Problems solved by technology

Although this encryption method effectively protects the interests of font manufacturers, it cannot effectively monitor the output device, nor can it judge which output device the output is output from by comparing the output results. Some people with ulterior motives will not be able to play the role of security

Embodiment approach

[0028] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is introduced as follows:

[0029] Such as figure 1As shown, a method and system for encrypting and identifying an output device, the system is composed of a front-end input device and a back-end output device, the output device has a unique serial number, and both the input device and the output device are equipped with a safe font; the safe font It is divided into two types: front-end and back-end. The front-end font uses a standard TrueType font without encryption. It is installed on the computer and cooperates with the driver to realize the mapping of the front-end and back-end fonts. The encrypted PostScript font is installed on the output device; the PostScript font has good security, and the font of each output device is dedicated and difficult to copy, even if it is copied to other output devices, it cannot be used. The PostScript font library also has the character...

Abstract

The invention relates to an output equipment encryption and identification method and system, which comprises a front end input device and a rear end output equipment, wherein the output unit has a unique sequence number, while the encryption and identification method includes installing safety fonts into the input equipment and the output equipment. The beneficial result of the invention is that, it can accomplish the effective monitoring and control for the output equipment, in particular those for the special industries, or the special-purpose output equipment.

Description

technical field [0001] The invention belongs to the technical field of output device monitoring, and in particular relates to a method and system for encrypting and identifying output devices. Background technique [0002] At present, the usual output methods and systems are to make or edit electronic documents such as pictures and texts through processing devices such as computers, and then browse or print through output devices such as computer monitors or printers. This output method and system solves the problem of outputting electronic documents, and these processing devices and output devices are common. However, another problem also arises at the same time, that is, how to strengthen the supervision and management of certain output devices, especially the supervision and management of those special output devices used in specific industries or specific purposes. [0003] To process texts in various languages ​​by computer, it is necessary to encode the texts in vario...
