Abstract
With the popularization of wireless communication and smart devices in the medical field, mobile medicine has attracted more and more attention because it can break through the limitations of time, space, and objects and provide more efficient and quality medical services. However, the characteristics of a mobile smart medical network make it more susceptible to security threats such as data integrity damage and privacy leakage than those of traditional wired networks. In recent years, many digital signature schemes have been proposed to alleviate some of these challenges. Unfortunately, traditional digital signatures cannot meet the diversity and privacy requirements of medical data applications. In response to this problem, this paper uses the unique security attributes of sanitizable signatures to carry out research on the security and privacy protection of medical data and proposes a data security and privacy protection scheme suitable for smart mobile medical scenarios. Security analysis and performance evaluation show that our new scheme effectively guarantees data security and user privacy while greatly reducing computation and communication costs, making it especially suitable for mobile smart medical application scenarios.
Highlights
With the swift development of the Internet and smart devices, mobile medicine has emerged at the historic moment
We regard the main contributions of our scheme to be as follows: (i) We propose a system model suitable for data security and privacy protection in smart mobile medical scenarios (ii) We propose a privacy-protection scheme based on sanitizable signature for smart mobile medical scenarios
The concept of a sanitizable signature was first proposed by Ateniese et al [14] in 2005, which can break through the limitations of traditional digital signatures and support an entity designated by the original signer to modify the signed message within the scope of authorization and generate a new signature without any interaction with the signer
Summary
With the swift development of the Internet and smart devices, mobile medicine has emerged at the historic moment It is a new type of medical model that can break through the limitations of objective factors such as time, space, and objects. Sanitizable signature [14] is a type of digital signature that supports controlled modification of signed messages This feature makes it guarantee the integrity and authenticity of medical data and effectively hide sensitive information of patients (specific sensitive information can be flexibly set according to different information sharing objects), which follows the “minimum necessary” disclosure standard of HIPAA privacy rules [15] and promotes the use of value-added medical information and improves the efficiency of the scheme.
