Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.

In the following description, numerous details are set forth to provide a more thorough explanation of embodiments of the present invention, however, it will be apparent to one skilled in the art that embodiments of the present invention may be practiced without these specific details, and in other embodiments, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring embodiments of the present invention.

Example one

As shown in fig. 1, the archive storage method in this embodiment includes:

s101: acquiring an image to be stored and the characteristic information of the image to be stored;

s102: storing an image to be stored, and acquiring image storage information to be stored of the image to be stored;

s103: acquiring characteristic information of each main chain block image in a block chain;

s104: and storing the image storage information to be stored and the image feature information to be stored in the main chain or the sub chain according to the image feature information of each main chain block and the image feature information to be stored, so as to realize the archival storage of the image to be stored.

The block chain comprises a main chain and a sub chain, and the storage information of the image to be stored comprises a storage address and an access method of the image to be stored.

Optionally, the storage information of the image to be stored may be a Uniform Resource Locator (URL) of the image to be stored, and since the block chain itself is not suitable for storing the content with a large data size, the number of the image to be stored may be huge, and is not suitable for being directly stored in the block chain, the image to be stored may be stored by itself in a centralized storage manner, and only the URL of the image to be stored is stored in the block chain, so that access, acquisition, and the like of the image to be stored may be implemented by acquiring the URL from the block chain.

In some embodiments, the obtaining of the image feature information to be stored may be to identify the image to be stored in advance through a preset image identification model to obtain data, such as an image feature value, as the image feature information to be stored. Taking a face image as an example, because faces of different individuals are different, image characteristic values of each individual face image are different, and identification, verification and the like of identity information of the individual corresponding to the face can be realized through the image characteristic values.

In some embodiments, the manner and location of storing the image to be stored may be stored in a manner known to those skilled in the art, and are not limited herein. Optionally, the secure storage of the image to be stored may be implemented by controlling an access rule or the like for storing the address of the image to be stored.

The main chain block image feature information is all image feature information stored in a certain block on the main chain in the block chain, in other words, if a certain block a in the main chain stores image feature information to be stored of three images to be stored, the main chain block image feature information corresponding to the block a is a set of the image feature information to be stored of the three images to be stored.

In some embodiments, storing the image storage information to be stored and the image feature information to be stored in the main chain or the sub-chain according to the image feature information of each main chain block and the image feature information to be stored includes:

if the first similarity is not higher than the first preset similarity threshold, extending a newly-added main chain block on the main chain according to newly-added main chain information, wherein the newly-added main chain information comprises block characteristic information, main chain identification information, image identity information, image characteristic information to be stored and image storage information to be stored.

Each first similarity is not higher than a first preset similarity threshold, that is, no image feature information which is particularly similar to the image feature information to be stored currently is stored in each block of the current main chain, and at this time, it is described that an image which is too similar to the image to be stored is not stored in the block chain, so that the main chain needs to be extended to obtain a new block on the main chain, and the archive storage of the image to be stored is realized on the newly added main chain block. Taking the face images as an example, if the similarity of the two face images is higher than a first preset similarity threshold, it is likely that the two face images belong to the same person, and if a block on a main chain is added to each face image obtained on the block chain, the main chain of the block chain is very long, the information processing speed is very slow, and the subsequent application is not facilitated. By comparing the image characteristic information on the current main chain twice before the main chain block is newly added, the phenomenon that the same person has a plurality of blocks on the main chain can be effectively avoided.

The block feature information includes, but is not limited to, hash, data hash, etc. of the previous block, the main chain identification information is used to identify the newly added main chain block as a block on the main chain, and the image identity information is identity information corresponding to the image to be stored. For example, if the image to be stored is a face image, the image identity information may be person identity identification information corresponding to the face image, such as an identity card number, a job number, a school number, and the like, which may uniquely represent the identity of the person, and all the image identity information corresponding to the image to be stored, which is to be stored in the block chain, is different. The image identity information can be used for conveniently and quickly locking the related information (the storage position of the image, the characteristic information of the image and the like) of the image when the image is searched according to a certain identity in the follow-up process.

