  • Patent number: 11888847
    Abstract: Systems and methods are provided for context-based authentication, via a decentralized network. One example method includes receiving, at a mobile device, from a relying party, a request for an attribute of a user in connection with an interaction between the user and the relying party and determining a type of authentication to be used for the interaction, based on an authentication policy of the relying party and multiple context signals stored in the mobile device prior to providing the attribute to the relying party. The multiple context signals are indicative of one or more patterns indicative of the user and/or the mobile device. The method also includes soliciting authentication data from the user consistent with the determined type of authentication, receiving, by the mobile device, the solicited authentication from the user, and providing the attribute to the relying party in response to the user being authenticated at the mobile device.

  • Patent number: 11874943
    Abstract: Presented here is a system that manages secured file system, and an authority to the secured file system, by granting access only to a user who is authorized to access the file system. The user within the system is identified using a unique key unique to each user. The user's authority is recorded in a linear sequence distributed among multiple devices each of which independently verifies the validity of each block in the linear sequence. The validity of the linear sequence is guaranteed by preventing certain operations from being performed on the linear sequence, such as branching of the linear sequence, deletion, and modification of the blocks within the linear sequence. Prior to adding a new block to the linear sequence, the validity of the block is independently computed by each of the devices.

  • Patent number: 11870786
    Abstract: The present disclosure involves systems, software, and computer implemented methods for access control for object instances. A method includes receiving, at a cloud application, a user request associated with a user. The user request corresponds to an instance of a first application artifact type. Role assignments for the user are retrieved from a cloud platform and a determination is made that the role assignments grant permission to the first application artifact type to the user. A determination is made that a first instance-based access policy exists for the first application artifact type. A determination is made regarding whether the first instance-based access policy grants permission for the user to access the instance. The user request is serviced in response to determining that the first instance-based access policy grants permission for the user to access the instance.

  • Patent number: 11848942
    Abstract: A method and system for detecting intrusion in a distributed field bus of a vehicle network involve using an Intrusion Detection System (IDS) to detect intrusion in the network. In a network with a number of nodes, IDS is configured in each of the number of nodes. The IDS, in a first node configured in a transmission mode, receives at least one message signal. A hash function is performed on at least one message signal for generating a first Honeypot (HPT) signal. Simultaneously, the first node transmits the first HPT signal to the second node. The first node and the second node generates a reference HPT and second HPT respectively using an echo-hash function. The IDS detect intrusion based on a comparison of the reference HPT and the second HPT. The method is independent of network traffic timing and can be performed in real-time.

  • Patent number: 11848946
    Abstract: Some embodiments of the invention provide a method for performing intrusion detection operations on a host computer. The method receives a data message sent by a machine executing on the host computer. For the data message's flow, the method identifies a set of one or more contextual attributes that are different than layers 2, 3 and 4 header values of the data message. The identified set of contextual attributes are provided to an intrusion detection system (IDS) engine that executes on the host computer to enforce several IDS rules. The IDS engine uses the identified set of contextual attributes to identify a subset of the IDS rules that are applicable to the received data message and that do not include all of the IDS rules enforced by the IDS engine. The IDS engine then examines the subset of IDS rules for the received data message to ascertain whether the data message is associated with a network intrusion activity.

  • Patent number: 11841974
    Abstract: A system may include an interface configured to couple to a network, and includes a processor and a memory accessible to the processor. The memory may be configured to store instructions that, when executed, cause the processor to process search results corresponding to multiple data owners to selectively filter personally identifiable information (PII) associated with one or more consumers from the set of search results according to data sharing permissions for each of the data owners to produce filtered results. The instructions may further cause the processor to provide the filtered results to a user device through the network.

  • Patent number: 11823509
    Abstract: A vehicle processing device authenticates that an authorized user has requested an action by the vehicle and generates an authentication acknowledgement message. At least two security devices being present within the cabin of, or close to, the vehicle during a predetermined period following an authentication trigger event that occurs while the user performs a predetermined sequence of authentication activities (i.e., button presses, operating the vehicle or a part of it, etc.) provides a basis for the authentication acknowledgement message. Typically, information unique to each security device has been associated with the vehicle at a service provider's server. The authentication acknowledgement may include an activation code that results from processing the information, unique to each security device, received from the security devices and other random information, such as date.
