The invention discloses a dumb terminal security detection method and device, equipment and a readable storage medium. The method disclosed by the invention comprises the following steps of: acquiring network traffic data; determining a source end and a destination end of the network flow data; and if the source end is a dumb terminal and the destination end forbids the dumb terminal to access, giving an alarm. Visibly, according to the dumb terminal security detection method, after the source end and the destination end of the network flow data are determined on the basis of the network flow data, if the source end is the dumb terminal and the destination end forbids the access of the dumb terminal, then the situation indicates that the network flow data is abnormal access data, namely, the dumb terminal accesses the destination end forbidding the access of the dumb terminal, so that an alarm is given, therefore, the illegal behavior of the dumb terminal in the network can be sensed, and the safety of equipment in the network can be ensured. Correspondingly, the invention further provides the dumb terminal security detection device, the equipment and the readable storage medium, which also have the above technical effects.

The invention discloses a certification and key agreement method between devices. The certification and key agreement method between the devices comprises that the same key information records are pre-established in a primary device and a slave device; when the primary device determines whether the slave device possesses the same key serial number, the slave device generates a random number RA; the primary device and the slave device calculate result data A1, B1 and C1 according to the key information records and the random number RA of the primary device and the slave device; when the primary device determines that the calculated result data A1 and B1 is equal to the calculated data A1 and B1 of the slave device, the slave device generates a random number RB; the primary device and the slave device calculate result data A2, B2 and C2 according to the key information records, the result data C1 and the random number RB of the primary device and the slave device; when the primary device determines that the calculated result data A2 and B2 is respectively equal to the result data A2 and B2 calculated by the slave device, the key between the primary device and the slave device is C2. The certification and key agreement method between the devices is safe and reliable and is beneficial to guaranteeing safety and reliability of data interaction between devices.

The invention relates to a shared big data field protection platform, which comprises a depth-of-field identification device used for carrying out face feature analysis on a face object with the nearest depth of field in a morphologically processed image to determine whether the face object is an authorized user or not, and sending a first identification command when the face object is determinedto be the authorized user, otherwise, sending a second identification command; and a access control signal which is arranged in the desktop computer and is used for prohibiting access to the shared document address when the second identification command is received. The shared big data field protection platform is reasonable in design, safe and reliable. The face feature analysis is made on the face object with the nearest depth of field of the environment where a computer is located to determine whether the user is the authorized user or not, and when the user is determined to be the unauthorized user, the access to the currently requested shared document address is forbidden, so that the shared document content is prevented from being leaked.

The invention provides a traceless access controlling method and a device based on protection of a visual magnetic disc. The traceless access controlling method and the device based on protection of the visual magnetic disc are characterized in that a usbkey is used for setting up a visual magnetic disc in a system of a user terminal. A safety gateway device with a safety plug-in board is arranged between the user terminal and a web server. The usbkey is used for identifying a user identity by accessing a classified web system. The visual magnetic disc is mounted on the safety plug-in board to set up a visual accessing space. Files in the visual accessing space are oriented again to the visual magnetic disc. According to the traceless access controlling method and the device based on protection of the visual magnetic disc, only a user is allowed to access the files in the visual magnetic disc. Other progresses in the system are forbidden from accessing user files in the visual magnetic disc so that safety of the files in a transmission process is ensured and safety of local files of the user is ensured.
