Abstract: 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.

Abstract: 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.

Abstract: A method comprising generating an auxiliary key based on a secret key which is stored in an electronic device, generating a representation of the auxiliary key, displaying the representation of the auxiliary key on a display of the first electronic device, capturing the representation of the auxiliary key with a camera of a second electronic device, and restoring the auxiliary key from the captured representation of the auxiliary key.

Abstract: It is described an apparatus for determining trends in picture taking activity. The apparatus comprises a meta information accessing unit for accessing a set of meta information, each meta information in the set of meta information being associated with a picture having been taken with a camera device at a respective geographic location and at a respective time. The apparatus further comprises a processing unit for determining trends in picture taking activity based on the set of meta information accessible by the meta information accessing unit.

Abstract: A method comprising partitioning a space of user requests into subsets, and determining a risk score for a user request based on the evolution of the number of user requests in the subset of user requests to which this user request belongs.
