With the rapid development of information technology, people can obtain unprecedented convenience, and all industries are more comprehensively developed. Taking the medical industry as an example, more and more data are transited from paper edition to electronic edition, and the information input mode is changed from handwriting to keyboard input and voice input. For example, a doctor can generate an electronic medical record by manually selecting symptoms in a medical information system, adding medical detection forms or images and prescriptions, and can also express patient information orally and recognize voice of the patient by an electronic device, so that the electronic medical record is quickly obtained and generated, the diagnosis and treatment efficiency is greatly improved, and the main mode that diseases become medical records of a patient generated and stored in a hospital is shortened. However, although electronics improves the quality of medical services, speeds up biomedical discovery, and reduces medical costs, the resources occupied by its information storage and data security as if swordnigh dar keley for the hospital information management department continue to plague healthcare informatization practitioners. This is because, with the great popularity of medical devices, patients often receive a large number of tests to generate a large number of medical images, and due to their great information content, they often occupy a large amount of storage space, which can cause great difficulties with data storage and access. In addition, the electronic medical record contains a plurality of private information, including the name, sex, age, nationality, identification number and the like of the patient, and the medical history includes the past medical history, the present medical history, the menstruation history, the marriage and childbirth history and the like. How to protect such private information from disclosure is crucial. However, in addition to the data access requirements at the hospital, there are access requirements of other parties to obtain some or all of the patient's electronic medical records. For example, a patient needs to obtain his or her past medical history information for subsequent visits; medical management departments (such as medical management departments) need to obtain complete electronic medical records, and audit and count the medical information to provide better social medical guarantee service and avoid over-treatment; for a research institute or a medical enterprise, the research institute or the medical enterprise does not need to know specific private data of a patient, and only needs to obtain part of electronic medical record information used by the research institute.
Although attempts have been made to adopt blockchain techniques, which have the advantages of decentralization, high-redundancy storage, etc., in order to overcome the above-mentioned drawbacks, privacy and security problems still remain.

the generation of the electronic medical record by the doctor and the medical equipment according to the disease condition or the physiological information of the patient specifically comprises the following steps: when a doctor and a patient perform face-to-face or online inquiry or after audio or video recording is performed on the inquiry of the two modes, the sound pickup acquires voice information communicated between the doctor and the patient, transmits the voice information to the background processor for voice recognition, and performs semantic recognition on the voice information through the semantic analysis module, so that text information communicated between the doctor and the patient is displayed on a display in front of the doctor for the doctor to further select, modify or confirm based on preset linguistic information in the electronic medical record database; and prior to the physician making the final diagnosis and prescription, determining whether to attach a laboratory sheet or medical imaging image generated by the medical device from the patient's physiological information to the user's basic information and the aforementioned further selected, modified or confirmed information based on whether the laboratory sheet or medical imaging image exists;
in the process that doctors and medical equipment generate the electronic medical record according to the illness state or physiological information of patients, the processes of voice recognition and semantic recognition comprise: completely acquiring natural language, dividing conversation parties into doctors, patients and even families of the patients according to different sound frequencies of the conversation parties, recorded doctor information and sentence expression modes, wherein firstly, role segmentation is carried out on the basis of the frequency of the conversation parties, then, the recorded doctor information is combined with the sentence expression modes to determine the roles of the doctors, and other characters are determined as the patients and even the families of the patients, when a plurality of people with different frequencies except the doctors answer, the people are determined as the patients and the families of the patients, otherwise, the patients are determined by default; then, based on the sentences of conversation between the two parties and the one-to-one mapping or one-to-many mapping relation between the natural language and the characters, the sentences are identified as the combination of one or more character segments, and compared with the character segments in the electronic medical record database, the character segments with the highest occurrence frequency are selected, so that a complete character sentence pattern is formed;
segmenting the electronic medical record into the first patient information and the second patient information comprises: acquiring an electronic medical record, using privacy related information of a patient as a header, and serializing the information of the electronic medical record; automatically setting a random number range, generating a random number in the preset range as an extraction position increment, extracting bytes from a fixed position, adding the random number to the position to obtain the next extraction byte position until the next byte position is larger than a preset word data uploading upper limit, extracting bytes at the corresponding position from serialized electronic medical record information, using the bytes and a sequentially arranged random number sequence as first information of a patient, and using the rest information as second information of the patient;
when the accessing party needs to access the uploaded electronic duration, forming consensus with the node to be accessed through the block chain comprises: the method comprises the steps that a node where an access party is located sends a request to a block chain so as to broadcast to other nodes in the block chain and send a protocol message, wherein the request comprises a user identification, an authorization code and access data request information of the access party; after each node receives the broadcast, the protocol message needs to be verified, after the verification is passed, the block message is confirmed to the node where the access party is located, the hash value is verified, after the verification is finished, the hash abstract is calculated according to the result, and the node is sorted according to the time sequence; if the node verification protocol message does not pass, the node information is wrong and fails to pass the consensus, the node where the access party is located needs to send a replacement request, and the node which fails to pass the consensus stops the consensus after receiving the replacement request; the verified node submits an information request of the data to be accessed and updates a node state database of the block chain; the electronic medical record data processing process protects the privacy of patients, relieves the trouble of hospital parties on resources occupied by information storage, improves the confirmation speed and ensures the safety and flexibility of access.
10. A computer-readable storage medium storing a computer program which, when executed by a processor, implements the electronic medical record data processing method according to any one of claims 1 to 8.
