Abstract
The present invention discloses a paper printed file secrecy method. The method is characterized in that client software is installed in a computer of a sending party and a computer of a receiving party, and the software is bound by using a hook technology and uses all related printing services of the computer; the client software has a symmetrical encryption function, and algorithms include a recombination method, replacement, arrangement or confusion; when a printing request is sent, the client software automatically intercepts and replaces to-be-printed original content with a meaningless file in which all words are in a chaotic order and prints the meaningless file; and when the encrypted paper arrives at a receiver, the receiver scans the encrypted paper with a scanner controlled by the client software, rearranges the words in a correct combination sequence by using a secret key and an algorithm the same as that of the sending party and then prints the content again at once, so that the printed content is correct plaintext. According to the paper printed file secrecy method, the secrecy method is provided for the file body, so that the security of the file body in transmission is improved.
Description
Technical field
The present invention relates to a kind of papery mimeograph documents time slot scrambling.
Background technology
Along with the development of protecting information safety means, the salvo of e-file is also more and more rich and varied, the information-leakage of electronic form has obtained very big containment. But for the means of defence that this information carrier of paper document has not but had, paper document is still in transmitting procedure and is very easy to divulge a secret, the aspects such as traditional preventive means is in transportation, file closing take means.
Summary of the invention
The present invention is to solve the deficiencies in the prior art, it is provided that a kind of papery mimeograph documents time slot scrambling, for a kind of method that file body provides secrecy.
For solving above-mentioned technical problem, a kind of papery mimeograph documents time slot scrambling provided by the invention, adopt the following technical scheme that
A kind of papery mimeograph documents time slot scrambling, it is characterised in that comprise the steps:
S1: client software all installed by sender's computer and recipient's computer, this software uses Hook Technique binding to use all print of computer;
S2: client software has symmetric cryptography function, algorithm is recombination method or displacement, arranges, obscures;
S3: being recombinated according to the key randomly generated out by the word on file, the order of word is disturbed completely;
S4: when sender carries out print request, as printed at word midpoint, client software can automatically be intercepted and captured and the content originally printed is replaced as the completely chaotic meaningless document of word sequence and print;
S5: this encryption paper has arrived recipient place, recipient locates to use this paper of scanner scanning, scanner is also affected by client software and is controlled, client software immediately passes through OCR OCR and the image information on paper is converted to and can edit Word message after reading paper scanning information, and using the key identical with sender and algorithm again to print at once after these words are rearranged for correct built-up sequence, the content printed specifically is correct cleartext information.
Specifically, privacy procedure include encrypted print to read again arrive deciphering printing.
Specifically, described plaintext paper is by obtaining the scanning of ciphertext paper, information processing, deciphering, again printing.
Specifically, described AES and key include but not limited to institute's extracting method in literary composition.
A kind of papery mimeograph documents time slot scrambling provided by the invention, for a kind of method that file body provides secrecy, improves the safety in transmitting procedure of the file body.
Accompanying drawing explanation
Fig. 1 is the step schematic diagram of a kind of papery mimeograph documents time slot scrambling described in the embodiment of the present invention.
Detailed description of the invention
The papery mimeograph documents time slot scrambling embodiment of the present invention being supplied to below in conjunction with accompanying drawing is described in detail.
As it is shown in figure 1, a kind of papery mimeograph documents time slot scrambling that the embodiment of the present invention provides, it is characterised in that comprise the steps:
S1: client software all installed by sender's computer and recipient's computer, this software uses Hook Technique binding to use all print of computer;
S2: client software has symmetric cryptography function, algorithm is recombination method or displacement, arranges, obscures;
S3: being recombinated according to the key randomly generated out by the word on file, the order of word is disturbed completely;
S4: when sender carries out print request, as printed at word midpoint, client software can automatically be intercepted and captured and the content originally printed is replaced as the completely chaotic meaningless document of word sequence and print;
S5: this encryption paper has arrived recipient place, recipient locates to use this paper of scanner scanning, scanner is also affected by client software and is controlled, client software immediately passes through OCR OCR and the image information on paper is converted to and can edit Word message after reading paper scanning information, and using the key identical with sender and algorithm again to print at once after these words are rearranged for correct built-up sequence, the content printed specifically is correct cleartext information.
Specifically, privacy procedure include encrypted print to read again arrive deciphering printing.
Specifically, described plaintext paper is by obtaining the scanning of ciphertext paper, information processing, deciphering, again printing.
Specifically, described AES and key include but not limited to institute's extracting method in literary composition.
A kind of papery mimeograph documents time slot scrambling provided by the invention, for a kind of method that file body provides secrecy, improves the safety in transmitting procedure of the file body.
The above; being only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope that the invention discloses; change can be readily occurred in or replace, all should be encompassed within protection scope of the present invention. Therefore, protection scope of the present invention should described be as the criterion with scope of the claims.
