Security and API Privileges

To effectively protect the device system and user private data, the Tizen security architecture is based on privileges and application signing of the Linux basic security model, which includes process isolation and mandatory access control. Since Tizen, as an open platform, provides a wide range of features and experiences for users with a variety of applications, the users must be able to grant privileges for security-sensitive operations.

Tizen provides API-level access control for security-sensitive operations which, if not used properly, can harm user privacy and system stability. Therefore, applications that use such sensitive APIs must declare the required privileges in the config.xml file. Privileges are categorized into public, partner, and platform levels according to their hierarchy:

  • The public level is the minimum privilege level, which means that any application developed using the Tizen Studio can use these privileges.
  • The partner level privileges require at least a partner-signed certificate which is granted to developers who have a business relationship with the vendor.
  • The platform level is the highest privilege level, and an application that needs these privileges requires at least a platform-signed certificate, which is granted to vendor developers.

Since Tizen platform 3.0, some privileges are categorized as privacy-related and give an option to the user to switch them on and off. If an application invokes a privacy-related privileged API, the Tizen system checks whether the privilege is allowed for the application. For the application to use the API, the privilege must be declared in the config.xml file and the user must have switched it on.

Note In applications with the platform version 3.0 or higher, if you use privacy-related privileged APIs, make sure that the user has switched the privilege on before making the function call. Otherwise, the application does not work as expected.

Since Tizen 4.0, the status of privacy-related privileges can be resolved at runtime using the Privacy Privilege API (in mobile and wearable applications).

The Tizen Studio also provides privilege checker tools to check whether the Tizen application source code contains any privilege violations. For more information, see Verifying Privilege Usage.

The API version restriction of privileges are deprecated since platform version 5.0. So, if you are develeoping an app with an earlier API version and need information about supported version, see this page. The page does not include privileges issued after 4.0.

Non-API Bound Privileges

Tizen application privileges are loosely bound to APIs, so most of the privileges can be identified by the APIs that the application calls. However, there are some privileges that are not coupled with the Tizen APIs. To allow easy identification, those privileges are mapped to corresponding system resources that are similar to other privileges.

The following table lists the non-API bound privileges:

Table: Non-API bound privileges

Privilege Level Privacy Description
http://tizen.org/privilege/mediastorage public Storage When you connect the device to a computer (Windows® or macOS) through USB, you can access a dedicated media storage area shown as massive media storage. This region of the storage is called media storage and is usually used for multimedia files, such as photos, videos, and music files. Since this storage area is used for user private data, access to it must be protected with a privilege.
If your application does not have this privilege, no file operations into the media storage area succeed and you receive a permission denied error. If you have this privilege, you can read and write directories and files, create new files, and delete files in the storage area.
http://tizen.org/privilege/externalstorage public Storage Similar to the media storage, many devices support external storages, such as MicroSD card or USB memory. As with the media storage, the access to an external storage must be protected with a privilege.
If your application does not have this privilege, all file operations fail with a permission denied error. If you have this privilege, you have full access to the external storage.
