Abstract

The invention discloses an eavesdropping-proof recording method and an interference shielding device. The eavesdropping-proof recording method comprises steps: pre-acquired speech samples of a field person are encrypted, the encrypted speech samples are mixed, and mixed speech is obtained; and the voiceprint of the mixed speech is amplified to form interference speech and the interference speech is outputted. When the generated interference speech is played, although the decibel is not high, the interference speech can be acquired easily by various types of pickups (the type of the pickup is not restricted), interference to the field person is prevented, and interference shielding can be extremely effectively carried out on an eavesdropping-proof recording device.

Description

technical field [0001] The invention relates to the fields of acoustics and electromagnetics, in particular to an anti-eavesdropping recording method and an interference shielding device. Background technique [0002] Eavesdropping has a long history, and eavesdropping has been one of the main means for countries to steal secrets from ancient times to the present. Today, with the rapid development of science and technology, there are many high-tech eavesdropping devices, such as: wireless bugs, wired bugs, wall bugs, laser bugs, etc. With the development and progress of science and technology, the recording technology is very popular now, and there are many types of electronic devices with recording functions, such as professional digital recording pens, mini recorders, and mobile phone recordings. Not only that, the new generation of bugs can save audio files by recording first, and then send them to the stealer through the network. Nowadays, incidents of stealing state s...
