    Abstract: A novel code signing system, computer readable media, and method are provided. The code signing method includes receiving a code signing request from a requestor in order to gain access to one or more specific application programming interfaces (APIs). A digital signature is provided to the requestor. The digital signature indicates authorization by a code signing authority for code of the requestor to access the one or more specific APIs. In one example, the digital signature is provided by the code signing authority or a delegate thereof. In another example, the code signing request may include one or more of the following: code, an application, a hash of an application, an abridged version of the application, a transformed version of an application, a command, a command argument, and a library.

    Abstract: A system includes a first wireless-enabled device that transparently stores confidential information and a second wireless-enabled device that stores the same confidential information. The confidential information is to be used to secure a wireless communication link between the first device and the second device. One or both of the first device and the second device is to delete the confidential information upon fulfillment of one or more conditions related to the communication link. The conditions include general timeout, device inactivity, loss of connection over the communication link, a decline in signal strength, and a predefined number of transactions having occurred between the first device and the second device.

    Abstract translation: 系统包括透明地存储机密信息的第一无线功能设备和存储相同机密信息的第二无线功能设备。 机密信息将用于保护第一设备和第二设备之间的无线通信链路。 第一装置和第二装置中的一个或两个是在履行与通信链路相关的一个或多个条件时删除机密信息。 条件包括通常超时，设备不活动，通信链路上的连接丢失，信号强度的下降以及在第一设备和第二设备之间发生的预定数量的事务。

    Abstract: Data is secured on a device in communication with a remote location using a password and content protection key. The device stores data encrypted using a content protection key, which itself may be stored in encrypted form using the password and a key encryption key. The remote location receives a public key from the device. The remote location uses the public key and a stored private key to generate a further public key. The further public key is sent to the device. The device uses the further public key to generate a key encryption key, which is then used to decrypt the encrypted content protection key. A new content encryption key may then be created.

    Abstract translation: 使用密码和内容保护密钥将数据保护在与远程位置通信的设备上。 设备存储使用内容保护密钥加密的数据，该内容保护密钥本身可以使用密码和密钥加密密钥以加密形式存储。 远程位置从设备接收公钥。 远程位置使用公钥和存储的私钥来生成另外的公钥。 进一步的公钥被发送到设备。 该设备使用另外的公钥来生成密钥加密密钥，然后将其用于解密加密的内容保护密钥。 然后可以创建新的内容加密密钥。

    Abstract: A method and system are provided for operating a mobile device, the method comprising: reading a barcode being displayed by another mobile device, to identify a group, by capturing at least one image of the barcode; and joining the group identified by the barcode. Another method and system are provided, the method comprising: storing a barcode on the mobile device, the barcode identifying a group; and displaying the barcode on a display of the mobile device such that the entire barcode is visible on the display to enable another mobile device to scan the barcode to join the group. Another method and system are provided, the method comprising: reading a barcode being displayed by another mobile device, to identify an individual associated with the other mobile device, by capturing at least one image of the barcode; and inviting the individual identified by the barcode to join a group.
