摘要:
The presenting invention relates to techniques for implementing a secure operating environment for the execution of applications on a computing devices (e.g., a mobile phone). In The secure operating environment may provide a trusted environment with dedicated computing resources to manage security and integrity of processing and data for the applications. The applications may be provided with a variety of security services and/or functions to meet different levels of security demanded by an application. The secure operating environment may include a security engine that enumerates and/or determines the security capabilities of the secure operating environment and the computing device, e.g., the hardware, the software, and/or the firmware of the computing device. The security engine may provide security services desired by applications by choosing from the security capabilities that are supported by the secure operating environment and the computing device.

Methods and systems may provide for conducting an authentication of an external card associated with a borrower of a device, and tracking a usage of the device by the borrower if the authentication of the external card is successful. In addition, the usage may be reported to a billing service. The usage may be billed according to a fee based policy so that payment for the usage may be obtained from the borrower of the device rather than the owner of the device.

Generally, this disclosure describes providing theft deterrence for a device while in transit. The system may include lock state circuitry configured to receive and store an unlock token, the unlock token configured to indicate that an associated device has successfully completed transit from a source to a destination; and lock state read circuitry configured to request the unlock token from the lock state circuitry and to determine whether the associated device has successfully completed transit from the source to the destination based on the unlock token.

A mobile phone is disclosed. The mobile phone may receive a first request to generate an initial scannable image, and a second request to generate modified scannable image. The modified scannable image can include a static portion that corresponds to a static portion of the initial scannable image. The modified scannable image may also include another portion that has a different appearance than a corresponding portion of the initial scannable image.

Before a device enters a power saving mode, a location-aware application in the device may provide at least one wake trigger (and a trigger limit) to a low power monitoring module (LPMM). In power saving mode, the LPMM receives device locations from a location service module and may determine when the device location corresponds to the at least one wake trigger or trigger limit. In one embodiment, device location may only be provided to the LPMM based on a condition (e.g., timer expiration or reaching a displacement threshold as measured by sensors in the device). When device location corresponds to the trigger limit, the LPMM may notify the device (e.g., cause a transition to an active power mode) so that the location-aware application can redetermine the at least one wake trigger. The device location corresponding to the at least wake trigger may also cause the LPMM to notify the device.

A method according to one embodiment includes the operations of determining a requested playback media content rating; selecting a pattern matching database associated with the requested playback media content rating; scanning one or more frames of media content; and comparing the scanned frames of media content to the pattern matching database to determine matched frames for omission from playback based on the requested playback media content rating.

Systems and methods may use proximate communication to retrieve information pertaining to a target device. In one example, the method may include detecting the target device within a vicinity of a user device, receiving an information request response communication including information pertaining to the target device, and receiving an operation request response communication including information pertaining to a perforated operation.

Techniques from the proposed invention relate to providing enhanced security. For example, techniques described herein allow a computer system, such as a mobile device, to support a wide variety of security functions and security sensitive applications on a mobile device by providing enhanced security via secure input and output data transmission and verification through a secure module. The secure module may cause user interfaces to be provided to users by providing obfuscated user interface data to the operating system that do not reveal elements that are part of the user interfaces. The secure module may receive obfuscated user input values representing user input values, and de-obfuscate these user input values, whereby the actual input values are not exposed to the underlying operating system. The secure module may track the flow of user input/output data through the computing device to ensure the integrity and authenticity of this data.

Techniques are described for generating high quality entropy in a software only or a hardware assisted software environment, such as a virtualized environment. Embodiments of the invention describe creating an entropy pool within the virtualized environment using multiple sources of entropy. The entropy pool may be used in creating dynamically customizable and high entropy RNG and PUF. The sources of entropy may include trusted sources, untrusted sources and entropy sources with a varied scale of trust and entropy quality associated with them.

In some embodiments, the invention involves parental or master control of a child or subordinate mobile phone without service provider intervention. An embodiment of the invention is a system and method relating to master control of the subordinate smart phone using features on the smart phones, and independent of features provided by the phone service providers. Communication between the master and subordinate phones may be initiated using near field communication, Bluetooth, direct connect to a PC, or by other secure, local wireless or wired connections. Once initiated, desired communication events are captured by the parental control application to effect control policies on the subordinate phone. Communication between the phones may be encrypted to prevent malicious intervention of message traffic. Other embodiments are described and claimed.
