    Abstract: When an original image containing a code image is lossy-compressed, the image quality of the code image is deteriorated. Thus, due to the deterioration of the image quality of the code image, information contained in the code image cannot be acquired. Thus, a portion corresponding to the code image is not lossy compressed, and the portion corresponding to the code image, which has not been subjected to lossy compression, is stored in a storage unit.

    Abstract translation: 当包含代码图像的原始图像被有损压缩时,代码图像的图像质量恶化。 因此,由于代码图像的图像质量的恶化,不能获得代码图像中包含的信息。 因此,对应于代码图像的部分不被有损压缩,并且与没有进行有损压缩的代码图像相对应的部分被存储在存储单元中。

    Abstract: Apparatus, systems and methods for authenticating images by digitally signing hidden messages near to the time of image capture are disclosed. In one implementation, a system includes an image data source and processing logic responsive to the image data source. The processing logic being capable of quantizing transformed image data blocks to generate encoded image data blocks and embedding a message within one or more of the encoded image data blocks by modulating one or more zero valued frequency coefficients. The processing logic may also be capable of generating metadata specifying at least the one or more zero valued frequency coefficients modulated to embed the message.

    Abstract: A variable c1 is counted up by one for the Nth bit in attribute information=“1”, and a variable c0 is counted up by one for the Nth bit=“0” (S402). When the total code amount of the coding results of pieces of attribute information which have been coded up to now has exceeded a predetermined threshold, a value held by the variable c0 at this time and that held by the variable c1 are compared with each other to determine which of “1” or “0” is set for the Nth bit of subsequently input attribute information (S405).

    Abstract translation: 对于属性信息=“1”中的第N位,变量c1被递增1,并且对于第N位=“0”,变量c0向上计数1(S402)。 当迄今已经编码的属性信息的编码结果的总代码量已经超过预定阈值时,将此时变量c0所保持的值和由变量c1保持的值彼此进行比较,以 确定对于随后输入的属性信息的第N位设置“1”或“0”中的哪一个(S405)。

    Abstract: Forensic communication apparatus and method. An apparatus is disclosed for recording image or other data in real time. The apparatus includes a capture device for capturing the image or other information. Once captured, a local verification device is operable to indelibly mark the captured image or other information with the date, time, location and information identifying the creator of the data. A transmitter is provided for transmitting the locally verified captured image or other information in real time to a secure storage facility. The capture device is operable, after the locally verified captured image or other information is transmitted to the secure storage facility, to receive and verify acknowledgment of the receipt of the transmitted locally verified captured image or other information to the storage facility.

    Abstract: An electronic-mail reception apparatus has a body and includes a facsimile receiver that negotiates with a sender before receiving image data, to receive image data in facsimile format from the sender via a telephone network. An electronic-mail receiver receives image data in an electronic mail format and character code data in the electronic mail format from a mail sender via a communication network. A converter converts the image data in the electronic mail format into image data in the facsimile format, a font section converts the character code data received by the electronic-mail receiver into image data, and an output section outputs the image data converted by the converter and the image data converted by the font section. The facsimile receiver, the electronic-mail receiver, the converter, the font section and the output section are integrated in the body of the apparatus.
