The authenticity of the file is guaranteed by the file source department. The technology described in the embodiment can prevent the true archive from being tampered in the storage and transmission processes. By using the blockchain 20 to store the certificate, after the requester 50 obtains the scanned file of the file, it can be conveniently verified whether the scanned file received by the blockchain 20 is the same as the scanned file stored before. If so, the scan received by requester 50 is certified to be authentic. Therefore, when the file is shared, the authenticity can be guaranteed, and the file has a certificate handled as other matters.

Referring to fig. 2, the receiving subsystem 10 divides the scanned object into a plurality of regions 61, extracts hash values of the regions 61 respectively, and records the hash values as the hash values of the regions 61, the hash values of all the regions 61 form a region hash value set 62, the region hash value set 62 extracts the hash values again as a certificate hash value 63, the file index directory records the region hash value set 62 and the storage location of each region 61, the storage subsystem 30 stores the plurality of regions 61 in a distributed manner, the intelligent sharing subsystem 40 reads all the regions 61 of the scanned object according to the file index directory, and the regions 61 are spliced and restored to the scanned object. The excessive scattered storage of the scanning pieces can improve the storage safety of the scanning pieces, even if the stored data is partially leaked, the whole content of a specific file cannot be leaked, only a partial area 61 in the file can be leaked, and the storage safety is higher.

When the receiving subsystem 10 divides the scanned object, the dividing positions of the scanned object of the same file type are the same, the storage subsystem 30 reads a plurality of regions 61 of the same file type and the same position, calculates the pixel value mean value of the plurality of regions 61 at each pixel position, the pixel mean value is taken at all the pixel positions to form a region template 64, referring to fig. 3, the pixel value difference value of each pixel position of the region 61 of the scanned object and the corresponding region template 64 is calculated, the pixel value difference value is expressed by using the preset byte length, a difference value image 65 is obtained, an exception set 66 is established to record exception pixel points of which the pixel difference value exceeds the preset byte length expression numerical range, the exception set 66 records the pixel coordinate and the pixel value of the exception pixel point, when the region 61 is read by the intelligent sharing subsystem 40, the difference value image 65 is overlapped with the region template 64, and then the corresponding pixel position is replaced by the exception pixel point to obtain the restored region 61, the region 61 is spliced to obtain a restored scan.

A large number of paper application forms or qualification certification documents generated by the basic level civil office organization have formatted terms, and only a small number of designated positions are required to be filled with basic information and signed. For example, all kinds of informed consent forms, the recorded contents are the same, and the people are required to sign at the end. Such informed consent forms are important documents when the responsibility for disputes is confirmed afterwards, and can be destroyed only after a preset time period is saved. Therefore, most of the pixel values in such a scanning element are the same regardless of the scanning device differences and the light ray differences.

The scanning element is stored in a picture format, the pixels of the picture are represented by an RGB color system, each pixel uses 3 channels, the channel value of each channel is represented by 1 byte, namely the value range of each channel is [0,255], the pixel value is formed by the collection of three channel values, and each pixel value occupies 3 bytes. Due to the large number of scans of the same type of document, the images in the same area 61 are highly similar. The difference between the pixel value of each scan element at the same pixel location and the common slice will be small. It is sufficient to use half a byte for representation. I.e. the range of the difference value of each channel is 0,15 plus one bit to indicate the sign of the difference value. The difference image 65 in fig. 3 is lighter in color because the image of the region is not much different from the region template 64 compared to the region template 64. The difference is mainly formed due to the hardware differences of the scanning device at each scan. The difference caused by the file placement position is not discussed in this embodiment, and the cutting alignment should be performed by using a conventional technique, or a scanning device with an alignment function is used. If the conventional technology is adopted to carry out white balance on the scanning piece, better technical effects can be obtained. For pixels with differences exceeding 0,15, such pixels are recorded separately by means of the exception set 66. Because the shared slice only needs to be stored once, most pixels can be stored by using pixel difference values, and the occupied space of each pixel is shortened by half. Although a small number of pixels need to occupy the space of the exception set 66, the number of exception pixels should be small for the same region 61 of the same type of archive, thereby occupying less storage space as a whole. The scheme provided by the present embodiment reduces the storage space occupied by the slice region 61 by sharing the slice, pixel difference, and exception set 66. After the paper file is scanned, fine adjustment is carried out on the scanning piece within a preset pixel value change range, so that the pixel difference value between the area 61 and the area template 64 is minimum. The number of exceptional pixels recorded in the exception set 66 can be reduced after the fine adjustment, and the storage space occupied by the exception set 66 can be reduced.

