Abstract: A computer implemented method searches data. A number of processor units generates a candidate search result using an index for a data source in response to a search query by a user, wherein the candidate search result comprises files accessible by the user based on access control information in the index. The number of processor units generates a completed search result with a set of the files from the candidate search result having a confidentiality level less than or equal to a threshold confidentiality level. The number of processor units determines whether the user has access to a file in the candidate search result in which the file has the confidentiality level greater than the threshold confidentiality level for the data source. The number of processor units adds the file to the completed search result in response to the file being accessible by the user in the data source.

Abstract: In an approach to improve magnetic tape file systems through tape-to-tape copying between nodes on a Linear Tape File System using a cluster-wide named pipe. Embodiments transfer data between a first node and a second node. Additionally, both the first node and the second node implement a parallel shared-disk file system through a data path for node data reading and writing from a shared-disk and to the shared-disk. Further, to transfer data between the first node and the second node, embodiments, write, by the first node, the data for tape-to-tape copy from a first tape drive to the shared-disk, and write, by the second node, the data written from the shared-disk to a second tape drive.

Abstract: A tool for tape library hierarchical storage management. The tool determines there is available tape capacity on a tape cartridge mounted to a tape drive to migrate data from a migration queue during recall operations. The tool sends a locate end of data (EOD) command to the tape drive. The tool determines the migration queue is within a longitudinal position (LPOS) range. The tool writes data from the migration queue to the tape cartridge within the LPOS range.

Abstract: A method for authentication is provided. The method includes storing, by a first electronic device, first path information in a memory. The first path information includes data representing a first path of input on a touch interface associated with the first electronic device. One or more first portions of the first path information are communicated to a second electronic device. One or more second portions of second path information are received from the second electronic device. The one or more second portions are compared to the first path information. The second electronic device is authenticated based on similarity between the one or more second portions and the first path information. The method may allow for separate authentication to be performed by each device.
