    • A method and system for controlling disclosure of trace data related to moving object. The method includes the steps of: receiving, for at least one moving object in a first region, a first record aggregate; receiving, for at least one moving object in a second region, a second record aggregate; calculating trace data from at least one attribute value of a first identifier that is in received first and second record aggregates in response to data search request; calculating to satisfy a condition of the moving object passing through at least one region and to satisfy another condition of at least two of the moving objects being present in each of the region; and returning calculated trace data as a search result if the moving object moves in calculated ranges and if the moving object has the first identifier that is in both the received first and second record aggregates.
    • 一种用于控制与移动物体相关的跟踪数据的公开的方法和系统。 该方法包括以下步骤:为第一区域中的至少一个移动对象接收第一记录聚合; 为第二区域中的至少一个移动物体接收第二记录聚合体; 响应于数据搜索请求,从接收的第一和第二记录聚合中的第一标识符的至少一个属性值计算跟踪数据; 计算以满足通过至少一个区域的移动物体的条件,并且满足存在于每个区域中的至少两个移动物体的另一条件; 以及如果所述运动对象在计算范围内移动并且所述移动对象具有处于接收到的第一和第二记录聚合中的第一标识符,则返回计算的跟踪数据作为搜索结果。

    • A database search system ensures the privacy of a search request and the security of a database with high processing efficiency. The system comprises a database server residing on a network that stores predetermined data, and a client terminal issuing to the database server a search request for inquiring for desired data while keeping the desired data secret. The database server further comprises: a database storing predetermined data; and a search response message generation unit for receiving through a network the data search request in which data to be searched for is kept secret, searching the database by a predetermined computation based on the search request and a list of the data stored in the database while a data item involved with the search request is kept secret, and generating a response to the search request.
    • 数据库搜索系统确保搜索请求的隐私和高处理效率的数据库的安全性。 系统包括驻留在存储预定数据的网络上的数据库服务器,以及客户端终端向数据库服务器发出查询请求以寻求期望数据同时保持所需数据的秘密。 数据库服务器还包括:存储预定数据的数据库; 以及搜索响应消息生成单元,用于通过网络接收数据搜索请求,其中要搜索的数据被保密,通过基于搜索请求的预定计算和存储在数据库中的数据的列表来搜索数据库,同时 涉及搜索请求的数据项保密,并产生对搜索请求的响应。

    • Cryptographic communication system including a sender terminal for encrypting and transmitting a message, a recipient terminal for receiving and decrypting the encrypted message, an agent terminal for decrypting the message in place of the recipient terminal, and a conversion server for supporting the agent terminal to decrypt the message. The sender terminal encrypts the message using a public key of the recipient terminal. Using a public key of the conversion server, a predetermined restricted condition, and a secret key for decryption of the message, the recipient terminal generates a delegation key allowing decryption of the message under the restricted condition and passes the delegation key to the agent terminal. The conversion server validates a power of the agent terminal to decrypt the message based on the information contained in the delegation key from the agent terminal. The agent terminal then decrypts the message with validation of the conversion server.
    • 包括用于加密和发送消息的发送方终端的加密通信系统,用于接收和解密加密消息的接收方终端,代替接收终端解密消息的代理终端,以及用于支持代理终端解密的转换服务器 消息。 发件人终端使用接收方终端的公开密钥对消息进行加密。 使用转换服务器的公开密钥,预定限制条件和解密消息的秘密密钥,接收方终端生成允许在限制条件下解密消息的委托密钥,并将委托密钥传递给代理终端。 转换服务器根据来自代理终端的委托密钥中包含的信息来验证代理终端的权力以解密该消息。 代理终端然后通过验证转换服务器对消息进行解密。

    • A vehicle notification sound emitting apparatus is basically provided with a sound emitting device and a notification sound control device. The sound emitting device emits a starting movement notification sound to outside of a vehicle to inform a person in an outside area surrounding the vehicle that the vehicle will transition from a stopped state to a moving state, and emits a moving notification sound to outside of the vehicle to inform a person in the outside area surrounding the vehicle that the vehicle is moving. The notification sound control device operates the sound emitting device to selectively emit the starting movement notification sound. The notification sound control device includes a notification sound emission timing section that sets a start timing of the starting movement notification sound in response to a shift operation having been performed and an additional start movement preparation operation of the vehicle having been performed.
    • 车辆通知声发射装置基本上设置有发声装置和通知声音控制装置。 声音发射装置向车辆外部发出开始移动通知声音,以通知车辆周围的外部区域的车辆将从停止状态转移到移动状态,并且向外部发出移动通知声音 车辆通知车辆周围的外部区域的车辆正在移动。 通知声音控制装置操作声音发射装置以选择性地发出开始移动通知声音。 通知声音控制装置包括通知声发射定时部,其响应于已经执行的换档操作和执行了车辆的附加的开始动作准备操作,来设定起动运动通知声的开始定时。
