    • A scheme for transferring files from a file server to a file requesting client, which enables request and transfer of files which are related to a user requested file at a time of transferring a user requested file. The file requesting client makes a file request indicating a desired file, and in response the file server transfers a file list of files related to the desired file indicated by the file request. Then, the file requesting client makes a transfer request requesting a transfer of files according to the file list, and in response the file server transfers the files requested by the transfer request. Alternatively, the file requesting client makes a request indicating a desired file, and in response the file server transfers a concatenated file formed by concatenating files related to the desired file indicated by the request. Then, the file requesting client extracts individual files from the concatenated file.
    • 用于将文件从文件服务器传送到文件请求客户端的方案,其能够在传送用户请求的文件时请求和传送与用户请求的文件相关的文件。 文件请求客户端发出指示所需文件的文件请求,并且作为响应,文件服务器传送与由文件请求指示的所需文件相关的文件的文件列表。 然后,文件请求客户端根据文件列表进行请求传送文件的传送请求,并且作为响应,文件服务器传送由传送请求请求的文件。 或者,文件请求客户端发出指示期望文件的请求,并且作为响应,文件服务器传送通过连接与请求指示的期望文件相关的文件形成的级联文件。 然后,文件请求客户端从连接的文件中提取单个文件。

    • A decryption key management scheme for a software distribution system utilizing the decryption key, which can enable the re-install of the software that was decrypted once by a proper procedure, without requiring a re-acquisition of the decryption key from the software vender, so that a user can freely delete and re-install the software that was properly obtained once. The decryption key is searched in a memory device of a user's computer, or acquired from a distribution source of the encrypted software when the decryption key is not found in the memory means. Then, the encrypted software is decrypted by using the obtained decryption key, and a decrypted software content is installed into the memory device, while the decryption key acquired from the distribution source is stored into the memory device, such that the decryption key stored in the memory device is utilizable in decrypting the encrypted software at a time of re-installing the encrypted software.
    • 一种利用解密密钥的软件分发系统的解密密钥管理方案,其能够通过适当的过程重新安装一次解密的​​软件,而不需要从软件供应商重新获取解密密钥,因此 用户可以自由地删除并重新安装正确获得的软件一次。 在用户计算机的存储器装置中搜索解密密钥,或者当在存储装置中没有找到解密密钥时,从加密软件的分发源获取解密密钥。 然后,通过使用所获得的解密密钥解密加密软件,并且将解密的软件内容安装到存储装置中,同时从分发源获取的解密密钥被存储到存储装置中,使得存储在 存储设备可用于在重新安装加密软件时解密加密的软件。

    • A data input/output management scheme suitable for protection of electronic writing data. Whether the data entered into the program is a protected data or not is judged, and when it is, at least the identifier for identifying the program is recorded as the protected data input record. Then, a data output is permitted when the identifier for identifying the program is not recorded in the protected data input record, while whether or not to permit a data output is judged according to at least a requested output target when the identifier for identifying the program is recorded in the protected data input record. For the writing data, the application program is authenticated, and the authentication result is stored in correspondence to an identifier for identifying the application program. Then, a request for access to writing data from the application program is permitted when the stored authentication result for the application program indicates a successful authentication for the application program.
    • 适用于保护电子书写数据的数据输入/输出管理方案。 判断输入到程序中的数据是否为受保护数据,至少将用于识别程序的标识符记录为受保护数据输入记录。 然后,当用于识别程序的标识符没有记录在受保护的数据输入记录中时,允许数据输出,而当用于识别程序的标识符时,至少根据所请求的输出目标来判断是否允许数据输出 被记录在受保护的数据输入记录中。 对于写入数据,应用程序被认证,并且认证结果对应于用于识别应用程序的标识符被存储。 然后,当存储的应用程序的认证结果指示应用程序的成功认证时,允许访问从应用程序写入数据的请求。
