News of market small network, in daily life, everybody always can get sundry rubbish short message, still can be deceived carelessly a bit, suffering letting a person can'ts bear character, but the method with cannot find good again comes screen these rubbish short messages.
The illegal behavior of bilk of short message of bogus radical station and purloin individual information is increasingly rampant, its equipment basically is comprised by lead plane and notebook computer, through the short message group hair implement, the relevant equipment such as machine of short message post a letter can search is taken it is the mobile phone inside limits of center, certain radius with its information, through pretending operation business radical stands, random is risked send bilk, advertisement to promote to user mobile phone forcibly with number of other mobile phone wait for short information.
But existing short message identifies the method belongs to public service orgnaization very likely because of forged number and be considered as Bai Ming sheet, thereby cannot effective identifying gives bilk short message, also cannot screen this kind of short message, accordingly, be badly in need of information of a kind of significant test and verify the method of lawful sex, prevent an user by illegal information becloud.
China to offerred a kind of more accurate means of settlement with respect to this problem.
The method shows 1 times like the graph:
Graph 1
Graph 2
Graph 2 in include in shows communication system base station, terminal unit, the first server and the 2nd server. The first server can be passed base what news has between station and terminal unit is alternant, and terminal unit and can simplify through the 2nd server between the first server both between alternant.
Graph 3
Above all, RF circuit 110 receive base the short message that the station sends, whether is 170 judgement short message processor target kind short message, 170 pairs of short messages have processor here Hash processing, through Ha Xi computation gets Ha Xi is worth 1, the first server marks mediumly according to information of test and verify information, go out to whether have the short message that sends this terminal unit certainly, go out to did not give this terminal unit certainly when tripartite server when sending a short message, the short message that the first server can decide to terminal unit is received directly is illegimate.
Next, when basis of the first server label information goes out certainly when having the short message that sends this terminal unit, the first server undertakes breathing out hoping to calculate getting Ha Xi is worth to this short message 2. Later, the first server is worth Ha Xi 2 be worth with Ha Xi 1 undertake comparing is opposite, if Ha Xi is worth 2 with haing rare value 1 photograph matchs, the short message that affirms terminal unit is received originates really this the first server, namely the short message that terminal unit receives is lawful short message.
Finally, demonstrating unit 130 on the report information that shows whether this short message is rubbish short message, the information that assures terminal unit is safe, prevent an user by con.
Can prevent the reception of rubbish short message effectively so, also avoided the possibility that be deceived.
