Abstract: Embodiments include a water collection device (100) comprising one or more water sorbing materials including at least a first thermo-responsive polymer that sorbs water at temperatures above an upper critical solution temperature and desorbs water below the upper critical solution temperature. Embodiments further include a method of harvesting water comprising exposing one or more water sorbing materials to an environment, wherein the one or more water sorbing materials includes at least a first thermoresponsive polymer that sorbs water at temperatures above an upper critical solution temperature and desorbs water at temperatures below the upper critical solution temperature; and collecting water desorbed from the at least first thermo-responsive polymer.

Abstract: A system administrator, while logged into a system-administrator account, creates and configures a key-administrator account and a member account. A key administrator, while logged into said key-administrator account, creates a group private key, a group public key, and a group symmetric key, a member private key, and a member public key. The key administrator encrypts the group private key with the group symmetric key, and encrypts said group symmetric key with the member public key. A publisher encrypts a document using the group public key. The publisher distributes the resulting encrypted group document so that it is accessible via said member account but not through said key-administrator account.

Abstract: An embodiment of the invention provides an apparatus and method for online data conversion. The apparatus and method are configured to read data that is overlapped by a window in a first position in a volume, convert the data into a converted text, write the converted text into the volume, and slide the window to a second position in the volume.

Abstract: In examples of the present invention, an executable seeks to access a data file. An executable identity based access control list is accessed to determine whether the executable should be allowed to access the data tile.

Abstract: A method and apparatus for managing encrypted data on a computer readable medium wherein an encryption key is determined for a received quantum of data. The quantum of data is encrypted according to the encryption key at a volume level when the quantum of data comprises volume data. The quantum of data is encrypted according to the encryption key at a file level when the data comprises file data. The encrypted data is then directed to a computer readable medium.
