PostDICOM Security

Cloud Security

PostDICOM's top priority is secure storage and secure retrieval of the patient data. We provide following security measures to ensure data is safe at all times.

Storage Regions and Servers

PostDICOM operates on thirteen different regions to comply with regulations. Each region works isolated from each other and patient data (DICOM images, clinical documents, and patient information in the database) are stored only on that region. If one region has more than one location, servers replicate data among themselves.

Session and Data Transfer Security

PostDICOM uses secure communications (SSL) internally between its servers. Also, user requests are only supported over HTTPS. Moreover, when a user logs in, a session is created and it remains active until user logs out or a timeout occurs. Only requests from valid sessions are processed by PostDICOM servers.


PostDICOM uses AES 256 encryption by default. When user data reaches to PostDICOM, servers first encrypt data with AES 256 and then stores them on Microsoft Azure storage of that region.

Password Policy

All of the users have to use strong passwords for their accounts. Passwords must be at least 8 characters long and must contain at least one uppercase, one lowercase and one special character. This is enforced by PostDICOM password set up policy. Also, PostDICOM supports Two Factor Authentication (2FA) and users can use Two Factor Authentication (2FA).

Anonymization of Patient's Data

If the identity of the patient is important, users can anonymize DICOM images during Upload process. DICOM images are anonymized at the client machine and then uploaded to the PostDICOM.

Reliable, Secure, Fast and Easy DICOM Sharing

Cloud Share

Sharing medical images and clinical documents is a necessity in many situations and current professions need a reliable, secure, fast and easy DICOM images access. Moreover, they need to see clinical documents to perform a correct diagnosis.

For many years, clinics and hospitals used on-premise PACS on the site. In those systems, they distribute DICOM images by burning images into CDs and distribute them by mail. Distribution of CDs is a cumbersome process, and no one knows when the recipient gets the CDs and when will the evaluation occurs. Moreover, CDs contain a basic DICOM viewer and they support only one operating system. If the CD viewer is not compatible with the operating system of the recipient, they cannot view and process the images at all.

PostDICOM Cloud PACS provides sharing solutions by overcoming the following difficulties.

Big data size: Number of the images captured by the modalities (such as CT, MRI, XA, PET) are increasing every year. For example 10 years ago the number of images taken for Thorax CT was around 30-50 images (15-25 MB). Currently it is around 500-5,000 images (250-2,500 MB). It is a challenging job to distribute high volume images to the recipients. PostDICOM uses streaming technology, and users can access the images in seconds. PostDICOM servers process the study and send result picture to the client.

Sharing with a link: Authenticated user can share DICOM studies with the clinical documents with the recipients they want. They can assign passwords to the shared link and can set an expiration date for images access. Moreover, users can see shared links on the user interface and can cancel them at any time.

HTML5 DICOM viewer and clinical document viewer: PostDICOM provides HTML5 DICOM images, and clinical documents viewer and users do not need to install any software on their hardware. Supported platforms are Windows, MacOS, Linux, IOS and, Android.

Advanced viewing tools: PostDICOM provides advanced tools. These tools include MPR (Multi Planar Projection), MIP (Maximum Intensity Projection), MINIP (Minimum Intensity Projection), AVGIP (Average Intensity Projection), 3D Construction, PET/CT FUSION, PET/MR FUSION. Users can access and use these tools from the HTML5 interface.

Security: PostDICOM communications are performed through https using SSL (Secure Socket Layer). Also, users can assign passwords for each of the created shared links, and they can only be accessed using the password provided. Moreover, users can see shared links on the user interface and can cancel them at any time.

In short PostDICOM Cloud PACS provides tools for reliable, secure, fast and easy sharing. Users can register for free, and upload their DICOM files and clinical documents. Then, they can create a share link and mail it to the recipient within the system. As soon as recipient receives the shared link and the access password, he or she can access DICOM images and clinical documents without installing any software on their device.

PostDICOM Regions
