Detailed Description
Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
With the development of computer technology, the blockchain technology (also called distributed book technology) has attracted much attention due to its advantages of decentralization, public transparency, non-tamper-ability, trustiness, etc.
In particular, the blockchain technique is a decentralized distributed database technique. Each piece of data in the block chain is broadcasted to the block chain nodes of the whole network, and each node can store the whole amount of consistent data. Blockchain techniques require that the state of each node remain consistent, including the state of the database, etc. In order to ensure the consistency of the database state, the sequence of executing the blockchain transaction is required to be ordered and kept consistent in each node, and each node executes the transaction according to the sequence to complete transaction verification, implementation, data chaining and the like. Taking the blockchain application of the ether house as an example, a timestamp is created when a transaction is received, the transaction is written into a transaction pool, and the transactions are sequenced according to the timestamp; and when mining, executing transactions according to the sequence of the transaction timestamps, and updating the account information after executing each transaction into the database to realize the updating of the account state of the database.
A block chain consists of individual blocks (blocks). A block is similar to a record of a database, and each time data is written, one block is created. Fig. 1 shows an example of the composition of one block. As shown in fig. 1, each block comprises two parts: a Head (Head) for recording a feature value of the current block; and a block Body (Body) containing actual data. The sector block portion may also be omitted when the actual data size is small and may be included in the block header.
The block header contains a plurality of feature values of the current block, including but not limited to: a generation time; the hash value of the actual data (i.e., the block), the hash value of the last chunk, and so on.
Here, "hash" refers to a process in which a computer calculates a feature value having the same length for an arbitrary content. The hash length of the blockchain is 256 bits. That is, regardless of the original content, a 256-bit binary digit is finally calculated. Meanwhile, it can be ensured that corresponding hashes are different as long as the original contents are different.
For example, the hash value obtained by hashing the string 123 is a8fdc205a9f19cc1c7507a60c4f01b13d11d7fd0 (hexadecimal), the conversion to binary is 256 bits, and only 123 can obtain the hash. (theoretically, other strings could also get this hash, but with very low probability, and can be considered approximately impossible.)
Due to the above-described characteristics of hash calculation, it can be considered that: the hash of each block is different, and the blocks can be identified through the hash; and if the contents of a block change, its hash must change.
The chunks are in a one-to-one correspondence with the hashes, and the hash of each chunk is calculated for the "chunk header" (Head). That is, the feature values of the block header are sequentially connected together to form a long character string, and then the hash is calculated for the character string.
Hash as SHA256 (block head)
As the above shows the calculation formula of the block hash, SHA256 is a hash algorithm of the block chain. Note that this formula only contains the block header and no block body, i.e., the hash value is uniquely determined by the block header,
fig. 2 shows a schematic diagram of the "connection" of blocks in a block chain. As shown in the figure, since the block header (data) of the current block includes the hash value (prev: H ()) of the previous block, if the content of the current block becomes changed or the hash of the previous block becomes changed, the hash of the current block must be changed. This is especially important for blockchains. If someone modifies a block, the hash of the block becomes changed. In order for the following block to be attached to it (since the next block contains the hash of the previous block), the person must modify all following blocks in turn, otherwise the modified block leaves the block chain. Since hash computation is time consuming, it is almost impossible to modify multiple blocks in a short time unless one has mastered over 51% of the computation power of the whole network.
By the linkage mechanism, the reliability of the block chain is guaranteed, and once data is written, the data cannot be tampered. This is also the name "blockchain" since each block is linked to the last block based on the correlation of hash values.
The invention utilizes the characteristic that data cannot be tampered once written in the block chain technology, and ensures that the author declares the creation time and the creation content of the work of the author to be effective, thereby improving the original environment of the intellectual property market.
FIG. 3 shows a schematic flow of a work content distribution method according to one embodiment of the invention. The work issued based on the invention is helpful to prove the intellectual property rights of the issuer to the work because the issuing time and the specific content can be traced and verified.
