    • The present disclosure describes a method and apparatus for determining a safety level of a requested uniform resource locator (URL) on a mobile device. Secure memory may be configured to host at least one database comprising a plurality of uniform resource locators (URLs) and to also host information representing at least one logo indicative of a safety level of the URLs in the database. Secure circuitry may be configured to compare a requested URL with the database to determine if the requested URL corresponds to one of the URLs of the database and to select an appropriate logo stored in the secure memory. The secure circuitry may be further configured to direct overlay circuitry to blend the appropriate logo onto rendered data from a frame buffer video memory for display to a user.
    • 本公开描述了一种用于确定移动设备上所请求的统一资源定位符(URL)的安全级别的方法和装置。 安全存储器可以被配置为托管包括多个统一资源定位符(URL)的至少一个数据库,并且还托管代表指示数据库中的URL的安全级别的至少一个标志的信息。 可以将安全电路配置为将所请求的URL与数据库进行比较,以确定所请求的URL是否对应于数据库的一个URL,并选择存储在安全存储器中的适当标识。 安全电路可以被进一步配置成引导覆盖电路将适当的标志混合到来自帧缓冲器视频存储器的渲染数据上,以供用户显示。

    • The present disclosure describes a method and apparatus for collaborative threat detection on mobile devices. A mobile device may comprise a processor, secure memory, and secure circuitry. The processor may be coupled to host memory and may be configured to execute a security threat detection application to detect a malicious program attacking the mobile device. The secure memory may be configured to host a collaborator database comprising data corresponding to at least one collaborating device. The secure circuitry may be configured to determine if the security threat detection application running on the processor is properly operating. If an abnormality in the operation of the security threat detection application is detected, the secure circuitry may be further configured to cause a security threat notification to be transmitted to the collaborating device based on the data in the collaborator database.
    • 本公开描述了用于在移动设备上进行协同威胁检测的方法和装置。 移动设备可以包括处理器,安全存储器和安全电路。 处理器可以耦合到主机存储器,并且可以被配置为执行安全威胁检测应用以检测​​攻击移动设备的恶意程序。 安全存储器可以被配置为托管包括与至少一个协作设备相对应的数据的协作者数据库。 安全电路可以被配置为确定在处理器上运行的安全威胁检测应用程序是否正确地操作。 如果检测到安全威胁检测应用的操作异常,则安全电路可以进一步被配置为基于协作者数据库中的数据使安全威胁通知被发送到协作设备。
