Photo time, don't hold 2 inches. 🚨

Anyone who likes to take pictures and pretend to "Chu 2 inches" or Peace Sign may need to be more careful, because cybersecurity experts now warn that today's AI and high-resolution smartphone cameras can take ordinary photos to "fetch fingerprints" and may be used to forge identities in the future.

.

This trend began to be talked about heavily in China after Li Chang, a financial security expert, demonstrated through a television program that by taking a selfie with his fingertips clear enough, AI could enhance the contrast of fingerprints, even if the original image was blurred.

.

According to the report, if the image is taken at a distance of about 1.5 meters and the fingertips are facing the camera, there is a high chance that the system can extract fingerprint details, and images taken at a distance of 1.5 to 3 meters may also see some fingerprint information.

.

Although many parties consider it not an easy threat to the average user, experts agree that the AI technology of image adaptation is developing very quickly, reducing the cost and difficulty of extracting biomimetric data from photos.

.

A concern is that "fingerprints" are an irreplaceable biomimetic data, unlike a replaceable password. If the data is leaked, it may be used to unlock some kind of device, smartlock, or authentication system.

.

However, security researchers indicate that this attack also relies on high-quality images, clear angles, appropriate lighting, and may require multiple illustrations, so it is often a targeted attack rather than random hacking of ordinary users.

.

This is not the first time this has been warned, because back in 2017, Japanese researchers revealed that fingerprints could be read from photos taken about nine feet away.

.

Initially, experts suggest that if you have to post images to social media, you should avoid images that see fingertips too clearly, especially high-resolution images, or blur your fingerprints before posting to reduce the risk of biomimetric misuse.

... Read moreจากประสบการณ์ที่ผมได้อ่านและศึกษาเรื่องนี้ ทำให้ผมเริ่มเปลี่ยนพฤติกรรมเวลาถ่ายรูป โดยเฉพาะเมื่อถ่ายภาพเซลฟี่กับเพื่อนหรือตัวเองในท่าชู 2 นิ้ว ซึ่งเคยเป็นท่าโพสต์ยอดนิยมและดูน่ารัก แต่เมื่อรู้ว่าเทคโนโลยี AI สามารถใช้ภาพถ่ายดึงลายนิ้วมือแม้ภาพจะไม่คมชัดมากก็ได้ จึงตัดสินใจหลีกเลี่ยงท่านี้ ความน่ากังวลไม่ได้อยู่แค่ที่การถ่ายภาพทั่วไป แต่ยังหมายถึงการแชร์ภาพบนโซเชียลมีเดียที่เป็นสาธารณะ โดยเฉพาะภาพความละเอียดสูงซึ่งในบางครั้งเราอาจไม่ทันได้สังเกตว่าปลายนิ้วของเราชัดมาก ซึ่งหากถูกนำไปใช้ประโยชน์ในทางที่ผิดก็อาจทำให้ข้อมูลชีวมิติสำคัญอย่างลายนิ้วมือถูกโจมตีหรือปลอมแปลงตัวตนได้ จึงแนะนำให้ลองใช้เทคนิคง่ายๆ เช่น การถ่ายภาพในมุมที่ไม่เห็นปลายนิ้วชัดเจน หรือใช้แอปพลิเคชันแก้ไขภาพเพื่อเบลอหรือลบบริเวณนิ้วมือก่อนโพสต์ลงโซเชียล ซึ่งเป็นวิธีที่ช่วยลดความเสี่ยงได้ดีโดยไม่ทำให้ภาพดูแปลกแยก นอกจากนี้ อย่าลืมตรวจสอบแสงและระยะห่างเวลาถ่ายภาพ เพราะยิ่งถ่ายใกล้และชัด ก็ยิ่งมีโอกาสข้อมูลลายนิ้วมือถูกดึงออกมาได้ง่ายขึ้น สำหรับใครที่สนใจเรื่องความเป็นส่วนตัวและความปลอดภัยไซเบอร์ การรับรู้ถึงความเสี่ยงของเทคโนโลยี AI กับภาพถ่ายจึงเป็นสิ่งสำคัญที่ควรติดตาม และปรับเปลี่ยนพฤติกรรมการแชร์ข้อมูลในโลกออนไลน์ให้เหมาะสมเพื่อปกป้องตัวเองจากภัยสมัยใหม่ที่ไม่คาดคิดนี้
