A cell phone is disclosed for acquiring information to be transmitted to a receiving facility and for transmitting such thereto. A capture device captures information from an external source. A processor is provided for associating with the captured information a representation of the date and time of the capture of the information, such that the representation of the date and time information in association with the captured information forms augmented captured information. The processor also places the augmented captured information in association with subscriber information in a transmission of the augmented captured information to a receiving facility requiring such subscriber information. A transmitter transmits the transmission including the augmented captured information and the subscriber information to the receiving facility. An encryptor encrypts the augmented captured information with a symmetrical encryption algorithm to provide encrypted augmented captured information in the transmission with the subscriber information.

An encoding unit encodes at least a part of items of a CSV file including a plurality of records having a plurality of items with a unit of items of respective records. A creation unit creates an encrypted dictionary in which an encoded dictionary having been used for the encoding is encrypted with a unit of dictionary. A transmission unit sends, according to a request for a part of records included in the data, encoded data including the encoded part of records and the encrypted dictionary to a requesting source. A requesting unit requests a part of records included in the CSV file. A decryption unit decrypts the encoded data received according to the request by using the encrypted dictionary.

A printing apparatus includes: a printing apparatus storage unit that stores firmware to which a public key is added, the public key being information related to a public key encryption method; a printing apparatus network-communication unit that receives signature information obtained by encrypting a hash value of overwriting firmware with a private key corresponding to the public key, from the management server, and that receives the overwriting firmware from the file providing server; and a printing apparatus control unit that determines validity of the overwriting firmware by comparing a hash value generated by decrypting the signature information which is received from the management server with the public key stored in the printing apparatus storage unit, and a hash value of the overwriting firmware which is received from the file providing server.

In one example of the disclosure, an encrypted document and an encryption key for decrypting the encrypted document are received from a computer. Presence data for a printer is received via a first wireless network. A user instruction to print the encrypted document at the printer is received. A credential is received from the printer via the first wireless network, where the credential for communication with the printer via a second wireless network with greater bandwidth than the first wireless network. The encrypted document and the encryption key are sent to the printer, where the printer is to utilize the encryption key to decrypt the encrypted document and is to print the document following decryption.

Digital media can be automatically transferred between a digital capture device or storage device and one or more other devices with little or no user intervention. Media can be selected for automatic transfer based on one or more media-content or media-context characteristics.

An encryption circuit includes a fundamental vector generation circuit configured to generate a random number sequence for serving as a fundamental vector based on an initial vector, an image mask generation circuit configured to generate an image mask with a mask value set for each pixel in a region to be encrypted smaller than a frame size of the image, based on the fundamental vector and coordinate information for specifying the region to be encrypted, and an XOR operation circuit configured to compute an exclusive OR between each mask value of the image mask and each pixel value of the image data to generate encrypted image data.

Secure aircraft camera monitoring includes capturing images of an area of interest proximate to an aircraft, and securely transmitting the images as data files over an encrypted communication network associated with the aircraft. In one example, a system includes an image capture device configured to be secured to an aircraft to capture a plurality of images of a field of view of an area of interest proximate to the aircraft. The system also includes a processor configured to receive the plurality of captured images and convert the captured images to a plurality of data files. The system further includes a memory configured to store the data files, and a communication interface configured to connect to an encrypted communication network associated with the aircraft, wherein the communication interface is configured to securely transmit the data files over the encrypted communication network.

An information management control apparatus includes a storage unit, a transmission unit, and a permission unit. The storage unit stores a job including one of a pair of keys, with which both encryption and decryption are possible, and address information. The transmission unit encrypts a user ID of a login user by using the one of the keys and transmits the encrypted user ID through a communication unit in accordance with the address information, the user having been logged in in order to issue an instruction for executing the job. The permission unit permits execution of the job, in a case in which a user ID that has been encrypted by using the other of the keys and transmitted in response to the transmission is decrypted by using the one of the keys, if the user ID is the same as the user ID of the login user.

In an example, a method includes, at least one processor, in response to each of a plurality of requests, determining a halftone screen. Determining the halftone screen comprises encoding a signature pattern in the halftone screen, and halftone screens for different requests may be encoded with a different signature pattern. The halftone screen may be arranged such that, when applied to image data to provide a printed output, the pattern is discernible therein to provide a signature for the printed output.
