Data Collection for Anti-Spoofing Tasks
Within a month, more than 10% of the entire database with over 2,000 photographs was collected
- Industry and use case:
- Facial identification solutions, Biometrics, Data Collection
- Data:
- 2,000 photographs 50 sets
- Project duration:
- 1 month
Task:
The client needed to collect data for biometric and anti-spoofing tasks. The required data were for four types of spoofing attacks: Live (live photo), Print (face image with background), Crop (face image without background), and Display (image from a phone/tablet screen).
Due to limited resources for finding performers and locations for data collection, the client sought a company to delegate this process to. After analyzing various parameters, they contacted Unidata.
Work Stages:
- Receiving the technical specifications
- Executing and approving the pilot
- Working on the first stage
- Two stages of validation
- Creating videos
- Discussing revisions
Solution:
Data collection was conducted through an extensive base of performers. The performers were tasked with taking five different photos of themselves. Each photograph had to maintain a specific distance, and the performer had to ensure proper positioning of their face in space.
Next, the validation and collection of images and videos of possible attacks took place. Some photographs needed to be printed on photo paper, while others required manually cutting out the background. The background had to remain identical, and each person’s photograph was checked for compliance with specified proportions.
Result:
More than 10% of the client’s entire database was collected within a month. 50 sets were collected, totaling 2,000 photographs.
“First and foremost, it was important for us to combine price, speed of order fulfillment, as well as expertise in biometrics and extensive data collection capabilities, which is why we chose you. We liked the process organization: after agreeing on the technical specifications, a pilot is conducted where iterations can be made.
Thanks to the collaboration, we were able to pass important testing. If we have any data collection tasks in the future, we will turn to the Unidata team again.”
