Fuente: Wipo "BigData" The embodiment of the invention provides an information safety processing method based on deep learning and big data and a cloud calculation system. The method comprises the steps: obtaining information safety access big data of a first access service interface and access safety situation big data on the first access service interface, and inputting the information safety access big data and the access safety situation big data into a first information safety risk learning unit; obtaining first safety risk confidence information output by the first information safety risk learning unit, and according to the first safety risk confidence information, determining a mode of accessing the safety risk confidence information from a first access source object in the access business service platform to a first access target object, the information safety access big data of the first access business interface and the access safety situation big data of the first access business interface are acquired from the access business service platform, and are input into the information safety risk learning unit, so that the safety risk confidence information is determined, and the precision of the safety risk confidence information is improved; therefore, the reliability of information safety maintenance is improved.
