摘要： The present disclosure provides a new Internet virtual data center system and a method for constructing the same. The new Internet virtual data center system includes: an Internet data explorer to sample and estimate Internet data to generate a data resource distribution map, the data resource distribution map reflects attribute information of Internet data; an Internet virtual resource library to store data resource distribution map and sample data collected by the Internet data explorer; a data resource distribution map management module to manage data resource distribution map; and a data resource guidance service module to generate and provide guidance service for data collection and mining of a data demander according to data resource distribution map. The present disclosure overcomes the blindness and disorder of the big data collection and development of the existing data centers, and avoids waste of resources and energy.

摘要： System and methods for performing behavior consistency verification are described. The method may include receiving user behavior data containing user activities performed during electronic transactions. The method may include retrieving expected behavior data corresponding to the user behavior data. The method may include generating a behavior consistency measurement based on the user behavior data and the expected behavior data. The method may further include transmitting the behavior consistency measurement in response to the receiving of the user behavior data. The behavior consistency measurement indicates a degree of consistency between the user behavior data and the expected behavior data.

摘要： The present invention discloses a method and system configured for monitoring and verifying software behavior, comprising: receiving, by a software behavior verification system based on a physical hardware system, legal user behavior data containing user activities performed during legal electronic transactions and storing the legal user behavior data as a software behavior model; monitoring, by a software behavior monitor, data packets transmitted in a transaction, and sending data packets to the software behavior verification system; retrieving, by the behavior verification system, expected key sequences and information in the data packets; comparing the key sequences and information retrieved from the data packets with that of the software behavior model; if the key sequences and information retrieved from the data packets does not consistence with the software behavior model, it is determined that the transaction is an illegal electronic transactions, and the transaction is closed.

摘要： Disclosed is a method for authenticating network transaction. The method comprises receiving, by an authentication center, a real-time user behavior during an electronic transaction; receiving, by the authentication center, a software behavior during the electronic transaction; performing, by the authentication center, a user verification of the real-time user behavior by comparing with a user behavior certificate maintained by the authentication center; performing, by the authentication center, a software verification of the software behavior by comparing with a software behavior certificate maintained by the authentication center; in response to a determination that the user verification fails or the software verification fails, terminating, by the authentication center, the electronic transaction.

摘要： System and methods for performing behavior evaluation based on an immunity system is provided. A method may include receiving historical behavior data containing user activities performed in an electronic transaction. The method may include extracting normal transaction sequences and abnormal transaction sequences from the historical behavior data. The method may include storing the normal transaction sequences into a normal transaction library and the abnormal transaction sequences into an abnormal transaction library. The method may further include, in response to receiving a current behavior data, extracting a current transaction sequence from the current behavior data, and in response to a successful matching comparison of the current transaction sequence with an abnormal transaction sequence in the abnormal transaction library, transmitting a first abnormal evaluation result as a response to the receiving of the current behavior data.

摘要： The present invention relates to a software behavior monitoring and verification system, which is composed of three parts including a software behavior certificate, a three-party software behavior monitor, and a real-time software behavior verification system. The software behavior certificate is formed according to three-party communications data packets in a correct transaction process among a user, an E-Commerce website, and a third-party payment platform; the three-party software behavior monitor is a data packet monitor installed on the E-Commerce website, the third-party payment platform, and the user client; after receiving data packets of interaction information in the transaction that are respectively submitted by the three-party monitor, the real-time software behavior verification system extracts and integrates key sequences and information in the data packets, and compares a user behavior interaction sequence with the software behavior model in real time according to a global unique order number, and sends an alarm and terminates the transaction in the case of illegal behaviors such as disorder and identity spoofing. By using key parameters such as URL exchanged among the three parties, a legal normal interaction process in the transaction of the three parties is defined, and a software behavior certificate is provided.
