Detailed Description
In order to assist copyright parties to maintain rights and improve the efficiency of digital resource copyright authentication, the embodiment of the invention provides a digital resource copyright authentication method, a device, a system and a storage medium.
First, some terms related to the embodiments of the present invention are explained to facilitate understanding by those skilled in the art.
Hash (Hash) algorithms, i.e. Hash functions. The one-way cipher system is one irreversible mapping from plaintext to ciphertext, and has only encryption process and no decryption process, and hash function can change the input in any length to obtain fixed length output. This one-way feature of the hash function and the fixed-length feature of the output data allow him to generate messages or data. The hash algorithm maps a binary of arbitrary length to a shorter binary of fixed length, this small binary becoming a hash value. Hash values are a unique and extremely compact representation of a piece of data as a value. If a piece of plaintext is hashed and even if only one letter of the piece is altered, the subsequent hash will produce a different value. It is computationally infeasible to find two different inputs whose hash is the same value, so the hash value of the data can verify the integrity of the data.
The so-called block chain technology, bt (block chain technology) for short, also called distributed book technology, is an internet database technology, and is characterized by decentralization and public transparency, so that everyone can participate in database recording. The block chain comprises: transaction (Transaction): an operation, resulting in a change of the state of the ledger, such as adding a record; block (Block): recording the transaction and state results occurring within a period of time, which is a consensus on the current ledger state; chain (Chain): the system is formed by serially connecting blocks according to the occurrence sequence and is a log record of the whole state change.
It should be noted that the terminal device in the present invention may be a terminal device such as a Personal Computer (PC), a tablet PC, a Personal Digital Assistant (PDA), a Personal Communication Service (PCs) phone, a notebook, a mobile phone, etc., or a Computer having a mobile terminal, for example, a portable, pocket, hand-held, Computer-embedded or vehicle-mounted mobile device, which can provide voice and/or data connectivity to a user, and exchange voice and/or data with a wireless access network.
Furthermore, the terms "first," "second," and the like in the description and in the claims, and in the drawings, in the embodiments of the invention are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein.
Reference herein to "a plurality or a number" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The digital resources involved in the embodiments of the present invention refer to various off-line and on-line electronic resources, such as digital video resources, digital e-book resources, digital music resources, and other entertainment resources, which are manufactured by digital technology and distributed through conventional distribution channels or distributed to the public through the internet.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
As shown in fig. 1, which is a schematic diagram of a system structure of a digital resource copyright authentication method according to an embodiment of the present invention, the digital resource copyright authentication method according to the embodiment of the present invention may be applied to a blockchain network, where the blockchain network includes a storage node 11 and an authentication node 12, and the storage node 11 and the authentication node 12 may be terminal devices or server devices with stronger computing power, and the like.
Any user and service platform of application in the network can apply to join the block chain network to become a block chain user. After each blockchain user applies to join the network successfully, a public key address and a private key password are obtained, wherein the public key address can be used as a user identifier of the blockchain user in the blockchain network, and the public key address corresponds to the private key password one by one.
It should be noted that, in implementation, the storage node 11 and the authentication node 12 may also be combined as needed.
In the embodiment of the invention, in order to ensure the uniqueness and non-tamper property of the digital resource property right, the original copyright side of the digital resource can upload the digital resource created by the original copyright side to the storage node in the block chain network for storage after applying for joining the block chain network to become a block chain user.
As shown in fig. 2, a schematic flowchart of a process for obtaining original copyright information for a storage node in a blockchain network may include the following steps:
and S21, the storage node receives the original copyright information uploaded by the first user.
The original copyright information is at least one of the following information by using a private key applied in advance: the resource identification corresponding to the digital resource, the user identification applied in advance and the timestamp are signed to obtain the signature, and the private key corresponds to the user identification one by one.
