Embodiment Construction

[0033] The embodiments of the present invention will be described in detail below in conjunction with the above-mentioned drawings.

[0034] A speech tampering location detection method based on quantization characteristics. It is an in-depth study of the existing MP3 tampering location detection algorithm based on frame offset, and a new method is proposed to describe quantization features and perform tampering location detection.

[0035] The detection method involves the introduction of the MP3 encoding process and the introduction of the existing frame offset work, specifically:

[0036] MP3 encoding process

[0037] MP3 is a digital audio coding format with lossy compression. It can remove a large amount of redundant data information without affecting the voice content. In order to ensure the voice quality, according to the human psychoacoustic model, the voice details that most people cannot perceive remove.

[0038] The complete MP3 audio encoding process is as follow...

Abstract

The invention discloses a voice tampering positioning detection method based on a quantitative characteristic. The intensive study can be carried out based on the MP3 tampering position detection algorithm of the frame deviation of the prior art, and the updated detection method is provided for the description of the quantitative characteristic. By adopting the detection method, the frame deviation detection is not required, and then the complicated complexity caused by the frame deviation calculation can be prevented, and then the calculation complexity can be reduced greatly, and at the same time, the high bit rate condition of the inability of the frame deviation detection can be solved, and according to the experiment result, the detection method is provided with the higher detection accuracy.

Description

technical field [0001] The invention relates to a voice tampering location detection method, in particular to a voice tampering location detection method based on quantization characteristics. Background technique [0002] With the rapid development of digital technology and Internet technology, digital multimedia has been widely used in daily life. People generate a large amount of multimedia information every day, such as: use digital cameras to shoot videos, take photos, and voice chat. People can share these information with friends on the Internet through Internet technology, which enriches people's spiritual and cultural life and facilitates people The exchange and communication between people benefit from mastering new technologies. However, any technology has two sides. A large number of multimedia editing software can tamper with these digital information. If the tampered information is used illegally, it will bring a great threat to our life. Therefore, digital fo...
