What is Face Blurring?

Deep learning systems are an essential part of our lives so that we can now use our faces to do many things, from unlocking our phones to finding missing people. The widespread use of camera technology in everyday life has resulted in today's reality, in which people's faces are frequently collected on a daily basis. The vast amount of data that these machine learning algorithms rely on is becoming increasingly private and sensitive. It also requires the protection of those people's privacy. As a result, data anonymization is one technique to comply with tough data privacy laws like the CCPA, APPI, CSL, and GDPR.

The GDPR clarifies, "Personal data shall be collected for specified, explicit and legitimate purposes and not further processed in a manner incompatible with those purposes." Numerous approaches for anonymizing visual data have been significantly developed. However, face blurring is the most effective and appropriate among these techniques. Face Blur allows businesses to share datasets with the outside world while maintaining their own privacy and the privacy of those in the photo or video. In this article, we will explain face blur for data privacy in deep learning and its importance.

Face Blur software detects faces in any real-time video stream or still image using deep learning technology. When a face is recognized, an additional layer of blurring or pixelation is added on top to conceal the face. This procedure is conducted without altering the video's quality, as the video's other features remain undamaged.

How Does it Work with Cameralyze?

Cameralyze Face Blurring Application

As shown above, you can create your own Face Blurring app in just 4 steps on the Cameralyze no-code platform. You can customize the first and last step according to your own preference. For example, for the first step, you can choose one of the various options such as CCTV, folder, and Webhook as the place to provide input to your application. As the place where you will save the application result, it is possible to choose applications such as Google Docs, Dropbox, and Zapier from third party integrations that are suitable for use on the platform instead of a folder.

Applications of Face Blur

Face blurring can be used for a variety of sectors that need to give access to video streams or share the output with third parties, such as security or analytics. As there is no limitation on the number of faces that can be blurred at one time, face blur software can be applied easily and effectively for various privacy issues. Here are some of the uses of face blur:

Identity and privacy protection in public and private spaces

Automatic face blurring technology to live video streams can be applied in public or private venues such as railway stations, airports, shopping malls, or privately-owned companies to ensure public privacy. You can check our latest automatic face blurring article from here.

Worker anonymity in industrial companies

For instance, it is possible to protect worker anonymity while streaming live video footage of regular office activities in action. In addition, it is your choice to turn on or off the face blurring feature whenever it is necessary.

Online safety for children

Understandably, many parents do not want their children's faces to be seen on the internet. To preserve their privacy, employing face blurring can be a good option.

Press photography and reporting

People can be required to sign various paperwork in photojournalism and news reporting to allow you to use their images in the media. Provided a person refuses to sign or a journalist does not have the opportunity to inquire, the photo can still be published if the faces are blurred.

Dataset and distribution of datasets

Datasets are crucial for deep learning and computer vision technologies. However, they include a mass number of human presence in them, which come with a problem: privacy issue. Face blur application can be a great solution for this problem. It is possible to have an effective way to apply privacy laws and keep these data undamaged at the same time.

The Importance of Data Privacy for People

Deep learning algorithms have become the core of emerging AI-based applications thanks to their exceptional accuracy. For this deep learning training and its accuracy, companies collect and store huge amounts of data. Deep learning, on the other hand, requires vast data collection, which inevitably raises privacy concerns. The corporations that gather personal, highly sensitive data such as images and videos store it permanently. Consumers are unable to remove data or limit the purposes for which it is utilized. However, such personal information may be exposed to legal issues. Face blurring is a technique for reducing the privacy risks associated with facial photographs and videos. You should consider using Face Blur for the privacy of customers because the collected data can be sensitive, causing harm if leaked. So it is necessary to keep private information secure as they are easily exploited for stalking, harassment, identity theft, or mass monitoring.

Why is Face Blurring Necessary for Data Privacy in DeepLearning?

As we explained to you why data privacy is important for people, we can now clarify why face blurring is necessary for data privacy in deep learning. The widespread use of smartphones, especially, allows millions of photographs to be posted to social media sites and shared on a daily basis. It is important to consider the privacy of those people and conceal their faces. Methods for concealing identification through data manipulation can be used to preserve people's privacy. Many strategies concentrate on the face since it is the most easily recognized feature. It can be thought that covering the face with an evenly colored rectangle works and erases all information about the face, ensuring that it can no longer be used to expose an individual's identity. However, this simple technique makes these significant pieces of information useless because deep learning requires a high level of utility preservation. Digital data may be utilized to learn more about customers in the retail industry and to spot unusual situations or unlawful behavior. So, it is important to choose the right method to reserve the utility of data. It would be appropriate to mention the importance of face blurring in deep learning here. Because thanks to the face blur app, it is possible to keep data utility for deep learning accuracy and to protect an individual's identity at the same time.