In specific implementation, before an original copyright party releases digital resources created by the original copyright party in a network, a hash value corresponding to the created works is calculated by using a hash algorithm to serve as a resource identifier of the released digital resources, and information such as a user identifier obtained when the original copyright party joins the blockchain network and a current timestamp obtained when the original copyright party releases the digital resources is used for generating original copyright information, wherein the user identifier obtained when the original copyright party joins the blockchain network can be a public key address distributed by the blockchain network, and further, the obtained original copyright information can be signed by using a private key. And uploading the obtained original copyright information and the created digital resources to a blockchain network for storage, wherein in specific implementation, the original copyright information can be encrypted by using a private key password obtained when the original copyright information and the created digital resources are added to the blockchain network.
The original copyright party can upload the obtained original copyright information by using the terminal equipment added into the block chain network.
It should be noted that the first user involved in step S21 may be the original copyright owner, or may be a legitimate user authorized by the original copyright owner.
And S22, storing the received original copyright information by the storage node.
And S23, when the network consensus time arrives, the storage nodes broadcast the original copyright information in the blockchain network, so that each storage node in the blockchain network stores the original copyright information respectively.
In specific implementation, when the consensus time is reached, the obtained original copyright information and digital resources are broadcasted in the block chain network, so that all storage nodes in the block chain network store one copy of the original copyright information and the digital resources.
Specifically, at certain intervals, all storage nodes in the block chain network perform one-time consensus, that is, information and resources received in the current consensus period are collected to form a block structure stored on the network. After receiving the original copyright information, any storage node searches in a block chain stored in the storage node according to a resource identifier in the original copyright information so as to determine that no digital resource corresponding to the received resource identifier exists in the block chain stored in the storage node, and finally, the information and the resources stored in all the storage nodes in the block chain network are agreed, and the agreed information and the agreed resources are written into a historical digital resource database.
In a specific implementation, the consensus period of the blockchain network may be set according to actual needs, for example, the consensus may be performed once per hour, or once per day, for example, the consensus is performed once per hour, assuming that the last consensus time is 8:00, the next consensus time is 9:00, each storage node in the blockchain network can monitor whether the consensus time is reached through a maintenance timer, for any storage node, if the consensus time arrives according to the self-maintained timer, the information and resources newly added during the current consensus period (i.e. 8:00-9:00) are broadcast in the blockchain network, after receiving the information and the resources broadcasted by the storage node, the other storage nodes write the received information and the resources into a historical digital resource database maintained by the other storage nodes. Likewise, the storage node needs to store the information and resources synchronized by other storage nodes in a historical digital resource database maintained by the storage node.
The information related in the embodiment of the present invention may include information required for protecting copyright resources, such as copyright streaming information and copyright transaction information, and the resource may be a digital resource that needs to be protected by copyright, for example, a written work created by an original copyright side, and the like.
Other service platforms or users in the blockchain may purchase digital resource rights from the copyright parties. The purchasing process needs to obtain the private key signature of the copyright party, when the method is implemented specifically, the buyer and the user purchase and obtain partial or all use rights of the digital resources in a mode of transferring accounts of copyright authors, and the buyer and the seller confirm the transaction success through the private key signature. The private key signature of the copyright party may be a manual signature or implemented in an intelligent contract, which is not limited in the embodiment of the present invention.
In order to ensure the reliability and traceability of the digital resource copyright transaction record, in the embodiment of the invention, the digital resource copyright transaction information is uploaded to the storage node in the block chain network for storage. As shown in fig. 3, which is a schematic flowchart of a process for obtaining digital resource copyright transaction information by a storage node, the process may include the following steps:
and S31, the storage node receives the copyright transaction information uploaded by the second user.
Wherein, the copyright transaction information is generated by using at least one item of the following information: the copyright transaction timestamp, the user identification of the users of the two copyright transaction parties, a second hash value generated by the private key signature of the two copyright transaction parties and copyright transaction information.
