![]() That seal also happened to be a listening device. This gift was a metal seal of the United States fixed to a wooden plaque. In 1945, Ambassador Harriman deployed to the USSR by America was given a gift by the Young Pioneer Organization in the Soviet Union. Today, militaries around the world use drones or spy satellites to capture footage, but pigeons were the original spy satellites.īoth World War 1 and 2 fostered a lot of imagination to create spy bugs throughout the world. As early as World War 1, military officials were strapping cameras to pigeons to take pictures overhead. Later pigeons themselves would become the spy bugs. On the off chance that a pigeon was caught, most people couldn’t read secret messages attached to them anyway because of the encryption methods mentioned above. Pigeons were one of the best original spy tools because they could reliably make their way back ‘home’ without being seen or captured. ![]() Militaries started to use pigeons to transport messages over long distances. Newer standards of encryption use prime numbers or more randomised numbers to create encryption that is much harder to break.Įven though humans became very good at being used as listening devices, there was always the issue of transporting secret messages back to the commanders and generals that needed them and vice-versa. Today we are more familiar with something like RSA encryption. In other words, it could be used multiple times to encode a message.Īs humans became better with math, so did encryption algorithms. The Caesar Cipher was stronger than the Alberti Cipher because it could better randomise those secret keys. This cipher is like the Alberti Cipher in that secret agents needed to match letters or symbols to other letters to decipher a secret code. Most people might recognise these as decoder rings.Īnother popular early encryption method was the Caesar Cipher. This cipher used a dial that you could spin to match one letter or symbol with another. Eventually, a chap by the name of Leon Battista created the Alberti Cipher. ![]() It could only transport small messages that were only a word or two long. Once that piece of cloth was wrapped around an object with a certain diameter, it would spell out words across that object. The Scytale is a simple piece of leather or ribbon with random letters written on it. One of the earliest forms of encryption was the Scytale. These messages were originally sent via encrypted messages. Once that information was collected, the spies would need to send that data back to their head office. This meant that people would have to take disguise and infiltrate an adversary to collect information. ![]() Before there were spy bugs, people had to perform that reconnaissance work. Of course, spies didn’t always have the luxury of small, electronic listening devices. These covert listening devices and spy bugs are real things! You can also go simpler with a flashlight, looking for any reflections from lenses that may be pointed in your direction.The history of spy tech and espionage is fascinating! We all loved our movies and television shows, like James Bond 007 or Get Smart, that featured spies with fancy gadgets like telephones hidden inside of shoes or watches that could listen to people from far away, but the truth is that these TV shows drew inspiration from the secret agent community. You can use visible light emitters, IR light emitters, or an infrared scanner. If you are looking for cameras that may have been planted in your home, there are a couple of options. Use this in conjunction with a radiofrequency scanner to detect microwave and laser beam transmission setups. Just be aware that non-electronic devices, like nails, can create false positives. These work to help you find semiconductor electronics. Depending on the detector that you use, you will either have a sound that gets louder as you get closer or you’ll have a graph of some sort as a visual indicator. If something is broadcasting a signal, it should be found. Turn your wireless devices off and then move the detector slowly and carefully around your home. Use a radiofrequency detector to scan for any transmitters. ![]()