Optionally, an exemplary manner of respectively determining the first similarity between the image feature information to be stored and the image feature information of each main chain block may be as follows: comparing the image characteristic information of each main chain block with the image characteristic information to be stored respectively, which can be realized by adopting a similarity comparison mode, and comparing the image characteristic information of the main chain block corresponding to each main chain block with the image characteristic information to be stored one by one.

For example, if the main-chain block image feature information only includes one to-be-stored image feature information M stored previously, the similarity comparison is performed only on the to-be-stored image feature information M and the current to-be-stored image feature information W.

If the main-chain block image feature information includes three pieces of previously stored to-be-stored image feature information M, N, L, similarity comparison is performed between the to-be-stored image feature information M, N, L and the current to-be-stored image feature information W.

In other words, when the first similarity between the image feature information to be stored and the image feature information of each main chain block is determined, it is required to compare each image feature information stored in each block on the main chain with the image feature information to be stored, and when the image feature information of the main chain block includes the image feature information of a plurality of images, the first similarity is the minimum similarity obtained by comparing the image feature information to be stored with each image feature information. For example, the main chain block image feature information includes three stored to-be-stored image feature information M, N, L, and the similarity comparison between the to-be-stored image feature information M, N, L and the current to-be-stored image feature information W is performed to obtain three first similarities S₁、S₂And S₃Three first similarities of S₃Has the smallest value of S₃As the first similarity of the image feature information of the main chain block.

If the image to be stored is subjected to archival storage every time one image to be stored is obtained, the workload is very large, and in many scenes, a lot of images to be archived are often obtained at one time, so that whether the image to be stored is qualified or not can be checked through presetting a certain condition, and the image to be stored is worthy of archival storage. In addition, if the image identity information of a plurality of images is the same in a plurality of images to be archived acquired at one time, for example, face images at a plurality of positions of the same person are obtained, if the whole process of archive storage is performed on each image to be archived, a lot of computing resources are wasted, the processing efficiency is low, if the image to be archived can be preprocessed before the current image to be stored is determined, a plurality of images corresponding to the same image identity information as the current image to be stored are obtained, and when the image to be stored is subjected to archive storage, other images under the same identity information are also subjected to archive storage, so that a lot of resources are saved, and the data processing efficiency is improved.

In some embodiments, before extending the new main chain block on the main chain according to the new main chain information, the determining of the qualification of the image to be stored further includes clustering or comparing.

The images to be archived are collected into a plurality of images which need to be archived, and the images to be archived can be from the same data source like a camera, and can also be snap-shot images from different data sources such as a plurality of traffic checkpoints, snap-shot images of a plurality of cities and the like.

Wherein the clustering process comprises: clustering the images to be archived in the image set to be archived to obtain a plurality of image groups, obtaining a first number of first target archived images, and determining qualification information according to the number, wherein the first target archived images comprise the images to be archived in the image group where the images to be stored are located.

It should be noted that, clustering is performed on each image to be archived in the image to be archived set, and clustering is performed substantially according to the characteristic information of the image to be archived of each image to be archived, so that a plurality of image groups can be obtained, and generally, the images to be archived in each image group all have the same image identity information.

The comparison treatment comprises the following steps: the method comprises the steps of obtaining feature information of images to be archived of other images to be archived except images to be stored, determining second similarity between the feature information of the images to be archived and the feature information of the images to be stored, obtaining a second number of second target archived images, and determining qualification information according to the number, wherein the second target archived images comprise the images to be archived, the second similarity of which is higher than a second preset similarity threshold value.

The determination of the image characteristic information to be archived may be similar to the way the image characteristic information is to be stored, and will not be described further herein. The preset second similarity threshold may be set by a person skilled in the art as needed, and is not limited herein.

