System and method for embedding medical information into electronic medical image

Abstract

The invention discloses a system and a method for embedding medical information into an electronic medical image. The method comprises the following steps: a medical image acquisition terminal sends an acquired medical image and a corresponding medical record number to a medical information management server; the medical information management server classifies the medical information of the patient, encrypts the classified medical information, embeds ciphertext data into the medical image of the patient, and sends the processed medical image to a medical image database for storage; the medical staff terminal is used for sending the medical record number to be inquired to the medical information management server; the medical information management server calls the medical image from the medical image database, generates a corresponding ciphertext according to the authority of the medical staff terminal, and feeds back the medical image and the ciphertext to the medical staff terminal;and the medical staff terminal decrypts the ciphertext by using the shared key, and extracts the embedded information in the medical image based on the key obtained by decryption.

Description

technical field [0001] This application belongs to the field of smart medical technology and involves the combination of medical images and medical information. This application proposes a system and method for embedding medical information in electronic medical images. Background technique [0002] The statements in this section merely mention background art related to the present disclosure and do not necessarily constitute prior art. [0003] With the development of the electronic process of medical data, the smart medical system is gradually moving towards practical application. The smart medical information system includes two types of important information, including personal information of patients, important medical information, electronic medical records, etc. Among them, electronic medical images are managed separately from electronic medical records due to their large amount of data (because they require higher resolution). more convenient. However, electronic m...

Problems solved by technology

In order to reduce the risk of privacy leakage, patient information should not be displayed in electronic medical images, but this method is likely to cause a mismatch problem, that is, mistakenly using other people's medical images as the medical images of a patient, resulting in wrong diagnosis and treatment. In serious cases, it is easy to cause medical accidents

[0006] A simple way to deal with it is to embed a code in the electronic medical image, such as a string of numbers, or a barcode, or a two-dimensional code. It is difficult for medical staff to recognize this code with their eyes, but they need to use a code reader to read it. However, this method is also easy to expose patient information, because the processing of electronic medical images is done through computer equipment. When a large number of medical images are used as data for medical research, malicious users or hackers can pass through Analog barcode readers can obtain patient information in medical images, resulting in the disclosure of private information

Further, even if the barcode reader is dedicated to healthcare workers, this attack cannot be prevented
