摘要： A method for information flow tracking is provided using, for example, a functional programming language based on lambda calculus, λI. The method provides a unified information-tracking framework that supports multiple, interdependent dimensions of information. An expressive policy-specification system is separated from the underlying information-flow tracking mechanism. Arbitrary domain-specific policies are supported that can be developed and enforced independent of information flow tracking. Information-flow metadata is treated as a first-class entity, and information flow is correctly tracked on the metadata itself. Classes of information flow polices are defined using multiple dimensions that are application to both information flow data and to the information flows themselves. These classes of polices accurately model more realistic security policies, based on partial trust relations. Therefore, multiple interdependent dimensions of information are simultaneously tracked and enforced within the framework of the information flow tracking system.
摘要翻译：使用例如基于λ演算的功能编程语言λI来提供用于信息流跟踪的方法。该方法提供统一的信息跟踪框架，可以支持信息的多个相互依赖的维度。一个表达性的政策规范系统与基础的信息流跟踪机制分开。支持任意域特定策略，可独立于信息流跟踪开发和实施。信息流元数据被视为第一类实体，信息流在元数据本身上被正确跟踪。使用多个维度来定义信息流策略的类别，这些维度应用于信息流数据和信息流本身。这些政策类别基于部分信任关系准确地模拟了更为现实的安全策略。因此，在信息流跟踪系统的框架内，信息的多个相互依存的维度被同时跟踪和执行。

摘要： A computing device receives data access records and determines a user data access behavior pattern for a user based on the data access records. The computing device receives new data access records and identifies any deviation from the user data access behavior pattern based on the new data access records. Upon identifying deviation from the user data access behavior pattern, the computing device generates an alert indicating that the user has deviated from the user data access behavior pattern.

摘要： A method of maintaining and providing information relating to file deduplication. A first portion of a first file and a second portion of a second file that contain a first content are identified. A first header associated with the first portion is created. The first header identifies the first portion and the second portion containing the first content. The first header is appended to a storage location of the first content of the first portion to form a first data structure for the first file. The first data structure is stored. The first data structure is provided to an application requesting the first file so that duplicate data processing can be avoided by the application. The first data structure is updated when the first file or the second file are altered. A similar process may occur to generate a data structure for the second file.

摘要： A method for identifying data for relocation in a multivolume file system. The method includes generating a file location map, the file location map containing a list of the locations of files that occupy space on each of a plurality of volumes of the file system, wherein The file system comprising least a first volume and a second volume. The method further includes updating the file location map in accordance with changes in a file change log for the file system, and identifying data residing on the first volume of the file system by scanning the file location map. Using the identified data, a ratio of per-file activity during a first time period relative to overall file system activity over a second time period is calculated to derive a file activity ratio for each of the files of the identified data. Files are then selected for relocation based on the file activity ratio.

摘要： Various systems and methods use advisory metadata to track the status of file system objects. For example, one method can involve accessing a first item of advisory metadata, which is associated with a namespace-visible parent directory and identifies a first transaction and a first time, and accessing a second item of advisory metadata, which is also associated with the namespace-visible parent directory and identifies a second transaction and a second time. The namespace visible parent directory includes multiple namespace-hidden directories. The method can then select a time value of the advisory metadata for the namespace-visible parent directory, based upon the first item and the second item. The method can be performed by a computing device implementing a file system.

摘要： A method of partitioning directory. Accesses, e.g., shared/exclusive, and/or waiting requests, e.g., shared/exclusive, to access one or more files with a directory are monitored, e.g., incrementing/decrementing respective counters. The waiting requests are queued to be granted at a later time. The directory is determined to be primed for partitioning if a number of waiting requests to access the directory is greater than a threshold value of a plurality of heuristics and optionally further based on satisfying the condition for at least a programmable time threshold period. A trigger signal is automatically generated if the directory is primed for partitioning. The trigger signal causes a file system to partition the directory. It is appreciated that the plurality of heuristics is user programmable.

摘要： A region of memory is logically divided into a number of segments, each of which is logically divided into a number of blocks. Blocks are allocated sequentially. A head pointer and a tail pointer demarcate the section of allocated blocks. As allocated blocks are added, the tail pointer is moved so that it remains at the end of the section of allocated blocks. If the tail pointer is within a threshold distance of the head pointer, then the head pointer is moved from its current position to a new position, and the allocated blocks between the current and new positions are freed (deallocated and/or erased). Thus, writes to the memory can be performed sequentially, and blocks can be freed in advance of when they are actually needed.
摘要翻译：存储器区域在逻辑上被划分成多个段，每个段在逻辑上被划分成多个块。块按顺序分配。头指针和尾指针划分分配块的部分。当分配的块被添加时，尾部指针被移动，使得它保持在分配块的部分的末尾。如果尾指针在头指针的阈值距离内，则头指针从其当前位置移动到新位置，并且释放（释放和/或擦除）当前位置和新位置之间的分配块。因此，可以顺序地执行对存储器的写入，并且块可以在实际需要时被释放。
