  • Patent number: 9148406
    Abstract: A media stream source protection system in which a media stream is passed through a gatekeeper before being used by any other software or hardware within the information handling system. In certain embodiments, the video camera encrypts and the gatekeeper decrypts content received from the video camera before the content is provided to the gatekeeper. In certain embodiments, the encryption is performed on the camera device as part of the video encode incorporated the video camera thus providing a bandwidth-saving measure.

  • Patent number: 9021164
    Abstract: A NFC mimic device retrieves peripheral information from a peripheral, stores the peripheral information and then mimics the peripheral information to an information handling system so that a NFC device of the information handling system receives the peripheral information as if provided directly from the peripheral. The NFC mimic device supports automated setup a wireless interface between an information handling system and a peripheral, such as a projector.

  • Patent number: 8931074
    Abstract: A hardware secured flag mechanism which is activated by trusted Anti-Malware (AM) software. Upon being activated, the information handling system takes action to reduce user exposure even if the AM software is subsequently subverted. In certain embodiments, the flag mechanism is only reset by user intervention at a BIOS or other off-line mechanism. In certain embodiments, the flag mechanism may only be reset via a signed unlock key stored on an external memory device such as a universal serial bus (USB) key.

  • Patent number: 8896718
    Abstract: A video camera privacy lock is set forth. The video camera privacy lock includes a low level filter driver that install and maintains a first position in a filter graph. The filter driver provides a locked media signal to the next sequential item rather than to a media stream until and unless the filter is unlocked. The locked media signal may be a blank screen, a text message, an icon, a static image (such as an avatar, a photograph, etc., pixilated video, or some other predetermined output). Also, in various embodiments, the driver is locked by default, thereby increasing user trust that the video camera only transmits a media signal when desired.

  • Patent number: 8875210
    Abstract: A system for providing video conference touch blur. More specifically, in certain embodiments, a video conference touch blur operation is performed by actuating (e.g., via touch or via a mouse operation) a video conference screen image to blur areas that are not to be transmitted in high definition.

  • Publication number: 20140292659
    Abstract: A method of determining user input into an information handling system includes determining a region of a zero-volume trackpad overlaying a keyboard area, detecting an access of the zero-volume trackpad, and determining whether to interpret the access as input into the zero-volume trackpad based upon timing of the input.

  • Patent number: 8848028
    Abstract: Stereo audio cues are provided at an information handling system to associate audio with its source based upon the characteristics of the image of the source as presented at a display of the information handling system. For example, in one embodiment, a location on a display of a window having a videoconferencing participant is used to create a stereo audio location that correlates audio associated with the participant to the window location. In another embodiment, the size on a display of a window having a videoconferencing participant is used to determine the volume of audio that is associated with the participant.

  • Patent number: 8782776
    Abstract: A simple, customizable and intuitive virtual combination unlock method and system. More specifically, an unlock system and method is disclosed which includes a virtual combination lock, where the virtual combination lock includes several rows of user-selectable images such as pictures or icons as the virtual combination wheels. In certain embodiments, the images are accessed via the user's database. To unlock the device, the user touches and drags pre-selected images into alignment with each other. Security can be adjusted by changing the number of images that need to be aligned to unlock the device.

  • Patent number: 8682897
    Abstract: A system and method are disclosed for managing playlists of digital content. Digital content preference data is received from a plurality of users. The preference data is then processed to generate a group preference playlist, which contains references to digital content that is mutually preferred by each of the users. The group preference playlist is then initiated to play the mutually-preferred digital content.

  • Patent number: 8325148
    Abstract: A secured communication channel is established between two or more information handling systems by defining attributes for encrypting information with physical inputs made at touch devices of the information handling systems. Inputting the physical gesture at a touch device of each information handling system allows evaluation of one or more attributes at each information handling system so that the shared secret of the physical gesture form the basis for encrypted communications. The touch device includes touch screens or touch pads and the attributes include gesture speed, plural distinct gesture touch points, movement of touch points relative to each other, or other attributes that are determinable from physical gesture inputs at each information handling system.

  • Publication number: 20100100854
    Abstract: A gesture operation input system includes one or more subsystems to receive an input indicating a modifier input, receive a gesture input, wherein the gesture input indicates an action to be performed, and receive an indication that the modifier input is no longer being received. After receiving the gesture input, the gesture operation input system then determines the action to be performed using the gesture input and performs the action.
