One method of MBR de- coding is that the word lattice can be transformed into confusion network in order to achieve the recognition result with minimum WER.

To obtain recognition results with minimum word error rate in mandarin large vocabulary continuous speech recognition,a Chinese character confusion network algorithm is presented on the characteristics of Chinese language.

Prohibit Confusion——Determine the Underline of the Scope to the trademark right;

Court of first instance s judgment is that the defendant infringed the plaintiff s exclusive right of trademark and carried out unfair competition,whose theoretical basis is still traditional theory of confusion.

However, China still protects them from the theoretics of the confusion though it has strengthened the protecti.

The paper introduces existing code obfuscation technology first,then analyzes two popular obfuscation technologies named opaque and control flow flattening,and finally explores some open problems and research trends on obfuscation.

They take various obfuscation techniques to hide themselves in order not to be statically analyzed.

This paper describes a design idea of conditional branches-based software watermarking,and applies obfuscation and tamper-proofing technology to enhance watermark s robustness during the process of implementing.
