Faxing and monitoring method and device

Abstract

The invention discloses a faxing and monitoring method and device. The faxing and monitoring method comprises the steps that after monitoring is triggered, a monitoring center stores fax media; the monitoring center stops storing the fax media after monitoring is finished, the stored fax media are converted into fax images, the fax images are converted into text files, the text files are searched and matched according to preset fax sensitive content keywords, and the text files containing the fax sensitive content keywords are searched out. The fax images are converted into the text files, keywords searching is carried out on the text files, then the faxes containing sensitive word content is filtered out, the cost for artificially screening the faxes containing the sensitive content one by one is largely reduced for the national security department, and monitoring accuracy and work efficiency are improved.

Description

technical field [0001] The invention relates to legal interception technology in the communication field, in particular to a method and device for facsimile interception. Background technique [0002] With the constant changes in the international political situation and the domestic social security environment, fast and efficient legal interception is becoming more and more important, and the national security department has correspondingly put forward higher requirements for voice and fax interception technology. [0003] At present, the facsimile monitoring of the communication network generally adopts the following method, that is, after the fax monitoring call is triggered, firstly, the fax media is reported to the monitoring center through the network element, and then the monitoring center receives the media and saves it, and then the monitoring center decodes it according to the protocol encoding type. Call processing, and finally generate a fax picture file and save...

AI Technical Summary

Problems solved by technology

[0004] If the traffic volume of fax monitoring calls on the network element side is large, correspondingly more fax files will be saved on the monitoring center side, and as time goes by, more and more fax files will be accumulated. The search criteria are fax files containing sensitive text content, which need to be carefully checked and read by monitoring operators one by one to filter them out. Such an operation method obviously increases the workload of monitoring operators in the national security department and reduces monitoring efficiency.
