Detailed Description
The following provides a more detailed description of the present invention, with reference to the accompanying drawings.
The first embodiment is as follows:
referring to fig. 1, the integrated file-checking system based on block chain includes a file receiving module 10, a file storing module 20, a file storing module 40, a file inquiring module 50 and a file exporting module 60, wherein the file receiving module 10 receives a file scanning piece and file description information, the file description records file type, retrieval key value, uploading department, file establishing time and field information, the field information records field name and position of each field area 71 to be filled in by the file, as shown in fig. 2, the file storing module 20 extracts hash value of each field area 71 as field hash value, extracts hash value of the file scanning piece as file hash value, extracts hash value of all field hash values and file hash value together as certificate hash value, uploads the certificate hash value to a block chain 30 to obtain corresponding block height, and the file storing module 40 stores file scanning piece associated field hash value, The archive hash value, the certificate storage hash value and the block height are stored, the archive inquiry module 50 establishes an archive index, the archive index records an archive name, a type, a retrieval key value, archive establishment time and the certificate storage hash value, the archive inquiry module 50 receives an archive inquiry request, the archive inquiry request comprises an archive type and an inquiry key value, the archive inquiry module 50 verifies the authority of a requester, the authority passes verification and an archive scanning piece with the retrieval key value according with the inquiry key value exists, the archive name and the archive establishment time are fed back, if the inquiry requester chooses to export an archive, the target item is filled, the archive export module 60 adds the watermark of the target item typeface to the archive scanning piece, and then the archive scanning piece, the field hash value, the archive hash value and the certificate storage hash value are provided for the requester.
The file inquiry module 50 stores a file list required by each target item, the file inquiry module 50 receives a file inquiry request containing the target item and an inquiry key value, the file inquiry module 50 inquires whether a file with the retrieval key value according with the file type of each corresponding file list exists according to the file list required by the target item, if so, the file name and the file establishment time are fed back, and if not, no result is fed back. If the archive list required for handling the marriage registration comprises the account books, the identity cards and the prenuptial examination result lists of the two parties, if all three archives are sent to the archive receiving module 10, the names and the identity card numbers of the two parties are submitted through the marital registration window, the archive inquiring module 50 inquires the target items for marital registration, and the archives with the names and the identity card numbers meeting the submitted values can respectively inquire the account books, the identity cards and the prenuptial examination result lists of the two parties. The marriage registration window belongs to a civil service window set by the government, so that the marriage registration window has higher authority, the original value of all files can be checked, and the file export module 60 does not need to add an occlusion watermark.
The archive export module 60 stores the archive required by each target item and the required field name, when the requester selects to export the archive, the archive export module 60 adds the watermark of the target item typeface to the archive scanning element, and provides the archive scanning element, the field hash value, the archive hash value and the certificate-storing hash value to the requester after adding the shielding watermark to the unnecessary field position.
The file receiving module 10 also receives the biometric information of the person corresponding to the file, and when a requester without authority requests to inquire and export the file, the biometric information of the person corresponding to the file just acquired needs to be attached, and after the biometric information and the acquisition time stamp are verified by the file inquiring module 50, the authority verification is determined to be passed.
If the public transacts other items through the business subject, for example, transacting the membership card in the supermarket, the supermarket can shoot the face of the transactor on site, and then submit the transacted membership card items together with the acquired face information and name to the archive inquiry module 50. After the face is verified by the file query module 50, the identity card file corresponding to the name and the face is provided to the supermarket. Because the authority of the supermarket is low, when the file export module 60 exports the identity card file, the identity card number and the address are added with shielding watermarks, and all or part of shielding is carried out. After receiving the identity card file containing the blocking watermark, the supermarket verifies whether the hash values of the unoccluded name, gender and ethnicity, the photo and the like are consistent with those stored on the block chain 30. If the identity is matched, the transactor is judged to have local credible legal identity, so that the transactor is continuously transacted with the membership card. In the process, the supermarket can obtain the identification of the transactor, but cannot know the identity card number and the address of the transactor specifically. The system is convenient for the masses to handle various items and can protect the privacy of the masses.
The beneficial technical effects of this embodiment are: after the document scanning piece is stored by the block chain 30, the document scanning piece has a credible certificate, so that the paper piece does not need to be stored for a long time, and the cost of storing the paper document is avoided; the archives are convenient to look up by establishing the archive index, the archives can be shared among departments by means of the archive export module 60, the situation that the masses need to repeatedly provide the same certificate or data is avoided, and the masses can conveniently handle the archives.
