one second attribute of the second data. The method includes generating a second cryptographic key based on a second access policy including at least one logical connective of the first attribute and the second attribute for decrypting the encrypted first data and the encrypted second data using the second cryptographic key and providing the second cryptographic key to one or more second users to enable the second users to decrypt the encrypted first data and the encrypted second data.

Method, computer program, and data processing circuitry for access control to encrypted data using attributes of the data

A method and a head-mounted device for triggering an action with relation to a selected object in a field of view of a user comprising detecting a pre-defined brain activity pattern of the user using a brain activity sensor of a head-mounted device worn by the user. The pre-defined brain activity pattern expresses a user command to select an object on which a gaze of the user is focused. The method comprises determining a direction of the gaze of the user at a time of the detection of the pre-defined brain activity pattern. The method comprises capturing an image of the field of view of the user at the time of the detection of the pre-defined brain activity pattern. The method comprises providing at least a part of the image to a computing entity, to cause the computing entity to trigger the action with relation to the selected object.

Method, computer program and head-mounted device for triggering an action, method and computer program for a computing device and computing device

The present disclosure relates to a distance measurement system The system comprises a transmitter device and a receiver device. The transmitter device and the receiver device are clock-synchronized to each other. The transmitter device is configured to emit an ultrasonic signal at one or more predefined transmit times known to the transmitter and the receiver device. The receiver device is configured to receive the ultrasonic signal and to estimate a distance between the transmitter device and the receiver device based on the received ultra-sonic signal and the one or more predefined transmit times.

Methods and apparatuses for distance measurement

A device for authenticating a user is described that comprises a sensor configured to measure the movement of a user in response to the interaction of the user with a displayed image and controller circuitry configured to authenticate the user in response to a positive comparison between the movement of the user and a stored movement associated with the user.

Device, computer program and method

The present disclosure generally relates to authenticating a user of a mobile device based on motion data of said mobile device. Embodiments provide a method, apparatus and computer program for authenticating a user, a mobile device comprising such an apparatus and a system. The method comprises detecting an outfit of the user. The method comprises analyzing a gait of the user using a machine-learning model using motion data of a mobile device as input to the machine-learning model. The analysis is based on the identified outfit of the user. The method comprises authenticating the user based on the analysis of the gait of the user.

Concept for authenticating a user of a mobile device

In an authentication method, a wireless communication is established between a mobile device and a wearable device. A proximity is detected between the mobile device and the wearable device by comparing mobile device position information and wearable device position information. Access to the mobile device is granted based on a detected proximity.

Authentication method, wearable device and mobile device

A device for authenticating a user is described. This device comprises transceiver circuitry configured to receive motion information from a plurality of wearable devices located on a user's body indicative of the motion of the user's body at the location of the respective wearable device at a particular time; and 5 controller circuitry configured to: compare the received motion information and the location of the respective wearable device and authenticate the user in the event of a positive comparison between the received motion information and the location of the respective wearable device with stored motion information and the location of the respective wearable device.

An apparatus has circuitry which determines a location of a user, based on sound data representing speech of the user, and identifies the user based on the determined location of the user and user identification information and location information received from a mobile device.

Apparatus and method to identify a user based on sound data and location information

The present disclosure relates to a concept of proximity detection. A sequence of keystrokes is captured when a person types on a keyboard placed on a support structure. A sequence of vibrations of the support structure in response to typing on the keyboard is captured with a sensor device associated with a user or a location and in contact with the support structure in proximity to the keyboard. The proximity between the person and the sensor device is checked based on a comparison of the captured sequence of keystrokes with the captured sequence of vibrations.

Methods and apparatuses for proximity detection

A method for authenticating a user of an electronic device is provided. The method includes displaying a section of a graphical representation to the user on a display of the electronic device. The graphical representation comprises a graphical object. Further, the method includes requesting the user to navigate to the graphical object. Additionally, the method includes capturing data from one or more sensors of the electronic device that is indicative of a movement of the electronic device by the user for navigating to the graphical object and/or data from one or more input devices of the electronic device that is indicative of a user input by the user for navigating to the graphical object. The method further includes authenticating the user based on the captured data.

Methods for authenticating a user of an electronic device

The present disclosure relates to an electronic device which comprises a circuitry configured to authenticate a second electronic device when the circuitry detects based on a privacy preserving algorithm that the two electronic devices are associated with the same body. Furthermore, the present disclosure relates to a method comprising authenticating data communication between a first electronic device and a second electronic device when detecting based on a privacy preserving algorithm that the two electronic devices are associated with the same body.
