The bank deposit certificate was found to be fraudulent one year later, and 200 million deposits disappeared, and the bank said it did not know

Hangzhou, December 7 (Reporter Zhou Yifan) According to the Voice of China "News Evening Peak" report, recently, a number of Zhejiang listeners reported to the Voice of China that about a year ago, they opened accounts in several rural credit cooperatives in Binzhou City, Shandong Province to deposit money, and after the expiration date, everyone went to prepare to withdraw the money, but the bank told that the deposit certificate was fake, and the deposits on the account were missing.　　Some users reported the case to the local police, and it is understood that the current problem of rural credit cooperatives in Binzhou City involves Bincheng District, Zouping County and Boxing County, with a total amount of more than 200 million. How did the deposit certificate become a fake for the card and the money deposited at the counter?

Digital watermarks are used in the field of information security

Digital watermarks are used in the field of information security

【Note】The tampering prompt watermark is mainly to detect the integrity and authenticity of the signal of the original file. The concealed logo watermark hides the important marks of confidential data and restricts the use of confidential data by illegal users.　　——Adopt content-based, non-cryptographic information hiding technology with digital watermarking as the core.　　——It has the characteristics of invisible information protection, covert management, invisible transmission, information encryption and decryption, and intelligent compression.　　- It is different from information encryption technology. Information encryption can only hide the content of confidential information, and cannot hide the existence of confidential information; And the digital watermark is the core of information camouflage, in the hidden machine

Research on image-based information hiding and information detection technology

Research on image-based information hiding and information detection technology

Information hiding and information detection technology is developed in the mid-to-late 90s of the 20th century as an emerging interdisciplinary discipline in the field of information security. The main research content of this paper is information hiding technology and information detection technology based on digital images. In this paper, the basic concepts and basic theories of image information hiding technology are analyzed and discussed, and a large-capacity LSB algorithm is designed on the basis of studying the existing information hiding algorithms. The algorithm combines the masking characteristics of the human visual system to block the image to adaptively embed secret information. The algorithm has good concealment and large hidden capacity. In order to

Research on information hiding technology based on CHIRP signal

Research on information hiding technology based on CHIRP signal

Digital watermarking technology is an emerging and effective digital cryptography technology to combat those serious illegal digital media communication behaviors. This technology can make up for the shortcomings of traditional encryption methods and make it a hot technology in the field of multimedia information copyright protection. In this paper, a time-frequency domain digital watermarking algorithm based on fractional order Fourier transform is proposed, and the watermark signal is a one-dimensional chirp signal, that is, a chirp signal. The embedding and detection of watermarks are in the time-frequency domain. Because the chirp signal exhibits pulsed characteristics in the FRFT domain as long as the order of the transformation is correct, it is only necessary to observe whether there is an impulse characteristic during detection

A simple and easy spatial domain image information hiding technology

A simple and easy spatial domain image information hiding technology

The watermark information is randomly added to each image block, rather than adding the watermark information to the image block described from top to bottom and left to right, for two main reasons: first, to prevent the attack may completely cut off the image part containing the watermark so that the watermark cannot be extracted, and to ensure that the watermark is not continuously cut when the image is cut, and the overview of the watermark image can also be observed from a visual point of view; Second, the random addition of watermark information that relies on the key is also considered from the perspective of watermark security.　　The implementation of random watermark embedding is as follows: let the size of the original image be M points × N points, by dense
