  • Publication number: 20190239037
    Abstract: A method and system are provided for sharing data amongst a group of a plurality of mobile devices without requiring a database or server to centrally store the shared data. The shared data is instead stored by each group member individually while controlling the manner in which the shared data is updated. The shared data can be used to manage tasks in a group project. To manage updates, the shared data is atomized such that individual databases in the shared data are separated or otherwise delineated into one or more records, each record having associated therewith, a value. To maintain a common copy of the shared data at each device, any update is sent to all group members using an intermediate message exchange service that is capable of transmitting a sent message to more than one recipient if necessary. In this way, the updates are multicast to the group. To manage the content of the shared data, each update comprises one or more changes to a current copy of a corresponding record.

  • Publication number: 20190080114
    Abstract: A system and method for selectively securing data from unauthorized access on a client device storing a plurality of data types with reference to an authorization level indicated in a command. A command is received at a client device comprising an authorization level indicator. Based on at least one predefined rule, which may be implemented in an IT policy stored at the client device, each of the plurality of data types to be secured is determined, and then the data corresponding to those types is secured. The data may be secured by encrypting and/or deleting the data at the client device. The predefined rules associated with each authorization level may be configured by a user or administrator having an authorization level that exceeds the associated authorization level.

  • Publication number: 20180330065
    Abstract: A novel code signing system, computer readable media, and method are provided. The code signing method includes receiving a code signing request from a requestor in order to gain access to one or more specific application programming interfaces (APIs). A digital signature is provided to the requestor. The digital signature indicates authorization by a code signing authority for code of the requestor to access the one or more specific APIs. In one example, the digital signature is provided by the code signing authority or a delegate thereof. In another example, the code signing request may include one or more of the following: code, an application, a hash of an application, an abridged version of the application, a transformed version of an application, a command, a command argument, and a library.

  • Publication number: 20180310164
    Abstract: A wireless device (WD) is associated with a preprogrammed user roaming setting and an automated adjustment algorithm stored in operative communication with the device. The algorithm is initiated and run when the device enters a roaming area, thereby automatically activating the roaming setting. A user response query is operatively connected to the automated adjustment algorithm, and operates as a switch for the automated adjustment algorithm, which initiates changing the user settings in accordance with the roaming setting. A user available query is connected to the user response query, to determine if the wireless device is in use, and to generate a notification if the device is idle or a prompt if the device is in use. An output from the switch of the user response query selectively enables the automated adjustment algorithm responsive to at least one of a responsive and a nonresponsive input to the user response query.

  • Patent number: 9768955
    Abstract: Systems and methods for providing additional security for data being transmitted across a wireless connection that has been established using a known wireless protocol (e.g. Bluetooth) are described. An encryption key is exchanged between a computing device (e.g. a mobile device) and a wireless peripheral device (e.g. a keyboard, a printer). In some embodiments, the encryption key is generated at one of the two devices. Data associated with the encryption key is output at the one device, which can be input by the user at the other device. The encryption key is then recovered at the other device from the input, thereby completing the key exchange. The encryption key can then be used to encrypt and decrypt data transmitted over the established wireless connection, providing additional security.

  • Patent number: 9699762
    Abstract: A mobile communications device receives and handles an encoded message. State data about the encoded message is generated based upon a first access of the encoded message. The device stores the generated message state data in a cache of the mobile communications device; generates a message indicator based upon the message state data stored in the cache of the mobile device; and processes the encoded message on a background thread running on the mobile device. The process determines that a message state change has occurred since the message was last opened and provides an updated message indicator to a user of the mobile device that reflects the message state change.
