A method for picture-based barcode encoding and decoding is provided herein. The method for picture-based barcode encoding includes: transforming an original data into an original data bitstream; performing an error correction on the original data bitstream for translating the original data bitstream into an error corrected bitstream; selecting all or part of the picture as an encoded area; calculating a data storage capacity of the encoded area; adjusting a size of the error corrected bitstream or a size of the encoded area for equalizing a data storage capacity of an encoded data bitstream and the data storage capacity of the encoded area; and adjusting a pixel value of the encoded area according to the encoded data bitstream.

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 imaging system may output embedded data in an output frame. Selected bits of pixel data words, corresponding to data read out from imaging pixels and non-imaging pixels, may be modified to correspond to bits of embedded data. Modifying pixel data words may include receiving a pixel data word and decatenating the pixel data words into fragments of the data word. A first fragment may correspond to bits of the data word that are replaced by embedded data bits output from an embedded data engine. A second fragment may be modified using arithmetic circuitry based on whether the embedded data bits that replace the first fragment are the same as bits of the first fragment. An output data word may be produced that includes embedded data bits at its least significant bits, most significant bits, or intermediate bits.

A system and method provide an image data file encoding said image in accordance with a standard image format and a page of content in a markup language, said page of content being intended for transmission over a telecommunications network from a server to a client for display by a browser running on the client, said page of content including a link or reference to the image data file for incorporating the image within the page of content. The image is converted from said standard image format into a format in which the image is encoded using said markup language, and the image encoded using said markup language is incorporated into the page of content to replace said link or reference to the image data file prior to transmission of the page of content.

A communication system includes a server device and a client device. The server device includes an encoding unit that encodes information about characters contained in a first image to generate an encoded image, a generation unit that generates a second image in which the generated encoded image is embedded at a position specified from a position of the characters on the first image in place of the characters, and a transmission unit that transmits the second image to the client device in response to a request for the first image from the client device. The client device includes an extraction unit that extracts the encoded image from the received second image, a decoding unit that decodes the extracted encoded image, and a replacement unit that replaces the encoded image on the second image with characters specified from decoded information to generate the first image.

In an image forming apparatus, a compression history recording portion stores compression history information in a non-transitory computer-readable information storage medium, wherein the compression history information represents results of accumulation of compression levels through the compression process executed by the data compression portion. A history monitoring portion executes a predetermined improvement process when the compression history information satisfies a predetermined insufficient compression condition.
