    • A computerized process receives at a processor a request to restore a file to memory. One or more media types and one or more media residencies that are associated with a plurality of backups of the file are identified. Each of the media types and media residencies has a restore factor associated with it. A calculated restore factor is determined for each combination of media type and media residency using the restore factor of each media type and each media residency. A media type and a media residency are selected as a function of the calculated restore factor. The file is restored to memory using the selected media type and the selected media residency.
    • 计算机化过程在处理器处接收将文件恢复到存储器的请求。 识别与文件的多个备份相关联的一个或多个媒体类型和一个或多个媒体驻留。 每个媒体类型和媒体驻留都具有与之相关联的恢复因子。 使用每个媒体类型和每个媒体驻留的恢复因子,确定媒体类型和媒体驻留的每个组合的计算恢复因子。 作为计算的还原因子的函数选择媒体类型和媒体驻留。 使用所选的媒体类型和所选的媒体驻留,将文件恢复到内存。

    • A digital signature system includes a database holding access control rules that identify documents authorized users are allowed to have electronically signed and a signing system capable of receiving signature requests from a plurality of authorized users, each signature request including a document to be signed, wherein the signing system parses the document to be signed and compares information obtained thereby to the access control rules stored in the database to determine whether the authorized user is authorized to have the document signed, and wherein if it is determined that the authorized user is authorized to have the document signed, the signing system signs the document using authentication information unique to the signing system.
    • 一种数字签名系统,包括一个数据库,该数据库包含识别授权用户被允许进行电子签名的访问控制规则,以及一个能够从多个授权用户接收签名请求的签名系统,每个签名请求包括要签名的文档,其中, 签名系统解析要签名的文档,并将由此获得的信息与存储在数据库中的访问控制规则进行比较,以确定授权用户是否被授权签署文档,并且其中如果确定授权用户被授权具有 签署文件后,签名系统使用签名系统特有的验证信息对文档进行签名。

    • A system for efficiently storing application data which allows a practically infinite number of physically separate storage devices to be used as archival storage means by one or more application programs. Application data is organized among the devices such that files with a similar expiry date (that is the date beyond which the files are no longer required to be archived) are grouped together on the same physical device, such that after the expiry date the device used for such files may be erased and re-used. Optionally, files with particular content-types may be grouped on the same physical device, or among physical devices of the same type.
    • 一种用于有效地存储应用数据的系统,其允许实际上无限数量的物理上分离的存储设备被一个或多个应用程序用作归档存储装置。 应用程序数据在设备之间组织,使得具有相似有效期限的文件(即不再需要归档文件的日期)在相同的物理设备上分组在一起,使得设备使用的到期日期 对于这样的文件可能会被擦除并重新使用。 可选地,具有特定内容类型的文件可以分组在相同的物理设备上,或者在相同类型的物理设备之间。

    • A method and system of encrypting a Personal Identification Number (PIN) using a portable payment device includes a portable payment device in communication with a network and a payment processor, and may be configured to receive a first encryption key from the payment processor, to receive a PIN, to encrypt the PIN using the first key, and to provide the encrypted PIN to the payment processor in a form useable to process a payment authorization message or transaction request. The first key may be protected by cryptographic camouflaging using a password. The password may be received by the device and used to decamouflage the first key, and the decamouflaged first key may be used to encrypt the PIN. In one configuration, the first key may be a symmetric key, such that a PIN encrypted by the first key may be of a standard format usable in existing payment systems.
    • 使用便携式支付设备加密个人识别码(PIN)的方法和系统包括与网络和支付处理器通信的便携式支付设备,并且可以被配置为从支付处理器接收第一加密密钥以接收 PIN,以使用第一密钥加密PIN,并且以可用于处理支付授权消息或交易请求的形式向付款处理器提供加密的PIN。 第一个密钥可以使用密码加密伪装进行保护。 密码可以由设备接收并用于对第一密钥进行去装饰,并且被破坏的第一密钥可以用于加密PIN。 在一个配置中,第一密钥可以是对称密钥,使得由第一密钥加密的PIN可以是现有支付系统中可用的标准格式。
