In above-mentioned network configuration, color ring server flow process of embed watermark information in color ring data is as shown in Figure 2, may further comprise the steps:
Wherein, original audio data is not for embedding the voice data of CRBT characteristic information.
Particularly, color ring server can embed identity code to each audio data section that segmentation obtains, and this identity code is used for the embedded location of mark watermark information, characteristics such as have that code length is short, autocorrelation is strong and computation complexity is low.The embodiment of the invention can select for use 13 Barker code 1111100110101} as a token of the sign indicating number.
In order to reduce the searching and computing amount of identity code, realize fast that synchronously color ring server can be embedded in identity code on the time-domain signal.For the robustness that improves detection and reduce the sense of hearing influence of identity code to primary signal; Color ring server can be searched for the discontinuous change point of voice attribute in audio data section; Such as the starting point of percussion music, chorus sound etc., and the discontinuous change point moment corresponding that will search as a token of the sign indicating number the embedding point.Wherein, voice attribute comprises at least a in tone, volume and the rhythm, and the method for searching for discontinuous change point comprises temporal analysis, frequency domain analysis method and time frequency analysis method.
Behind the embedding point of confirming identity code, color ring server can be embedded into identity code in the audio data section according to following formula from embedding the some beginning successively:
Wherein, S
i(j) be j sample point of the i section audio data segment of original audio data, B (j) is an identity code, and R is a constant, can get big value satisfying under the condition that identity code can not examine as far as possible, and mod is a modulo operation.
