Invisible ink is a type of ink or coating that is colorless and undetectable when applied to the surface, but can be revealed by a number of processes. The use of invisible ink dates back to the Roman Empire, when juice from the invisible ink plant was used to write secret messages.
Today, there are many different types of invisible inks available. The most common is leuco dye ink, which is mixed with a chemical developer to create a visible image on the page. When mixed with the developer, an oxidizing compound is created which causes the dye to change color.
Other ways of using invisible ink include using ultraviolet light to reveal the words, using a black light, using a heat source like a lighter to cause the image to appear, or using a chemical reaction between the ink and another element, like flour.
Some invisible inks are made from stamps or laser-printed patterns onto a special paper and then treated with a special solution to make them appear as a hidden image.
When using invisible ink for security purposes, it is important to remember that the revealed message can be seen by anyone with access to the same methods of revealing the message. As such, it is best used for messages that do not require absolute secrecy.

These services generate a one-time number that you can use to text or call somebody and, once it’s done, they can’t track the number back to you. Finally, if you prefer using your regular device, you can use a messaging service that provides privacy controls, like Apple’s iMessage.
The app has an option for “Send as Invisible Text”, which does not add a delivery read receipt or show your name. Of course, the safety of your data and messages should always come first, so make sure you take all the necessary steps to protect your privacy and security.

How can I hide text messages from my wife?
The best way to hide text messages from your wife is to use an app or service that provides end-to-end encryption. End-to-end encryption ensures that only the sender and receiver of the messages have access to the content of the messages.
This means that even the messaging service provider cannot access the content, which makes it much more difficult for anyone other than you and your intended recipient to read the messages. Popular apps that offer end-to-end encryption include WhatsApp, Telegram, and Signal.
It’s also a good idea to create a separate phone account that only you have access to, to ensure that your wife does not have access to your messages. Additionally, make sure to delete any incriminating messages and clear the app’s history to ensure that your activity is not being recorded.