In step S310, binary information is generated based on the content of the work of intellectual property to be verified. Here, the work of intellectual property right to be verified refers to a work capable of describing intellectual labor achievement of an intellectual property right owner, and particularly may include a work of copyright to be verified, for example, may include various kinds of creative works. For example, plain written works (e.g., novels, editorial, etc.), pictorial works, musical works, audiovisual works, dance works, architectural design works, and the like may be included. To facilitate machine storage, the works described above may be saved in a computer-readable form, such as saving novice works as text files, music works as audio files, dance works as video files, paintings and architectural design works (e.g., drafts) as image files, and so forth. In other embodiments, the content may be intellectual property rights related to the content in a broader sense, such as a document or picture reflecting the author's creative idea or even a trademark design. Regardless of the type of intellectual property right, the content of a work may typically include at least one of: a text file corresponding to a written work (e.g., a novel or innovative technical document); audio and/or video files corresponding to audiovisual works (e.g., songs, movie plays, stage plays, etc.); and an image file corresponding to an image work (e.g., a painting, a building, a trademark, or other design drawing, etc.).
Subsequently, at step S320, a current hash value of the current chunk is generated based on at least the previous hash value of the previous chunk, the binary information, and the current timestamp, and at step S330, the current chunk including at least the current timestamp, the binary information, and the current hash value as a chunk header is issued.
In an embodiment of the present invention, in addition to including the hash value and the timestamp of the previous tile in the tile header, which is consistent with tile generation needs, binary information of the content of the work to be verified (which may be the content of the work itself or a representation thereof, as described below) may be included in the tile header itself. Therefore, the hash is carried out according to the current block head to obtain the current hash value. The chunk including the current hash value is then published and used for hash value generation for the next chunk. Since any tampering with the tile itself will cause a change in the hash value and require re-computation of the hash values for all subsequently released tiles, by generating and incorporating the tile into the chain of tiles, the tile itself can be rendered untrustworthy, and therefore the timestamp contained in the tile header of the tile and the content of the work can be used to verify that the content of the work was completed by the releasing party prior to the time represented by the timestamp.
In different application scenarios, the binary information for inclusion in the chunk header and hashing may correspond to or represent the complete work itself.
For example, for literary works, especially chapter-wise updated network novels, the volume per chapter is small. In the case where one block header has a size of 1M, since 1M may generally correspond to 40-50 ten thousand words of content, it is possible to completely convert the text corresponding to the literary work into a binary file contained in the block header.
Corresponding to larger representations of work content, such as video, audio, or pictures, only a representation or portion thereof may be stored within the tile header. In one embodiment, a simplified work content representation may be generated for the complete work content representation and binary information may be generated based on the simplified representation. For example, for a pictorial representation, an author may first take the pictorial representation to obtain a corresponding picture, then turn down the resolution of the picture (e.g., save the original 5M of the picture as a 500k low-definition picture), and generate binary information based on the low-definition picture. In subsequent verifications, the low-definition picture can still be used to prove that the work was created at the time of tile release, as long as the low-definition picture retains the primary details of the pictorial work. Different reduced representations may be chosen for different works. For example, a black and white line drawing of a building work, demo of a music work, or the like can be selected as simplified content that generates binary information and can represent the work itself.
In other embodiments, multiple copies of binary information may also be generated based on the complete work content of the intellectual property right to be verified, where each copy of binary information corresponds to a portion of the complete work content. Subsequently, one block may be generated from each piece of binary information. For example, a certain audio may be divided into three parts, corresponding to three binary information, and three blocks may be generated accordingly. The three blocks may be contiguous or spaced apart depending on whether there are other blocks in the network generated during the last two block generation processes. Thus, non-tamperable distribution of complete work content may be achieved by generating multiple tiles for a single work.
The binary information included in the block header as above may be in plaintext. Therefore, after the decryption is carried out through the issued digital signature in the verification process, the binary information in the block header can be directly obtained. After the network novel file is released, all nodes can directly read the content of the network novel file according to the digital signature, so that the releasing mode is particularly suitable for single-chapter releasing of network novel, and an author can rapidly release own works. In the present invention, such an issue mode may be referred to as an "immediate mode".
