Abstract: For accessing and displaying private user information, a privacy-preserving overlay platform determines a request, from at least one application, for user data. The privacy-preserving overlay platform processes and/or facilitates a processing of the data to generate at least one index value of the data. Further, the privacy-preserving overlay platform causes, at least in part, a return of the at least one index value to the at least one application in response to the request.

Abstract: An approach is provided for generating privacy ratings for applications. A privacy ratings platform determines use information associated with one or more applications executing on one or more devices. By way of example, the use information is determined based, at least in part, on usage data associated with one or more input sources, one or more components, one or more categories of personal information, or a combination thereof associated with the one or more devices. The privacy ratings platform then processes and/or facilitates a processing of the use information to determine one or more privacy ratings for the one or more applications.

Abstract: A method operates, during development of an application program intended to be run on a mobile user device, to perform a computer assisted analysis of the application program to determine at least one user privacy-related aspect of the application program; and to present the determined at least one user privacy-related aspect. The determined at least one user privacy-related aspect may be presented to a developer of the application program. An apparatus and system for performing the method are also disclosed.

Abstract: Privacy evaluation in a mobile electronic device. Location data collected by one or more applications operating on the electronic device is evaluated to determine the precision with which a user's location and movements can be reconstructed based on the location data collected by one or more of the applications. Information relating to such precision may be presented to the user, suitably by a graphic display representing a circle or ellipse within which the user's movement cannot be determined or a set of streets within which the user's movement cannot be determined.

Abstract: A method for providing efficient management of certificate revocation may comprise storing a list of identifiers of digital certificates including a revocation list defining a list of revoked certificates in an accumulator, storing a witness value in association with at least some entries in the revocation list in which the witness value provides proof of the membership or non-membership of an identifier in the revocation list, enabling generation of a new accumulator and a new witness value responsive to each insertion or deletion of an entry in the revocation list, and enabling batch updates to the revocation list using a reduced bitlength value generated based on to a ratio of a value generated based on elements added to the revocation list to a value generated based on elements deleted from the revocation list. A corresponding apparatus is also provided.

Abstract: Embodiments of this invention relate to the field of sharing and publishing content. It is inter-alia disclosed to obtain content at a device, to determine whether or not the content is associated with at least one potentially sensitive entity and, in case that it is determined that the content is associated with at least one potentially sensitive entity, non-modally notifying a user of the device that the content is associated with at least one potentially sensitive entity and/or preventing an at least unintentional sharing and/or publishing of the content by a user of the device.

Abstract: Methods and apparatuses are provided for accessing and displaying private user information. A privacy-preserving overlay platform determines a request, from at least one application, for user data. The privacy-preserving overlay platform processes and/or facilitates a processing of the data to generate at least one index value of the data. Further, the privacy-preserving overlay platform causes, at least in part, a return of the at least one index value to the at least one application in response to the request.

Abstract: An approach is provided for preserving privacy for appointment scheduling. A scheduling platform receives a request to schedule an appointment among one or more users. The scheduling platform determines availability information for the one or more users from one or more respective devices, wherein the availability information is encrypted using homomorphic encryption. The scheduling platform then processes and/or facilitates a processing of the availability information using, at least in part, one or more homomorphic functions to determine one or more recommended time slots for the appointment.

Abstract: A method and an apparatus provide for operating a user interface of a device to receive from a user, for individual ones of a plurality of user privacy categories, a user privacy setting; to map each user privacy setting to one or more device sensors to form a sensor policy for the user privacy category; and to monitor application program accesses to device sensors to detect a violation of a sensor policy. An aspect of the exemplary embodiments of this invention is the user interface that can represent privacy levels of each application program to the user in a “user-friendly” format. Another aspect of the exemplary embodiments is to provide the user device with an ability to detect and act on or at least report privacy violations by the application programs.

Abstract: An approach is provided for categorizing user-initiated and application-initiated access to device resources. The monitoring platform determines one or more access requests by at least one application to one or more resources of at least one device. The monitoring platform processes and/or facilitates a processing of the one or more access requests to cause, at least in part, a categorization of the one or more access requests based, at least in part, on whether the one or more access requests were initiated by a user of the at least one device. The monitoring platform causes, at least in part, an assessment of the at least one application based, at least in part, on the categorization.

Abstract: A radio terminal includes a radio interface configured to allow radio communication with a radio base station, and a controller configured to control switching between a wake-up state in which the radio interface is turned on and a sleep state in which the radio interface is turned off. The radio terminal acquires a reference wake-up timing scheduled as a wake-up timing for switching from the sleep state to the wake-up state. The controller shifts the wake-up timing from the reference wake-up timing.

Abstract: Apparatuses, realtime-stations, computer programs, and methods for scheduling of traffic in wireless networks are provided. In one embodiment, a method is provided for scheduling of traffic in a wireless networks including real-time stations intending to send real-time traffic and best-effort stations sending best effort traffic. The method can include overhearing for a predetermined period of time the traffic by a station which intends to send real-time traffic, and if from the overhearing the station concludes that there is already a primary station transmitting real-time access markers, assuming by the station a sequence number based on the number of real-time stations which already are sending real-time traffic.
