The invention relates to a packaging box, in particular to a combined stealing-disassembling-preventing packaging box. The packaging box comprises an outer box body defined by a bottom tray and a plurality of outer box plates; an inner box body is arranged inside the outer box body and is defined by a plurality of inner box plates; the inner box plates are in one-to-one correspondence with the outer box plates; a first bearing is fixed to each outer box plate in a penetrating manner and comprises a first bearing inner ring, a first clamping ring located between the corresponding inner box plate and the outer box plate is fixedly arranged on the first bearing inner ring, and a first bulge is arranged on the edge of the first clamping ring; a round groove matched with the corresponding firstclamping ring in shape is formed in each inner box plate, a first annular clamping groove for clamping the corresponding first bulge is formed in the groove bottom of the round groove, and a first clamping opening communicating with the first annular clamping groove and the round groove is formed in the edge of the round groove; the inner box plates are detachably hinged to the bottom tray; and the adjacent inner box plates are connected fixedly. The combined stealing-disassembling-preventing packaging box is provided, so that the probability that the packaging box is subjected to stealing-disassembly and opened without permission during transportation is reduced to a relatively large extent.

The invention discloses a cloud printing method, system and storage medium. The method of the present invention enhances the encryption level of the file through the three-party encryption of the cloud, the remote terminal and the printing terminal. The cloud sends the identity information, which is then forwarded to the printing terminal by the cloud. The cloud makes a preliminary judgment on the remote terminal, and then the printing terminal judges the secret level and identity information of the remote terminal to finally determine whether the printing terminal establishes a connection with the remote terminal. In addition, since the remote terminal only corresponds to one printing terminal, if the cloud receives feedback from more than one printing terminal in the process of broadcasting the identity information of the remote terminal, it can timely identify that there is a fake printing terminal in the network where the current printing terminal is located. Improve the security of the print terminal.

The embodiment of the present invention discloses an information transmission method, wherein the information transmission method is applied to a server, including: obtaining the sending information of the first terminal, encrypting the sending information, and generating an object code map, wherein the The sent information includes at least one of plaintext information, sensitive information, and secret information, and the object code map carries graphic encoding information and a digital signature of the graphic encoding information with the private key of the security code generation system, or the first Digitally signing the graphic encoding information with the terminal private key; returning the object code map to the first terminal, so that the first terminal sends the object code map to at least one corresponding second terminal. An information transmission method in an embodiment of the present invention realizes the improvement of security and privacy of information transmission.

The invention discloses a data separate storage and reduction key disk. The key disk comprises a USB control chip, a separation and reduction processing chip and a flash memory chip. The USB control chip receives and analyzes commands and data transmitted by a drive program through a USB port. The flash memory chip receives commands and data sent by the separation and reduction processing chip and stores the data. The separation and reduction processing chip is connected with the USB control chip and the flash memory chip and separates and reduces the data. An electronic document is separated step by step through the chips in the key disk, two data strings are generated finally, the two data strings are stored separately, a user can prevent the electronic document from being divulged just by ensuring the security of any data string, and therefore an effective document divulging prevention means is provided. The means has higher protection intensity than an existing security and secrecy system and is suitable for application and popularization.

The invention relates to a triple optical anti-counterfeiting ink with fluorescence, delayed fluorescence and room temperature phosphorescence, as well as an anti-counterfeiting method and an application thereof, which relate to the optical anti-counterfeiting ink. The anti-counterfeiting ink is composed of 1-5 parts of a nitrogen-enriched fluorescent carbon dot material, 720 to 880 of urea, 280 to 320 of biuret, and 25000 to 30000 of an organic solvent. The anti-counterfeiting method comprises: providing a triple optical anti-counterfeiting system having fluorescence, delayed fluorescence androom temperature phosphorescence; obtaining a fluorescent anti-counterfeiting mark under an excitation light source of 250-460 nm, the confidential information stored by the triple anti-counterfeiting ink and the interference information stored by the fluorescent anti-counterfeiting ink; after the excitation light source of 250-320 nm is turned off, obtaining the delayed fluorescent anti-counterfeiting mark, and displaying the confidential information; and after the excitation light source of 330-460 nm is turned off, obtaining the room temperature phosphorescent anti-counterfeiting mark, wherein the color thereof is obviously different from that of the delayed fluorescence. The anti-counterfeiting ink and anti-counterfeiting system are used in ink-jet printers, anti-counterfeiting marks,and information hiding.
