Overview¶
Access control lets you create a policy to control who can interact with a resource within the PHC. The LifeOmic platform uses Attribute Based Access Control (ABAC) to support both simple and complex access control needs.
For example, if you have a user who wants to download a file from a specific PHC project. Under the ABAC model, the user is performing an action on a resource in an environment. The user, action, resource and environment all have attributes or key/value pairs. A policy contains the attributes that define the privileges of the user.
For detailed information on ABAC, see sections 1 and 2 of the NIST's Guide to Attribute Based Access Control.
Sample Policy¶
Access control allows you to create custom policies for the specific needs of your project. The example below shows a simple policy designed to allow subjects of a study to read their own data. It contains the three main components required to create a PHC access control policy. These components correspond to the ABAC model.
- Permissions - Permissions are the set of actions allowed by the policy. The only action allowed in the sample policy is to Read Data. This permission is further limited by restricting the policy member's action to their own data.
- Resource - Resource options pertain to the resource being accessed. In PHC, the resource can be defined by belonging to a specific dataset or by being a specific type of resource.
- User - The user specifies which people are members of the policy. Group membership defines these members. In our example, a researcher created the group Gradibus Subjects and sent a PHC group invitation email to the research subjects.
ABAC Tables¶
The following tables provide information on PHC access control components.

Resource Types¶
You can restrict the Data Access privileges (Create Data, View Data, Update Data and Delete Data) by resource types.
| Resource Type | UI Path | Description |
|---|---|---|
| Insights (insights) | Resource > Resource Type > Insights | Aggregate data that is viewable on the Insights and Subject Search pages; many of the Subject Search filter options |
| Patient | Resource > Resource Type > Patient | Patient demographics Subject Search filters (e.g. name, identifier) and Subject Viewer demographics details |
| Observation | Resource > Resource Type > Observation | Observation data that is viewable on the Subjects page. |
| Condition | Resource > Resource Type > Condition | Condition data that is viewable on the Subjects page. |
| Procedure | Resource > Resource Type > Procedure | Procedure data that is viewable on the Subjects page. |
| Cohort | Resource > Resource Type > Cohort | Cohort data that is viewable on the Cohorts page or Subject Search |
| GeneSet | Resource > Resource Type > Gene Set | Gene set data that is viewable on the Knowledge, Subject Search and Omics Explorer pages |
