Patent number: 11533623Abstract: Apparatus, methods, and computer-readable media for facilitating detection of false base stations based on signal times of arrival are disclosed herein. An example method for wireless communication of a UE includes receiving a signal from each of one or more neighboring base stations. The example method also includes determining a system timing associated with the wireless communications network based on a respective time of arrival at which each signal is received from the neighboring base stations. The example method also includes receiving a signal from an FBS, the FBS signal being associated with a PCI different than the PCIs associated with the signals received from each of the neighboring base stations. Additionally, the example method includes identifying a presence of the FBS based on a difference between the system timing and a time of arrival at which the signal is received from the FBS.Type: GrantFiled: October 30, 2020Date of Patent: December 20, 2022Assignee: QUALCOMM IncorporatedInventors: Ravi Agarwal, Gavin Bernard Horn, Naga Bhushan

Patent number: 11455003Abstract: A computational device receives an input/output (I/O) operation directed to a data set. In response to determining that there is a time lock on the data set, a determination is made as to whether a clock of the computational device is providing a correct time. In response to determining that the clock of the computational device is not providing the correct time, the I/O operation is restricted from accessing the data set. In response to determining that the clock of the computational device is providing the correct time, a determination is made from one or more time entries of the time lock whether to provide the I/O operation with access to the data set.Type: GrantFiled: November 15, 2019Date of Patent: September 27, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Matthew G.

Example watermark encoding apparatus disclosed herein determine which one of a plurality of timestamp cycles is to be represented by a timestamp of a watermark. Disclosed example apparatus also swap at least two symbols of the watermark when the timestamp is to represent a second one of the timestamp cycles, but do not swap the at least two symbols of the watermark when the timestamp is to represent a first one of the timestamp cycles. Disclosed example apparatus further embed the watermark in a first piece of media.Type: GrantFiled: May 27, 2021Date of Patent: September 20, 2022Assignee: THE NIELSEN COMPANY (US), LLCInventors: Vladimir Kuznetsov, Alexander Topchy

Patent number: 11445373Abstract: For validation of position, navigation, time (PNT) signals, a hash included in messages with PNT data is used to validate the source of the message without backhaul. Different tags from a hash chain are included in different messages. The receiver is pre-loaded with the root or later trusted hash tag of the chain as created. The hash of any received message may be hashed by the receiver. The result of the hashing will match the pre-loaded or trusted hash tag if the transmitter of the message is a valid source. The PNT data may be validated using a digital signature formed from the PNT data for one or more messages and the hash tag wherein a hash tag of the chain in a subsequently received message is used as the key. The digital signature may be formed from data across multiple messages.Type: GrantFiled: August 5, 2019Date of Patent: September 13, 2022Assignee: SATELLES, INC.Inventors: Michael L. O'Connor, David G. Lawrence, Gregory Gutt

Patent number: 11422825Abstract: An SSD includes a controller having a first non-volatile memory in which a power-off timestamp is stored, and a hardware register accessible by a host. The SSD also includes a second non-volatile memory coupled to the controller, the second non-volatile memory storing instructions for at least one boot-up mode of the SSD. Upon power up of the controller and prior to the controller executing the instructions for at least one boot-up mode of the SSD, the controller receives, in the hardware register, a power-on timestamp from the host and determines, based on the power-on timestamp and the stored power-off timestamp, a boot-up mode of the SSD.Type: GrantFiled: December 30, 2020Date of Patent: August 23, 2022Assignee: Kioxia CorporationInventor: Jithendra Devegowda

Patent number: 11409724Abstract: Aspects create a tree data structure that indexes a collection of documents present in a data repository at a point in time. The tree data structure includes a plurality of nodes. For each such node, a respective root hash value of that node is determined. The root hash value of a leaf node is determined from hash value(s) for element(s) of that node that are keyed to documents in the collection. The root hash value of a parent node is determined from a root hash value for each of its child nodes. For a given document that is purported to be a target document present in the data repository at the point in time, processing is performed that uses the tree data structure in facilitating verification that the given document is the target document. This includes providing a cryptographic proof to demonstrate whether the given document is the target document.Type: GrantFiled: March 10, 2020Date of Patent: August 9, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventor: Jeronimo Irazabal
