A method for effective vehicle identification and communication between riders of transportation network companies (TNC), and the vehicles that are being designated to the riders. Accordingly, a system used to execute the method of the present invention conveys the information of the rider on a display device on the designated vehicle of the rider, so as to notify the rider before getting into the designated vehicle. Additionally, the present invention also helps assist blind people by conveying audio messages, such as pipe messages or announcing their names. Further, the present invention provides riders the ability to send an emergency alert, thereby ensuring a safer ride. Furthermore, the present invention enables TNCs to utilize the display device as a trade dress and as an optional platform for other media advertisements.

A global resource locator (GRL) device can be used to track a physical asset. The GRL device can a semiconductor chip with a processor and a timing device. The semiconductor chip can generate a timing signal. The GRL device can include a blockchain, a communication device, and a memory in logical communication with the processor. The memory can store an identifier, a public key, a private key, and a hash. The communication device can communicate wirelessly with an authenticated radio source, the micro sized timing device, and the blockchain. Each authenticated radio source can be located at a respective reference location. The communication device can receive wireless timing signals from at least three authenticated radio sources. The GRL device can be affixed to a product.

A method for providing fixed-mobile convergence capabilities and/or device discovery capabilities within a telecommunications network includes: a specific client device or user equipment is connected to or connects to the home gateway device in order to connect to the telecommunications network; the home gateway device uses the connection to the specific client device or user equipment to initiate an exchange of messages according to an authentication or key exchange protocol, wherein the authentication or key exchange protocol is an extensible authentication protocol (EAP) or an enhanced authentication and key agreement (AKA), wherein identity information of the specific client device or user equipment is transmitted to the home gateway device as part of at least one message of the authentication or key exchange protocol; and the authentication or key exchange protocol is prematurely terminated.

An improved One Time Password (iOTP) is used in a two-factor authentication mechanism to decode a username, and the inherent security of the iOTP eliminates the need for a password. When the user is identified by the iOTP, a second challenge is sent. The second challenge may be confirmed by user biometrics or via a PIN code if the user's device does not support biometrics. Benefits of the subject invention include: (1) no username, which eliminates exposure to multiple domain attacks (i.e., attacks on other sites with the same username) that attempt to extract passwords from less secure sites (e.g., where a user used the same username and password across multiple sites); and (2) password-less access—the iOTP replaces both the username and password function, thereby eliminating the need for the user to manage multiple usernames and passwords.

This disclosure relates to a data storage device. A data port transmits data between a host computer system and the data storage device over a data channel. The device repeatedly broadcasts advertising packets over a wireless communication channel different from the data channel. Each advertising packet comprises a random value and a message authentication code calculated based on the random value and an identity key. The identity key is readable by a device to be connected and in proximity of the data storage device out of band of the data channel and the communication channel. The identity key enables the device to be connected to verify the message authentication code based on the random value and the identity key to thereby authenticate the data storage device.

Systems and methods of the present disclosure leverage distributed ledger technology (DLT) to provide decentralized control of cooperative tasks performed by a plurality of robots. Characteristics of the plurality of robots may be stored in a distribute ledger, which may be provided by a blockchain or a distributed database system. When a service request is received, a set of tasks may be identified for providing the requested service and the robot characteristics recorded to the distributed ledger may be used to identify a list of candidate robots possessing characteristics corresponding to the set of tasks may be identified. A smart contract may be utilized to select one or more candidate robots for performing the task and to verify the selected robot(s) successfully completed the task. State information associated with operation of the selected robot(s) may be monitored to verify task completion.

A first network device for use in a blockchain network is described. The first network device comprises means for, while carrying out a first iteration of a consensus protocol involving a second node device (103), in response to a trigger event (3040), obtaining a time interval function of a time interval start trigger event (3040) and of a time interval end trigger event (3080), each event being linked to a message of the consensus protocol and wherein at least the end trigger event (3080) comprises receiving a message from the second node device; means for transmitting (3083) first data (Delay_102) representative of said time interval to said second node device; means for, during a subsequent iteration of said consensus protocol involving said second node device, receiving a message (3140) from said second node device, said message containing second data (DelayTX_102) representative of said time interval from said second node device; means for authenticating said second node device as a function of said second data. A second network device, methods at the first and second network devices and a computer readable medium with code for carrying out the methods are also described.
