The DICOM attributes to add after the application of the DICOM attribute confidentiality profiles
| Attribute | Tag | Description | Type |
|---|---|---|---|
| Private data element characteristics sequence attribute | (0008, 0300) | Characteristics of private data elements within or referenced in the current SOP instance | 3 |
| Deidentification action sequence attribute | (0008, 0305) | Actions to be performed on element within the block that are not safe from identify leakage | 3 |
| Patient identity removed | (0012, 0062) | The true identity of the patient has been removed from the attributes and the pixel data | 3 |
| De-identification method | (0012, 0063) | A description or label of the mechanism or method use to remove the patient's identity. May be multi-valued if successive de-identification steps have been performed | 1C |
| De-identification method code sequence | (0012, 0064) | A code describing the mechanism or method use to remove the patient's identity | 1C |
| Burned in annotation attribute | (0028, 0301) | Indicates whether or not image contains sufficient burned in annotation to identify the patient and date the image was acquired | 3 |
| Recognizable visual features attribute | (0028, 0302) | Indicates whether or not the image contains sufficiently recognizable visual features to allow the image or a reconstruction from a set of images to identify the patient | 3 |
| Longitudinal temporal information modified | (0028, 0303) | Indicates whether or not the date and time attributes in the instance have been modified during de-identification | 3 |
| Encrypted attributes sequence attribute | (0400, 0500) | Sequence of items containing encrypted DICOM data | 1C |
| Original attributes sequence attribute | (0400, 0561) | Sequence of items containing all attributes that were removed or replaced by other values in the top level dataset | 3 |
Type 3: optional; Type 1C: conditional