Only when the to-be-archived images with the same image identity information as the to-be-stored images exist in the to-be-archived image set, the qualification of archive storage is carried out based on the to-be-stored images, so that the situation that a certain image which is obtained by accident is stored independently can be effectively avoided, and the archival value of the certain independent image is not very high in many scenes. For example, in archiving the face images and the identity information of people who are present in an office building, if a certain person happens to be present in a certain frame of a monitoring video only on a certain day, it may not be very valuable to store the individual archive of the people who happen, and only if the person appears repeatedly in the monitoring video for many times, that is, only if there are many face images of a certain person, a main chain block is newly added to the main chain of the block chain for the person to store the related information of the person. In addition, there may be a certain error in the image feature information of one image, and if the image feature information stored in the main chain block is only obtained from one image, the reliability is limited, which may result in a high error rate of the whole file. By adopting the method that the image characteristic information of a plurality of images is simultaneously stored in the same main chain block, the stability of the image characteristic information in the main chain block can be effectively ensured, and the comparison result is more reliable in the subsequent comparison process.

In some embodiments, determining the eligibility based on the quantity includes qualifying if the first quantity is greater than a first predetermined quantity threshold, and qualifying if the second quantity is greater than the first predetermined quantity threshold;

if the qualification includes qualification, the new main chain block is extended on the main chain according to the new main chain information.

Optionally, if the qualification includes a disqualification, the processing of the image to be stored is stopped.

In some embodiments, if the determination of the qualification includes clustering, first target archival image feature information of the first target archival image is acquired and the first target archival image is stored, first target archival image storage information of the first target archival image is acquired, the first target archival image storage information includes a storage address and an access method of the first target archival image, and the new main chain information further includes the first target archival image storage information and the first target archival image feature information.

In some embodiments, if the determination of the qualification includes a comparison process, second target archival image feature information of the second target archival image is obtained, the second target archival image is stored, and second target archival image storage information of the second target archival image is obtained, the second target archival image storage information includes a storage address and an access method of the second target archival image, and the new main chain information further includes the second target archival image storage information and the second target archival image feature information.

The first target archival image characteristic information and the second target archival image characteristic information may be obtained in a manner similar to that of the image characteristic information to be stored, or in other manners known to those skilled in the art, and are not limited herein. The first and second target archival images are also stored in a manner similar to that of the image to be stored or in a manner known to those skilled in the art.

The newly added main chain block is generated according to the newly added main chain information, so when the newly added main chain information further comprises first target archival image storage information and first target archival image characteristic information, the image characteristic information to be stored, the image storage information to be stored, the first target archival image storage information and the first target archival image characteristic information are stored in the newly added main chain block extending on the current main chain; when the newly added main chain information further comprises second target archival image storage information and second target archival image feature information, the image feature information to be stored, the image storage information to be stored, the second target archival image storage information and the second target archival image feature information are stored in a newly added main chain block extending on the current main chain. That is, for the same batch of images to be archived, under the condition that the first similarity is not higher than the first preset similarity threshold, the images including the same image identity information are stored in the same newly added main chain block.

Since the storage quantity in the same block is too large, which leads to tedious follow-up verification and affects efficiency, the storage information of the second target archival image and the feature information of the second target archival image in the main chain block cannot be recorded without limitation, so before the main chain block is newly added, it is necessary to first determine whether the first quantity or the second quantity exceeds a second preset quantity threshold, if the second preset quantity threshold is exceeded, it is stated that the information to be recorded is too much, at this time, only a part of the information can be selected for recording, and the rest of the information is recorded in the sub-chain of the newly added main chain block. Therefore, the size of the main chain block can be ensured to be proper, and the processing speed of the subsequent block chain data in the using process is improved.

In some embodiments, if the determination of the eligibility includes clustering, obtaining first target archival image feature information of the first target archival image, and storing the first target archival image, obtaining first target archival image storage information of the first target archival image, the first target archival image storage information including a storage address and an access method of the first target archival image, and if the first number is greater than a second preset number threshold, newly adding the chain information further includes selecting the first target archival image storage information and the first target archival image feature information of a second preset number threshold number of first target archival images from each of the first target archival images.

The data selection rule for selecting the first target archival image storage information and the first target archival image characteristic information of the second preset number threshold number of first target archival images from the first target archival images may be in a manner known to those skilled in the art. For example, if the second preset number threshold is 4 and the number of the current first target archival images is 5, then 4 first target archival images are randomly selected from the 5 first target archival images, and the first target archival image storage information and the first target archival image feature information corresponding to the 4 first target archival images are added into the new main chain information to construct a new main chain block.

