Information processing method and network security equipment

The invention discloses an information processing method and network security equipment, and relates to the technical field of information security, the information processing method comprises the following steps: step 1, information preprocessing: classifying information to be sent, classifying the information into various folders, and then summarizing; and step 2, information watermark processing: adding a watermark on the information file in a user-defined manner for identification processing. Ice blocks are added into an inner cavity of a heat preservation square barrel through a turning frame on the upper portion in advance, a fan body is controlled to work, air can be sucked from a conical hollow cover, then air flows through inner cavities of heat exchange square pipes and is cooled by the ice blocks, and then low-temperature air is conveyed into an inner cavity of a fixed protection frame through a heat dissipation pipe; original air in the inner cavity of the fixed protection frame is exchanged out t
