Detailed Description
One or more embodiments of the present disclosure provide a method, an apparatus, and a system for processing blockchain data, so as to achieve the purpose of ensuring data security while using a blockchain technique.
In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present disclosure, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in one or more embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments of the present disclosure without making any creative effort shall fall within the protection scope of one or more of the embodiments of the present disclosure.
Fig. 1 is a schematic flow chart of a block chain data processing method according to an embodiment of the present disclosure, as shown in fig. 1, the method includes:
s102, a plurality of hash data corresponding to a plurality of service data recorded in a block in the first block chain are obtained.
And S104, performing obfuscation encryption processing on the plurality of hash data according to a preset obfuscation encryption processing mode to obtain at least one obfuscated target hash data.
And S106, carrying out fragmentation processing on at least one target hash data.
And S108, respectively storing the fragmented target hash data into a second block chain.
In one embodiment, hash data corresponding to business data recorded in a block of the first blockchain is an account book of a transaction recorded in the first blockchain, and the account book may be accessible only to nodes in the first blockchain. The account is obfuscated and encrypted and then stored in a second blockchain, and the obfuscated and encrypted account stored in the second blockchain may be accessible to an external user. Therefore, on one hand, an external user such as the public can access the account book to ensure the data to be true and transparent, and on the other hand, the external user acquires the account book subjected to the obfuscated encryption processing, so that the account book subjected to the obfuscated encryption processing is difficult to analyze to obtain the relevant information of the true transaction amount, and the safety of the transaction information is also ensured.
Therefore, according to the technical scheme, the finally stored target hash data can be accessed by an external user by mixing the plurality of hash data corresponding to the plurality of service data, but the external user can hardly analyze the target hash data to acquire information such as transaction scale and transaction magnitude. Therefore, the data in the block chain can be guaranteed to be real and transparent, and meanwhile, the data safety can be guaranteed, so that a user can be facilitated to better protect own services when using the block chain.
It should be appreciated that in embodiments of the present application, obfuscating the encryption process of the hash data may include a variety of ways.
Optionally, in an implementation manner, the content composed of a plurality of hash data may be hashed to obtain one hash data.
For example, assuming that Hash data corresponding to 4 storage records in a block of the block chain are HashA, HashB, HashC, and HashD, respectively, the Hash data HashABCD after the encryption process is Hash (HashA + HashB + HashC + HashD), where the function Hash () represents a Hash calculation function, such as MD5, SHA-1, SHA-256, SHA-384, and SHA-512, and so on. In the bitcoin system, the hash algorithm used is SHA-256.
Optionally, in another implementation manner, any one of the hash data may be divided into a plurality of portions of content, and then hash calculation may be performed respectively to obtain a plurality of hash data corresponding to the plurality of portions of content.
For example, assuming that Hash data corresponding to one storage record in a certain block of the block chain is HashA, the HashA may be split into HashA1 and HashA2, and then Hash processing is performed on the HashA1 and the HashA2, respectively, so as to obtain HashA1 ═ Hash (HashA1) and HashA2 ═ Hash (HashA2), where the HashA1 'and the HashA 2' are Hash data obtained by performing obfuscation and encryption processing on the HashA. Of course, the HashA can be split into 3 parts, 4 parts or even more, and the specific split number of parts, how split, is configurable.
Optionally, in another implementation manner, the content composed of the plurality of hash data may be subdivided into a plurality of portions of content, and hash calculation may be performed on each portion of content, so as to obtain a plurality of hash data corresponding to the plurality of portions of content.
For example, suppose that hash data corresponding to 4 storage records in a certain block of the block chain are HashA, HashB, HashC, and HashD, respectively, and the content HashABCD of the hash data is (HashA + HashB + HashC + HashD); the HashABCD may be divided into HashABCD1 and HashABCD2, and Hash calculation is performed on HashABCD1 and HashABCD2 to obtain Hash (HashABCD1) and Hash (HashABCD2), where the Hash (HashABCD1) and the Hash (HashABCD2) are multiple Hash data corresponding to the multiple portions of content.
In addition, it should be understood that the obfuscation scheme according to the embodiment of the present application may further perform multiple layers of obfuscation encryption processing, that is, perform one or more layers of obfuscation encryption processing on hash data after one layer of obfuscation encryption processing. The algorithms for obfuscating the encryption process at different layers may be the same or different.
For example, assuming that Hash data corresponding to 4 storage records in a certain block of the block chain are HashA, HashB, HashC, and HashD, respectively, the Hash information HashABCD after the first layer obfuscation encryption is Hash (HashA + HashB + HashC + HashD); the second layer obfuscates the encrypted Hash data into Hash (HashABCD1) and Hash (HashABCD2), wherein HashABCD is HashABCD1+ HashABCD 2.
Optionally, in another implementation, the hash data may be subjected to one or more times of fragmentation processing and/or hash calculation. Specifically, the hash data may be subjected to only the fragmentation processing to obtain the target hash data, or the fragmentation processing and the hash calculation may be combined to perform the obfuscation encryption on the hash data to obtain the target hash data.
A detailed obfuscated encryption processing method is described below.
Firstly, the hash data is sliced according to a specified slicing rule to obtain a plurality of first data segments.
