Abstract: Technologies for audiovisual communication include an audiovisual server and a number of audiovisual client devices, including a presenter device and a number of audience devices. Each audience device captures an audiovisual stream and transmits the audiovisual stream to the audiovisual server. Each audience device also captures sensor input data such as eye tracking data or facial expression data and transmits abstracted sensor input data to the audiovisual server. The abstracted sensor input data may be based on the captured audiovisual stream. The audiovisual server determines an interestingness rating associated with each audience device based on the sensor input data, and selects one or more audiovisual streams based on the interestingness ratings. The audiovisual server transmits the selected audiovisual streams to the presenter device. The audiovisual server may update the interestingness rating algorithm based on feedback from the presenter device or the audience devices.

Abstract: An item of value comprises an assembly of parts. The parts comprise a component that has value independent of the item, and an assembly security system that is operable to communicate with a central security system via a wide area network. The component comprises a component security system that is operable to communicate with the assembly security system. The assembly security system is operable to perform operations comprising (a) saving component data that identifies the component as part of the item; (b) after saving the component data, monitoring the component, via the component security system, to automatically determine whether the component has left a predetermined zone of proximity, relative to the item; and (c) in response to determining that the component has left the predetermined zone of proximity, automatically notifying the central security system that the component has left the predetermined zone of proximity. Other embodiments are described and claimed.

Abstract: Embodiments of methods, apparatuses, and storage mediums associated with eye movement based knowledge demonstration, having a particular application to authentication, are disclosed. In embodiments, a computing device may determine whether a received input of a pattern of eye movements is consistent with an expected pattern of eye movements of a user when the user attempts to visually locate a piece of information embedded in a display. In embodiments, the expected pattern of eye movements may include patterns related to fixations and/or other statistical patterns, however, may not be limited to such patterns. In applications, determining consistency or correlation with the expected pattern of eye movements may identify the user by simultaneously verifying at least factors of authentication—that of biometric criteria related to a user's pattern of eye movements and a password or other information known to the user.

Abstract: A technique allows detection of covert malware that attempts to hide network traffic. By monitoring network traffic both in a secure trusted environment and in an operating system environment, then comparing the monitor data, attempts to hide network traffic can be detected, allowing the possibility of performing rehabilitative actions on the computer system to locate and remove the malware hiding the network traffic.

Abstract: Methods, apparatus, systems and articles of manufacture detect spoofing attacks for video-based authentication are disclosed. Disclosed example method to perform video-based authentication include determining whether a sequence of input images provided to perform video-based authentication of a subject exhibits a first region having fluctuating pixel values. Such example methods also include determining that the sequence of input images is associated with a spoofing attack in response to determining that the sequence of input images exhibits the first region having fluctuating pixel values.

Abstract: Systems and methods may provide for receiving runtime input from one or more unlock interfaces of a device and selecting a level of access with regard to the device from a plurality of levels of access based on the runtime input. The selected level of access may have an associated security policy, wherein an authentication of the runtime input may be conducted based on the associated security policy. In one example, one or more cryptographic keys are used to place the device in an unlocked state with regard to the selected level of access if the authentication is successful. If the authentication is unsuccessful, on the other hand, the device may be maintained in a locked state with regard to the selected level of access.

Abstract: Technologies for de-duplicating encrypted content include fragmenting a file into blocks on a computing device, encrypting each block, and storing each encrypted block on a content data server with associated keyed hashes and member identifications. The computing device additionally transmits each encrypted block with an associated member encryption key and member identification to a key server. As part of the de-duplication process, the content data server stores only one copy of the encrypted data for a particular associated keyed hash, and the key server similarly associates a single member encryption key with the keyed hash. To retrieve the file, the computing device receives the encrypted blocks with their associated keyed hashes and member identifications from the content data server and receives the corresponding member decryption key from the key server. The computing device decrypts each block using the member decryption keys and combines to blocks to generate the file.

Abstract: An embodiment of the invention allows a user to back-up/store data to a cloud-based storage system and synchronize that data on the user's devices coupled to the storage system. The devices have secure out-of-band cryptoprocessors that conceal a private key. The private key corresponds to a public key that is used to encrypt a session key and information, both of which are passed to and through cloud based storage, all while remaining encrypted. The encrypted material is communicated from the cloud to another of the user's devices where the encrypted material is decrypted within a secure out-of-band cryptoprocessor (using the private key that corresponds to the aforementioned public key) located within the device. The embodiment allows for secure provisioning of the private key to the devices. The private key is only decrypted within the cryptoprocessor so the private key is not “in the open”. Other embodiments are described herein.
