+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,

+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+The data classification module of OpenHarmony provides hierarchical data protection policies and related APIs. \(Currently, OpenHarmony does not provide implementations for specific APIs. These APIs must be implemented by the device vendors to protect the security of data on OpenHarmony devices.\)
+
+The data classification module provides the following APIs \(into two submodules\):
+
+-   APIs for setting and obtaining the data label: With these APIs, you can set and obtain the security level of a file to be written to the disk.
+-   APIs for controlling cross-device data access based on the device security level: The distributed cross-device data transmission service can use these APIs to obtain the highest data security level supported by the peer device.
+
+The two submodules only contain API definitions, but do not implement these APIs. The following figure shows the architecture of the data classification module.

+## 简介<a name="section11660541593"></a>
+
+在OpenHarmony中，数据分级保护模块负责提供数据分级的保护策略。数据分级保护模块提供了数据分级相关的接口定义。（OpenHarmony当前不提供实际的功能实现。依赖设备厂商实现接口对应的功能，对搭载OpenHarmony的设备上的数据提供安全保护）。
+
+数据分级保护模块当前提供如下接口定义：
+
+-   数据分级标签设置和查询接口：对业务生成的文件数据提供设置和查询风险等级标签的接口，业务可使用该接口设定和查询落盘文件数据的风险等级，使该文件在系统中具有对应的数据风险分级标识。
+-   基于设备安全等级的数据跨设备访问控制接口：提供基于设备安全等级的数据跨设备访问控制的接口，分布式跨设备数据传输业务可使用该接口获得对端设备可支持的数据风险等级。
+
+为实现上述接口定义，数据分级保护模块当前包含数据分级标签设置查询接口和基于设备安全等级的数据跨设备访问控制接口两个子模块，模块中仅包括接口定义，而不包含实际的功能实现，其部署逻辑如下图：
