TW402713B - A delivering system for classified documents with ownership - Google Patents

Abstract

A delivering system is used to deliver unsent documents between senders and receivers. We usually need two public notary organizations, one is fair gold key preservation center; and the other is fair storage apparatus. Fair gold key preservation center is responsible for saving gold key with ownership of senders and fair storage apparatus is responsible for publishing those corresponding examined info of certificated documents for receivers to conveniently proceed checking process.It should be at the same time that we have to issue examined info and comments/signature related info as well to fair storage apparatus as senders deliver their own documents. Fair storage apparatus will redeliver comments/signature related info back to the fair gold key preservation center to conveniently examine comments/signature related info according to those saved gold key with ownership of senders. If the certification is correct, fair storage apparatus will publish the examined info for the senders to audit.

Description

402713 ------- V. Description of the invention (ί) The present invention relates to a method for transferring files electronically, in particular a method for transferring files with a protection mechanism for proof of title, which can be digitally signed and stamped. (Digital signatUfe) In the case of forgery and destruction, the purpose of file transfer confirmation can still be achieved. In the process of electronic file transmission, in order to achieve the purpose of document source certification and to ensure the integrity of the document, several chapters are the most common type of protection mechanism. There are many ways to implement digital signatures. The more common ones include RSA, DSA, and E1G bribery. —General digital signatures use asymmetric gold records, that is, the private signature balance used for signature actions and the public verification key used for verification actions. The issuer ’s private signature key is kept by itself. When a piece of money is produced for a certain document, the receipt is convenient and transparent. ^ A public verification key that can be obtained to verify whether the digital signature is indeed issued by the author.

At this time, the receiver B can use public inquiry. Check it out (such as 16 in Figure 2 and 161 in Figure 3) to confirm that it is a legal document. Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economics Fig. 3 shows a network transmission flowchart of a file transmission method according to the first embodiment of the present invention. As shown in the figure, when the sender A wants to send the first document to the receiver b, the sender must first send its proof of ownership verification key to TKc (m). Then, the sender A will send the document to the recipient and send the corresponding audit information and signature information to TSA (I21). ETSA will send the signature information to tkc for verification (141), and TKC will send the verification The result is returned to TSA (I51). If the verification result is correct, the TSA will release the audit information corresponding to this document ’after the confirmation by the recipient B (161) Second, as for the other documents, it will be processed according to the same procedure. In this way, the author can use the audit information announced by the TSA to renew the recognition that the document was issued by the author, and the author can also use digital early signing technology to ensure that only the recipient can correctly extract the data, so it can Ensure the legality of both parties in file transfer.

Description of invention (

Then further use the technology of asset collection to further protect the portion of the proof of ownership from issue A 2 to recipient B, thereby strengthening the fortune. Information hiding technology has become a hot topic in recent years, and it has its own necessity in terms of data security and copyright protection. Information hiding technology is slightly different in concept from traditional data confidentiality technology, and hides the information that needs to be kept secret (secret information) in other information (virtual information, etc.) and only allows users who have the right to make secret information available. By extracting this secret information, other people can only see the contents of the virtual information. Printed by the Ministry of Economic Affairs

In this embodiment, the information hiding technology is mainly used on the transfer wheel where the sender A sends the document itself and its ownership certificate to the receiver B. Therefore, the 'document' (MJ is regarded as virtual information, and the proof of ownership (Α⑽ 丨 INF〇j) is regarded as secret information. In addition, in this embodiment, the secret information is hidden in a Reed-Solomon Code (hereinafter referred to as RS code)). The coded virtual information can still maintain the error correction characteristics of the Rs code. The rs code is an error check code published by Reed and Solomon in I960. It is currently widely used in communication systems. In detail, a Error-correctable (n'k) RS codes refer to the original data of length k. After encoding, they become data codes of length n. When these data codes are transmitted, t = (nk) / 2 or less errors occur. You can restore the error by clicking a certain program. For details, please refer to Beta Wicker and VKBhargave, Reed-Solomon Codes and Their Applications, 1994, which will not be repeated here. 15 (CNS) Α4 »(210X297 ^ 7

The Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs printed 402713 'The sender has an information hiding processor η, is the encoder 14 and the second RS encoder 16'. The receiver B has a corresponding information extraction processor 22, Two RS decoders 26. Among them, the “first RS decoder 24 and the first encoder, the first—decoder pair = 147cRS (ni'ki) θ * ^ 24 as its corresponding decoder; the second” second RS decoder 26 file% After the first RS editor and drinker 14 carries out the poor material code after 后 encoding, and the proof of ownership AQs {iNFQi} is performed through the first editor ㈣16 ... The data horse after the edit of the horse is sent separately to the occupational processor 12. The information hiding processor 12 includes a production machine, which uses a key as a random seed to generate a series of relevant positions in the data code after the Mi encoding of the file, which is used to indicate the proof of ownership. The data code to be inserted after encoding: After being merged, a pseudo-material that is merged can be generated and transmitted to the receiver B through 1. In addition, the information extraction processor 22 of the receiver 0 also uses the same key to generate the same position sequence. ^ As shown in the figure, the maggot data of the mosquito recipe B can be directly decoded by the second RS decoder 24 to generate the required file%. On the other hand, the information extraction process ϋ 22 can generate the sequence of positions actually inserted through the same face h, thereby solving the data code of the proof of ownership. Finally, the second .Rs decoder 26 is used to solve the required ownership certificate AoJINFOJ.

Description of the invention f / 6 When using RS (ni, k), the number of correctable errors that can be tolerated is two; the number of correctable f errors required for transmission is 乂 / 2 ° this Shi's assumption is that in practice, the data used for data hiding = is ~ (It is less than ... So it ’s okay to see the data space of the shell machine and the zang. From the perspective of the data space, that is, the proof of ownership is another corner full. os (NF0J after passing RS (n2, k2) ::% of all the material content%, must be = case 'even if there are tp errors in the actual data transmission, and even: all exist in the proof of ownership A 〇s {卿 〇j inserted position ^ f can still use the RS code error correction ability to make corrections = 't produce the correct f material code.

In the application of the surging virtual field p, the tp value can be determined according to the transmission environment, and the direction ni ki, n2, and k2 are determined by the actual size of the file itself and its proof of ownership. The information hiding technology described in this case uses RS coding technology as an example, but the present invention can also be applied to other technologies The encoding method of the error correction function. An example is as follows: Assume that the "# -RS encoder 14 in Fig. 4 is an rs (1024, 512) encoder, so it has t = (104-512) / 2 = 256 Ministry of Economic Affairs The Central Standards Bureau staff consumer cooperative prints the bit error correction function. Assume that the actual number of errors that may occur during transmission is tp = 56 bits, so the number of hideable information is 256-56 = 200 bits. Assume Aos {INFO} After being encoded by the second RS encoder 16, it is 200 bits. At this time, the information hiding processor 12 can determine 200 positions by KH, and replace the encoding result (200 bits) of the second RS encoder 16. The position corresponding to 200 determined by KΗ in the first rs encoder 14. The process of determining the position by KH can be processed by an appropriate hash function.
