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.

Method and apparatus for accessing and displaying private user information

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.

Method and apparatus for generating privacy ratings for applications

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.

Method and apparatus providing privacy benchmarking for mobile application development

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.

Methods and apparatus for reporting location privacy

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. A method for certificate authorities (CA) that use Bloom filters for certificate revocation list (CRL) compression that enables the CA to hash only the entry that is to be un-revoked so that a good compression rate may be provided while avoiding computation of the entire CRL for each un-revocation.

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.

Method and apparatus for preserving privacy for appointment scheduling

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.
