It puts forward higher requirements of system of legal protection of trade secrets. The protection of trade secret is faced with the following problems in current: it is harder to recognize the component elements and object scope of trade secrets, such as the secrecy,administration, expanded object scope; there is no regulation of data exchange and utilization to protect trade secret, such as lack of Data Protection Act, conflict of the transparency principle of data analysis and secrecy principle of trade secrets, threat from cross-border data storage; the abuse of standard terms in cloud service contract makes it easier for the trade secrets leakage risk; the abuse of government authority have negative impact on trade secrets protection.Legislation of trade secrets protection in most countries specifies following aspects: definition, the elements of constitution, identification of the infringement,burden of proof and so on.
