    • According to one embodiment, a memory device includes a third partial key write module, an encryption key write module, and a decryption module. The third partial key write module is configured to combine a second partial key received from the current host device with the first partial key in the partial key memory device and to write a generated third partial key into the volatile memory after the device authentication. The encryption key write module is configured to combine the third partial key with the second user authentication information and to write a generated encryption key into the volatile memory after the user authentication. The decryption module is configured to decrypt the encrypted data based on the encryption key in the volatile memory based on a read request received from the current host device and to output obtained data to the current host device when the user authentication has succeeded.
    • 根据一个实施例,存储器件包括第三部分密钥写入模块,加密密钥写入模块和解密模块。 第三部分密钥写入模块被配置为将从当前主机设备接收的第二部分密钥与部分密钥存储器设备中的第一部分密钥组合,并且在设备认证之后将生成的第三部分密钥写入易失性存储器。 加密密钥写入模块被配置为将第三部分密钥与第二用户认证信息组合,并且在用户认证之后将生成的加密密钥写入易失性存储器。 解密模块被配置为基于从当前主机设备接收到的读取请求,基于易失性存储器中的加密密钥来解密加密数据,并且当用户认证成功时将获得的数据输出到当前主机设备。

    • Parts of documents are retrieved using the entire context of selected documents. Classification unit designation section performs the designation of a classification unit. A logical structure analysis section analyzes the logical structure of the documents read-in from a document storing section where the documents are stored. A fundamental vector generation section partitions the logical structure of the documents by means of the classification unit, extracts keywords, and generates fundamental vectors. A heading vector generation section extracts key words from the headings of the structural elements that are arranged in higher level of structure than the structural element of the classification unit that was the target of fundamental vector generation, and generates heading vectors. A vector synthesis section synthesizes fundamental vectors and heading vectors, and generates composite vectors. Composite vector maintenance section attaches the corresponding composite vectors to structural elements of the classification unit that were the target of composite vector generation and maintains the attached objects. A classification section classifies the structural elements of the documents of the classification unit based on the degree of similarity of the generated composite vectors. A display section displays the results of classification.
    • 使用所选文档的整个上下文检索部分文档。 分类单元指定部分执行分类单元的指定。 逻辑结构分析部分从存储文档的文档存储部分中分析读入的文档的逻辑结构。 基本向量生成部分通过分类单位分割文档的逻辑结构,提取关键字,生成基本向量。 标题向量生成部分从与作为基本向量生成的目标的分类单位的结构要素相比排列的结构要素的标题中提取关键词,生成向量向量。 矢量合成部分合成基本矢量和方向向量,并生成复合矢量。 复合向量维护部分将相应的复合向量附加到作为复合向量生成目标的分类单元的结构元素,并维护附着对象。 分类部根据所生成的复合矢量的相似度,对分类部的文档的结构要素进行分类。 显示部分显示分类结果。
