According to the embodiment of the invention, the corresponding participation accounts are set according to each link of medical image labeling management, and related operation data of the processor corresponding to each participation account is linked, so that data set labeling, data set sharing and data set application can be integrated into a system, the full life cycle management of medical image labeling is realized, quality control and standard implementation are carried out on medical data uploaded to a platform, and the standard formulation and execution of the medical labeling data are completed; based on the characteristics of the block chain, the related operation data cannot be tampered, the safety and reliability of uploaded data are guaranteed, the data of each block of the block chain can be obtained through the generated traceability identification code of the block chain, and the traceability of the operation data of each link of the medical image annotation management is achieved.
In some embodiments, the participation accounts corresponding to each link of medical image annotation management comprise a project responsible member account, an auditor account, an annotator account and an administrator account;
the operation authority of the project responsible member account on the corresponding processor comprises the steps of creating a medical image data annotation task, dividing the medical image data annotation task into a plurality of subtasks and distributing the subtasks to a designated annotator account;
the operation authority of the annotator account on the corresponding processor comprises processing the distributed subtasks and uploading the corresponding image annotation version;
the operation authority of the auditor account on the corresponding processor comprises auditing the image annotation versions generated by the annotator accounts and sending qualified image annotation versions to the project responsible member account;
the operation authority of the project responsible administrator account on the corresponding processor further comprises the steps of selecting a final image annotation version from the received qualified image annotation versions, and sending a release sharing application about the selected image annotation version to the administrator account;
the operation authority of the administrator account on the corresponding processor comprises auditing the issuing and sharing application, generating an issuing and sharing contract and executing the generated issuing and sharing contract.
When the user operates according to the authority of each participating account, the following scenes can be realized:
dividing the medical image data set into a subtask A, a subtask B and a subtask C by using an annotation task, wherein the subtask A is annotated by an annotator, after the annotation of the subtask A is completed, the auditing staff audits the annotation quality, if the auditing is not passed, the annotator marks again or abandons the annotation task, the project responsible staff redistributes the subtask to other annotators, and if the auditing is passed, the annotation of the subtask A is completed, so that an image annotation version V1.1 is generated; similarly, after the subtasks B and C are labeled, image labeling versions V1.2 and V1.3 are generated, the task version numbers are determined according to the sequence of the completion of the subtasks, if the last subtask C is completed, the version number of the medical image data set is V1.4, and the image labeling version with the version number of V1.4 is selected as the final image labeling version.
In some embodiments, the medical image data set is labeled in three ways, disease classification, lesion detection, and lesion segmentation. Selecting a front-end form for the data annotation mode; the disease classification means that the images are classified, firstly, the label classification is set, and then, the whole image is labeled; the focus detection means that focus areas in an image are detected, firstly, label categories are set, then, the focus areas are drawn by rectangles, and an area coordinate set is generated; the focus segmentation is to draw the focus contour in the image and is in pixel level. Firstly, setting label categories, then drawing out the outline of the focus by using a mouse, and generating a focus area coordinate set. And finally generating file formats such as json, csv, TFRecord and the like through three labeling modes.
The generating and issuing of the sharing contract is a process of generating an order for sharing and acquiring the points of the data set, and the executing and issuing of the sharing contract is a process of sharing and acquiring the points and 'point trading'. Taking "generating a publishing sharing contract" as an example, the fields required for generating the "chain code" of the block chain are as follows: whether points are needed, how many points are needed, usage rules, whether business is allowed, whether self-use is allowed, whether research is allowed, these fields are packaged as a "block" and "uplink" is performed.

In the embodiment of the invention, a user can obtain the data of each block of the block chain by scanning the traceability identification code, so that the operation data of each link of the medical image labeling management can be inquired at any time. When a user, such as an algorithm engineer, needs data of each block of the block chain, the user can send a data download application through the processor, and the application condition items of the data download application can include description of application purposes, recommenders, agreement on data security related terms and the like. When the data download application is checked, besides checking the application condition items, a face recognition verification mechanism can be further adopted to verify the user, so that the authority verification of the applicant is realized. For example, the steps of the face recognition verification mechanism may be: clicking to start verification and generate a two-dimensional code, entering a face recognition interface by using a mobile phone code scanning function, comparing the face recognition interface with a face information base input in advance, and automatically submitting a data downloading application flow by the system after the comparison is successful.
In some embodiments, the uploading the operation data on the processor corresponding to the participation account to the block of the corresponding block includes:

The encryption of the operation data can adopt encryption means of different authority levels according to different operation data, such as common operation data, DES encryption, SHA-256 encryption of operation data with certain characteristics, SHA-512 encryption of operation data related to medical core technology confidentiality.
In some embodiments, the operating permissions of the administrator account on the corresponding processor further comprises:

and decrypting the ciphertext data of the corresponding block according to the access authority of the participation account to the ciphertext data on each block to generate a decrypted ciphertext.