In some embodiments, if the determination of the qualification includes a comparison process, obtaining second target archival image feature information of the second target archival image, storing the second target archival image, and obtaining second target archival image storage information of the second target archival image, the second target archival image storage information including a storage address and an access method of the second target archival image, and if the second number is greater than a second preset number threshold, newly adding the chain information further includes selecting the second target archival image storage information and the second target archival image feature information of a second preset number threshold number of second target archival images from each second target archival image.

The second target archival image storage information and the second target archival image characteristic information of the second target archival image of the second preset number threshold number selected from the second target archival images may be in a manner known to those skilled in the art. The selection here is similar to the selection for the first target archival image described above and will not be described here again.

In some embodiments, if the determination of the qualification includes clustering, a new added child link block is registered in the new added main link block according to the new added child link information, where the new added child link information includes block feature information, child link identification information, and first target archival image storage information and first target archival image feature information of the first target archival image not included in the new added main link information.

In some embodiments, if the determination of the qualification includes a comparison process, the new added child chain block is registered in the new added main chain block according to the new added child chain information, where the new added child chain information includes block feature information, child chain identification information, and second target archival image storage information and second target archival image feature information of the second target archival image not included in the new added main chain information.

For example, if the second preset number threshold is 4 and the number of the current second target archival images is 5, then 4 second target archival images are randomly selected from the 5 second target archival images, and the second target archival image storage information and the second target archival image feature information corresponding to the 4 second target archival images are added into the new main chain information to construct a new main chain block. And adding second target archival image storage information and second target archival image characteristic information corresponding to the remaining 1 second target archival images into the newly added sub-chain information to construct a new added sub-chain block, wherein the new added sub-chain block is a sub-chain of the newly added main chain block, and the block characteristic information in the newly added sub-chain information comprises the hash and the data hash of the previous block. The sub-chain identification information is used to identify the newly added sub-chain block as a block on the sub-chain. For example, for a first sub-chain block directly extending from the main chain block, the block characteristic information in the first sub-chain block is the hash and data hash of the main chain block, and for a second sub-chain block extending from the first sub-chain block, the block characteristic information is the hash and data hash of the first sub-chain block.

In some embodiments, if there is a first similarity higher than a first preset similarity threshold, determining a target main chain block, and extending a new added sub chain block in the target main chain block according to the added sub chain information, where the new added main chain information includes sub chain identification information, to-be-stored image feature information, to-be-stored image storage information, and block feature information, and the target main chain block includes a main chain block corresponding to the similarity higher than the preset similarity threshold.

For example, a first similarity between the image feature information to be stored currently and the main chain block image feature information of the main chain block M is higher than a first preset similarity threshold, at this time, the main chain block M is a target main chain block, if the target main chain block does not have a sub-chain currently, a newly added sub-chain block is obtained by directly extending the main chain block M, and if the target main chain block already has a sub-chain currently and the last sub-chain block is a sub-chain block G, a newly added sub-chain block is obtained by directly extending the sub-chain block G.

In some embodiments, the image to be stored is an image to be archived in the image set to be archived, and before the extended sub-link block is registered in the target main-link block according to the new incremental sub-link information, any one of the following is further included:

clustering to-be-archived images in an image set to be archived to obtain a plurality of image groups, acquiring first target archived image characteristic information of a first target archived image, storing the first target archived image, acquiring first target archived image storage information of the first target archived image, adding sub-chain information, storing information of the first target archived image and the first target archived image characteristic information, wherein the first target archived image storage information comprises a storage address and an access method of the first target archived image, and the first target archived image comprises the to-be-archived image in the image group where the to-be-stored image is located;

the method comprises the steps of obtaining characteristic information of images to be archived of other images to be archived except images to be stored, determining second similarity between the characteristic information of the images to be archived and the characteristic information of the images to be stored, obtaining second target archived image characteristic information of a second target archived image, storing the second target archived image, obtaining second target archived image storage information of the second target archived image, wherein the new sub-chain information further comprises the second target archived image storage information and the second target archived image characteristic information, the second target archived image storage information comprises a storage address and an access method of the second target archived image, and the second target archived image comprises the images to be archived of which the second similarity is higher than a second preset similarity threshold value.

