Abstract: An information processing device (1) includes a signal receiver (12), an entry information inputter (16), a storage (11), and a document information generator (15). The signal receiver (12) receives a signal representing a transfer request to transfer data. The entry information inputter (16) inputs entry information that is information to be entered into a transfer procedure document that is a document for a transfer procedure with respect to the transfer request. The storage (11) stores the entry information inputted by the entry information inputter (16).

Abstract: To provide a centralized control system for defending and taking countermeasures against an illegal access. A network device 3 detects an illegal access packet P1 transmitted from an illegal accessor's terminal 6, and transfers an encapsulated packet P2 of the illegal access packet P1 to a data center 1. A control system 11 in the data center 1 analyzes the packet P2, encapsulates a response packet P4 from a decoy server 13 pretending to be a response from a target server to be attacked 5 to acquire a packet P3, and then transmits the packet P3 to the network device 3. The network device 3 decapsulates the packet P3 so as to extract a response packet P4, and transmits the response packet P4 to the illegal accessor's terminal 6. The illegal accessor's terminal 6, upon reception of the response packet P4, would believe that the response packet P4 should be transmitted from the server 5, and start to illegally access the decoy server 13.

Abstract: Video/audio data is stored in an HDD (115) and information concerning to the video/audio data is also generated and stored with the video/audio data. A comparison unit (112) compares the video/audio data with feature data stored in a selector unit (111) and detects a position where the feature data is contained. When the feature data is detected, a tag information generation unit (113) generates tag information and stores the tag information after adding thereto the video/audio data.

Abstract: A cryptographic apparatus has an encryption/encapsulation processing section for encrypting plaintext data received from a plaintext network, referencing the predetermined correspondence between addresses and different cryptographic apparatus, setting a new header based on the cryptographic apparatus corresponding to the address set in the header of the plaintext data as encapsulation processing, and transmitting ciphertext data provided thereby to the ciphertext network of the same IP subnet as the plaintext network, and a decryption/decapsulation processing section for decrypting ciphertext data received from the ciphertext network into plaintext data, again setting a header based on the address set in the header of the plaintext data as decapsulation processing, and transmitting plaintext data provided thereby to the plaintext network of the same IP subnet as the ciphertext network.

Abstract: A cryptographic communication system in which packet data between terminals is encrypted, and which can reduce the wait time in a decryption apparatus. In the cryptographic communication system in which packet data transmitted and received between terminals is encrypted by a transmitting-side cryptographic apparatus and is decrypted by a receiving-side decryption apparatus.

Abstract: In an encryption communication system, an encrypt key ID of an encrypt apparatus appearing on a communication path between terminals is acquired by using a key seek packet, and an encrypt key ID is automatically learned based upon a key seek response packet for notifying the acquired encrypt key ID. As a result, communication data between the terminals are encrypted/decrypted, transparently relayed, and discarded by the respective encrypt apparatuses. Even when a communication network is made large and complex, the network for the encrypt communication can be readily managed.
