The invention discloses a method, a system and a device for internet data preservation. The method comprises the steps of obtaining to-be-preserved data submitted by a user and generating preservation verification information of the to-be-preserved data; generating storage electronic certificate information combination based on the to-be-preserved data and user information; sending a filing information combination including the preservation verification information, the storage electronic certificate information combination, user identification information and a preservation receipt code to an authentication server; obtaining a preservation electronic certificate which is generated and returned after the preservation verification information is filed successfully based on the filing information combination by the authentication server; and storing the to-be-preserved data, the storage electronic certification and the preservation electronic certificate. According to the method, the system and the device for internet data preservation, data issued by the user or obtained from the internet can be stored and preserved, the reliability of electronic evidences can be improved, and the electronic evidences can be stored and used conveniently.

This application discloses an information acquisition method and device. A specific implementation of the method includes: receiving operation information sent by terminals of multiple users; determining operation information sent by terminals of users belonging to the same user group in the operation information; and generating usage information based on the determined operation information. Realized sending different styles of applications to multiple user groups at the same time, ensuring high consistency of test conditions corresponding to users of multiple user groups, and effectively avoiding differences in page adoption by external conditions such as winter and summer vacations, holidays, etc. The impact of the analysis of the usage of the application of the style, and then effectively improve the authenticity and effectiveness of the analysis results obtained by analyzing the usage of the application of different styles adopted by the page. It only needs to release the version of the application once, and by sending the adjustment information to the terminal, a page with a new style is automatically generated, and the usage of the application with the new style is analyzed.

The embodiment of the present application discloses a block synchronization method, including: the first node device obtains the transaction block sent by the second node device, and the block header of the transaction block includes voting information and block headers of multiple core nodes Attribute parameters; detecting the legitimacy of the block header attribute parameters; determining the consensus result of the transaction block according to the voting information in the block header of the transaction block; if the block header attribute parameters are legal parameters, And the consensus result is a successful consensus result, then the transaction block is added to the transaction ledger corresponding to the first node device. By adopting this application, the authenticity and validity of synchronized blocks can be guaranteed, so as to improve the accuracy of business data.

The invention discloses a mobile terminal screen capture authentication method and system. The method comprises the following steps that when a mobile terminal detects a screen capture operation, a security authentication request message is sent to a security authentication platform; the security authentication platform forwards the security authentication request message to an SIM card, and the SIM card sends the security authentication request message to an authentication application for performing authentication; the authentication application analyzes the security authentication request message and prompts a user to perform confirmation; the authentication application receives a confirmation result, signs verification data, and sends a signature result and the confirmation result backto the security authentication platform; the security certification platform is used for carrying out signature verification on the signature result, and if the signature verification is passed and the confirmation result is confirmed, the security authentication platform signs and issues a certificate, generates a new signature picture, and returns an authentication success result to the mobile terminal; and the mobile terminal displays the new signature picture for the user to store or share. The authenticity and effectiveness of a screen capture picture of the mobile terminal in an open environment are improved, and the propagation of an internet information source can be effectively monitored and managed to a certain extent.

The invention discloses a method for checking the correlation degree of gas unit carbon emission data based on cumulative difference analysis. Firstly, the real-time monitoring data of the carbon emission concentration of the gas unit is converted into instantaneous carbon emission data, and then the gas unit intake gas is calculated by using the product difference analysis method. Finally, according to the size of the correlation coefficient, the rationality of the correlation degree between the carbon emission monitoring data is judged, and the abnormality of the carbon emission data is checked. The calculation logic of the method of the present invention is simple, and can be used for on-site on-line monitoring, find abnormal monitoring data in time, remind the on-site operators to troubleshoot data faults, and ensure the reliability of the carbon emission monitoring data of gas-fired units from the source; at the same time, it can be based on the update frequency of on-site monitoring data Reasonable selection of the length of the correlation coefficient time period not only satisfies the sample size requirements of the cumulative difference analysis, but also can be applied to different business scenarios such as online detection and early warning of abnormal data, data validity judgment, and parameter correlation analysis.

The invention discloses a preserved data authentication method, system and device. The method comprises the following steps: receiving a user's authentication request aiming at preserved data, generating inspection material data according to the authentication request and the preserved data aimed by the authentication request, sending the inspection material data and an evidence-saving data package corresponding to the preserved data to an authentication server, receiving an authentication report successfully generated and returned by the authentication server according to the inspection material data and the evidence-saving data package, and providing the authentication report to a user. An electronic evidence capable of being preserved by the user can be authenticated, reliability and availability of the electronic evidence are improved, and convenience is provided for preservation and usage of the electronic evidence.
