Description of the new type: [Technical field to which the new type belongs] This new type relates to an image capture device, especially an image capture signature device. [Previous technology] Due to the rapid development of network communication, real-life document data, whether text, sound, image, or other information, can be replaced with bit-type data, which can be quickly transmitted through the information network. — Generally, in order to ensure that information is not vulnerable to tampering or illegal access during transmission, the commonly used method is to sign a digital signature. Common digital signature methods include RSA and DSA (Digital signature

You must first convert the analog data into digitized data through digitization. Only digital signatures can be generated by signing the information. For data such as traditional photographs, negatives, etc., they are stored in a digital slot after knowing the field machine. After signing this case, the 7G image of the image can be determined. 11 does not guarantee that the image will be digitized and signed. Whether the image has been tampered with during the process. "For example," the health insurance information that you see in the catalogue. If the medical institution uses, for example, X-ray film as the basis for the payment, how to save 4 ^ shixiang inch will undoubtedly constitute a major difficulty for health insurance institutions. Medical institutions can save all the negative 5 M275469 numbers, and worry that the bad medical institutions will falsify the data and make false declarations. How to solve this dilemma and provide reliable answers has become a topic of concern in the industry. [New type Content] Therefore, the purpose of this new model is to provide a device that converts data into a digitized format and ensures its authenticity, distress, and purity.

The device includes an image capture device, a control device, and a digital signature. The control device is used to control the image capturing device to convert the original data into a digital data stream, and the digital signature generating device generates a digital signature corresponding to the digital data stream. [Embodiment] 'The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings. Referring to FIG. 1, a preferred embodiment of the novel image manipulation and signature device is applicable to an original data, the original data may be a message of text, image, or image 2 includes an image manipulation device], a control device 2 A first storage 3, a digital signature generating device 4 and a second storage unit 5. = Remove device!

The result is a digital signature. After removal ', the control device 2 outputs a digital signature and a digital data stream. Special attention to the hash function 4] has the characteristic of one-way irreversible operation. Only the digital digest can be used to derive the message digest, but the digital data cannot be inferred from the message digest. The second storage unit 5 is used to receive and store digital signatures and digital data streams, and the storage form may be digital «formatted digits" such as PKCS # 7 or XML signatures. In this embodiment, the second storage unit $ Can be magnetic memory 'is not limited to this. It should be noted that the digital signature and the M275469 digital data stream can also be streamed separately.

The receiver then proceeds to step 62, and uses the control 1 to convert the original data 12 to the dagger image capture device τ / 10 into a digital data stream, which is described as a digital slot, but not limited to this. The tender plate thins the negative film and then proceeds to step 63 to sign the digital data converted from the two strong classes of Yingde and Liujian in the first deposit. The early sign 3 is used by the digital signature generation device 4 to calculate the number ^ Go to step 64, the digital sign generation farm 4 receives the digital tribute stream stored in the 'sub-unit 3', and applies a digital signature to the digital data stream. ^ Finally, step 65 is performed to output and store the digital data stream and digital signature in the second storage unit 5. In summary, using this new type of image capture and signature equipment, in addition to confirming and identifying the identity of the signer of the data and the integrity of the identification data, it is better for non-digitized data such as medical images Data, to ensure that during the digitization process, the data will not be tampered with, and even if the data is tampered with in the future, it can still be detected by means of digital signatures. However, the above are only the preferred embodiments of the new model, and the scope of the implementation of the new model cannot be limited by this, that is, the simple equivalent changes and modifications made according to the scope of the new model application patent M275469 and the description of the new model. , Are still covered by the new patent.
