Project Experience
AI: Face Deep Forgery Defense Method Based on Traceable-Adversarial Watermark Protection
中文名：基于溯源-对抗保护水印的
人脸深度伪造防御方法研究
项目领域和技术栈：本项目属于人工智能中的计算机视觉领域。在实现过程中，我使用了python语言和pytorch深度学习框架。
This project belongs to the field of computer vision in artificial intelligence. For the technology stack, I used the Python language and Pytorch deep learning framework.
研究背景与意义：我们生活中有一种技术叫深度合成技术。这种技术可以生成以假乱真的图像、视频和音频等合成内容。深度合成技术在不同领域都有创造性应用。例如，著名电影《速度与激情7》利用这种技术“复活”了保罗·沃克。当深度合成技术被恶意滥用时，正向的合成技术就变成了负面的伪造手段。深度伪造技术可能会带来影响国际关系、新闻舆论、侵犯公众利益等危害，所以对深度伪造技术的防御就十分重要。
For the research background: There is a technology in our daily life called deep synthesis technology. This technology can produce fake images, video and audio and other composite content. Deep synthesis technology has creative applications in different fields. For example, the famous film Fast & Furious 7 used this technology to “bring back” Paul Walker. When deep synthesis technology is maliciously abused, positive synthesis technology becomes a negative means of counterfeiting. Deep forgery technology may bring harm such as affecting international relations, news and public opinion, so the defense of deep forgery technology is very important.
我的项目就是基于这个背景，提出一种溯源-对抗保护水印，实现嵌入一个水印同时具备溯源和针对深度伪造技术的对抗保护两个功能。溯源功能是通过提取人脸图像中的水印从而判断这张图像的主人。对抗保护功能可以在深度伪造技术对图像恶意篡改时扰乱图像的生成，主要表现为生成失真扭曲的篡改图像。
My project is based on this background. I proposes a Traceable-Adversarial Watermark, which can embed a watermark with both traceability and adversarial protection against deep forgery technology. Totally two functions. The traceability function is to determine the owner of the image by extracting the watermark in the face image. The adversarial protection function can disturb the image generation when the deep forgery technology maliciously modifies the image. As a result, it produces distorted images.
技术实现：模型架构包含水印嵌入编码器、水印提取解码器、水印鲁棒性增强模块和深度伪造对抗性约束模块。编码器用于将水印图像嵌入到原始人脸图像中生成嵌入水印的重建图像。解码器用于从图像中提取水印。水印鲁棒性增强模块用于提高水印的鲁棒性，在遇到高斯模糊、压缩等图像操作时，水印仍然可以稳定保留在图像中。最后的深度伪造对抗性约束模块是为了给图像添加对抗和扰乱深度伪造技术的能力。
For the Technical implementation, The model architecture includes a watermark encoder, a watermark decoder, a watermark robustness enhancement module and an adversarial learning module.
The encoder is used to embed the watermark image into the original face image to generate the reconstructed image that is identical to the original image. The decoder is used to extract the watermark from the image. The watermark robustness enhancement module is used to improve the robustness of the watermark, and the watermark can still be stably retained in the image when meeting image operations such as Gaussian blur and compression. The final adversarial learning module is designed to add the ability to counter and disrupt deep forge techniques to images.
Internship Experience
我有两段技术实习，一段是在滴滴出行。滴滴出行是国内一个大型的互联网科技公司，它的业务是关于网约车的。我所在的部门是公司最核心的乘客推荐引擎开发功能。我的职务是后端开发实习生。
我的实习工作可以分为三部分：独立开发报警阻断模块、协助mentor完成日常平台开发需求和参与调研和开发新业务。
I had two technical internships, one in Didi Chuxing. Didi Chuxing is a large Internet technology company in China Mainland, and its business is about ride-hailing. My department is the company’s core passenger recommendation engine. My position is back-end development intern.
My internship can be divided into three parts: independently developing alarm blocking module, assisting mentor in completing daily platform development requirements, and participating in new business development.
我着重描述我的独自开发经历。
I will concentrate on my independent development experience.
The company’s alerting platform was overwhelmed by excessive alerts during extreme conditions, such as heavy rain or snow, which have caused inefficiencies and overwhelming the system.
I developed an alert-blocking module using Golang and Redis to handle this situation.
My goal was to ensure that this module effectively filtered out unnecessary notifications during emergencies. I designed the module to allow users to customize parameters such as city, alarm type, and blocking duration.
I took the initiative to develop the alert-blocking module using Golang and Redis, which consisted of three main components: the user interface, the alerting platform, and the module itself. The user interface interacted with the module’s API to set alerts and parameters for blocking. The alerting platform utilized the module’s API to determine whether alerts should be blocked, while the module regularly sent users updates on currently blocked alerts.
In this project, I experienced the whole process from module design, implementation and launch, which not only improved my programming and software development ability, but also improved my team cooperation and problem solving ability.
The other internship is in a financial company and my role was data development&analysis intern.
In this internship, I mainly used python programming language, MySQL and SQL Server to deal with database and data analysis, and smart-BI to generate the final data analysis risk control reports.
I Implemented data interaction among third-party software, company databases, and display applications, enhancing data
development efficiency by at least 50%; I performed data analysis and created custom visualizations by using Smart-BI.In one task, I Managed 13 custom Barra reports for predictive indicators (beta, tracking error, etc.), completing risk and factor attribution.
Then I automated regular report processing and imported into the company database using Python and Barra Portfolio Manager’s API. I employed MySQL for data cleaning and analysis, integrating charts in SmartBI for company’s quarterly risk reportsIn another task—IMA Custom Index: I Coordinated FTP and SQL Server using raw files from the index company to compile custom indices.
This internship gives me a new understanding of my future life plan, which is technology for finance. So I applied for the engineering position in Goldman Sachs.
