Description

Technical Field

[0001] The present invention relates to the technical field of file information entry encryption, and in particular to an encryption system for OFD format file information entry. Background Art

[0002] OFD (Open Fixed-layout Document) is a national standard for layout documents developed by the layout writing group established by the China Electronics Standardization Institute under the leadership of the Software Department of the Ministry of Industry and Information Technology. It is an independent format in China to facilitate the storage, reading and editing of electronic documents. When entering the information of the OFD layout file, an encryption system is required to avoid information leakage.

[0003] When using the encryption system, the operator needs to log in to the system and then enter the information. However, the existing encryption system can only encrypt the entered information. When the operator logs in to the system, it does not have the function of identifying and verifying the operator's identity. The function is single, which will lead to information leakage during the entry process. Therefore, it needs to be improved.

[0004] For this reason, it is necessary to invent an encryption system for inputting OFD format file information. Summary of the invention

Two magnets 38 are fixedly sleeved on the outside of the moving rod 31. An iron ring 39 is fixedly connected to the rear side of the shell 23. The iron ring 39 is sleeved on the outside of the moving rod 31. The box 29, the box 33, the piston 30, the piston 34, the moving rod 31, the moving rod 35 and other components are designed. The behavior monitoring module 16 can make the camera 24 move up and down when in use, so that the camera 24 can be lifted out of the shell 23 when in use, and the camera 24 can be moved back into the camera 24 when not in use, thereby avoiding the camera 24 being exposed to the air all the time.

[0057] The use process of the present invention is as follows: when using the present invention, the operator logs in to the system, and the user identity confirmation module 2 can verify the identity information of the operator when logging in. During the verification process, the user name verification module 3 can verify the login user name of the operator, and the biometric feature verification module 4 can verify the biometric feature of the operator, and the biometric feature includes face, body and iris. The password verification module 5 can verify the login password of the operator, and the password verification module 6 can verify the login password of the operator. At the same time, the authority identification module 7 can identify and determine whether the operator has the authority to enter after the operator's identity information is confirmed. When there is no entry authority, the intelligent alarm module 8 can alarm to prevent people who do not have the entry authority from entering, thereby preventing information leakage;

[0058] Then the operator can input information through the information input module 1. When inputting information, the information encryption module 9 can encrypt the input information. When encrypting, the sensitive information hiding module 10 can hide the sensitive information in the information. The information conversion module 11 can convert the plain text of the information into cipher text. Then the encrypted information is transmitted to the file storage library 14 by the intelligent transmission module 13, so that the file storage library 14 can store the information.

[0059] During the input process, the behavior monitoring module 16 can monitor the input behavior of the operator in real time when the operator inputs information to avoid suspicious information leakage, and the integrity detection module 17 can detect the integrity of the information when the operator inputs information to avoid missing information. In addition, an operation recording module 18 is designed to record the entire input operation of the operator. When recording, the login start time recording module 19 can record the start time of the operator logging into the system. The operation time recording module 20 is used to record the start time of the operator's input, and then compare it with the time recorded by the login start time recording module 19 to see whether the difference between the two times is large, so as to determine whether the operator exits the encryption system in time when the information input is completed. The operation type recording module 21 can record what operations the operator performs when inputting, including deletion and replacement, and the operation content recording module 22 can record what content the operator deletes and replaces when inputting, so that the operator's input operation can be monitored and recorded in real time, which is convenient for later review;

[0060] When the entered information needs to be retrieved from the file repository 14 at a later stage, the retriever applies through the information retrieval module 15, and then the user identity confirmation module 2 verifies the identity of the retriever. At the same time, the authority identification module 7 can identify and determine whether the retriever has the authority to retrieve. If the retriever does not have the authority, the intelligent alarm module 8 will alarm. If the retriever has the authority, the information retrieval module 15 can retrieve the information from the file repository 14. At the same time, the key for displaying sensitive information and converting ciphertext into plaintext can be obtained from the key management module 12, so that the complete information can be seen;

[0061] When in use, the behavior monitoring module 16 pushes the push block 32 forward, so that the moving rod 1 31 and the piston 1 30 can move forward, and then the air in the box 1 29 can enter the four box 2s under the action of the two pipes 1 36 and the four pipes 2 37, so that the four pistons 2 34 and the four moving rods 2 35 can move upward, so that the cover plate 25 moves upward, so that the camera 24 can move upward, and then the camera 24 can be lifted out of the shell 23, and then the operator's input behavior can be monitored;

[0062] When the moving rod 1 31 moves forward, the magnet 38 on the rear side can be attracted to the iron ring 39, thereby preventing the piston 1 30 from moving backward, and further preventing the air in the box 2 33 from returning to the box 1 29, so as to ensure that the state of the camera 24 does not change;

[0063] When use is finished, pull the pull block backwards, so that the piston 1 30 can move backwards, thereby sucking back the air in the four box bodies 2 33, so that the piston 2 34, the moving rod 2 35, the cover 25 and the camera 24 can move downwards, so that the camera 24 can be moved back into the camera 24 when not in use, thereby preventing the camera 24 from being exposed to the air all the time, and preventing dust from adhering to the camera 24 when used for a long time.

[0064] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the above technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention belongs to the scope of protection claimed by the present invention.
