  • Patent number: 10291404
    Abstract: Methods for supplying deficiency of a key in a set of keys stored in devices includes receiving information (key values) on the keys from each device. Each key is assigned to a node or pair of nodes in a tree structure(s). If a position of a key in the tree structure in a first set of keys is stored in a first device with its value and corresponds to a position of a key in the tree structure in a second set of keys stored in a second device with its value, the first device and the second device are grouped together. Where there is a missing key in the first set of keys, a key corresponding to the missing key from the second set of keys is found, or a key common in the first set of keys and the second set of keys is found.

  • Patent number: 10171981
    Abstract: A method for emergency communication includes encoding a message for visual display including a message to field and a message from field. The visual display is revealed to a reading device in communication with a broadcast center, which stores the visual display. The messages are decoded and sorted from visual displays at the broadcast center. On an index channel, a time and channel number for when a message body of the message will be broadcast on a message channel is broadcasted. The message body is broadcasted on the message channel.

  • Publication number: 20180322160
    Abstract: Verified snapshots are generated by obtaining, from one of a plurality of first nodes, a difference between a common data at a first time point and the common data at a second time point that is different from the first time point, generating a first snapshot of the common data at the first time point based on the difference, obtaining a hash of the common data at the first time point from one of the plurality of first nodes, and verifying the first snapshot at the first time point with the hash of the common data at the first time point.

  • Publication number: 20180089464
    Abstract: A method and system are provided. The method includes separating initial user-inputted data into terms. The method further includes determining which terms are identity-related terms relating to an identity of a user, and which terms are clarity-related terms relating to subject-matter clarity. The method also includes calculating a population. The population is a number of individuals satisfying the identity-related terms. The method additionally includes assigning, for each clarity-related term, a clarity level, representing a respective amount of clarity for a respective one of the clarity-related terms. The method further includes creating amended user-inputted data by amending the initial user-inputted data such that the population is greater than or equal to a first threshold, and such that the clarity level, assigned for each clarity-related term, is greater than or equal to a second threshold.

  • Publication number: 20180075261
    Abstract: A computer implemented method for managing a content processed by a device includes: enabling a first content to be written to the device, the first content having been obtained using a first encrypted content and a device key in the device, the first encrypted content having been obtained using the first content and the device key outside the device, the device key being unique to the device and set in the device. The method further enables a second content to be read from the device, the second content having been obtained using a second encrypted content and the device key outside the device, the second encrypted content having been obtained using the second content and the device key in the device, the second content having been obtained using the first content in the device.
