Background
In recent years, with the wide application of communication technology and the rapid development of mobile internet, the masses enjoy increasingly abundant material and cultural lives, but at the same time, with the help of informatization, telecom fraud has developed into a low-cost, high-efficiency, fine-division underground industry and is in a more and more intense trend. According to '2016 second quarter anti-telecommunication network fraud big data report' published by the public security department criminal investigation bureau and Tencent, 2015 year 59 ten thousand telecommunication fraud cases shared by the national public security department rise by 32.5 percent on the same scale, which causes 222 hundred million dollars of economic loss. Telecom fraud has become skin-cutting pain for the vast majority of the nation.
To address this problem, many internet enterprises such as Tencent, 360, Sao Gong, touch Bao, etc. have introduced terminal-based solutions. The current practice is that the called party installed with the relevant applications of the companies can mark the calling party as a fraud (harassment, promotion, express delivery, etc.) call and send the call to the server; thus, a database of user identifications is established on the server side; meanwhile, the called party sends the acquired calling number information to the server, the server returns a piece of information to the called party after comparison, and prompts that the calling number is marked as a fraud (harassment, promotion, express delivery and the like) call by the xxx people, so that the user can take precautions in time. This solution can certainly prevent fraudulent calls and the like to some extent, but has a certain limitation in practice.
Firstly, the terminal must install the relevant application to obtain the relevant label and reminder of a certain application;
second, existing applications do not have a system for annotating complaints and unmarking. If a normal private telephone is maliciously marked by a person, a complaint mechanism is not available, and the complaint mechanism cannot be timely relieved;
third, there is no method for judging fraudulent calls in time, and related applications usually need to notify users when obtaining labels of multiple users, so that the scheme is feasible, otherwise, in case of malicious labeling by one or two users, the call is not connected, so that more troubles are brought, and the effect of labeling may be delayed.

Wherein the terminals include terminals not having the anti-fraud application installed and terminals having the anti-fraud application installed.
The OSS server collects the short message content flowing through the data link in the data link of the telecommunication network, and sends the collected short message content to the marking server;
and the OSS server receives the probability that the short message content returned by the annotation server belongs to the fraud short message, and sends fraud-proof related annotation and prompt according to the probability of belonging to the fraud short message so as to prompt a terminal without the fraud-proof application or send the condition of belonging to other classified information so as to prompt the terminal with the fraud-proof application.
The mark server analyzes the short message to be received and returns the probability that the short message to be received belongs to a fraud short message and the condition that the short message belongs to other classification information, so that the OSS server sends related mark and prompt for fraud prevention to remind a terminal without a fraud prevention application, or the mark server sends the condition that the short message belongs to other classification information to the terminal with the fraud prevention application, so as to remind the terminal with the fraud prevention application, wherein the other classification information comprises at least one of harassment, promotion, express delivery and intermediary.
For convenience of explanation, the operation of the anti-telecom fraud system is realized as follows:
1. the calling party dials a call to the called party through the telecommunication network, and the OSS server or the terminal acquires the calling number information and sends the calling number information to the marking server;
the OSS server operates in an Operating Support System (os) of a telecommunication network, and the OSS is a comprehensive service operation and management platform and is also a comprehensive management platform that truly integrates a traditional IP data service and a mobile value-added service. The OSS is an integrated information resource sharing support system of telecommunication operators, mainly comprises parts such as network management, system management, charging, business, accounting and customer service, and the systems are organically integrated together through a unified information bus.
The marking server marks the calling number of a certain call which is spontaneously uploaded by a user as a server such as fraud, harassment, promotion, express delivery and the like;
2. the marking server analyzes the number, returns the probability of judging that the calling number is a fraud call to the OSS server, and sends the probability of belonging to the fraud call and the condition of belonging to other classified information (such as harassment, promotion, express delivery, intermediary and the like) to the terminal provided with the specific application software;
3. if the probability that the calling number is a fraud call is A level (energy level), the call is connected, and meanwhile, the OSS server sends short messages and voice prompts to the called user;
if the probability that the calling number is a fraud call is AA (possibly), the call is connected, and meanwhile, the OSS server sends short messages and voice prompts to the called user and gives a warning to the fraud suspicion call;
if the probability that the calling number is a fraud call is AAA level (most probable level), according to the severity, gradually increasing punishment, including directly interrupting the call, limiting the outgoing call, and even stopping the call;
the marking server sends the probability that the calling party belongs to the fraud call and the condition of other classified information (such as harassment, promotion, express delivery, intermediary and the like) to the terminal installed with the specific application software, and the called party can connect or reject the call after acquiring the relevant information.
In the embodiment of the invention, the beneficial effects are that on one hand, the called party can obtain the relevant anti-fraud label and reminder without installing application software, for example, the fixed-line telephone and the non-intelligent terminal can also obtain necessary reminder in the fraud incident process, the reminding mode of anti-telecommunication fraud is expanded, and the method is more beneficial to preventing telecommunication fraud and effectively treating fraud.
