    • 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.
    • 一种方法和装置,用于操作设备的用户界面以从用户接收用于多个用户隐私类别中的个别用户隐私类别的用户隐私设置; 将每个用户隐私设置映射到一个或多个设备传感器以形成用于用户隐私类别的传感器策略; 并监视对设备传感器的应用程序访问,以检测违反传感器策略。 本发明的示例性实施例的一个方面是可以以“用户友好”格式向用户表示每个应用程序的隐私级别的用户界面。 示例性实施例的另一方面是向用户设备提供检测应用程序或者至少报告应用程序的隐私违规的能力。

    • 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.
    • 用于提供证书吊销的有效管理的方法可以包括存储数字证书的标识符列表,包括定义撤消证书的列表的撤销列表在累加器中,存储与撤销列表中的至少一些条目相关联的证人值, 证人值提供了撤销列表中的标识符的成员身份证明或非成员身份证明,能够响应于撤销列表中的条目的每次插入或删除而生成新的累加器和新的证人值,并且允许批量更新 所述撤销列表使用基于基于添加到撤销列表的元素生成的值与基于从撤销列表中删除的元素生成的值而生成的缩减比特长度值。 还提供了相应的装置。 一种使用布隆过滤器进行证书吊销列表(CRL)压缩的证书颁发机构(CA)的方法,该方法使CA只能对未撤销的条目进行散列,以便可以提供良好的压缩率,同时避免计算 每个撤销的整个CRL。
