NPL scientists develop ink to stop fake passports and currency notes

The Council of Scientific and Industrial Research (CSIR) and National Physical Laboratory (NPL) developed an ink to combat the problem of fake printing of passports and counterfeiting of currency notes. The ink has a new security feature o protecting itself against duplicity

Key facts of the discovery

The ink was produced based on single excitable dual emissive luminescent pigment. It was developed based on the concept of fluorescence and phosphorescence phenomena. Currently, the currency notes display only one color with the emission of wavelength. However, in the ink developed by the scientists features changes in pigment color after the notes are printed.

In ambient light, the ink shows white color. When the ink is exposed to UV light, it turns red and when the UV source is switched OFF it turns green.

Why the new ink?

According to the annual report of RBI (2018-19), the risk of duplication of Rs 500 and Rs 2000 notes is higher. The report says that recently launched 500 rupees notes are accounted for 121% of duplication and Rs 2000 notes are accounted for 21.9% duplication.

Fluorescence and Phosphorescence

Both in phosphorescence and fluorescence, the radiation is electromagnetic and is spontaneous.

In the case of fluorescence, the radiation stops after the source are switched off. On the other hand, in phosphorescence, the glow continues for a few hours.

Artificial intelligence Artificial intelligence (AI) is the simulation of human intelligence processes by machines, particularly computers. Typical applications of AI include expert systems natural language processing (NLP), speech recognition, machine vision and many more. AI programming focuses on three cognitive skills: learning, reasoning, and self-improvement. Learning process . This aspect of AI programming focuses on obtaining data and creating rules to convert data into actionable information. The rules called algorithms, provide computing devices with step-by-step instructions to accomplish a specific task . The process of reasoning. This aspect of AI programming focuses on choosing the right algorithm to reach the desired result. Processes of self-improvement. This aspect of AI programming is designed for consistently fine algorithms and ensures that they provide the most accurate results possible. Advantages and disadvantages of artific

5 Jobs that AI can replace in the next ten years

5 Jobs that AI can replace in the next ten years 1. Customer relationship advisor The emerging chatbots have redefined the experience of customer care. The probability of all telemarketing jobs getting replaced by AI is the highest. One of the major reasons behind this is efficiency. AI-enabled chatbots are considered more efficient than human resource-driven customer care services. 2. Programming language trainer All the IT firms employ a training consultant for various functions. The job of a programming language trainer is already on its way out. Employees prefer e-learning services over the human trainer. AI-driven interactive training solutions are likely to replace the job of programming language trainers. 3. Proofreaders There is nothing innovative about this job role. Almost all blogging sites use proofreading applications and software. There is a high probability that this job role will get completely removed in the coming future. Companies are developing self-che
