Abstract
This paper proposes a method for storing and securing medical images in DICOM format. Other methods offered affect the quality of the image. The solution proposed here is based on the AES256 algorithm in Galois/Counter Mode (GCM) which already integrates authentication and signature processes to ensure the integrity of the images manipulated. This solution is implemented by using the Phyton programming language under the DJANGO framework, libraries such as NUMPHY, PYDICOM, MYSQLCLIENT, and PYCRYPTODOME. The results obtained after experimental tests give us a good average encryption and decryption time. The difference in the mean value of time between encryption and decryption is quite small in view of the tests carried out. We obtain saving on storage space owing to the fact that the proposed solution directly stores the encrypted image. The manipulated image is not altered.

Summary
The consumption of intangible goods has significantly increased, resulting in the circulation of large amounts of data on computer networks, in particular on the internet. The particular case of the exchange of digital medical images which contain a great deal of information on patients and must imperatively be protected in order to guarantee medical secrecy regulated by Law. To provide solutions to this issue of digital medical images privacy, several protection methods have been developed to guarantee their Availability, Integrity and Confidentiality (AIC). To provide solutions to this issue of digital medical images privacy, several protection methods have been developed to guarantee their Availability, Integrity and Confidentiality (AIC) Among these protection methods, cryptographic ones seem to be the most suitable. The proposed solution will improve the storage capacity of medical image backup systems This will ensure the security of the medical image in Picture Archiving and Communication System (PACS) while ensuring the AIC criterion.
