Patent number: 11948042Abstract: A system and method for communicating at least one of updated configuration information and hardware setup recommendations to a user of an ID decoding vision system is provided. An image of an object containing one or more IDs is acquired with a mobile device. The ID associated with the object is decoded to derive information. Physical dimensions of the ID associated with the object are determined. Based on the information and the dimensions, configuration data can be transmitted to a remote server that automatically determines setup information for the vision system based upon the configuration data. The remote server thereby transmits at least one of (a) updated configuration information to the vision system and (b) hardware setup recommendations to a user of the vision system based upon the configuration data.Type: GrantFiled: November 15, 2021Date of Patent: April 2, 2024Assignee: Cognex CorporationInventors: Carl W. Gerst, III, James A. Negro, Shane Michael LaChappelle, Vladimir Zivkovic

Patent number: 11809532Abstract: A method for detection of modification of an item of content, the method comprising: obtaining, for the item of content, a respective first value of each attribute in a set of one or more attributes of the item of content, the set of one or more attributes selected such that, for each of one or more predetermined types of modification, said type of modification affects the value of at least one attribute in the set of one or more attributes; performing a watermark decoding operation on the item of content; and in response to the watermark decoding operation producing payload data from the item of content: determining that the one or more predetermined types of modification have not been applied to the item of content if, for each attribute in the set of one or more attributes, the respective first value for that attribute matches a respective second value for that attribute determined using the payload; or determining that a modification has been applied to the item of content if, for at least one attribute iType: GrantFiled: October 14, 2020Date of Patent: November 7, 2023Assignee: Irdeto B.V.Inventors: Arnoud Van Foreest, Kimon Tsitsikas, Vyacheslav Shoshin, Chunqiu Lu, Lin Yuan, Yu Duan, Maksym Koshel, Kostiantyn Shevchenko, Svetislav Momcilovic, Vladimir Zivkovic

Publication number: 20190356966Abstract: Watermarking of a content stream is accomplished in a session-based manner to provide watermarking based on a uniquely generated manifest that will result in a stream that allows for unique identification of information. The manifest specifies a sequence of watermarks for successive segments of a content stream designated for a specific receiver. The system and method leverages existing content distribution infrastructure and has many of the benefits of conventional head-end watermarking, allows unique identification of small segments of the data stream and reduces content distribution network storage requirements. Groups of nodes can be provided with unique watermark patterns and detection and watermark pattern reconfiguration can be accomplished in an iterative manner to find a specific node without the need to create unique watermark patterns for each node.Type: ApplicationFiled: August 1, 2019Publication date: November 21, 2019Applicant: IRDETO B.V.Inventors: Lau Zuydervelt, Vladimir Zivkovic, Maksym Koshel, Lucas Catranis, Yu Duan, Chunqiu Lu, Lin Yuan, Kimon Tsitsikas, Vyacheslav Shoshin

Patent number: 10237065Abstract: There is described a chip for performing cryptographic operations. The chip comprises a key storage module, a rule storage module, an interface module and a cryptographic module. The key storage module is configured to store one or more cryptographic keys. The rule storage module is configured to store one or more rules, each rule comprising respective rule data, the rule data identifying a respective predetermined cryptographic operation associated with the rule and further identifying at least one of the one or more cryptographic keys to be used in the respective predetermined cryptographic operation. The interface module is configured to receive a rule execution request, wherein the rule execution request comprises a rule identifier to identify a specific rule of the one or more rules to be executed. The cryptographic module is configured to execute the specific rule so as to perform the respective predetermined cryptographic operation in response to the rule execution request.Type: GrantFiled: March 31, 2014Date of Patent: March 19, 2019Assignee: Irdeto B.V.Inventors: Hans Dekker, Vladimir Zivkovic
