Patent number: 10361865Abstract: In one embodiment, a method, system, and apparatus are described, the method, system, and apparatus including generating metadata to be associated with each block of a series of blocks, the generating including, except for an initial block, receiving: a first block, including a signed block, and a second block to be signed, retrieving a first value including a square of a random number, R?2, multiplying R?2 by a nonce, r, and setting r·R?2 to be a square of a first random number, denoted R2, for the second block, retrieving a second value from the first block, the second value including K-bit vector, E?, determining a bit string value of the second block, M, computing E=hash(R2?M?E?), and determining a signature, Sig, for the second block by calculating Sig=r Sig? SE-E?. Related methods, systems, and apparatuses are also described.Type: GrantFiled: August 29, 2017Date of Patent: July 23, 2019Assignee: Cisco Technology, Inc.Inventors: Eliphaz Hibshoosh, Aviad Kipnis, Nir Moshe, Alon Shaltiel, Yair Fodor

Patent number: 9484037Abstract: Device, system, and method of liveness detection using voice biometrics. For example, a method comprises: generating a first matching score based on a comparison between: (a) a voice-print from a first text-dependent audio sample received at an enrollment stage, and (b) a second text-dependent audio sample received at an authentication stage; generating a second matching score based on a text-independent audio sample; and generating a liveness score by taking into account at least the first matching score and the second matching score.Type: GrantFiled: October 27, 2014Date of Patent: November 1, 2016Assignee: Nuance Communications, Inc.Inventors: Almog Aley-Raz, Nir Moshe Krause, Michael Itzhak Salmon, Ran Yehoshua Gazit

Patent number: 9317667Abstract: A computer program obfuscating system including a processor to provide a computer program including at least one computer program variable, and add an opaque predicate to the computer program to obfuscate the computer program so that the opaque predicate added to the computer program comprises at least one polynomial including a polynomial P, during execution of the obfuscated computer program, the polynomial P is evaluated yielding at least one result including a first result R1, and during execution of the obfuscated computer program, the opaque predicate is evaluated based on the at least one result R1 such that a decision as to whether or not to perform the first command is dependent upon comparing the first result R1 to at least one value in accordance with a predetermined mathematical relationship. Related apparatus and methods are also included.Type: GrantFiled: July 18, 2013Date of Patent: April 19, 2016Assignee: CISCO TECHNOLOGY, INC.Inventors: Harel Cain, Guy Adini, Nir Moshe

Patent number: 9258425Abstract: In many scenarios, speaker verification systems can be given a single-channel audio with recordings of multiple speakers. To perform accurate speaker verification, a system can isolate the speech of a speaker. In one embodiment, a method, and corresponding system, of speaker verification includes extracting a target speaker's speech, using a known speaker voiceprint, from an audio recording that includes the target speaker's speech and the known speaker's speech. The known speaker voiceprint can correspond to the known speaker. Extracting the target speaker's speech can include determining portions of the audio recording where the known speaker voiceprint matches the known speaker's speech above a particular threshold, and extracting the target speaker's speech from other portions of the audio recording. In this manner, speaker verification is performed on the target speaker's speech without interference from the known speaker's speech and allows for a more accurate verification.Type: GrantFiled: May 22, 2013Date of Patent: February 9, 2016Assignee: Nuance Communications, Inc.Inventor: Nir Moshe Krause