The intelligent sharing subsystem 40 receives a file information verification request, the file information verification request comprises a plurality of inquiry key values and a plurality of field values, after the intelligent sharing subsystem 40 verifies the authority level of a requester 50 sending the file information verification request, the file index directory is inquired, if a scanning piece which is in accordance with the inquiry key values exists, an image recognition program is operated to recognize recorded contents in a position of a corresponding field area 67 of the scanning piece, whether the contents recognized by the image are matched with the plurality of field values contained in the file information verification request or not is judged, if the contents are matched, the corresponding field values are fed back to be verified to be passed, if the contents are not matched, the corresponding field values are fed back to be not verified to be passed, if the contents are not recognized, the corresponding field verification is fed back to be failed, and the corresponding slice area 61 is provided for the requester 50.

When the masses transact in other departments or organizations, the related information is provided, and the transacting departments or organizations submit the information filled by the masses to the intelligent sharing subsystem 40 for file information verification. If the verification is passed, the user can do the work according to the information filled by the people. The scanning piece does not need to be restored any more, and the scanning piece does not need to be transmitted on the network, so that the privacy and the safety of the archive can be more effectively protected.

The beneficial technical effects of this embodiment are: the scanned part has the authenticity certificate through the block chain 20 certificate storage, and the scanned part has the certificate efficacy technically and can be used as the basis for registration or transaction of other files, so that a file management organization does not need to store paper files any more, and the file storage cost is reduced; the electronic scanning piece can be more conveniently searched, transmitted and shared, so that the files can be used for more purposes, and the value of the files is exerted.

The second embodiment:

the embodiment provides a new improvement scheme for storage of scanning parts on the basis of the first embodiment. Referring to fig. 4, in this embodiment, after the region 61 is trimmed, if the pixel difference between the pixels of the region 61 and the region template 64 is smaller than the preset threshold and the exception pixel points recorded in the exception set 66 are not consecutive, the region 61 is modified to be the same as the region template 64, the hash value of the target of the region 61 is extracted as the hash value of the region 61 and is included in the region hash value set 62, the storage module does not store the region 61, the corresponding region 61 is not stored in the file index directory, when the wisdom sharing subsystem 40 restores the scanned object, if the storage location of the region 61 is read, the mark that the region 61 is not stored is read, and the corresponding region template 64 is used for restoring the scanned object. If the exceptional pixel points are discontinuous, the exceptional pixel points do not record any useful information and are noise points caused by scanning conditions.

Manually setting the splitting position of each file type, enabling the area 61 to at most comprise a field area 67, enabling the field area 67 to be the area 61 where the value of the file field is located, associating the field area 61 comprising the field area 67 with a corresponding field name, extracting the hash value of each area 61, incorporating the hash value into the area hash value set 62, establishing a field list required by transaction records by the intelligent sharing subsystem 40, enabling the file query request to comprise the transaction, obtaining the fields which are not required by the transaction according to the transaction table when the intelligent sharing subsystem 40 recovers the scanned part, generating the fields which are not required by the coverage of the coverage color 68, referring to the attached figure 5, providing the scanned part with the coverage color 68, the area hash value set 62, the certificate-storing hash value 63 and the block height to the requester 50, and verifying the certificate-storing hash value 63 after the requester 50 verifies the hash value of the area 61 which is not covered by the area 61, and if the verification is passed, judging that the received scanning piece is authentic and credible.

As shown in table 2, the created transaction table of the present embodiment records the field name and the file type required for each transaction. For a given field name, there may be multiple archive types that are recorded, and the key or may be used to link multiple archive types in the transaction table. The field name 7 as noted in the table can be found in both the type four and type five archive types. When transaction 1 is processed, the file which is in accordance with the retrieval key value is found from the file types of type one and type two, and the values corresponding to field name 1, field name 2 and field name 3 are obtained. The smart sharing sub-system 40 generates a masking color 68 to mask the slice region 61 other than the slice region 61 corresponding to the field name 1, the field name 2, and the field name 3, and provides the generated masking color to the requester 50. Other information in the profile can be hidden from requestor 50. Namely, the transaction of item 1 is not affected, and the range of the file information diffusion is controlled.

The embodiment uses an improved storage mode of the file scanning piece, reduces the storage space occupied by the scanning piece, and further saves the cost of file storage. The field name of the field area 67 included in each slice area 61 is manually noted. The wisdom sharing subsystem 40 selects the corresponding slice region 61 to provide to the requester 50 according to the fields required by the requester 50 to handle the transaction, and the rest of the slice regions 61 are covered by the covering color 68, thereby effectively controlling the diffusion range of the file privacy.
