A query-set is used to obtain recommendation results from different recommendation algorithms available locally on a device. The same query-set is used to obtain recommendation results from a remote, well-established online recommendation system using an unknown recommendation algorithm. Distances are measured between the recommendation results from the online recommendation system and the recommendation results from each of the local recommendation algorithms. The local recommendation algorithm having generated recommendation results with a smallest distance to the recommendation results from the online recommendation system is selected for generation of recommendations based on a local recommendation algorithm.

An apparatus and method for securely accessing a web service by a web application running in a browser on a user device is disclosed. A user device sends a request for accessing a web service by addressing a generic name. In response, the user device receives a global name that uniquely identifies a local device hosting a web service. The global name is further associated with a certificate. The user device receives the global name and verifies the certificate associated with the global name to securely access the web service.

A device and a method for authorizing access to a service on a first device upon detection of a second device located in near proximity, while preferably using broadcast transmission, is disclosed. The second device broadcasts on a second broadcast network a message comprising at least a group identifier common to the set of devices that can access the service and a time reference value corresponding to the emission time of the message, according to a common time reference received by all devices from a first broadcast network. The first device authorizes access to the service only if the group identifier received from the message is the same as the group identifier of the device and if the delay between the measured arrival of the message and its emission time is lower than a threshold.

A replication set of k storage devices is defined, that stores a particular data item. Each device in the replication set has an associated timer for which a timeout value for disconnection is determined based on individual downtime data distribution of the device. A new device for storing the data item is added to the replication set when the timer expires for a device in the replication set, and if the number of devices in the replication set that are still connected is below a predetermined threshold. Timeout values are adapted according to a factor of criticalness determined for the replication set, resulting in a more reactive, or on the contrary, a less reactive replacement of devices in the replication set. The factor of criticalness is determined according to a difference between the connected devices in the replication set and the predetermined number k.
