  • Patent number: 9521153
    Abstract: A system and method of providing a platform trust extension for an information handling system is disclosed herein. The platform trust extension receives a notification that an application is selected for installation or execution on an information handling system. The identify of the application or the source of the application is identified based upon a signature of the application. The platform trust extension determines whether the application or the source of the application is semi-trusted based upon the signature of the application. If the application is semi-trusted, the platform trust extension permits the application to run at an additional trust level.

    Abstract: Active content is deterministically rendered in a stable format that is independent of any particular targeted environment, which the active content may subsequently be rendered to. Environmental and dynamic dependencies are removed from a specification associated with the active content for purposes of producing a stable and consistent specification for the active content. The stable and static specification is used to subsequently render the active content into the stable format for any targeted or desired environment.

  • Patent number: 9521000
    Abstract: A service provider manages access control to multiple services through an authentication system. One or more services are able to fulfill requests at least in part by submitting requests to other services of the service provider. Such a service is able to obtain, from the authentication system, information that can be passed on to one or more other services to enable the one or more other services to determine request validity without having to contact the authentication system. The information may include, for example, one or more responses that the one or more other services would have received had the one or more services contacted the authentication system themselves.

  • Patent number: 9514505
    Abstract: A method for detecting a payload embedded using watermarking in a content stream, the payload being different in a first and a second segment of the content stream, a payload in the second segment having a predetermined relationship with a payload in the first segment, is described. The method selects a point in the content stream where the first segment is likely to end and the second segment to being, samples the stream to obtain a first set of samples that is before the chosen point and a second set of samples that is after the chosen point, and detects the payload on a combination of the first set and a transformation of the second set, where the transformation is based on the assumption that the second set is from the second segment and exploits the relationship that exists between the payloads in the first and second segments.

The content distribution method includes a list transmission step S11, a content request step S12, and a content transfer step S13. In S11, a source device transmits metadata which includes a format identifier indicating that content is distributable under the specification of the HDCP and the URL of the content. In S12, a sink device makes a request for content identified by the URL after adding information necessary for authentication processing to the request. In S13, the source device creates an encryption key by performing the authentication processing on the sink device in accordance with the information necessary for the authentication processing, encrypts the content using the encryption key, and transfers the encrypted content to the sink device.

    Abstract: Embodiments of the present invention provide an approach to repair vulnerabilities (e.g., security vulnerabilities) in images (e.g., application images) in a networked computing environment (e.g., a cloud computing environment). Specifically, an image is checked for vulnerabilities using a database of known images and/or vulnerabilities. If a vulnerability is found, a flexible/elastic firewall is established around the image so as to isolate the vulnerability. Once the firewall has been put in place, the vulnerability can be repaired by a variety of means such as upgrading the image, quarantining the image, discarding the image, and/or generating a new image. Once the image has been repaired, the firewall can be removed.

    Abstract: Facilities are provided herein for authenticating a user to use a processing device. A user predefines authenticators of one or more types and associates these with graphical images. Upon on attempt to activate the processing device, a graphical image, of the graphical images, is selected for presentation to the user. The selected graphical image is presented to the user, who then provides input to authenticate with the device. A determination is made as to whether the user is authenticated to use the device. The determination is made based on input received from the user and based further on the authenticator associated with the selected graphical image. Varying the selection of image(s), each associated with a predefined authenticator and authentication type, enables variability in the authenticator that is suitable for unlocking a device at a given time, providing greater security to the authentication process.

  • Patent number: 9461875
    Abstract: The invention dynamically obscures network and transport layer addresses of packets to achieve anonymity, including authentication privacy, as well as protection against tracking and traffic correlation and certain classes of network attacks by combining both intrusion protection with anonymity, avoiding the use of a separate management unit outside the host for distribution of obscured addresses. The invention enables a host to automatically configure obscured addresses and determine the obscured address of the intended recipient without outside involvement, computing addresses based on a set of parameters, and to operate without re-authentication whenever an address changes. The invention enables encryption of the packet payload to prevent traffic correlation. The technology of the invention can be implemented embedded on a host device or as a connected gateway device and requires negligible configuration and is therefore transparent to hosts.

The airtime correlator is configured to correlate airtime usage of the selected communication channel by the WAP with one of an idle WLAN state characterized by an absence of upstream or downstream communications and an active WLAN state characterized by at least one of upstream and downstream communications on the WLAN. The dormancy allocator is configured to allocate during at least one of the idle and the active WLAN states, a portion of available airtime to at least one dormancy interval in which a base power level of the WAP is reduced at least below a level required to support downstream communications. The MAC is configured to identify for the plurality of station nodes on the WLAN, a contention free period overlapping in time with the at least one dormancy interval.

  • Patent number: 9384521
    Abstract: The invention relates to a method for assessing the presence of a watermark in a video wherein the video comprises at least a sequence of frames. The method comprises for at least one frame among one of the sequences of frames the steps of computing a set of axial cross-correlation values, wherein each axial cross-correlation value corresponds to a correlation between the frame and a reference watermark shifted along a spatial horizontal axis; obtaining a detection score by computing a weighted sum of values output by a function applied to said axial cross-correlation values; assessing the presence of a watermark according to the detection score. Such method is particularly well adapted to the detection of disparity coherent watermark but is compliant with any watermarking technique. A device implementing the method is further disclosed.
