The responsibility of maintaining patient’s records is with medical personnel. The medical personnel are supposed not to disclose any kind of medical information related to the patient. This is also applicable for the medical information discovered by medical personnel in connection with the treatment of the patient. With the advent of technology and its penetration into the medical field in the form of telemedicine and e-health, the challenge of maintaining confidentiality is becoming complex. The confidentiality needs to be protected from storage of medical image or transmission of image from a medical database center to other. Nowadays, the information of patient is printed in the corner of the medical image. This can be accessed by anybody or even the machine can access and store the information. During an electronic transmission, the patient information may be intercepted by a third party. This may lead to big lawsuit. Apart from these security issues, for scenarios such as medical research, the image should be used but patient information should be hidden. Also for diagnostic purposes, the information of the patient should be readily accessible to the medical personnel. These constraints lead to the necessity of suitable security techniques for medical image storage and transmission. If suitable security techniques are not applied, privacy of patients will be stake. Hence, numerous methods are being implemented by individuals, governments and businesses for secured transmission of patient’s data. For patient’s privacy protection, secured transmission requires techniques like cryptography and watermarking. These techniques achieve confidentiality and integrity. In this work, a new approach has been developed for secured transmission of medical images.

维护患者记录的责任在于医务人员。医务人员不应透露任何与患者有关的医学信息。这也适用于医务人员发现的有关患者治疗的医学信息。随着技术的出现及其以远程医疗和电子医疗的形式渗透到医疗领域，保持机密性的挑战变得越来越复杂。需要保护机密性，以防止存储医学图像或将图像从医学数据库中心传输到其他数据库。如今，患者信息被打印在医学图像的一角。任何人都可以访问，甚至机器也可以访问和存储信息。在电子传输过程中，患者信息可能会被第三方拦截。这可能导致大诉讼。除了这些安全问题外，对于医学研究等场景，应使用图像，但患者信息应隐藏。同样出于诊断目的，医务人员应易于获取患者的信息。这些约束导致需要用于医学图像存储和传输的适当安全技术。如果不采用适当的安全技术，则患者的隐私将受到威胁。因此，个人，政府和企业正在采用多种方法来安全地传输患者数据。为了保护患者的隐私，安全传输需要使用密码学和水印技术。这些技术实现了机密性和完整性。
