摘要： The invention provides a method and system for managing data access. The method includes receiving a request for accessing a file, determining a type of the received request that corresponds to an access pattern based on history of many files, marking the request based on the type of request to identify the request as a candidate to be part of a sequential scan for accessing files in a sequential order, and processing the request based on the marking to throttle access of the file in the case of a potential ongoing erroneously requested sequential scan.
摘要翻译：本发明提供了一种用于管理数据访问的方法和系统。该方法包括接收访问文件的请求，基于许多文件的历史来确定与访问模式相对应的接收到的请求的类型，基于请求的类型来标识请求以将请求标识为候选者用于按顺序访问文件的顺序扫描，以及在潜在的正在进行的错误请求的顺序扫描的情况下，基于标记来处理该请求以节省文件的访问。

摘要： A correctness verification system receives a query, executes the query using a query logic, and produces a query result. The query result comprises data records that satisfy the query, data verification objects associated with the data records, index segments accessed during the execution of the query, index verification objects associated with the index segments, and the query. The system transfers the query result to a verification system. The verification system verifies correctness of the query result by executing the query using the query logic. The verification system uses the data verification objects to verify integrity of the data objects, uses the index verification objects to verify the integrity of the index segments, and uses the index verification objects and the data verification objects to verify the completeness of the query result.

摘要： Files are encrypted and stored on a WORM media device along with their encryption keys, the binary values of which are stored as a combination of written and unwritten sectors in a key storage portion of the media. To shred a file, the associated key is destroyed simply by writing into the unwritten sectors that are associated with the key.

摘要： An object storage system provides a storage object to support index structures, logs, and audit trails in WORM storage. The storage object includes a mutable object, an immutable object, or an appendable object. For each storage object, the system maintains an indication of type, such as mutable, immutable, or appendable object type. A mutable object can be arbitrarily modified, an immutable object cannot be modified, and the contents of the appendable object cannot be modified but can be appended with new data. Appended data becomes immutable. The system enables a protection level represented by the object type to be upgraded but not downgraded. Consequently, data committed to be immutable cannot be changed by changing the type of the storage object.
摘要翻译：对象存储系统提供一个存储对象来支持WORM存储中的索引结构，日志和审计跟踪。存储对象包括可变对象，不可变对象或可追加对象。对于每个存储对象，系统维护类型的指示，例如可变的，不可变的或可追加的对象类型。可变对象可以任意修改，不可修改的对象不能被修改，并且可追加对象的内容不能被修改，而是可以附加新的数据。附加数据变得不可变。该系统使得由对象类型表示的保护级别能够升级但不降级。因此，不能通过更改存储对象的类型来改变承诺为不可变的数据。

摘要： A data migration system performs a tamper-resistant data migration for regulatory compliance systems. The system generates a secure hash for the data object, adds a timestamp to the hash, produces a signature for the data object using a private key, and includes the signature in a signature summary of data objects. Immediately prior to data migration, the system signs the signature summary of the set of data objects to be migrated. The signature of the data object maintains integrity of the data object by preventing undetectable modification to a data object during migration. The signed signature summary maintains completeness by preventing undetectable removal of a data object from or insertion of a data object into the set of data objects during migration.
摘要翻译：数据迁移系统对监管合规系统执行防篡改数据迁移。系统为数据对象生成安全散列，向散列添加时间戳，使用私钥生成数据对象的签名，并将签名包含在数据对象的签名摘要中。在数据迁移之前，系统将签署要迁移的数据对象集合的签名摘要。数据对象的签名通过在迁移期间阻止对数据对象的不可检测的修改来保持数据对象的完整性。签名签名摘要通过在迁移期间防止将数据对象从数据对象或数据对象插入到该组数据对象中而无法检测到的完整性。

摘要： The present invention relates to a method for proving the correctness of a query result produced by a data publisher while preserving the privacy of the query result. The method comprises delivering a public key of a public key/private key pair from a data owner to a client and delivering data and cryptographic metadata to at least one data publisher, wherein the metadata is associated both with the data and the public key of the public key/private key pair. The method further comprises receiving a query from the client, returning a query result and a verification object from the data publisher to the client in response to the query, and verifying the correctness of the query result, wherein the correctness of the query result is verified utilizing the verification object and the public key.
