Problems solved by technology

The above-mentioned methods all need to install specific software or drivers on the computer, and have the following disadvantages: first, for some computers with confidential nature, they have higher authority, and it is not allowed to install external software, and if the software runs in a process injection mode, It is also easy to be mistakenly isolated by anti-virus software, resulting in monitoring failure; second, the method designed only for computer systems has certain limitations, and there will be compatibility problems under some POS machine systems, embedded systems, Linux and other systems

Embodiment 1

[0029] Such as figure 1 As shown, this embodiment includes N hosts and N USB printers, and a data acquisition module is correspondingly connected between each host and the corresponding USB printer, and the data acquisition module is connected to the host and the USB printer through a USB port. The host computer can be a personal PC, a print server or a POS machine.

[0030] Each data acquisition module is also equipped with a physical communication port, which can be an Ethernet interface, a serial bus interface, or a wireless interface such as wifi, bluetooth, etc. N data acquisition modules communicate with the same page restoration and content analysis module through their respective communication ports Connection, page restoration and content analysis module can be connected to application systems such as storage devices, PCs, local area networks or application servers.

[0031] The page restoration and content analysis module is a data analysis module that can dynamical...

Embodiment 2

[0033] Such as image 3 Shown, USB printer data monitoring analysis method comprises the following steps:

[0034] (1) Initialize each unit of the data acquisition module and the page restoration and content analysis module;

[0035] (2) The data acquisition module monitors the data transmission between the host computer and the USB printer;

[0036] (3) The page restore and content analysis module receives the data from the data acquisition module, the data includes the print page information and the USB printer information, first puts the print page information into the data buffer area, and sends the USB printer information directly to the printer simulation restoration unit , start the printer simulation restoration unit, restore and store the printed page information, and the page data analysis unit extracts valid information from the printed page according to the requirements of the application system.

[0037] (4) Repeat steps (2) to (3) to monitor and analyze the ent...

Abstract

The invention discloses a USB printer data monitoring analysis system and method. The system comprises a data acquisition module and a page restoring and content resolving module, wherein the data acquisition module is used for acquiring the data and commands sent by a host to a USB printer and transmitting the data and commands to the page restoring and content resolving module; and the page restoring and content resolving module resolves the data from the data acquisition module, distinguishes the printing page information from the USB printer information and starts a simulation restoring function to restore the printing page information. Without changing original printing connection relationship and without restriction of a monitoring platform, the system disclosed by the invention has the characteristics of independent work, unified application, convenience in deployment and the like and is suitable for the third-party supervision and information analysis.

Description

technical field [0001] The invention relates to the field of printing security, in particular to a USB printer data monitoring and analysis system and method. Background technique [0002] With the rapid development of printers, all walks of life in the market will basically be equipped with corresponding USB printers. From a security point of view, real-time monitoring of printing data can detect whether important commercial or personal information is leaked in time to ensure the safety of printing content. [0003] At present, the relevant printing monitoring technology mainly includes: 1. Deploying a specific monitoring program on the computer, and monitoring the printing data by monitoring the printing port when the program is running; 2. Installing a virtual printer device controller and driver on the computer, by virtual The printer first obtains the print request and the print page data information, so as to realize the monitoring of the print data. The above-mentio...