Optionally, the amounts of the image feature information and the image storage information recorded in the sub-chain may not be limited, in other words, the to-be-archived images having the same image identity information in each batch of to-be-archived images are stored in the same newly added sub-chain block.

In some embodiments, the image identity information includes image identity information hash, the image identity information is stored in a hash mode, so that the information security can be improved, and by utilizing the one-way property of hash operation, the image identity information hash of the block chain can be matched only after the image identity information hash is calculated, so that the archive information of the image identity owner can be obtained, and the image identity information cannot be directly obtained from the block chain.

In some embodiments, the image feature information to be stored includes image feature values and image feature recognition model information. That is, while the image feature information to be stored is acquired, information of an algorithm or a model used for extracting the image feature information to be stored is also recorded into the image feature information together with the image feature value.

Since there may be multiple ways for extracting feature values of an image, and there may be a certain difference between feature values obtained in each way, synchronously storing the image feature value Z1 and the image feature recognition model information in the block chain may be helpful for comparing, processing, and improving the comparison accuracy between the image feature value Z2 and the image feature value Z1 obtained by using different image feature recognition models.

Similarly, the first target archival image feature information and the second target archival image feature information include image feature values and image feature recognition model information.

In some embodiments, the main chain of the block chain includes a plurality of main chain blocks, a plurality of sub-chain blocks extend from a main chain block, the image storage information to be stored and the image feature information to be stored are stored in a main chain block or a sub-chain block, and the plurality of main chain blocks form a double-layer block chain structure.

Optionally, a main chain block in the block chain is sequentially extended with a plurality of sub-chain blocks, that is, the main chain block has only one sub-chain as shown in fig. 2. Other main chain blocks in the chain of blocks may also be extended with respective subchains.

Optionally, at least one main chain block in the block chain simultaneously includes two or more sub-chains, each sub-chain includes the same feature information, where the feature information includes, but is not limited to, shooting year, shooting angle, job information, and the like, for example, the block chain stores face image information, the main chain block stores a plurality of image information that is first stored by a certain person X, the person X has a plurality of face images in dimensions of several years or several angles, and the like, then a sub-chain extends from the main chain block every year, and the sub-chain stores the face images of the person X in the year, so that separate sub-chain storage of image data in different years for the same person can be realized, and subsequent data query and data verification are facilitated.

Optionally, the blockchain in this embodiment adopts a dual-layer blockchain structure, and referring to fig. 2, fig. 2 provides a schematic diagram of a dual-layer blockchain structure, where the dual-layer blockchain has 2 types of main chains and sub-chains, and the sub-chains are created by branching on the main chain blocks. The block structures of the main chain and the daughter chain are similar, both having 1 block head and 1 block body. Referring to fig. 3, fig. 3 is a schematic diagram of a main chain architecture, and as shown in fig. 3, the main chain block header includes 4 data structures, which are the previous block hash, the data hash, the main chain identification information, and the image identification information. Wherein the image identity information may be a hash of the person ID. Note that, for the created block, the hash in the block header is 0, and the image identification information is also 0. The previous block hash is key data for forming a block chain, and is the hash of the whole previous block, which is used for performing data check on the block chain subsequently. The data hash is a whole hash for the block body, and is used for ensuring the data security of the block body and preventing the block body from being tampered. The main chain identification information is used to identify whether the block is a main chain or a child chain. The image identity information is used to match with the image identity. When the image is a face image, the one-way query can be realized by using the hash of the person ID. The personnel id hash of the block chain can be matched only after the personnel id hash is calculated, the archive information of the personnel can be obtained, and the personnel id information cannot be directly obtained from the block chain. Referring to fig. 4, fig. 4 is a schematic diagram of a sub-chain architecture, as shown in fig. 4, a chunk header of a sub-chain includes 3 structures, a previous chunk hash, a data hash, and sub-chain identification information. The previous block hash and data hash have the same meaning as the main chain block, and the sub-chain identification information is used for marking that the block is a sub-chain block. Here the data content of the "previous chunk header hash" of the first child chunk and its associated successor to the main chunk is identical, so we need an identification to distinguish whether the chunk is a main or child. With continued reference to fig. 3 and 4, the bank structure is similar for the main chain blocks and the sub-chain blocks, the bank structure being the main structure for data storage in the block chain. In the dual-layer blockchain provided by the present embodiment, the blocky bodies of the main chain and the sub chain are consistent in the data structure. The < algorithm id, picture url, eigenvalue > triplet is used as a storage structure. The algorithm id is identification information (image feature recognition model information) of the image recognition algorithm used, the picture url is a url address (image storage information to be stored) for accessing the picture, and the feature value is feature data (image feature information to be stored) extracted from the picture by the image recognition algorithm.

