Patent number: 11877213Abstract: Techniques for obfuscating and deploying digital assets (e.g., mobile applications) are provided to mitigate the risk of unauthorized disclosure. An asset can be received that is to be deployed to a plurality of mobile devices, each of the mobile devices associated with a corresponding account having account attributes. A deployment group of one or more mobile devices for deploying the asset can be identified based on a set of one or more obfuscation parameters, comprising account attributes shared among the one or more mobile devices within the deployment group. A customized obfuscation scheme to be applied to the asset can be determined based at least in part on the set of obfuscation parameters. The customized obfuscation scheme can be applied to the asset to generate an obfuscated asset. The obfuscated asset can be transmitted and/or updated over a network to the one or more mobile devices within the deployment group.Type: GrantFiled: December 17, 2021Date of Patent: January 16, 2024Assignee: Visa International Service AssociationInventors: James Gordon, Roopesh Joshi, David Horton, Johan Van Tilburg

Patent number: 10536263Abstract: An encrypted table value homomorphically joining method and apparatus comprising receiving a query input. Based on the query input, the method may include determining at least one field on which to join the plurality of tables, and determining that the at least one field contains deterministically homomorphically encrypted data. The method may include determining a homomorphic join strategy directly comparing values in two homomorphically encrypted fields, performing a homomorphic join on the fields in the plurality of tables, and providing resultant homomorphically joined tables.Type: GrantFiled: October 9, 2018Date of Patent: January 14, 2020Assignee: Visa International Service AssociationInventors: Paul Payton, Scott Edington, Johan Van Tilburg

Patent number: 6080064Abstract: A pointing device (1), such as a joystick, is provided comprising an integrated Dual Tone Multiple Frequency (DTMF) generator (104) for generating DTMF pointing signals in response to movements of a tiltable stick (12). Preferably, the pointing device (1) also comprises a card reader/writer (106) operatively connected with the DTMF generator (104) by means of a control device (101) for exchanging smart card commands as DTMF signals. A device according to the invention allows games to be remotely played, a smart card (2) being used to pay for the games and/or to collect prizes via a telephone network.Type: GrantFiled: April 24, 1997Date of Patent: June 27, 2000Assignee: Koninklijke PTT Nederland N.V.Inventors: Rob Pieterse, Mark Albert Pors, Martin Klaas De Lange, Frank Pieter Van Pomeren, Johan Van Tilburg

Patent number: 6042006Abstract: An authentication system having a first device and a second device between which signals may be communicated. The first device includes a first memory for storing a definition signal and the first device generates a first signal to be communicated to the second device. The first device also generates a first alteration signal, and introduces an alteration into a first section of the definition signal stored in the first memory in accordance with the first alteration signal. The second device includes a second memory for storing the definition signal, and generates, in response to a receipt of the first signal, a second signal to be communicated to the first device. The second signal includes a second section of the definition signal stored in the second memory, and the second device also generates a second alteration signal and introduces an alteration into a third section of the definition signal stored in the second memory in accordance with the second alteration signal.Type: GrantFiled: August 20, 1997Date of Patent: March 28, 2000Assignee: Koninklijke PTT Nederland N.V.Inventors: Johan Van Tilburg, Andries Pieter Hekstra

Patent number: 5714741Abstract: The invention provides a device (1) for providing a transparent exchange of commands and data between an IC card (11) and a remote terminal (42) via a communication network (41). The device (1) acoustically couples the IC card (11) with a telephone set (43). In order to speed up the exchange of data and commands, the device (1) preferably utilizes high level commands which represent several low level card commands. However, low level commands may also be transparently passed as a special high level command. The device (1) is inexpensive but allows an efficient use of IC cards for, e.g., payment and identification purposes.Type: GrantFiled: April 26, 1996Date of Patent: February 3, 1998Assignee: Koninklijke PTT Nederland N.V.Inventors: Rob Pieterse, Mark Albert Pors, Martin Klaas De Lange, Johan Van Tilburg

Patent number: 5655021Abstract: The invention relates to a method for checking data sequences, comprising a protection step and a verification step, with a control sequence being formed in the protection step on the basis of an identification sequence, which identification sequence comprises identification values which identify data sequences which are to be protected, and which control sequence comprises control values of which at least some have been formed on the basis of operation values, which operation values have been derived from data of sequences which were identified by the said identification values, and with the data sequences being verified, in the verification step, on the basis of the control values. In accordance with the invention control values are formed, successively, by combining an identification value with an operation value related to a preceding control value. The invention is especially useful for verifying data files.Type: GrantFiled: July 20, 1995Date of Patent: August 5, 1997Assignee: Koninklijke PTT Nederland N.V.Inventor: Johan Van Tilburg
