  • Patent number: 7676060
    Abstract: A method of identifying content in a distributed computing system. The method receives an image or audio signal in a first device in the distributed computing system, such as a cell phone or other wireless device. In this device, the method performs an analysis of characteristics of the signal to identify portions of the signal from which to derive a content identifier. The method then sends the portions to a second, remote device in the distributed computing system, such as a server. The server further processes the portions to derive a content identifier, which in turn, is used to look up data corresponding to the content, such as a Uniform Resource Locator. In the case of a wireless telephone network, for example, the method distributes the task of identifying content signals captured through the microphone or camera on the phones in the network.

    Abstract: An image forming system which is capable of enhancing security in an i-copy function. A server apparatus stores document data once having been printed in association with a sheet identifier recorded on a print sheet on which the document data has been printed. An image reader section reads the sheet identifier from the print sheet when a copy command is issued by the user authenticated based on an entered user identifier by a CPU of a MFP. A printer section reads out and prints the document data from the server apparatus. When the sheet identifier has not been read from the print sheet based on the copy command over a predetermined time period, the document data is inhibited from being printed by the printer section.

  • Patent number: 7552324
    Abstract: A printer generates a public key with a passphrase containing at least printer position information and a random number by a public key cryptography, and holds this random number. A print client previously acquires the public key from the printer. When transmitting print data to the printer, the print client encrypts the print data in advance with the acquired public key and transmits the encrypted print data as print transmitting data. The printer which has received the print transmitting data generates a private key with a passphrase containing at least printer position information and the held random number by the public key cryptography. The printer then decrypts the received print transmitting data with the private key. Consequently, the security of the print data transmitted from the print client to the printer via a network is ensured.

  • Patent number: 7467300
    Abstract: Coded data for disposal on or in a surface that includes a number of coded data portions. Each coded data portion encodes an identity of an object or the like associated with the surface. In addition, each coded data portion encodes at least part of a data object so that the data object is encoded in its entirety over a number of data portions, thereby allowing the data object to be reconstructed. The data object can include digital data relating to the object, such as product information, or a digital signature of at least part of the identity.

  • Patent number: 7447908
    Abstract: A method of using a mobile device to authenticate a print medium offline before completing printing onto the print medium, the mobile device including processing means, a printhead and a sensor, the print medium comprising a laminar substrate, the method comprising the steps of: using the sensor to sense coded data provided on a surface of the substrate; using the processing means: determining, from the sensed coded data: an identity of the print medium; and at least part of a signature, the signature being a digital signature of at least part of the identity; determining, using the at least part of the signature, a determined signature; generating, using the determined signature and a public key stored in the mobile device, a generated identity; comparing the identity to the generated identity; and authenticating the print medium using the results of the comparison; and in the event the authentication step is successful, using the printhead to print onto the print medium.

    Abstract: An image forming apparatus is supplied capable of preventing data stored in a non-volatility memory from being read out when the non-volatility memory is stolen. In the image forming apparatus, an encryption function section of encryption/decryption function section encrypts print job received from an information processing apparatus or print data made in the image forming apparatus, and stores it to a non-volatility memory; and a decryption function section of the encryption/decryption function section decrypts the print job or the print data encrypted by the encryption function section and stored in the non-volatility memory, and outputs it.

  • Patent number: 7436956
    Abstract: Encryption of documents is used to restrict access to such documents to those users who have the appropriate decryption keys. The encryption of documents on public web servers hitherto has prevented indexing by search engines. By keeping words and possible sentences or paragraphs intact in the encrypted document but re-ordering elements of the document to prevent the document being human-readable, the possibility of encrypted documents being indexed by search engines is provided.

  • Patent number: 7430762
    Abstract: Identification card manufacturing security restricts use of an identification card manufacturing system with only authorized supplies. In accordance with one aspect of the invention, a supply-specific security code (SSSC) and supply-specific data are stored in memory of the supply. The SSSC is translated using the supply-specific data. Finally, the supply is authorized for use with the identification card manufacturing system only when the translated SSSC is found to be valid. In accordance with another aspect of the invention, an identification card manufacturing system is configured to operate only with supplies having corresponding customer-specific security codes (CSSC). A supply CSSC and supply-specific data are retrieved from memory of the supply. Additionally, a system CSSC and system-specific data are retrieved from memory of the identification card manufacturing system. The supply CSSC and the system CSSC are translated using the supply-specific data and the system-specific data, respectively.

  • Patent number: 7398545
    Abstract: A user data management device, a storage medium which stores a control program, and a control method are disclosed which efficiently report the identity of a user who is using equipment to some or all members of the department in which that equipment is located, or to managers of that department, in order to be informed of the use status of that equipment, and control the use of that equipment by unauthorized users. The user data management device includes input means that inputs user data belonging to a user that will use the equipment, notification means that will provide one or more persons with identity data concerning a user who is using the equipment in which the user data was input, authentication means that authenticates the user from the user data, and notification determination means that will determine one or more persons to be provided with identity data, and then provide identity data to them that identifies the user authenticated with the authentication means by means of the notification means.

  • Publication number: 20080159530
    Abstract: The invention introduces a stand-alone small electronic device that provides the means for computer users to encrypt and keep their everyday confidential account login information in an indexed notebook or stored in a removable memory module for easy reference. Such account information includes User-Names, passwords, secret questions, and secret answers to those questions. This eliminates the risk of confidential account information exposure, should the storage media gets lost, stolen, or misplaced. Account login information are entered as separate character-strings into the device and are encrypted by using software that makes use of a “Master Password” phrase/character-string as an “Encryption-Decryption-Key”. The Master Password is a phrase or a combination of words, characters, and numbers a user can easily remember. Unlike a personal computer that is attached to networks, the stand-alone device is not connected to a network or the internet in a way to jeopardize user account information confidentiality.
