摘要： A system and method for selectively securing data from unauthorized access on a client device storing a plurality of data types with reference to an authorization level indicated in a command. A command is received at a client device comprising an authorization level indicator. Based on at least one predefined rule, which may be implemented in an IT policy stored at the client device, each of the plurality of data types to be secured is determined, and then the data corresponding to those types is secured. The data may be secured by encrypting and/or deleting the data at the client device. The predefined rules associated with each authorization level may be configured by a user or administrator having an authorization level that exceeds the associated authorization level.

摘要： A wireless device (WD) is associated with a preprogrammed user roaming setting and an automated adjustment algorithm stored in operative communication with the device. The algorithm is initiated and run when the device enters a roaming area, thereby automatically activating the roaming setting. A user response query is operatively connected to the automated adjustment algorithm, and operates as a switch for the automated adjustment algorithm, which initiates changing the user settings in accordance with the roaming setting. A user available query is connected to the user response query, to determine if the wireless device is in use, and to generate a notification if the device is idle or a prompt if the device is in use. An output from the switch of the user response query selectively enables the automated adjustment algorithm responsive to at least one of a responsive and a nonresponsive input to the user response query.

摘要： A device certificate binds an identity of a first device to a public key of the first device. The first device comprises a certificate authority service that creates for a process on the first device a process certificate certifying one or more capabilities of the process on the first device. The process certificate is presented to the second device. Upon validating the process certificate using the device certificate, the second device permits the process on the first device to have on the second device one or more of the verified certified capabilities.

摘要： Embodiments of the systems, devices, and methods described herein generally facilitate the secure transmittal of security parameters. In accordance with at least one embodiment, a representation of first data comprising a password is generated at the first computing device as an audio signal. The audio signal is transmitted from the first computing device to the second computing device. The password is determined from the audio signal at the second computing device. A key exchange is performed between the first computing device and the second computing device wherein a key is derived at each of the first and second computing devices. In at least one embodiment, one or more security parameters (e.g. one or more public keys) are exchanged between the first and second computing devices, and techniques for securing the exchange of security parameters or authenticating exchanged security parameters are generally disclosed herein.

摘要： 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.
