Patent number: 10375089Abstract: A system and method for tracking data security threats within an organization is proposed. A threat aggregator process executing on an analysis computer system within the organization receives events indicating possible threats observed by and sent from different user devices and aggregates related events into threats. This enables the threats to be analyzed and acted upon at a level of the organization (e.g., across user devices) rather than at the level of the individual user devices. An endpoint telemetry system analyzes threats sent from the aggregator and provides security policies for responding to the threats. In examples, the system can identify attacks of related threats and act upon the related threats of the attack collectively, and can characterize false positive threats sent from multiple user devices as a single extraneous threat. This has advantages over the per-user device focus for responding to threats provided by current systems and methods.Type: GrantFiled: March 13, 2017Date of Patent: August 6, 2019Assignee: Carbon Black, Inc.Inventors: Jeffrey Albin Kraemer, Ranganathan Gopalan

The watermark may be applied by phase-space encoding data to be included in the watermark. The image may be examined on a block-by-block basis after scanning. Correlation of detected watermark strength with block brightness and/or with wave vectors used for encoding may be used to detect that the image is a copy.Type: GrantFiled: November 24, 2003Date of Patent: August 9, 2011Assignee: Pitney Bowes Inc.Inventors: Robert A.

Patent number: 7929698Abstract: Certain embodiments consistent with the present invention involve a method of selectively encrypting digital video content that involves receiving a plurality of packets containing the digital video content; identifying packets containing start of frame (SOF) headers; inserting padding into the packets containing SOF headers to move the content of the packets containing the SOF headers to a previous or subsequent packet and create padded packets containing the SOF headers; selecting certain of the packets for encryption according to a selection criterion, wherein the selected packets exclude the padded packets containing SOF headers; encrypting the selected packets; and retaining the padded packets containing the SOF headers unencrypted to form selectively encrypted digital video content. Corresponding decoding method as well as encoding and decoding apparatus are also taught. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.Type: GrantFiled: June 15, 2007Date of Patent: April 19, 2011Assignees: Sony Corporation, Sony Electronics Inc.Inventor: Brant L.

Publication number: 20100272257Abstract: Techniques are described herein for securing communications in a television transmission network. A television receiver receives encrypted content from a transmission network and the encrypted content is input into a decryption device. The decryption device decrypts the encrypted content and generates supplemental data in order to pad the size of the decrypted content. The padded content may then be output from the decryption device to other components of the television receiver, for further processing, such as decoding and output to an associated presentation device.Type: ApplicationFiled: April 27, 2009Publication date: October 28, 2010Applicant: EchoStar Technologies L.L.C.Inventor: William Michael Beals

Patent number: 7802101Abstract: A system and method of retrieving a watermark in a watermarked signal are disclosed. The watermarked signal comprises odd and even overlapped blocks where the watermark is contained in the even blocks. The method comprises, for each k-th even block, subtracting the two adjacent odd numbered blocks from the k-th even block of the watermarked signal to retrieve s *k(n), transforming s *k(n) into the frequency domain to generate S k(f), calculating a phase of S k(f) as ? (f) and a phase of Sk(f) as ?(f), calculating the difference ? (f) between ? (f) and ?(f), unwrapping ? (f) to obtain the phase modulation {tilde over (?)} k(f), and using a Viterbi search to retrieve the watermark embedded in {tilde over (?)} k(f).Type: GrantFiled: March 30, 2009Date of Patent: September 21, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: James David Johnston, Shyh-Shiaw Kuo, Schuyler Reynier Quackenbush, William Turin

Patent number: 7792294Abstract: In certain embodiments, a selective encryption encoder has a packet identifier that identifies packets of a specified packet type. The specified packet type includes packets carrying data representing a video slice wherein the video slice contains a larger amount of data than a threshold amount of data. A packet duplicator duplicates the identified packets to produce first and second sets of the identified packets. Packets are sent and received to and from a primary encryption encoder to encrypt the first set of identified packets under a first encryption method. A secondary encrypter encrypts the second set of identified packets under a second encryption method. This abstract should not be considered limiting since embodiments consistent with the present invention may involve more, different or fewer elements.Type: GrantFiled: February 20, 2007Date of Patent: September 7, 2010Assignees: Sony Corporation, Sony Corporation, Inc.Inventors: Brant L.

Patent number: 7697686Abstract: Example embodiments are directed to a digital audio/video (AV) data processing unit and a method of controlling access to the digital AV data. The processing unit of AV digital data includes a deciphering unit of the AV data, a decompression unit, an input/output interface of the processed AV data and communication device towards a security module. The deciphering and decompression units respectively include an encryption unit and a decryption unit, each having at least one personal key and a common encryption key. Deciphering the AV data using the control words and re-encrypting the deciphered AV data occurs only after a successful verification of the control word and the common key. After temporary storage, the re-encrypted AV data cannot be decrypted by the decryption unit unless the common key has been positively verified by the security module by way of a random number generated by the decryption unit.Type: GrantFiled: November 22, 2005Date of Patent: April 13, 2010Assignee: Nagravision S.A.Inventors: Jean-Michel Puiatti, André Nicoulin, Nicolas Fischer, Guy Moreillon, Fabien Gremaud, Michael John Hill