Alternatively, the generated binary information may be encrypted using a work encryption private key, wherein the encrypted binary information is included within a chunk header of a current chunk for generation of the current hash value. In other words, the binary information included in the block header is binary information encrypted by the private key. Therefore, after the block header is decrypted by acquiring the digital signature, other nodes can only acquire the encrypted binary information, and the content of the work cannot be directly restored. In this case, only when the publishing node publishes the work decryption public key corresponding to the work encryption private key, other nodes can decrypt by using the public key, and finally obtain the work content information of the plaintext. In the present invention, such an issue mode may be referred to as a "delay mode".
"deferred mode" is particularly useful for distribution, such as writing an entire book or making an entire album. For example, a writer may write while publishing blocks, the content for each block of the book being encrypted via the same private key. The corresponding public key is published after the writer completes the entire book or after the book is published and issued. If someone is found to plagiarism during authoring, the public key can also be used in advance to decrypt the content on the blockchain for forensics. Thus, the author can prove that the author has finished the corresponding work content at the time of timestamp marking by publishing the behavior of the block and the content contained in the block, and further enables other nodes to really acquire understandable work content by publishing the public key.
As described above, one block must include a block header and may also include a block body. For this purpose, in order to implement the storage function of the block, a block of the work content with the intellectual property right to be verified may also be issued, wherein the block includes an encrypted or unencrypted version of the work content.
In one embodiment, the publication of the tiles may be published to the full network. In another embodiment, the publication may be made only to specific nodes. At this time, the publishing node may adopt an invitation system to invite a national department, a trusted larger publisher and a literature platform to participate, so as to publish the current block to the authority node. Therefore, the node quality can be ensured, and meanwhile, the content is prevented from being illegally spread. This distribution to authoritative nodes is particularly applicable when the entire work content is contained in the block header of the block.
In addition, author information may be included within the tile header in addition to the necessary prior hash value, timestamp, and binary information for the work, such that generation of the current hash value likewise needs to be based on the author information, thereby facilitating confirmation of the immediate author of the work. Further, in the block header or the block body of the block, mode information for specifying when the work content is distributed may be further included, for example, mode information for immediately distributing or delaying distribution when the above specification is made.
Fig. 4 shows an example of a fragment of a block chain of blocks distributed according to the invention. As shown, author information, time stamp, work information, and mode information may be included in the tile header of each tile, and a hash value may also be generated based on the above information.
In one embodiment, the three work tiles shown in the figure may be a segment of a common blockchain. In other embodiments, a dedicated chain of work authentication blocks may be created, and the three work blocks shown in the figure are one segment of the chain of work authentication blocks. In other words, the block chain involved in the present invention can be a dedicated or a general block chain. The generation and publication of the current tile may then be based on at least one of: obtaining a hash value of a previous block from a private intellectual property verification block chain and issuing the current block to the private intellectual property verification block chain; and obtaining the hash value of the previous block from the universal block chain and issuing the current block to the universal block chain.
After the blocks are released as described above, a subsequent intellectual property verification method may also be performed. Fig. 5 shows a schematic flow chart of an intellectual property verification method according to one embodiment of the present invention. It is understood that the node performing the authentication is another node than the publishing node, such as any node in the whole network, or an invited node in the node invitation system, such as an authoritative node. The issuing of authoritative nodes is particularly suited in connection with the aforementioned dedicated blockchains.
In step S510, the current block as issued above is decrypted based on the issued digital signature. In step S520, based on the authenticity of the hash value in the chunk header of the current chunk, the authenticity of the binary content issued at the current timestamp in the chunk header of the current chunk is verified.
In a case where the binary content in the block header of the current block is the binary content encrypted via the work encryption private key, the verification method may further include: obtaining a work decryption public key corresponding to the work encryption private key; and decrypting the encrypted binary content according to the work decryption public key to obtain readable work content.
The distribution of work content and corresponding verification methods based on blockchain techniques are described above with reference to fig. 3-5. In other embodiments, the above-mentioned scheme can also be realized by corresponding functional devices.
Fig. 6 shows a composition diagram of a work content distribution apparatus according to an embodiment of the present invention. As shown in the figure, the work content distribution apparatus 600 includes a binary information generation unit 610, a hash value generation unit 620, and a block distribution unit 630.
