Development of new golden security ink to protect confidential Indian passport data | Indian Science and Technology News | India Science Portal Say what is the current state of science and technology in India

Researchers at India’s National Institute of Physics, Science and Industry Research (CSIR-NPL), the Ministry of Science and Technology, have developed a new security ink that encrypts and protects sensitive data contained in documents such as passports.magazine scientificIndian naturereported on April 25.

Current security inks are unstable, lose their ability to emit light over time, and are mostly made from toxic substances. So a research team led by Bipin Kumar Gupta combined a variety of luminescent materials with specific magnetic nanoparticles to synthesize a safe and effective security ink.

Items printed with the newly developed security ink normally only look golden, but when exposed to ultraviolet light, they emit red and green light, and when exposed to a laser, they emits blue light. The magnetic nanoparticles in the ink also have a magnetic character recognition function, so confidential and personal data contained in documents such as passports and bank checks can be encrypted and protected.

The researchers also used the ink to develop a special QR code that is colorless under visible light, but can scan data under ultraviolet and laser light. In the future, the ink is also being considered for use in other areas, such as military equipment and pharmaceuticals, to curb fraudulent activities.
