G06F 15/16

US Classification:

709231

Abstract:

The present invention extends to methods, systems, and computer program products for using HyperText Transfer Protocol communication as a transport for bi-directional data streams.

International Classification:

H04L 9/32

US Classification:

726 4

Abstract:

The subject disclosure relates to authorization based on a determination of permissions that can be granted for an action(s) to be performed on a resource. The determination of the permission is based on a set of rules that represent a theory including a notion of trust that has been divided into different sized tables. The tables are utilized to evaluate two or more input claims and to facilitate a determination of whether access to at least one system resource is to be granted. The evaluation can include matching the two or more input claims to rows in the table, wherein access is allowed if a match is found.

Qian Wang - Mercer Island WA, US

International Classification:

H04L 29/06

US Classification:

726 3

Abstract:

Methods and systems for verifying whether a user requesting an online account is likely a human or an automated program are described. A request for an online account may be received from a mobile device. A human challenge-response test adapted for displaying on a mobile device is displayed on the mobile device. Upon viewing the human challenge-response test, the user enters the user's solution to the human challenge-response test on the mobile device. A response hash value is created based on the user's solution. The response hash value is sent to an account request server for verification.

Abstract:

Systems and methods are provided for merchant mobile acceptance of user device data. For example, a method comprises receiving encrypted user device data and reader metadata from a merchant mobile device, determining a device reader API and device reader encryption scheme using the device reader metadata, parsing the encrypted user device data using the device reader API to determine encrypted personal information, and decrypting the encrypted personal information using the reader encryption scheme.

International Classification:

H04B 1/40
H04L 12/40
H04L 29/06
H04L 9/08

Abstract:

A method for operating at least one node connected to a shared communication medium reduces or eliminates the ability of an adversary node to identify the at least one node based on transient signal characteristics of a signal that the at least one node generates when transmitting a bit through the shared communication medium. The method includes adjusting, with a controller in a first node, an impedance of a variable impedance circuit in the first node to a first impedance level that the controller determines randomly, the variable impedance circuit in the first node being connected to an output of a transceiver in the first node and to a shared communication medium, and transmitting, with the transceiver, a first data bit through the shared communication medium with the variable impedance circuit producing the first impedance level.

International Classification:

H04L 29/06
H04L 9/08

Abstract:

A method of operating at least one node in a communication network that uses a shared communication medium has been developed to reduce or eliminate timing side-channel attacks performed by an adversary that is connected to the shared communication medium. The method includes generating, with a controller in a first node, a first jitter time offset randomly generated from within a predetermined time range, and transmitting, with a transceiver in the first node, a first data bit through an output of the transceiver that is connected to a shared communication medium, the first data bit being transmitted at a first time corresponding to the first jitter time offset added to a first predetermined transmission time.

H04L 9/08

Abstract:

A method of operating at least one node in a communication network that uses a shared communication medium has been developed. The method includes adjusting, with a controller in a first node, a resistance of a first potentiometer in the first node to a first resistance level that the controller in the first node determines randomly, the first potentiometer in the first node being connected to an output of a transceiver in the first node and to a shared communication medium, and transmitting, with the transceiver in the first node, a first data bit through the output that is connected to the shared communication medium with the first potentiometer producing the first resistance level.
