In an information processing apparatus which can encrypt a file and can store the encrypted file at a predetermined location, an input file is separated into a header field and data field, and the separated data field is encrypted and saved in association with information included in the header field. In the meantime, a keyword required to specify the file is extracted from the separated data field, and the extracted keyword is converted into a hash value. The obtained hash value is stored in association with the information included in the header field. Upon storing a file, the contents of the file after storage can be prevented from being easily recognized by a third party.

There is disclosed an apparatus for searching a device on a network. A device search client links a search condition for searching the device with an icon to store the search condition. When a user designates the icon, the search condition linked with the icon and stored is inquired of a device search server to obtain the search result. Subsequently, the display form of the designated icon corresponding to the search condition is changed based on the obtained search result.

Device search apparatus

According to the present invention, a search condition can be moderated to easily understand a desired device without performing re-search, even if there is no device completely matching the search condition. An attribute of an object class is extracted out of the search condition designated by an operator to search a device meeting the attribute. A matching state of each attribute of the search condition first designated by the operator for a result obtained from the above search is visibly displayed.

Device search system

The present invention provides an apparatus for searching a device on a network. The device searching server acquires a search condition from the device searching client, searches a device on the network and returns the search result to the device searching client. If the number of the device matching the search condition is at least equal to a predetermined number, additional information such as location information and charge information is added to the search result. Also if the device matching the search condition is absent, a device of a high frequency of use, determined on the use history, is outputted as the search result.

Device searching apparatus

Each network device connected to a network broadcasts a cold start trap when activated. A monitoring device captures this trap and checks whether the trap is an SNMP packet. If the trap is an SNMP packet, the monitoring device extracts the address from the received packet and registers the address in a directory server, or requests the status of a device as a transmission source and registers the received status in the directory server.

Network device managing apparatus and method

Conventionally, crowded network traffic occurs because duplicated data exchange is performed between network management software and network devices. A network-device management method according to the present invention includes a search step of searching a device connected to a network, an acquisition step of acquiring a value of a device attribute relating to the device detected in the search in the search step, and a storage step of storing values of a plurality of device attributes relating to the device detected in the search in a storage device. If the value of each of the plurality of device attributes relating to the device detected in the search is stored in the storage device, the value stored in the storage device is used. It is thereby possible to prevent crowded network traffic by transmitting and receiving only necessary packets in a network-device search sequence.