The following describes an archive storage method in this embodiment by way of an embodiment, and referring to fig. 5, taking an image to be stored as a face picture, a face personal archive is created in the form of a main chain block structure plus a chain. The picture of each main chain block structure and the branched sub-chains is required to be the picture of the same person, so that the face personal file is constructed. When the main chain block structure is generated, it is the first creation of a face personal profile, where a sufficient number of face pictures are needed to ensure the accuracy of face identification information, so we can require that the number of triples in the main chain block structure needs to be multiple, such as 5. That is, only five groups of triples of at most 5 face pictures are recorded in the main chain block. For a sub-chain, the number of block triplet groups may be any number, depending on the number of face pictures that need to be punched into the sub-chain of block chains.

The characteristic comparison is executed by each block chain link point to obtain characteristic values of a plurality of face pictures, the characteristic values are respectively compared with all characteristic values of the main chain block, and when the face pictures meeting the following conditions are found, the data are linked and stored:

the method comprises the steps of finding that the first similarity of more than one face picture and the characteristic value of each triple of a certain block of a main chain is larger than a first preset similarity threshold. A daughter strand is newly created on the main chain block or extended from the main chain block.

Or, if the second similarity between more than 5 (including 5) face pictures is higher than a second preset similarity threshold, a newly added main chain block is obtained by extending the block behind the main chain, because the specified main chain block can only store 5 pieces of face picture data, if the number of the face pictures is larger than 5, the redundant face picture data is stored by newly creating a sub-chain block on the newly added main chain block.

Optionally, the main chain of the blockchain is extended, and a corresponding service scene is that more than 5 face pictures of the same person are found. At this time we add 1 main chain block after the last block of the main chain. The 'previous block hash' of the newly added main chain block is the hash value of the previous block, the data hash is the integral hash value of the block body of the newly added block, the main chain identification information is the main chain, and the person id number hash value is filled in after the person id hash value of the person. Specifically, if the number of face pictures found is greater than 5, the feature values of other pictures and the picture url are used as the sub-chain data of the main chain block.

Optionally, the block chain sub-chain is extended, and a corresponding service scenario is that a found face picture already has a created face personal file (similarity between a feature value stored in a certain block of the main chain and a feature value of the face image is higher than a first preset similarity threshold), so that the face personal file is enriched. For the main chain block of the face personal file with only the main chain and without the sub-chain, the sub-chain is directly created in the main chain block. For the face profile where the child chain already exists, the extension is performed at the end of the child chain. The data structure is similar to the main chain block and is not described in detail.

Optionally, since the block chain is not suitable for storing content with a large data size, the face image in the scene used in the embodiment has a large data size and is not suitable for being directly stored in the block chain. The picture storage can be performed by using a centralized storage, and only the picture url is stored in the block chain, so that the block chain can be operated quickly.

Through the block chain technology, the files are stored in the block chain, and the following advantages are achieved:

1. decentralized archive storage scheme. In this embodiment, through the decentralized feature of the block chain, each node can access the global information, calculate and process the node information by itself, and match the information chaining, thereby solving the problem.

