Techniques for fraud monitoring and detection using application fingerprinting. As used herein, an “application fingerprint” is a signature that uniquely identifies data submitted to a software application. In an embodiment, a plurality of historical application fingerprints are stored for data previously submitted to a software application. Each historical application fingerprint is associated with one or more contexts in which its corresponding data was submitted. When new (i.e., additional) data is subsequently submitted to the application, a new application fingerprint is generated based on the new data, and the new application fingerprint is associated with one or more contexts in which the new data was submitted. The new application fingerprint is then compared with one or more historical application fingerprints that share the same, or substantially similar, context(s). Based on this comparison, a risk score is generated indicating a likelihood that the new data was submitted for a fraudulent / malicious purpose.

A computer system has one or more software context that share use of a memory that is divided into units such as pages. In the preferred embodiment of the invention, the context are, or include, virtual machines running on a common hardware platform. The context, as opposed to merely the addresses or page numbers, of virtual memory pages that accessible to one or more contexts are examined. If two or more context pages are identical, then their memory mappings are changed to point to a single, shared copy of the page in the hardware memory, thereby freeing the memory space taken up by the redundant copies. The shared copy is ten preferable marked copy-on-write. Sharing is preferably dynamic, whereby the presence of redundant copies of pages is preferably determined by hashing page contents and performing full content comparisons only when two or more pages hash to the same key.

A method and system performs parallel processing of asynchronous processes on ordered entities. A system focuses on the average time and variance of the variable time process. Each processor can run multiple contexts. The processing may be divided into a number of stages, each of which can be performed by each of the processors. A system also needs to ensure that the order of the entities is preserved as desired. This order may be maintained by performing some type of pre-processing on the entities to determine their order, and then not starting processing on an entity until the processing of any entity which must precede that entity has been completed. For processing of packets in a network, it may be needed to ensure that packets in the same flow maintain their order after processing. A system also may determine the number of processors that optimally are needed in order to process an incoming stream of entities at a desired speed. This computation may depend on how many different contexts each processor runs. In addition, this computation also may depend on whether there is an input buffer available to store the incoming entities, and the capacity of such an input buffer.

A storage target device controller (such as an embedded controller in a SCSI disk drive) processes multiple commands concurrently in accordance with the methods and structures of the present invention. Each command is stored within its own context within the target device controller to retain all unique parameters required for the processing of each command. Processing of multiple commands permits switching of command contexts within the target device to improve utilization of resources associated with the target device. For example, when a first, active, command context is prevented from further processing due to the status of the disk channel, an inactive command context may be swapped with the active command context to better utilize the host channel communication bandwidth. Similarly, a first active command context may be configured to automatically switch to a linked command context upon completion of processing to further ease management of multiple contexts. In a preferred embodiment of the present invention, a set of registers contain the active context while a second set of registers contains an inactive command context. The sets of registers are configured in such a way that the active and inactive context may be rapidly switched with no intervention by the microprocessor. The inactive register set may be read or written directly by the microprocessor, or may be automatically loaded / stored from / to a buffer memory in the target device by shifting a predetermined context structure into the inactive register set through an interface pad with the buffer memory.

The invention provides a technique for managing multiple contextual views of source code files. In a file system, different tasks demand that source code files be grouped in different hierarchical directories. When some or all of this manipulation is of the physical files themselves, the directories can become confused, and it may be difficult for the next user to access needed source code files. In the technique of the invention, the physical location of the files is independent of all contextual views, and is maintained in a separate viewable hierarchy. All items in contextual view hierarchies contain only references to the physical location of the source code files, and so modifications of those items, such as delete, move and copy, only alter the references themselves. A separate set of operations can be used for explicitly maintaining or modifying the physical source code files.

The context list includes parameters that specify task priority and resource requirements for each context. The GPU includes a scheduler component that determines the availability of system resources and directs execution of commands to the appropriate system resources, and in accordance with the priority defined by the context list.

Some aspects relate to systems and methods of tagging to enhance contextualization of media items and ease of use. Tag data structures provide an extensible platform to allow description of a concept from multiple points of view and in multiple contexts, such as locations, activities, and people. Individual application instances using these data structures can each maintain a private store of media items, and can be synchronized with a server. Each application owner can select portions of the private store to share. The server also can maintain canonical hierarchies of tags, such as hierarchies of activities and of places. These canonical hierarchies can be provided to application instances, where private modifications / additions can be made. Owners can offer to share private modifications, which can be accepted or rejected. Displays of media item selections and of clouds of related tags can be formed based on the contextual and relational information contained in the tags and in the canonical hierarchies.

Techniques are disclosed for detecting and resolving conflicts in context information from various sources. That information may be used to automatically update one or more context sources and / or to validate or invalidate (until further notice or for a period of time) input from one or more context sources. Or, the updates can be made in response to the user's instructions. Rules are used in preferred embodiments to dictate the conflict resolution approach for individual users. Updating the context source is particularly useful when the source is an electronic calendar. Updates that may be made to the calendar include adding, deleting, or changing scheduled events and / or working hours. Invalidating data from a context source is particularly useful for lost, forgotten, misplaced, or loaned devices. Marking data from a context source as valid is preferably done when harmony among several context sources is detected. Context suppliers may be notified of errors or discrepancies in their context data.
