    摘要: 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.

    摘要: 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.

    摘要: Technologies to facilitate supervision of an online identify include a gateway server to facilitate and monitor access to an online service by a user of a "child" client computer device. The gateway server may include an identity manager to receive a request for access to the online service from the client computing device, retrieve access information to the online service, and facilitate access to the online service for the client computing device using the access information. The access information is kept confidential from the user. The gateway server may also include an activity monitor module to control activity between the client computing device and the online service based on the set of policy rules of a policy database. The gateway server may transmit notifications of such activity to a "parental" client computing device for review and/or approval, which also may be used to update the policy database.
