摘要： Method and apparatus for transactional fault tolerance in a client-server system is described. In one example, output data generated by execution of a service on a primary server during a current epoch between a first checkpoint and a second checkpoint is buffered. A copy of an execution context of the primary server is established on a secondary server in response to the second checkpoint. The output data as buffered is released from the primary server in response to establishment of the copy of the execution context on the secondary server.

摘要： A system and method for efficiently reducing a number of duplicate blocks of stored data. A file server both removes duplicate data and prevents duplicate data from being stored in the shared storage. A sampling rate may be used to determine which fingerprints, or hash values, are stored in an index. The sampling rate may be modified in response to changes in characteristics of the system, such as a change in the shared storage size, a change in a utilization of the shared storage, a change in the size of the storage unit, and reaching a threshold corresponding to utilization of the index. Also, a small cache may be maintained for holding fingerprint and pointer pair values prefetched from the shared storage. Each prefetched pair may be associated with data corresponding to a previous hit in the index. The association may be related to spatial locality, temporal locality, or otherwise.
摘要翻译：一种用于有效地减少存储数据的多个重复块的系统和方法。文件服务器同时删除重复数据，并防止重复数据存储在共享存储中。可以使用采样率来确定哪些指纹或散列值存储在索引中。可以响应于系统特性的变化来修改采样率，例如共享存储大小的变化，共享存储器的利用率的改变，存储单元的大小的变化以及达到阈值对应于索引的利用。此外，可以维护小的缓存以保持从共享存储器预取的指纹和指针对值。每个预取对可以与对应于索引中的先前命中的数据相关联。该关联可能与空间局部性，时间局部性或其他方面有关。

摘要： A method processing one or more files using a security application. The method includes a method processing one or more files using a security application. The method includes connecting the client to a proxy server, which is coupled to one or more NAS servers. The method includes requesting for a file from a client to the proxy server and authenticating a requesting user of the client. The method also includes authorizing the requesting user for the file requested; requesting for the file from the one or more NAS servers after authenticating and authorizing; and requesting for the file from the one or more storage elements. The file is transferred from the one or more storage elements through the NAS server to the proxy server. The method determines header information on the file at the proxy server and identifies a policy based upon the header information at the proxy server. The method also includes processing (e.g., decompressing the file, decrypting the file, and verifying the file) the file according to the policy. The method includes transferring the processed file to the user of the client.

摘要： A host validation system runs on a portable storage device, and protects data stored thereon from unauthorized access by host computers. The system identifies a host to which the portable device is coupled, for example by using the host's TPM. This can further comprise identifying the host's current configuration. The system uses the identification and configuration information to verify whether the host is approved to access data stored on the portable device. The system provides the host a level of data access responsive to this verification. This can involve denying all data access to the host, or providing at least some access to data stored on the portable device, for example based on a stored access policy specifying levels of access to provide to specific hosts with specific configurations.

摘要： A system and method for providing for the secure and protected processing of securities transactions, particularly preventing the alteration or deletion of trades in violation of the SEC rules. A secure relational database stores, protects and verifies information regarding submitted securities transactions. As transactions are created during normal business processing, they are passed through a computer system, either using real-time or batch interfaces. All transactions stored in the vault are time-stamped, encrypted and tagged for later validation. By using sophisticated, industry-accepted methods for tagging and protecting the integrity of the data, the invention ensures the integrity of each transaction and that system rule have been enforced and applied consistently. The system can be implemented in conjunction with a variety of recordkeeping systems and proprietary platforms, including but not limited to SunGard's OmniPlus system, Relius, TrustMark WyStar and proprietary platforms.
摘要翻译：一种用于提供安全和受保护的证券交易处理的系统和方法，特别是防止违反SEC规则的交易的更改或删除。安全关系数据库存储，保护和验证有关提交的证券交易的信息。由于事务在正常业务处理期间创建，因此它们通过计算机系统传递，无论是使用实时还是批处理接口。存储在保管库中的所有事务都经过时间戳，加密和标记，以供稍后验证。通过使用复杂的行业接受的方法来标记和保护数据的完整性，本发明确保每个事务的完整性，并且该系统规则已经被强制执行并被一致地应用。该系统可以与各种记录系统和专有平台相结合实现，包括但不限于SunGard的OmniPlus系统，Relius，TrustMark WyStar和专有平台。

摘要： A method for securing transaction data of a financial services organization such as a mutual fund is provided. The transaction data is produced in response to orders placed by customers in a transaction creation system of the financial services organization. The transaction data is delivered from the transaction creation system into a transaction gateway before it is sent to a financial processing system. The transaction gateway processes the transaction data in order to generate a unique secure transaction token. A transaction vault is provided for storing and maintaining secure transaction tokens. The transaction gateway may also optionally produce a cumulative secure transaction token. The tokens provide a reference point for customers or regulators to determine whether any individual orders have been modified, or whether any cumulative orders have been improperly deleted.
