Abstract: Peer-to-peer redundant file server system and methods include clients that determine a target storage provider to contact for a particular storage transaction based on a pathname provided by the filesystem and a predetermined scheme such as a hash function applied to a portion of the pathname. Servers use the same scheme to determine where to store relevant file information so that the clients can locate the file information. The target storage provider may store the file itself and/or may store metadata that identifies one or more other storage providers where the file is stored. A file may be replicated in multiple storage providers, and the metadata may include a list of storage providers from which the clients can select (e.g., randomly) in order to access the file.

Abstract: Authentication involves collecting information relating to a user's behavior relative to a mobile device carried by the user, over a number of time periods that correspond to each other. An authentication technique includes processing the collected information to generate baseline data representing typical user behavior. The authentication technique includes collecting additional information relating to the user's behavior relative to the mobile device over another time period that corresponds to the time periods used to generate the baseline data. The additional information relating to the user's behavior is compared to the baseline data, and a difference between the additional information and the baseline data is determined. An authentication procedure is then applied based on the difference. The authentication may be performed by a mobile device such as a smartphone.

Abstract: A mobile device operates in a standard mode of operation, or operates in a visually impaired (VI) mode of operation designed for visually impaired users and in which a display screen of the mobile device is turned off by default. The display screen may thus remain turned off in the VI mode even when conditions under which the display screen is turned on in the standard mode are satisfied. The display screen may further remain turned off in the VI mode even when conditions under which a touch-screen input interface of the mobile device is turned on in either of the standard and VI modes. The mobile device may be configured to automatically transition from the VI mode to the standard mode in response to detecting a gaze directed towards the display screen.

Abstract: A charger and a mobile device exchange messages indicating that high wattage charging is supported over a bidirectional communication channel. After the message exchange, the charger sends a controlled output voltage and current to the mobile device over a cable connected between the charger and the mobile device. The mobile device takes an input voltage measurement that corresponds to the controlled output voltage after being passed through the cable. The charger or mobile device may then calculate a resistance of the cable based on a difference between the controlled output voltage and the input voltage measurement. Based on the resistance of the cable, the controlled voltage and current used to charge a battery of the mobile device is adjusted in order to avoid exceeding capacity of the cable.

Abstract: To virtually transfer subscriber identity module (“SIM”) credentials from an active device to an inactive device in order to share carrier network access, temporary identifiers and SIM credentials are transferred using secure connections and an optional public-private key pair with encryption at the transport layer. In an example, a carrier identification (“ID”) server receives a temporary identifier, such as a temporary international mobile subscriber identity (“TIMSI”), from an inactive device via a carrier network. The carrier ID server authenticates the inactive device using the TIMSI by issuing a network challenge. Next, the carrier ID server verifies with an active device associated with the inactive device that the active device distributed the TIMSI. After authenticating and verifying with both devices, the carrier ID server activates the inactive device by allowing the TIMSI to behave as virtual SIM credentials on the carrier network.

Abstract: Systems and methods for managing information about content transmission are disclosed. In some implementations, a first mobile device communicates with a second mobile device, via a short-range radio of the first mobile device, to either send or receive a content item. The first mobile device tags the content item with a tag. The tag identifies the second mobile device. The first mobile device transmits to a server, via an additional radio of the first mobile device, data identifying the content and the second mobile device. The additional radio is different from the short-range radio. The data is transmitted to the server for analyzing short-range radio transmissions between mobile devices.

Abstract: A block grouping method for a solid state drive includes the following steps. Firstly, plural blocks are classified into a high valid data count group and a low valid data count group according to valid data counts of respective blocks. An average erase count is set according to a specified number of blocks of the low valid data count group. A first block is selected from the high valid data count. A difference between the average erase count and a first erase count of the first block is calculated. If the difference exceeds a threshold value, a wear leveling operation is performed on the first block.
