Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for secure authentication using puncturing. An authentication system receives an encoded obfuscated authentication credential as part of an authentication request and accesses a stored authentication credential. The authentication system performs a puncturing of the encoded obfuscated authentication credential. The resulting punctured authentication credential includes a subset of individual values from the encoded obfuscated authentication credential. The authentication determines whether the punctured encoded data input corresponds to at least a portion of the stored authentication credential. In response to determining that the punctured encoded data input corresponds to at least a portion of the stored authentication credential, the authentication system approves the authentication request.

Abstract: Techniques and systems are disclosed to enable location verification and tracking, for use or access of a geographic-specific phone number or similar location feature of a communications service by a mobile computing device at (or within) a geographic location or defined area. In an example, verification of a use of the device at the location or area is enabled by the receipt and collection of location verification data for a token having location verification and time data, with such location verification data being communicated via a short-range wireless network. The verification is enabled by communication of the token to a communications service for device identification and location registration, and assess to a resource based on registered use of the communications device at the geographic location. In further examples, capabilities for security, verification, and auditing of location information is enabled with use of the token and location information.

Abstract: Disclosed in some examples are systems, methods, devices, and machine-readable mediums for improved communications between a software-defined radio front-end device and a network-based computing device. Rather than packetize samples together, same bit positions from multiple ADC samples may be packetized together. If a Quality of Service (QoS) metric of the network connection between the RF front-end device and the network-based processing computing drops below a threshold, the RF front-end device may prioritize sending packets with the more significant bits over packets with less significant bits. In other examples, the RF front-end device may prioritize samples corresponding to certain data types over other data types.

Abstract: Disclosed in some examples are methods, systems, and machine-readable mediums that assign a same identifier to a plurality of a user's communication devices. A communication server alerts only one device of the plurality of communication devices at a time in response to a communication establishment request from a calling communication device directed to the identifier. If the user fails to answer the alert, another device is chosen and alerted according to a particular sequence of devices until the user either answers or until all devices (or a determined subset of devices) have been tried. In some examples, the communication devices are reachable by the communication service via an alternative address known to the communication server, such as an Internet Protocol (IP) address.

Abstract: Disclosed in some examples are methods, systems, devices, and machine-readable mediums that detect evil twin and other anomalous access points in an IT infrastructure by detecting access points that are not in their expected locations based upon an analysis of access point reports from one or more computing devices.

Abstract: Disclosed in some examples are methods, systems and machine-readable mediums which allow for more secure authentication attempts by implementing authentication systems with credentials that include interspersed noise symbols in positions determined by the user. These systems secure against eavesdroppers such as shoulder-surfers or man-in-the middle attacks as it is difficult for an eavesdropper to separate the noise symbols from legitimate credential symbols.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for symmetric cryptography using varying sized symbol sets. To protect against a brute force or other similar type of attack, multiple symbol sets of varying sizes can be used for encrypting/decrypting data. For example, different portions of the data (e.g., data blocks representing multiple symbols, set of bits representing a single symbol) may be encrypted/decrypted using different symbol sets that include different numbers of unique symbols. Using varying sized symbol sets adds additional complexity to the encryption process, thereby greatly increasing the difficulty in decrypting the encrypted data with a brute force attack.

Abstract: Systems and methods may be used for providing a location of a device during an emergency communication. These systems and methods may include operations (e.g., performed by a processor), including detecting that an emergency service call has been started at the device, and initiating a digital assistant in response to detecting that the emergency service call has been started. The systems and methods may include operations including parsing audio during the emergency service call to determine a request for location information, and providing audio, by the digital assistant during the emergency service call, indicating a location based on location information determined at the device.

Abstract: Systems and methods may be used for providing more secure authentication attempts by implementing authentication systems with credentials that include interspersed noise symbols in positions selected, for example by a user. These systems and methods secure against eavesdroppers such as shoulder-surfers or man-in-the middle attacks as it is difficult for an eavesdropper to separate the noise symbols from legitimate credential symbols. Some systems and methods may use a subset of a credential with the interspersed noise symbols.

Abstract: Techniques for providing network connection plans for computing devices planning to travel along a pre-specified route are disclosed herein. In an example, crowd-sourced data is used to generate a network map that includes network parameters mapped to one or more geographical locations. The network map is used to generate a network connection plan for a computing device planning to travel along a pre-specified route. The computing device may then connect to one or more wireless networks according to the network connection plan while traveling along the pre-specified route.

Abstract: Disclosed in some examples are display systems, methods, devices, and machine-readable mediums which provide for a gesture-based method for specifying a region of a display in which to show shared content.

Abstract: Disclosed in some examples are methods, systems, devices, and machine-readable mediums which encode data into a geometric representation for more efficient and secure processing. For example, data may be converted from a binary representation to a geometric representation using an encoding dictionary. The encoding dictionary specifies one or more geometric shapes used in the encoding. The geometrically encoded data may comprise one or more identifiers that specify one or more of the shapes of the encoding dictionary that best match one or more detected features in an image corresponding to the data. In some examples, the geometrically encoded data may also comprise one or more transformations of the one or more shapes to reduce error in the geometric encoding.

Abstract: Disclosed in some examples are methods, systems, devices, and machine-readable mediums which optimize one or more metrics of a communication system by intentionally changing symbols in a bitstream after encoding by an error correction coder, but prior to transmission. The symbols may be changed to meet a communication metric optimization goal, such as decreasing a high PAPR, reducing an error rate, reducing an average power level (to save battery), or altering some other communication metric. The symbol that is intentionally changed is then detected by the receiver as an error and corrected by the receiver utilizing the error correction coding.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for improved data transmissions using puncturing and binary sequences. A receiving device receives a sequenced data input that includes a set of individual values and performs a puncturing of the sequenced data input, yielding a punctured sequenced data input.
