Patent number: 11195171Abstract: A method includes receiving, by a server, a data transmission of video content destined for a data storage device. The method includes generating, by the server, a content signature by application of a wavelet transform to a plurality of frames of a time sequence of frames of the video content. The method includes selecting, by the server based on content metadata for the video content, particular prohibited content signatures from a plurality of prohibited content signatures. Each prohibited content signature of the particular prohibited content signatures corresponds to a wavelet transform of a plurality of frames of prohibited content. The method also includes, in response to a first determination that a first prohibited content signature of the particular prohibited content signatures matches the content signature, preventing transmission of the video content from the server to the data storage device.Type: GrantFiled: May 2, 2018Date of Patent: December 7, 2021Assignee: AT&T Intellectual Property I, L.P.Inventors: Zhi Li, Canhui Ou, Raghvendra Savoor, Dipak Ghosal