Example two
FIG. 2 is an implementation flow chart of an anti-telecommunication fraud method provided by the embodiment of the invention, which is suitable for an intelligent terminal installed with an anti-fraud application. The details are as follows:
s201, a called party connects a calling number and starts a call recording function;
s202, the called party finishes the conversation, and the recording file is sent to the marking server and marked as a fraud call;
s203, the annotation server randomly sends the sound recording file to a plurality of user identifications, receives scores of 0-5 given by the users, wherein the scores represent the probability that the calling number of the sound recording file is judged to be a fraud call by the users, the average score of the users is m, if the m is more than or equal to 3.5, the fraud call index is increased by 10, and if the m is not more than 3.5, the m is increased;
s204, when the fraud index is greater than or equal to 30, the annotation server judges that the calling number is class A fraud;
s205, when the fraud index is greater than or equal to 60, the annotation server judges that the calling number is AA type fraud;
s206, when the fraud index is greater than or equal to 120, the annotation server judges that the calling number is AAA fraud.
FIG. 3 is a flow chart of speeding up the determination that a phone number is a fraud phone, which is suitable for an intelligent terminal for anti-fraud applications, according to an embodiment of the present invention, and the related flow is detailed as follows:
1. the called party connects the call and starts the call recording function;
2. the called party finishes the conversation, and sends the recording file to the marking server and marks the recording file as a fraud call;
3. the method comprises the steps that a marking server randomly sends a recording file to a plurality of user identifications, receives scores of 0-5 given by a plurality of users, wherein the scores represent the probability that the users judge that a calling number of the recording file is a fraud call, and the average score of the users is m;
after receiving the sound recording files, a plurality of users judge the probability of being fraudulent calls and give a score of 0-5.
4. If m is more than or equal to 3.5 points, the fraud telephone index is increased by 10, otherwise, m is increased;
5. when the fraud index is 30, the marking server judges that the number is class A fraud; when the fraud index is 60, the marking server judges that the number is AA type fraud; when the fraud index is above 120, the marking server judges the number as an AAA type fraud.
It should be noted that the recording function should produce files that are encrypted, not tampered with and forged, and not easily compromised, and can only be decoded by a particular application.
Therefore, in the conventional mode, because malicious labels need to be prevented, the fraud telephone can be identified only by dozens of labels, the embodiment of the invention can identify the fraud telephone only by 3 calls at the fastest speed, greatly accelerates the exposure process of the fraud telephone number, reduces the time for judging the calling number as the fraud telephone, solves the problem that the fraud telephone is not judged in time in the prior art, and ensures that profit obtained through telecommunication fraud becomes a matter with legal risk and economic risk.
EXAMPLE III
FIG. 4 is a modified view of the notation of FIG. 3, with quantifiable data being used to estimate the probability that a phone labeled as a fraudulent phone is indeed a fraudulent phone, and the flow of the related process is detailed as follows:
the called party connects the call;
the called party finishes the conversation and marks as a fraud call;
if the called user is a real-name user, or the network access time exceeds 3 years, or the credit index exceeds a certain level, the fraud telephone index is + 1;
the called party provides a sound recording file, fraud index + 1.
In this embodiment, if the user who marks the number is real-name, or the number has long time to access the network, or has provided data that has proven reliable, or can provide direct evidence (such as a voice recording), or an authenticated volunteer, or has a high credit rating (using credit records of Tencent and Alibaca), the marked data should be considered to have higher credibility, and higher rating is given when quantification is performed.
Example four
FIG. 5 is a flowchart of an implementation of a white list mechanism provided by the method for anti-telecom fraud according to the embodiment of the present invention, which is detailed as follows:
the white list telephone fraud index is assigned an initial value of-1000;
white list phones are labeled;
a user of a white-list-labeled phone provided a recording?
If not, indicating that the secondary annotation is invalid,
if yes, the marking server randomly sends the sound recording files to a plurality of users for identification and scoring, and the average scoring value is calculated to be m;
determine if m is greater than or equal to 3.5? If yes, the mark is invalid, otherwise, the white list phone is marked by jumping to the step.
In this embodiment, a white list system for a phone is provided. For telephones listed in white lists of related departments of the country, regular authentication enterprises and the like, if credible direct evidence (such as voice recording approved by a large number of users) does not exist, the generated labels are uniformly invalid, so that criminals are prevented from maliciously labeling and touching fish.
EXAMPLE five
Fig. 6 is a flowchart of an implementation of the annotation removing mechanism according to an embodiment of the present invention, which is detailed as follows:
the network access time exceeds 3 years, or the credit index exceeds a certain level, and the fraud index is assigned with an initial value of-100;
the phone is labeled;
is the fraud index ≧ 30?
When the fraud index is more than or equal to 30, if the user receives a prompt that the user is possibly maliciously labeled, complaint label removal is carried out;
the marking server randomly sends the evidence reported in the past to a plurality of users for scoring, and the average value of the scoring is calculated to be m
Is m greater than or equal to 3.5? If yes, maintaining the original label, otherwise, judging whether m is less than or equal to 1;
if m is less than or equal to 1, the fraud index is assigned to-100, and if m is greater than 1, the fraud index is assigned to 0.
In this embodiment, if a normally used personal telephone with a normal number is maliciously labeled by a person, the labeling can be timely removed through a complaint mechanism, so that the problem that the prior art has no system for labeling complaints and removing labels is solved, and a user is reminded to prevent fraud and is guided to report. And the number which is beneficial to processing normal use is maliciously marked.
In addition, the longer the number is accessed to the network, or the higher the credit rating (credit records of Tencent and Alibara can be adopted), the more difficult the number is maliciously marked as a fraud phone, and the easier the number is unmarked, which is beneficial to preventing the number which is normally used from maliciously being marked.
