摘要： In RFID systems employed for loss prevention, an item supplier or an ingress reader writes an ownership code associated with an organization or facility into a tag, indicating that an item to which the tag is attached is associated with the facility and not foreign. At checkout or point-of-sale an authorization reader writes a digital signature into the tag indicating that the tagged item is allowed to leave the facility. At point-of-exit an exit reader determines if the tagged item is allowed to leave the facility by verifying the ownership code and the digital signature. The loss-prevention system may issue an alert or sound an alarm if a facility-associated item is leaving the facility without a proper digital signature indicating that the item is approved to leave.
摘要翻译：在用于损失预防的RFID系统中，物品供应商或入口读取器将与组织或设施相关联的所有权代码写入标签，指示标签所附着的物品与设施而不是外部相关联。在结帐或销售点，授权读者将数字签名写入标签，指示允许标记的物品离开设施。在退出点处，退出阅读器通过验证所有权代码和数字签名来确定标记的物品是否被允许离开设施。如果与设施有关的物品离开设施而没有正确的数字签名，表明物品被批准离开，则防损系统可能会发出警报或发出警报。

摘要： An authentication method includes RFID readers authenticating RFID tags using public-key cryptography. A tag manufacturer or other legitimate authority produces a tag private-public key pair and stores the tag private key in externally unreadable tag memory and the tag public key in externally readable tag memory. The authority produces a master private-public key pair and distributes the master public key to readers in the field. The authority generates a tag-specific electronic signature based on at least the tag public key and the master private key and stores this signature in externally readable tag memory. A reader authenticates the tag by retrieving the tag public key and electronic signature from the tag, verifying the authenticity of the tag public key using the master public key and the electronic signature, challenging the tag, receiving a response from the tag to the challenge, and verifying the response using the tag public key.

摘要： Radio frequency identification (RFID) tags selected for inventorying using combination of preselect and/or post select criteria. The selection commands can be for selecting according to a tag memory content, by invoking the mask address or by comparing other tag characteristics. Selection criteria can be determined locally at a modem block of a reader or provided to the modem block by higher layers of the reader. Tags meeting the selection criteria are reported to the higher layers for further actions. Some tags may be held while waiting for instructions from the higher layer block(s).
摘要翻译：使用预选和/或后选择标准的组合选择进行库存的射频识别（RFID）标签。选择命令可以根据标签存储器内容，通过调用掩码地址或通过比较其他标签特征来进行选择。选择标准可以在读取器的调制解调器块本地确定，或者由阅读器的较高层提供给调制解调器块。满足选择标准的标签被报告给较高层以进行进一步的操作。在等待来自较高层块的指令的同时可以保持一些标签。

摘要： RFID readers, systems, and methods are provided for overcoming the effects of RF interference. While a system is communicating in a channel, RF interference is monitored. If it is low, then hopping to another channel is performed according to an ordinary decision. But if interference is high, then hopping out to another channel can be earlier than would be dictated by the ordinary decision under the same circumstances. The earlier hopping out can result in diminishing communication in channels with a lot of RF interference.

摘要： RFID readers transmit a Quiet Technology (QT) command to RFID tags causing at least one of the tags to transition between a private profile and a public profile. When a tag is inventoried in the private profile, it replies to the reader with contents from its private memory. When a tag is inventoried in the public profile, it replies to the reader with contents from its public memory, where the contents of the public memory may be a subset and/or modified version of the private memory contents, or entirely different altogether. The tag's profile can be switched again by another QT command from the reader, or following a loss of power at the tag. An access password and/or a short-range mechanism may be employed to allow only authorized readers to transition tag profiles or interrogate the private memory contents of tags in the public profile.
摘要翻译： RFID读取器将安静技术（QT）命令传输到RFID标签，使至少一个标签在私有配置文件和公共配置文件之间转换。当标签在专用配置文件中进行盘点时，它会从其专用内存中的内容中回复读卡器。当在公共简档中标记标签时，它从其公共存储器中的内容回复读取器，其中公共存储器的内容可以是专用存储器内容的子集和/或修改版本，或者完全不同。标签的配置文件可以通过读写器的另一个QT命令重新切换，或者在标签丢失电源之后。可以采用访问密码和/或短程机制来仅允许授权的读者转换标签简档或询问公共简档中的标签的私人存储器内容。

摘要： A Radio Frequency Identification (RFID) reader containing a reader key authenticates an RFID tag containing a tag key by receiving a reader challenge from a verification authority; determining a reader response based at least on the reader challenge and the reader key; sending a first message including at least the reader response but not the reader key to the verification authority; receiving a tag identifier from the tag; challenging the tag with a tag challenge; receiving a tag response based at least on the tag challenge and the tag key but not including the tag key; sending a second message including at least the tag identifier and the tag response to the verification authority; and receiving an electronically-signed reply from the verification authority. The reader validates the verification authority reply by checking the signature. The verification authority may notify a designated party if a response is incorrect.

摘要： RFID tags, ICs for RFID tags, and methods are provided. In some embodiments, an RFID tag includes a memory with multiple sections, and a processing block. The processing block may map one of these sections, or another of these sections, for purposes of responding to a first command from an RFID reader. As such, an RFID tag can operate according to the data stored in the section mapped at the time. In some embodiments, a tag can even transition from mapping one of the sections to mapping another of the sections. This can amount to the tag exhibiting alternative behaviors, and permits hiding data on the tag.
摘要翻译： RFID标签，RFID标签的IC和方法。在一些实施例中，RFID标签包括具有多个部分的存储器和处理块。处理块可以映射这些部分中的一个或这些部分中的另一个，以便响应来自RFID读取器的第一命令。因此，RFID标签可以根据当时映射的部分中存储的数据进行操作。在一些实施例中，标签甚至可以从映射中的一个部分转换为映射另一个部分。这可以代表展示替代行为的标签，并允许在标签上隐藏数据。