2. And (4) data security. The block chain technology has excellent tamper-resistant property, and blocks are linked through Hash, so that files are prevented from being deleted and modified.

3. Data privacy. For private data, data that cannot be freely leaked may not be freely decrypted even if the data is leaked. The archive storage method provided by this embodiment stores the image to be stored in an independent storage server, and only stores the image storage information to be stored, such as the picture url, in the block chain, and even if the picture url is acquired, the image to be stored cannot be accessed. For the image identity information, the block chain is also used for hash value storage, and by utilizing the unidirectional property of hash operation, the file information can be obtained only by matching the hash value of the image identity information of the block chain after hash calculation of the image identity information, but the image identity information cannot be directly obtained from the block chain.

The embodiment provides a method for storing archives, which can realize multi-center distributed archive storage without building a new data center. Meanwhile, based on the irreparable modification and safety of the block chain technology, better data safety can be realized for sensitive data.

Taking a face picture as an example, an exemplary face picture archive is constructed, and the archive is applied to some branches, and each branch needs to store and call the archive, see fig. 6, where fig. 6 is an example of a data storage manner in the related art, and in the related art, a face archive data center is needed to store and calculate data. Each branch office stores the data stored by itself into the central storage server through the face archive data center.

Referring to fig. 7, fig. 7 is a schematic diagram of a data storage method for storing an archive according to this embodiment, when the archive storage method provided in this embodiment is applied, a plurality of branches use existing servers to form a double-layer block chain, and storage of a personal face archive can be implemented only by adding a central image storage server, which may be composed of a plurality of servers.

For the traditional scheme, each branch mechanism cannot access the picture characteristic data of other branch mechanisms, cannot perform characteristic calculation, and only can upload the picture characteristic data to a superior central platform, and then the superior uniformly performs characteristic comparison operation on the data to construct a personal file.

After the framework based on the double-layer block chain, each branch mechanism can access all the feature data through the block chain, so that each branch mechanism can perform feature comparison calculation by itself, and then the existing face files are added and linked up, or the new face file information is added and linked up.

The business process taking branch office a as an example is as follows,

if people are compared in the backbone:

the branch organization A acquires one or more pictures from a snapshot library thereof and calculates the characteristic value of the pictures;

the branch mechanism A uses the image characteristic value to compare with the image characteristic values of all blocks in the main chain in the block chain, and if the similarity of the image characteristic values and the blocks x in the main chain reaches a first preset similarity threshold (the first preset similarity threshold can be configured by self), the picture of the branch mechanism A and the picture of the blocks x belong to the same person;

storing the picture of the branch mechanism A to a central picture storage server to obtain a picture url address;

and extending blocks on the subchains on the block x, and filling newly-added subchain information, wherein the newly-added subchain information comprises the hash of the previous block, the hash of data, subchain identification information, image characteristic value algorithm identification information, an image url and an image characteristic value.

No comparison to people in the backbone:

the branch organization A acquires a plurality of pictures from a snapshot library of the branch organization A and calculates the characteristic values of the pictures;

the branch mechanism A uses the image characteristic value to compare with the image characteristic values of all blocks in the main chain in the block chain, and after the image characteristic values of all main blocks in the main chain are compared, the first similarity does not reach a first preset similarity threshold;

and if the mutual similarity of more than 5 pictures (the picture set C) in the plurality of pictures in the snapshot library reaches a second preset similarity threshold value, the pictures are considered to newly form a personal file of one person.

And 5 pictures in the picture set C of the branch A are stored in a central picture storage server, and a picture url address is obtained.

And extending the block on the main chain of the block x, and filling the newly added main chain information, wherein the newly added main chain information comprises the hash of the previous block, the hash of data, main chain identification information, a personnel ID hash value, image characteristic value algorithm identification information, a picture url and an image characteristic value.

And if the number of the picture sets C is more than 5, adding a sub-chain block on the extended block, and adding the picture url and the image characteristic value of the other picture sets C except the data of the pictures included in the added main chain information into the added sub-chain block as the added sub-chain information.
