摘要：
The security of data is a message signal transformation allowing one to eliminate or considerably reduce a possibility of non-authorized access to transmitted data. A method is suggested for image signals transmission protection when great phase shifts are introduced in the assumed signal spectrum where time delay characteristic has complex character described by a piecewise-linear function, in difference from the known works. Such the characteristic makes it possible to create readings mixing.