In specific implementation, after users of both parties of copyright transaction complete copyright transaction, the transaction timestamp, public key addresses applied by both parties in the blockchain network, hash values generated by private key signatures of both parties, other transaction information and the like can be used for generating copyright transaction information.
The second user involved in step S31 may be the current copyright holder of the digital resource, which may be the original copyright holder, or the copyright holder who succeeded in the digital copyright transaction.
And S32, the storage node stores the received copyright transaction information.
And S33, broadcasting the copyright transaction information in the blockchain network by the storage nodes when the network consensus time arrives, so as to respectively store the copyright transaction information in each storage node in the blockchain network.
The implementation of this step is similar to the above-mentioned consensus step of the original copyright information in the blockchain network, assuming that the consensus period is set to 1 day, the last consensus time is 0:00 of 2018, 7, month and 1, the next consensus time is 0:00 of 2018, 7/month and 2/day, each storage node in the blockchain network can monitor whether the consensus time is reached through a maintenance timer, for any storage node, if the consensus time arrives according to the self-maintained timer, the copyright transaction information newly added in the current consensus period (i.e. 0:00 on 1/7/2018-0: 00 on 2/7/2018) is broadcasted in the blockchain network, after receiving the information and the resources broadcasted by the storage node, the other storage nodes write the received information and the resources into a historical digital resource database maintained by the other storage nodes. Similarly, the storage node needs to store the copyright transaction information synchronized by other storage nodes in a historical digital resource database maintained by the storage node.
In this way, original copyright information, copyright transaction information, and the like can be recorded in the storage node in the blockchain network. Based on this, the embodiment of the present invention further provides a digital resource copyright authentication method, as shown in fig. 4, which may include the following steps:
s41, the authentication node scans the digital resources propagated in the network.
In specific implementation, the authentication node in the blockchain network may scan the digital resources propagated in the network at certain intervals.
The authentication node may scan digital resources existing in the network by using a network scanning tool, and for convenience of understanding, the digital resources scanned by the authentication node are digital resources a of the Tencent video.
S42, the authentication node judges the scanned digital resource is copyright protection resource, if yes, the step S43 is executed, otherwise, the step S41 is executed.
In this step, the authentication node judges whether the scanned digital resource is a copyright protection resource or not through the digital resource stored in the storage node. Specifically, the authentication node may query whether the storage node stores the digital resource a, if so, it indicates that the digital resource a is a copyright protection resource, and if not, it indicates that the digital resource a is not a copyright protection resource.
And S43, reading the copyright stream transfer information corresponding to the scanned digital resource from the storage node.
In this step, if it is determined in step S42 that the digital resource a is a copyright protected resource, the copyright transfer information corresponding to the digital resource a is read from the storage node. The copyright conversion information comprises original copyright information and copyright transaction information.
S44, the authentication node determines the authentication result according to the read copyright stream forwarding information.
In this step, the authentication node judges whether the current user of the digital resource which is transmitted and scanned has the current operation authority according to the read copyright process information, and determines the authentication result according to the judgment result.
Specifically, the authentication node judges the current copyright owner according to the copyright circulation information of the digital resource A, and the current copyright owner is assumed to be the user ID1, the user ID2 and the user ID 3. The authentication node judges whether the Tengcong video is a copyright side, namely whether the Tengcong video is one of user ID1, user ID2 and user ID3, if so, the Tengcong video is determined to be the copyright side, and otherwise, the Tengcong video is determined not to be the copyright side.
S45, the authentication node stores the authentication result in the storage node and returns to execute the step S41.
In this step, the authentication node may send the authentication result to the storage node for storage, so as to assist the copyright holder of the digital resource to perform right maintenance, and the like.
In the digital resource copyright authentication method provided by the embodiment of the invention, digital resources, original copyright information and copyright transaction information thereof are stored in a block chain network, each digital resource has a unique record and is traceable and incapable of being copied and tampered, so that the reliability and the authenticity of digital resource copyright transfer information are ensured.
