Digital Signature on a DICOM Medical Image File / 中国医学物理学杂志

ABSTRACT

Objective: To ensure the integrity、non-repudiation、authenticity of pictures and relevent messages by making a digital signature for a DICOM file. Methods: By using OpenSSL toolkits and dcmsign of DCMTK toolkits, make a digital sig nature for the relevent messages of DICOM medical image and then save it behind of the DICOM file. Results: We can evaluate integrity、non-repudiation、authenticity of pictures and relevent messages in the DICOM file which has been made a digital signature. Conclusion: To make a digital signature in a DICOM file by using the OpenSSL toolkits and dcmsign of DCMTK toolkits can realize the security when DICOM file transported in remote medical treatment and PACS.
