    • The invention provides a system and method for content protection. A system according to an embodiment includes a media center connectable to a mobile secure and protection keyring associated with an identifier and with a media Key block MKB. The media center includes: a unique identifier identifying the media center MC_UID, a set of device keys DK; storage means for storing files identified by respective file identifiers; and a processing unit comprising file encryption means for encrypting each file before storage in the storage means, using a title key (Kt) computed from the identifier MC_UID of the media center and for encrypting the title key Kt from the set of device keys DK of the media center, and from the identifier and the media key block MKB of the mobile secure and protection keyring, the media center being further provided to write the encrypted title key (eKt) in association with the file identifier of the file to the mobile secure and protection keyring.
    • 本发明提供了一种用于内容保护的系统和方法。 根据实施例的系统包括可连接到与标识符和媒体密钥块MKB相关联的移动安全和保护密钥环的媒体中心。 媒体中心包括:识别媒体中心MC_UID的唯一标识符,一组设备密钥DK; 用于存储由相应文件标识符标识的文件的存储装置 以及处理单元,其包括文件加密装置,用于使用从媒体中心的标识符MC_UID计算的标题密钥(Kt)来加密存储在存储装置中的每个文件,并且从标识密钥Kt的装置密钥DK 媒体中心,并且从移动安全和保护密钥环的标识符和媒体密钥块MKB,还提供媒体中心以将与文件的文件标识符相关联的加密的标题密钥(eKt)写入到移动安全 和保护钥匙圈。

    • A location localization method and system. The method includes transmitting by an RFID tag reader, a request for locating a passive RFID tag in a facility. The RFID tag reader receives from a first group of active RFID tags, a first date/time associated with first data. The RFID tag reader transmits to the first group of active RFID tags, a request for retrieving the first data. The first data comprises distances between each active RFID tag of the first group and the passive RFID tag. The RFID tag reader receives the first data. The RFID tag reader receives a map of the facility and locations on the map for the first group of active RFID tags. The RFID tag reader determines a location within the facility for the passive RFID tag based on the first data, the map, and the locations on the map. The RFID tag reader transmits the first location to a user.
    • 位置定位方法和系统。 该方法包括通过RFID标签读取器发送在设备中定位无源RFID标签的请求。 RFID标签读取器从第一组有源RFID标签接收与第一数据相关联的第一日期/时间。 RFID标签读取器向第一组有源RFID标签传送检索第一数据的请求。 第一数据包括第一组的每个有源RFID标签与无源RFID标签之间的距离。 RFID标签读取器接收第一数据。 RFID标签读取器接收用于第一组有源RFID标签的设施的地图和地图上的位置。 RFID标签读取器基于第一数据,地图和地图上的位置来确定无线RFID标签在设施内的位置。 RFID标签读取器将第一位置发送给用户。

    • The present invention is directed to a method and apparatus for radio frequency identification (RFID) tag positional addressing. A method in accordance with an embodiment of the present invention includes: activating a plurality of first RFID tags, wherein each first RFID tag emits an identification (ID) and a position; capturing the IDs and positions emitted by the first RFID tags using a plurality of second RFID tags, wherein each second RFID tag captures the IDs and positions emitted by the first RFID tags located in a vicinity of the second RFID tag, and wherein each second RFID tag determines its physical location based on the captured IDs and positions; and sending a read command including a position of a targeted one of the second RFID tags that is to be read, wherein only the targeted second RFID tag located at the position in the read command responds to the read command.
    • 本发明涉及用于射频识别(RFID)标签位置寻址的方法和装置。 根据本发明的实施例的方法包括:激活多个第一RFID标签,其中每个第一RFID标签发射标识(ID)和位置; 使用多个第二RFID标签捕获由第一RFID标签发射的ID和位置,其中每个第二RFID标签捕获位于第二RFID标签附近的由第一RFID标签发射的ID和位置,并且其中每个第二RFID标签 标签根据捕获的ID和位置确定其物理位置; 并且发送包括要读取的第二RFID标签中的目标一个的位置的读取命令,其中只有位于读取命令中的位置的目标第二RFID标签响应于读取命令。
