1 Introduction
"Authentication" has always been one of the important things in life in the digital age. How to use biometric information such as fingerprints, irises, and facial recognition to achieve personal account security authentication without resorting to passwords or other forms of physical interaction verification has become a hot topic for many IT companies and application entrepreneurs. Compared with traditional biometric authentication methods, applications based on biometric authentication are more secure, privacy-protected, reliable, and easier for users to recognize and accept.
With the popularity of smart phones and the emergence of various touch-screen electronic devices, more and more people choose to carry these new devices as personal computers, and use them as their main tools for work, study and entertainment. For users who adopt this technology, how to ensure the security of personal information is an important issue. Therefore, this article will provide readers with a simple and effective method - screen fingerprint unlock on iPad, which can help them access company resources, shop, pay bills, etc. more securely.
2. Explanation of basic concepts and terms
iPad screen fingerprint
Screen fingerprints are a set of descriptive fingerprint data formed by measuring the color and brightness distribution of each pixel, combined with the built-in camera of the device, to sample each screen area input by the user. This process is called the sampling process, and at the same time, keep the screen still during the whole process. By collecting the same paper fingerprint image, the same screen fingerprint data worn by different people can be obtained. Since each person's palm print is unique, the user's identity can be confirmed based on this data. Thanks to this confirmation step, relatively high security can be achieved.
TouchID (touch identification technology)
Touch ID is a fingerprint recognition technology introduced by Apple, which has been available as early as 2010. Touch ID can provide users with an additional layer of security to prevent break-in or theft. Touc