Wherein, the step of assigning the fragmentation rule comprises the following steps: carrying out a fragmentation rule according to the specified data length; for example, if the specified data length is 64KB, the hash data is fragmented according to the rule that each data fragment is 64KB in size; or, a rule for slicing according to a specified time length; for example, if the specified time is 1 second, fragmentation is performed according to the hash data stored in each second, and if the hash data stored in the current 1 second is one data fragment, the hash data stored in the next 1 second is the next data fragment.
And secondly, performing hash calculation on each first data segment to obtain a plurality of second data segments.
Finally, obfuscating the encrypted target hash data is determined from the plurality of second data segments. Specifically, the second data segment may be directly determined as the target hash data, and the second data segment may be further subjected to one or more times of fragmentation processing and/or hash calculation, so as to finally obtain the target hash data.
In this embodiment, an obfuscated encryption processing manner is described in which hash data is first sliced, and then hash calculation is performed on the sliced data fragments. Obviously, due to the diversity of the obfuscating encryption processing modes, the target hash data after the obfuscating encryption processing is difficult to be known by external users, and therefore the security of the target hash data can be ensured.
Of course, besides the above-mentioned obfuscated encryption processing manners, other various obfuscated encryption processing manners may also be adopted to perform obfuscated encryption processing on the hash data, including a manner of combining multiple fragmentation processing and multiple hash calculation, and the order of the multiple fragmentation processing and the multiple hash calculation is not limited. The more times of fragmentation processing and/or hash calculation, i.e. the more complicated the obfuscated encryption processing manner, the higher the security of the obtained target hash data.
In an embodiment, before hash data corresponding to service data recorded in a first block chain is acquired, it may be determined that a data viewing permission of the first block chain is visible only to a first specified user group, for example, only to each node in the first block chain; and determining that the data viewing permissions of the second blockchain are visible to all users, e.g., external users such as the public can access the data.
Wherein the first specified group of users may be one user or a plurality of users.
In this embodiment, since the first blockchain is only visible to the first designated user group and is invisible to other external users, the hash data corresponding to the service data stored in the block in the first blockchain are difficult to be known by the external users, so as to ensure the security of the hash data corresponding to the service data; in addition, the second block chain is visible to all users, that is, all users can know the obfuscated and encrypted target hash data stored in the second block chain, so that the transparent authenticity of data in the block chain is guaranteed, and even if external users know the obfuscated and encrypted target hash data stored in the second block chain, the external users cannot know the real data of the service data because the obfuscated and encrypted processing mode corresponding to the target hash data is unknown, so that the safety of the service data is ensured, and the users can better protect own services when using the block chain.
In an embodiment, when the obfuscated and encrypted at least one target hash data is stored in the second block chain, the obfuscated and encrypted at least one target hash data may be firstly subjected to fragmentation processing, and then the fragmented target hash data is respectively stored in the second block chain.
In this embodiment, the target hash data included in each segment corresponding to the segment processing is not more than the predetermined number, and a total length of the predetermined number of target hash data should not be more than a maximum length of the data recorded in the chunk in the second chunk chain. Therefore, when the obfuscated and encrypted at least one piece of target hash data is sliced, the target hash data can be sliced in a manner that each slice contains a fixed number of pieces of target hash data, wherein the fixed number should not be greater than a predetermined number.
In this embodiment, after the obfuscated and encrypted at least one piece of target hash data is subjected to fragmentation processing, a plurality of fragments are obtained. Therefore, when the fragmented target hash data is stored in the second block chain, the target hash data contained in each fragment can be stored in the second block chain as a service record.
In one embodiment, the obfuscated encryption processing manner may be stored into the third blockchain and the data viewing permissions of the third blockchain determined to be visible only to a second specified group of users.
Wherein the second designated group of users may be one user or a plurality of users. The second designated user group may be the same or different from the first designated user group (i.e., the user group visible for the first blockchain). The second specified user group may be a worker related to the data stored in the first/second blockchain, such as a maintainer of the blockchain, and the user(s) may manage, such as store, update, and the like, the hash data stored in the first/second blockchain; alternatively, the user(s) may also manage the obfuscated encryption processing manners stored in the third block chain, such as storing, modifying, and the like.
In this embodiment, the confusion encryption processing mode is separately stored in the third block chain, so that the second specified user group can conveniently know the confusion encryption processing mode, and the actual data of the service data is obtained by obtaining the confusion encryption processing mode. Moreover, since the third block chain is only visible to the second designated user group and other external users are invisible, the external user is difficult to know the confusion encryption processing mode stored in the third block chain, so that the real data of the service data is difficult to know, and the security of the service data is ensured.
In an embodiment, the obfuscated encryption processing manner may also be stored in the first block chain, and since the first block chain is only visible to the first designated user group and is invisible to other external users, the obfuscated encryption processing manner stored in the first block chain is difficult to be known by the external users, so that the external users are difficult to know the real data of the service data, and the security of the service data is ensured.
In this embodiment, the obfuscated encryption processing mode and the hash data corresponding to the service data are stored in the first area chain together, which not only can ensure the security of the service data, but also can save the occupation of the block chain by the obfuscated encryption processing mode.
In summary, particular embodiments of the present subject matter have been described. Other embodiments are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may be advantageous.
