20130144845 | REMOVAL OF DATA REMANENCE IN DEDUPLICATED STORAGE CLOUDS - A method implemented in a computer infrastructure including a combination of hardware and software includes receiving from a local computing device a request to securely delete a file. The method also includes determining the file is deduplicated. The method further includes determining one of: the file is referred to by at least one other file, and the file is not referred to by another file. The method additionally includes securely deleting links associating the file with the local computing device without deleting the file when the file is referred to by at least one other file. The method also includes securely deleting the file when the file is not referred to by another file. | 06-06-2013 |
20140050369 | Image Advocacy in Portable Computing Devices - A mechanism is provided for identifying one or more eligible image candidates. Responsive to a determination that the storage of a recently captured image raising an allocated captured images memory space in a storage to a point that storage of a next captured image would raise the allocated captured images memory space in the storage above the predetermined threshold, a criteria group in a set of criteria groups is identified to utilize for identification of one or more images candidates from a set of stored images in the storage. The one or more images candidates from the set of stored images in the storage are identified utilizing one or more image identification criteria in the criteria group. The one or more image candidates are then presented to a user. | 02-20-2014 |
20140310455 | SYSTEM, METHOD AND COMPUTER PROGRAM PRODUCT FOR DEDUPLICATION AWARE QUALITY OF SERVICE OVER DATA TIERING - A method for ensuring compliance of service levels corresponding to file-system operations in a deduplicated, tiered storage system comprising storage devices of varying performance levels, each of the performance levels being associated with at least one service level, includes performing a deduplication remapping operation so that a data item corresponding to a higher service level, is stored as an original on a higher performance storage tier while duplicates of the data item corresponding to a lower service level exist in lower performance storage tier at least in part as pointers to the data item on the higher performance storage tier. | 10-16-2014 |
20150163449 | Image Advocacy in Portable Computing Devices - A mechanism is provided for identifying one or more eligible image candidates. Responsive to a determination that the storage of a recently captured image raising an allocated captured images memory space in a storage to a point that storage of a next captured image would raise the allocated captured images memory space in the storage above the predetermined threshold, a criteria group in a set of criteria groups is identified to utilize for identification of one or more images candidates from a set of stored images in the storage. The one or more images candidates from the set of stored images in the storage are identified utilizing one or more image identification criteria in the criteria group. The one or more image candidates are then presented to a user. | 06-11-2015 |
20160132897 | COPYRIGHT INFRINGEMENT PREVENTION - In an approach for determining printability of an electronic file, a computer electronically receives a file for printing. The computer parses the file for one or more of text, images, and formatting indicative of potential copyrighted material. The computer, in response to identifying any text, images, or formatting indicative of potential copyrighted material, identifies potential copyrighted material within the file. The computer determines whether the file may be printed based, at least in part, on the identified potential copyrighted material. In another approach for determining printability of an electronic document, a computer electronically receives a document for printing. The computer locates attributes associated with the document and stored in a separate database, which includes one or more of the following: ownership, licensing information, printability, and number of prints allowed. The computer determines the document is printable based on the attributes and prints the document. | 05-12-2016 |

20080256427 | SYSTEM, METHOD, AND SERVICE FOR PROVIDING A GENERIC RAID ENGINE AND OPTIMIZER - A generic RAID engine system accepts an access request, accepts a metadata input comprising a layout description and, optionally, a plurality of resource optimization objectives, accepts a dynamic input comprising a dynamic state of an I/O stack comprising the generic RAID engine and a fault configuration of a plurality of storage devices in the I/O stack, and accepts RAID code input comprising information about the RAID code used by the I/O stack. The metadata input, the dynamic input, and the RAID code input are utilized to transform the access request into individual device reads and individual device writes such that RAID code relationships for the storage devices are maintained at all times. An optional optimizer module selects strategies that meet the resource optimization objectives. | 10-16-2008 |
20080270704 | CACHE ARRANGEMENT FOR IMPROVING RAID I/O OPERATIONS - The embodiments of the invention provide a method, apparatus, etc. for a cache arrangement for improving RAID I/O operations. More specifically, a method begins by partitioning a data object into a plurality of data blocks and creating one or more parity data blocks from the data object. Next, the data blocks and the parity data blocks are stored within storage nodes. Following this, the method caches data blocks within a partitioned cache, wherein the partitioned cache includes a plurality of cache partitions. The cache partitions are located within the storage nodes, wherein each cache partition is smaller than the data object. Moreover, the caching within the partitioned cache only caches data blocks in parity storage nodes, wherein the parity storage nodes comprise a parity storage field. Thus, caching within the partitioned cache avoids caching data blocks within storage nodes lacking the parity storage field. | 10-30-2008 |
