Patent number: 10304010Abstract: A method includes receiving one or more n-gram vectors for a file as input to a file classifier, where the one or more n-gram vectors indicate occurrences of groups of entropy indicators in a sequence of entropy indicators representing the file. The method also includes generating, based on the one or more n-gram vectors, output including classification data associated with the file, the classification data indicating whether the file includes malware.Type: GrantFiled: May 31, 2017Date of Patent: May 28, 2019Assignee: SparkCognition, Inc.Inventor: Na Sai

Patent number: 10068187Abstract: A method includes accessing information identifying multiple files and identifying classification data for the multiple files, where the classification data indicates, for a particular file of the multiple files, whether the particular file includes malware. The method also includes generating n-gram vectors for the multiple files by, for each file, generating an n-gram vector indicating occurrences of character pairs in printable characters representing the file. The method further includes generating and storing a file classifier using the n-gram vectors and the classification data as supervised training data.Type: GrantFiled: May 31, 2017Date of Patent: September 4, 2018Assignee: SPARKCOGNITION, INC.Inventor: Na Sai

Patent number: 10062038Abstract: A method includes accessing information identifying multiple files and identifying classification data for the multiple files, where the classification data indicates, for a particular file of the multiple files, whether the particular file includes malware. The method also includes generating a sequence of entropy indicators for each of the multiple files, each entropy indicator of the sequence of entropy indicators for the particular file corresponding to a chunk of the particular file. The method further includes generating n-gram vectors for the multiple files, where the n-gram vector for the particular file indicates occurrences of groups of entropy indicators in the sequence of entropy indicators for the particular file. The method also includes generating and storing a file classifier using the n-gram vectors and the classification data as supervised training data.Type: GrantFiled: May 31, 2017Date of Patent: August 28, 2018Assignee: SPARKCOGNITION, INC.Inventor: Na Sai

Patent number: 9864956Abstract: A method includes training a file classifier from one or more n-gram feature vectors received from a plurality of binary files as input, where the one or more n-gram vectors represent the occurrences of character pairs in printable characters within the file or characters representing the informational entropy sequence of the file. Another method also includes generating, by the file classifier, output including classification data associated with the file based on the one or more n-gram vectors, where the classification data indicates whether the file includes malware.Type: GrantFiled: May 1, 2017Date of Patent: January 9, 2018Assignee: SPARKCOGNITION, INC.Inventor: Na Sai

Patent number: 8022454Abstract: Ferroelectric structures and methods of making the structures are presented. The ferroelectric structures can include an electrode in contact with a ferroelectric thin film. The contact can be arranged so that a portion of the atoms of the ferroelectric thin film are in contact with at least a portion of the atoms of the electrode. The electrode can be made of metal, a metal alloy, or a semiconducting material. A second electrode can be used and placed in contact with the ferroelectric thin film. Methods of making and using the ferroelectric structures are also presented.Type: GrantFiled: June 16, 2010Date of Patent: September 20, 2011Assignee: The Trustees Of The University Of PennsylvaniaInventors: Andrew Marshall Rappe, Na Sai, Alexie Michelle Kolpak