Example two:
in the integrated file-checking system based on the block chain, in this embodiment, on the basis of the first embodiment, the file storage module 40 is specifically improved to reduce the storage space required for file storage and reduce the expenditure of storage hardware. In this embodiment, the archive storage module 40 periodically checks the number of archive scanning pieces in each archive type, when the number of archive scanning pieces in the same type reaches a preset threshold, the percentage of the repeated contents of the archive scanning pieces is determined, if the percentage of the repeated contents exceeds the preset threshold, a common template is established, the archive scanning pieces are represented as the superposition of the common template and the unique contents, the unique contents of the archive are stored in association with the common template identifier and the archive identifier, when the archive scanning pieces are called, the unique contents of the archive scanning pieces are read, the common template is read according to the common template identifier, the unique contents and the common template are superposed to restore the archive scanning pieces, and after the hash value of the archive scanning pieces is verified, the archive scanning pieces are provided to the archive export module 60.
Referring to fig. 3, when the common template of the file scanning component is established, the file storage module 40 executes the following steps: step A01) reading a preset number of file scanning pieces to form a sample set; step A02) counting the mean value of the file scanning piece in the sample set at each pixel; step A03) obtaining a common pixel set, wherein on the pixels in the common pixel set, the difference values of the pixel values and the pixel mean values of the file scanning pieces in the sample set are all lower than a preset threshold value; step A04), a blank file scanning piece is established, pixels recorded by a common pixel set are set as a pixel mean value, and a common template is formed; step A05) dividing the file scanning area into a plurality of rectangular areas 72, and numbering each rectangular area 72; step A06) calculating the difference value of the pixel values of the same position of the scanning piece and the common template in each rectangular area 72, and if the difference value is not 0 in the rectangular area 72, storing the serial number of the difference value-associated rectangular area 72; step a 07) the difference values of all rectangular areas 72 and the associated rectangular area 72 numbers constitute unique content.
Given a large number of paper application forms or qualification documents received by a window, the content is formatted with formatting terms, requiring only a small number of designated locations to be filled with basic information and signed. Thus, most of the pixel values in such scanning elements are the same, regardless of scanning device differences and light line differences. 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.
In this embodiment, the informed consent forms signed by the masses are scanned, hash values are extracted after scanning, the hash values are uploaded to the block chain 30 for storage, and then the paper pieces can be destroyed. The scanned document, which is certified by the blockchain 30, has legal effectiveness, thereby reducing the number of documents that need to be kept in paper real life. However, when the number of such scanning units is large, the storage space of the archive storage module 40 is large. In the embodiment, by establishing the common template, only the part of the area where the informed consent form is signed is stored separately as the unique content, and the rest part of the area is stored as the common template. When reading, the signature areas and the common templates which are stored separately are spliced, the hash value is extracted after splicing, the hash value extracted by the file which is spliced correctly is consistent with the hash value stored in the block chain 30, the authenticity of the file is proved, and therefore a large amount of storage space is saved.
When scanning paper files to obtain scanned parts, the problem that the pixel values of the same content area are not completely the same due to the change of scanning equipment or light conditions is solved. In this embodiment, when the file receiving module 10 receives the same type of file scanning element, the pixel value of the file scanning element is finely adjusted within the preset range, so that the number of pixels of the file scanning element that is the same as the common template is the largest, and after the confirmation of the scanner, the file receiving module 10 receives the adjusted file scanning element. The method for finely adjusting the pixel value of the scanning element within the preset range comprises the following steps: calculating a difference value of each pixel value of the scanning piece and the common template, and if the absolute value of the difference value is smaller than a preset threshold value, setting the corresponding pixel value to be the same as the common template; extracting the boundary of the scanning piece before adjustment and the boundary of the scanning piece after adjustment, wherein the boundaries are a set formed by pixels of which the difference values between pixel values and adjacent pixel values are larger than a preset threshold value; if the boundary is not changed, the adjustment is completed, and if the boundary is changed, the pixels near the changed boundary are restored to the pixel values before the adjustment, and then the adjustment is completed. When the adjustment value of the pixel is not large, but the adjustment is ingenious, a boundary can still be formed, so that lines or ink marks which can be observed are formed, and the authenticity of the document is influenced, therefore, the embodiment limits the occurrence of the boundary which exceeds a preset threshold value in the adjustment process. The space that this embodiment took through the compressed archive storage reduces the required equipment spending of storage archives.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit of the invention as set forth in the claims.
