  • Patent number: 9455830
    Abstract: A method of securing user credentials in a remote repository is provided. In accordance with one embodiment, there is provided a method comprising generating a first private key and a first public key pair from a registered password; generating a second private key and a second public key pair; generating a storage key from the second private key and the first public key; encrypting a set of credentials using the storage key; creating a encrypted credential signature from the encrypted set of credentials and the first private key; and storing the encrypted set of credentials, the encrypted credential signature, and the second public key in the remote repository.

  • Patent number: 9154939
    Abstract: A system and a method are provided managing services associated with a mobile device. It includes detecting a new identity module card is in the mobile device; receiving a username ID and a password on the mobile device; and upon verifying that the username ID and the password are identical to a previous username ID and a previous password associated with the mobile device, the mobile device enabling access to the services. In another aspect, after detecting a new identity module card, and if an input is received to associate a new username ID and a new password with the mobile device, then the services are erased from the mobile device.

  • Patent number: 8689299
    Abstract: Systems and methods for managing a user identity on a mobile device are provided. The system comprises the mobile device comprising a user agent and a client application, the user agent and the client application in communication with each other. The system further comprises an identity provider in communication with the mobile device, and a client service in communication with the mobile device. The user agent is configured to communicate with the identity provider and retrieve the user identity for the client application, and the client application is configured to transmit the user identity to the client service.

  • Patent number: 7721213
    Abstract: Information for configuring control apparatus for a power system including a plurality of controlled power supplies is produced using a graphical interface which displays the topology and sequencing of the power supplies in the power system. A database is used to select power supplies to add in determining the power system topology. Sequencing is represented by displacing icons representing the power supplies along lines representing their input and output voltages, and arrows representing startup sequence dependencies. A processor produces the configuration information, consistent with the displayed topology and sequencing, using information for the selected power supplies from the database, for downloading to the control apparatus.
