The embodiment of the invention provides a method, device and system for releasing network information. The problems that the accuracy of releasing the network information is lowered, and the releasing effect is poor are solved. The method comprises the steps of receiving a network information scheduling request sent by a demand side platform, wherein the network information scheduling request comprises the corresponding cookie_1, of a user, in the demand side platform; seeking cookie_2 related to the cookie_1 in a prestored cookie association table; seeking user attributes corresponding to the cookie_2 in a pre-generated user attribute database; retrieving the corresponding network information in a network information base according to the user attributes and returning the network information to the demand side platform. According to the method, device and system for releasing the network information, user data collected through a data side can be fully utilized, the user-oriented network information can be accurately released, and the releasing effect is improved; the data privacy of all sides is fully protected, and the trust relationship of a whole industry chain is built.

The invention discloses an invoice true check system based on cloud computing and encrypted two-dimensional codes and belongs to a tax invoice true check system. The invoice true check system comprises a tax office cloud computing platform, an encrypted two-dimensional code device and an invoice scanning decrypting device. The tax office cloud computing platform is used for managing the encrypted two-dimensional code device and the invoice scanning decrypting device. The encrypted two-dimensional code device is used for printing the encrypted two-dimensional codes on physical invoices when invoicing invoices for drawers. The invoice scanning decrypting device is used for scanning, decrypting and comparing the invoices needing true check and outputting processing results according to grades to serve as true check basis. Compared with the prior art, the invoice true check system based on cloud computing and the encrypted two-dimensional codes can solve the problems of trust issue and data safety of the existing invoice true check results, and restrains invoice counterfeiting and false invoice using to a certain extent.

The invention discloses a microsatellite multiplex-PCR (Polymerase Chain Reaction) method for carrying out a paternity testing on crassostrea gigas. The microsatellite multiplex-PCR method comprises the following steps of extracting parent and offspring DNA (Deoxyribose Nucleic Acid); carrying out multiplex-PCR amplification on extracted DNA samples by using 18 microsatellite sites and M13 (-21) universal primers with fluorescent marks; detecting a fluorescent signal of an amplified product, and obtaining parent and offspring gene type data; carrying out genetic relationship identification on the parent and the offspring. The microsatellite multiplex-PCR method disclosed by the invention verifies that two groups of multiplex-PCR combinations are used for carrying out the paternity testing on 12 crassostrea gigas full-sib families, so that the identification success rate is up to 100 percent; a set of DNA mark-based paternity testing technology which is economic and effective and is high in accuracy is provided for the crassostrea gigas; by a genealogical relationship record obtained through microsatellite mark identification, producing places of individual crassostrea gigas can be traced back, so that a tracking and source tracing technology of crassostrea gigas products can be established, and powerful technical support can be provided for solving food safety problems which are increasingly concerned by people in nowadays society.
