Abstract: An authentication platform for authenticating an online user is provided. The authentication platform includes a memory device including an authentication profile and at least one processor coupled to the memory device. The at least one processor is programmed to receive an authentication request message for a transaction. The authentication request message includes authentication data. The at least one processor is also programmed to extract the authentication data from the authentication request message and determine if the ACS is available to process the transaction. If the ACS is unavailable, the at least one processor is further programmed to generate, based at least in part on the extracted authentication data, risk-based authentication (RBA) result data including a risk score and transmit an authentication response message based on the RBA result data.

Abstract: Systems and methods are provided for associating confirmed user (CU) indications to network-initiated transactions. An example method includes receiving network details for a transaction between a user and a first party and storing the network details in a data repository in association with an transaction identifier for the transaction. The method also includes accessing, from the data repository, network details for multiple prior transactions between the user and the first party and comparing the network details for said transaction and the network details for the multiple prior transactions. The method then includes, based on a match between the network details for said transaction and the network details for the multiple prior transactions, appending a confirmed user flag in an authorization message for the transaction, whereby an issuer relies on the confirmed user flag in deciding to approve or decline the transaction.

Abstract: The disclosure herein describes a system for measuring probability of influence in digital communications to determine if communication content originated in a person's own prior knowledge or new information more recently obtained from interaction with communications of others. An estimated probability a new communication by a first user comes from the same distribution as prior communications of the first user are generated using multidimensional statistics on embeddings representing the communications. A second estimated probability that the new communication comes from the same distribution as communication(s) of a second user that were accessible to the first user are generated. If the second probability is greater than the first probability, the new communication is more likely influenced by exposure of the first user to the second user's communications rather than the first user's own historical knowledge.

Abstract: Apparatus, methods, and computer-readable media for facilitating autonomous synchronization are disclosed herein. For example, a UE may be configured to perform an initial synchronization directly to PSCCH and PSSCH when other synchronization sources, such as GNSS, a base station, and/or SLSS, are unavailable. An example method for wireless communication at a user equipment includes receiving a PSCCH. The example method also includes performing an initial synchronization based on the PSCCH. In some examples, the method may also include receiving a PSSCH, and determining a logical subframe number modulo 10 based on the PSSCH. The logical subframe number modulo 10 may correspond to a sequence seed.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adjust a basic safety message generation periodicity based at least in part on a semi-persistent scheduling periodicity for transmitting basic safety messages. The UE may generate one or more basic safety messages based at least in part on the adjusted basic safety message generation periodicity. Numerous other aspects are provided.

Abstract: Systems and methods are provided for managing digital identities associated with users. One exemplary method includes receiving, at a computing device, an encrypted message from a communication device associated with a user where the message includes a changed attribute for the user. The method also includes generating a first hash of a first digital identity for the user with the changed attribute and generating a second hash of a second digital identity of the user stored in a ledger data structure. And, in response to the first hash not matching the second hash, the method then includes broadcasting a pending status of the first digital identity to a relying party for the second digital identity, and storing a certification of the changed attribute, received from the relying party in response to the pending status, based on verification of the changed attribute by the relying party.

Abstract: The embodiment herein provides a system and method for providing a novel leader election mechanism in distributed systems that is randomized in twin dimensions of space and time using the concept of a colliding random walk (CRW). Leader election is randomized in space in terms of the node identified as the leader and the time taken to identify the leader. A source node is enabled to generate left and right coupons in a quantum resistant manner for random walks. A novel fault tolerance mechanism is provided to identify several leaders for same set of coupons. In this system and method, the source vertex generates multiple CRWs for each piece of work that needs to be done. The fault tolerance mechanism reduces the time to collision, increases the number of leaders and also offers increased resilience and tolerance to faults.

Abstract: Aspects directed towards synchronizing out of coverage (OOC) vehicle-to-everything (V2X) communications are disclosed. In one example, a scheduled entity detects a loss of a synchronization signal associated with a V2X communication by detecting when a timing uncertainty value or error value is greater than a threshold value. Packet timing information is then received in response to the loss of the synchronization signal from at least one user equipment (UE) synchronized with the synchronization signal. The scheduled entity then maintains the V2X communication by performing a timing adjustment based on the packet timing information.

Abstract: Systems and methods are provided for managing digital identities associated with users. One exemplary method includes receiving, at a computing device, an encrypted message from a communication device associated with a user where the messaging includes a changed attribute for the user. The method also includes generating a hash of a digital identity for the user with the changed attribute, generating a hash of the digital identity of the user stored in a ledger data structure, and transmitting a request for the user to attest to the changed attribute when the generated hashes do not match. The method then further includes broadcasting a pending status of the digital identity of the user to a relying party for the digital identity, and storing a certification of the changed attribute, received from the relying party in response to the pending status, based on verification of the changed attribute by the relying party.
