"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled.
In this document, "a" or "an" means not only "but also" more than one ". In this document, "first", "second", and the like are used only for distinguishing one from another, and do not indicate their importance, order, and the premise that each other exists, and the like.
Referring first to fig. 1, fig. 1 is a schematic flow chart of a verification method of a handheld control device according to an embodiment of the invention. In the embodiment shown in fig. 1, where the handheld control device is used to control a medical imaging device (not shown), the verification method 100 may include the steps of:
step S110: registering information of the handheld control device in an imaging system of the medical imaging device;
step S120: displaying the verification identification through a display screen of the medical imaging equipment; and
step S130: the handheld control device is authenticated based on the authentication identification.
Specifically, the handheld control device is used to control a medical imaging device (see reference numeral 310 shown in FIG. 3). The medical imaging device may be any of a variety of medical imaging devices, for example, an X-ray medical imaging device. It will be readily appreciated that the various illustrations presented below are intended to illustrate the principles of the present solution and are not intended to limit the medical imaging device to X-ray medical imaging devices.
In step S110, information of the handheld control device is registered in the imaging system (see reference numeral 30 shown in fig. 3) of the medical imaging apparatus. In embodiments, a user of the imaging system (e.g., a medical professional) enters a predetermined information, such as a characteristic identifier of the handheld control device, into a user group of the imaging system. The characteristic identifier may be identification information capable of uniquely identifying the handheld control device, such as a device serial number of the handheld control device or other identification information generated based on the device serial number, or may also be other information customized by the user, which is not limited in this disclosure.
In step S120, a verification identifier is displayed on the display screen of the medical imaging device, wherein the verification identifier contains login information for verifying the handheld control device. In embodiments, the validation logo may be a two-dimensional code or bar code or other suitable form. Taking the verification identifier as a two-dimensional code as an example, the verification identifier may be a quick response code (QR code). In a preferred embodiment, to further improve security assurance, the two-dimensional code may be a dynamic two-dimensional code that changes at regular time. For example, the two-dimensional code can be set to be a dynamic two-dimensional code which changes according to a preset time, namely, the validity period of the two-dimensional code exists according to the requirements of the actual application occasions. Those skilled in the art, such as developers, may preset the change time of the two-dimensional code as required, or in a modified embodiment, may be set by a medical staff, and the present invention is not limited in this respect. Further, the two-dimensional code may be an encrypted two-dimensional code. Those skilled in the art can select a suitable encryption method to encrypt the two-dimensional code according to the actual application requirement, for example, a symmetric encryption algorithm such as AES, DES, 3DES, and the like.
The login information may include a valid login user name and a valid password of an imaging system of the medical imaging device. In an embodiment, in the case that the two-dimensional code is an encrypted two-dimensional code, the login information may further include an authorization code. For example, the authorization code may be a random code randomly generated by the video system.
In step S130, the handheld control device is authenticated based on the authentication identification.
In an embodiment, authenticating the handheld control device based on the authentication identification (step S130) may include: scanning the verification identifier by using the handheld control equipment to obtain a scanning result; decrypting the scanning result to obtain login information; and logging in the imaging system of the medical imaging equipment by using the login information. It is easy to understand that after the encrypted two-dimensional code is scanned by the handheld control device, the obtained login information is transmitted back to the image system of the medical imaging device through the decryption process, login verification is completed, and the medical imaging device can be controlled only by the handheld control device which passes the login verification. For example, the handheld control device is a verified valid control device only if the authorization code returned by the handheld control device is consistent with the random code randomly generated by the image system and sent to the handheld control device.
Alternatively, in an alternative embodiment, multiple encryption mechanisms may be employed. Specifically, the authorization code, the user name, and the password may be encrypted respectively. For example, the scanning result may be decrypted based on the preset information to obtain an authorization code, and the scanning result may be decrypted again based on the authorization code to obtain a user name and a password for logging in the image system. In an embodiment, the preset information is an equipment serial number of the handheld control equipment or preset information generated based on the equipment serial number of the handheld control equipment. In an embodiment, the authorization code is a random code randomly generated by the vision system. In other words, the authorization code can be encrypted by using the random code generated by the imaging system, and the login user name and the password of the imaging system are encrypted by using the authorization code, so that a multiple encryption mechanism is realized, and the safety of the medical imaging equipment can be further improved.
The encryption and decryption processes described above are schematically illustrated below in conjunction with fig. 2A and 2B, to which the present invention is not limited. Fig. 2A is a schematic diagram illustrating a two-dimensional code encryption process according to an embodiment of the invention, and fig. 2B is a schematic diagram illustrating a two-dimensional code decryption process according to an embodiment of the invention.
As shown in fig. 2A, at one end of the image system, a user name a, a password B, and an authorization code C for logging in the image system are encrypted by any selected encryption method to form an encrypted two-dimensional code D. The encryption process can be completed by using any encrypted information set by a user of the image system as a key. For example, the aforementioned characteristic identifier, that is, the device serial number of the handheld control device or other identification information generated based on the device serial number, may be used as a key, or other information customized by the user may be used as a key, which is not limited by the present invention. Alternatively, some of username a, password B, and authorization code C may be encrypted while other information is sent in clear, as the invention is not limited in this respect. For example, only the authorization code C is encrypted, while the user name a and the user name B are sent in clear.
As shown in fig. 2B, after the encrypted two-dimensional code D is scanned by the handheld control device, a scanning result E is obtained, and at one end of the handheld control device, the scanning result E is decrypted by using the aforementioned secret key and a corresponding decryption method, so as to obtain login information included in the original two-dimensional code, that is, the user name a, the password B, and the authorization code C.
And then, the handheld control equipment transmits the login information obtained from the two-dimensional code back to the image system to finish the verification and login process.
Alternatively, to improve security, the invention may adopt other encryption manners to generate the encrypted two-dimensional code, and the contents are not limited to the above-mentioned examples. For example, the authorization code (such as the aforementioned random code) may be encrypted according to a predetermined rule to obtain an encrypted random code. In an embodiment, the device serial number of the handheld control device may be used as a key to encrypt the authorization code. And encrypting the user name and the password for logging in the image system by the authorization code to obtain the encrypted login user name and the encrypted password. And then, generating a two-dimensional code as a verification identifier by using the encrypted random code and the encrypted login user name and password. Thus, the security can be further improved by the multiple encryption mechanism. In contrast, after the two-dimensional code in this embodiment is scanned by the handheld control device, decryption is completed at one end of the handheld control device by using the key and the corresponding decryption method, so as to obtain login information, i.e., the user name, the password, and the authorization code.
In the embodiments illustrated above, the handheld control device may be various devices that can be used for remote control, and preferably, the handheld control device may be an electronic device including a display screen, such as an electronic device like a smart phone or a palm computer, and may also be a handheld control terminal including various electronic devices, such as an electronic device that is accommodated in the accommodating part and control keys that can be set on the accommodating part as required.
The present invention also provides a medical imaging system, as described below in conjunction with fig. 3. Fig. 3 is a schematic diagram of a medical imaging system 300, as shown in fig. 3, including a medical imaging device 310 and a handheld control device 320, according to an embodiment of the present invention. Wherein the handheld control device 320 and the medical imaging device 310 are wirelessly connected and the handheld control device 320 authenticates and controls the medical imaging device 310 by any of the methods described above.
In an embodiment, the handheld control device 320 includes a processor 50, and the processor 50 may be configured to: determining the information of an object to be detected and setting imaging parameters; previewing the formed image; and post-processing the resulting image. In a preferred embodiment, medical imaging system 300 may be an X-ray medical imaging system.
