[0002] With economic development, people's material needs are constantly increasing. Many people seek a higher standard of living and wealth, and some users exploit this mentality to commit fraud. With the development of internet and communication technologies, telecommunications fraud methods have become more sophisticated and covert. Users can use the internet and communication technologies to commit fraud, making it easier to swindle victims' money. Telephone fraud is particularly prominent. Therefore, identifying fraudulent SIM cards and blacklisting them, while verifying genuine user numbers and adding them to the whitelist, is a crucial direction for combating telephone fraud. However, in the actual identification process, users often acquire SIM cards and impersonate others to commit fraud, greatly increasing the difficulty of number identification. Summary of the Invention

[0060] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] As an example, in telecommunications fraud, users often acquire SIM cards and impersonate others to commit fraud. Faced with this situation where "good people" turn into "bad people," it is difficult to identify and classify SIM cards into blacklists and whitelists from massive amounts of call records.

[0062] One of the core inventive points of this invention is that, in the process of identifying communication numbers, a reference communication number and at least one lower-level communication number corresponding to the reference communication number can be obtained. The reference communication number is the calling number. Then, with the reference communication number as the central node, a communication relationship network corresponding to the reference communication number can be constructed based on the calling and called party relationships between the reference communication number and the lower-level communication numbers. Then, the lower-level nodes in the communication relationship network, excluding the central node, are traversed from bottom to top to obtain the node information corresponding to each lower-level node. The node information represents the communication relationship between the lower-level node and the upper-level node, as well as the bridging relationship with the central node. The system first obtains information about the network, and then performs a credibility analysis on the lower-level nodes based on the node information to obtain the credibility results corresponding to the lower-level nodes. The credibility results include whether the communication number corresponding to the lower-level node is a trustworthy communication number or an untrustworthy communication number. By using a highly trustworthy communication number as the base communication number and obtaining the communication numbers associated with it, a communication relationship network is constructed. Then, credibility analysis is performed based on the node information corresponding to the lower-level nodes to realize the credibility analysis of the communication number of each lower-level node, thereby identifying trustworthy and untrustworthy communication numbers. Furthermore, untrustworthy communication numbers can be restricted based on the identification results to improve the security of network communication.

[0063] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, some technical features involved in the embodiments of the present invention are explained below:

[0064] A communication number can be an identifier used to represent a user's identity, including a mobile phone number, a virtual number bound to identity information, etc. In this embodiment of the invention, a mobile phone number is used as an example.

[0065] The basic communication number can be a highly reliable communication number, that is, a communication number that has been determined to be unlikely to be used by the user.

[0066] A communication relationship network is a network of different communication numbers built around communication numbers as nodes.

[0067] Reference Figure 1 The diagram illustrates a flowchart of a communication number processing method provided in an embodiment of the present invention, which may specifically include the following steps:

[0068] Step 101: Obtain a base communication number and at least one lower-level communication number corresponding to the base communication number, wherein the base communication number is the calling number;

[0069] In this embodiment of the invention, a reliable communication number can be obtained first as a base communication number, and then at least one subordinate communication number corresponding to the base communication number can be obtained. The base communication number can be used as the calling number to call the corresponding communication number. The subordinate communication number can include at least one first communication number located at the first layer that is called by the base communication number, and a second communication number located at the (n+1)th layer relative to the first communication number. The second communication number is the called number of the communication number at the upper layer, and n is a positive integer greater than 1 and less than 5.

[0070] In the specific implementation, after determining the base communication number, its corresponding first call detail record (CDR) can be obtained. Then, the communication numbers actively called by the base communication number recorded in the first CDR can be used as the next-level communication numbers. Then, the second CDR corresponding to the next-level communication number can be obtained, and the communication numbers actively called by the next-next-level communication number in the second CDR can be used as the next-next-next-level communication numbers. This process is repeated until the level of the next-level communication number is 7, at which point the acquisition of communication numbers ends, so that the corresponding communication relationship can be constructed based on these communication numbers.

[0071] For example, suppose that base communication number A actively calls communication number a. The call detail record (CDR) of communication number a records that it actively called communication number b. The CDR of communication number b records that it actively called communication number c. The CDR of communication number c records that it actively called communication number d. The CDR of communication number d records that it actively called communication number e. The CDR of communication number e records that it actively called communication number f. For communication numbers a, b, c, d, e, and f, their corresponding hierarchical levels increase sequentially.

[0072] It should be noted that, in this embodiment of the invention, seven levels are used as an example for illustrative purposes. It is understood that the levels can be adjusted according to actual needs.

[0073] Step 102: Using the reference communication number as the central node, construct a communication relationship network corresponding to the reference communication number based on the calling and called relationship between the reference communication number and the lower-level communication number;

[0074] In a practical implementation, a communication relationship network corresponding to the reference communication number can be constructed based on the calling and called relationship between the reference communication number and the first communication number, the calling and called relationship between the first communication number and the second communication number, and the calling and called relationship between the second communication numbers.

[0075] In one example, the communication numbers of highly trustworthy individuals are selected as the initial central node. Then, using this communication number as the first-level node, outgoing communication numbers are extracted from its corresponding call detail records (CDRs) as the second-level nodes. This process continues until the seventh-level node is reached. Then, based on the caller-caller relationship, a corresponding communication relationship network is constructed, with the central node as the initial node. The communication number corresponding to the higher-level node becomes the caller number of the communication number corresponding to the lower-level node. By constructing a communication relationship network corresponding to trustworthy communication numbers, a solid data foundation is established for subsequent credibility analysis of the communication numbers within this network. For example, refer to... Figure 2 The diagram illustrates a communication relationship network provided in an embodiment of the present invention. For a base communication number, it serves as a first-level node (i.e., a central node). A corresponding second-level node is constructed based on its corresponding call detail record (CDR), and so on, constructing several level nodes to obtain the communication relationship network corresponding to the base communication number. Correspondingly, the construction process for each central node is the same and will not be described in detail here.

[0076] Step 103: Traverse the lower-level nodes in the communication relationship network from bottom to top, except for the central node, and obtain the node information corresponding to each lower-level node. The node information is information that represents the communication relationship between the lower-level node and the upper-level node, as well as the bridging relationship with the central node.

[0077] In practical implementation, for a communication relationship network, besides the central node, the network can be traversed from bottom to top to obtain the node information corresponding to each lower-level node. This information is then used to perform credibility analysis on the lower-level nodes. The node information represents the communication relationship between lower-level nodes and higher-level nodes, as well as the bridging relationship with the central node. This information may include the call duration between lower-level and higher-level nodes, and the target bridging centrality between the lower-level and central nodes. Bridging centrality represents the shortest path from the lower-level node to the central node. For example, as described earlier, the bridging centralities for communication numbers a, b, c, d, e, and f are 1, 2, 3, 4, 5, and 6, respectively.

[0078] Step 104: Perform a credibility analysis on the lower-level node based on the node information to obtain a credibility result corresponding to the lower-level node. The credibility result includes whether the communication number corresponding to the lower-level node is a trusted communication number or an untrusted communication number.

[0079] In this embodiment of the invention, a directed network based on outgoing call behavior is established by pre-setting a highly trusted user as the central node of a one-mode network. A bridge is constructed based on call duration to establish connections. Then, the shortest paths from other nodes to the central node are used to calculate relationship weights, constructing a weighted network. Each node in this network is evaluated for its credibility, resulting in a credibility result for the corresponding communication number. If the result indicates a trusted communication number, it can be added to the corresponding whitelist; if the result indicates an untrusted communication number, its normal calls can be restricted. This process identifies trusted and untrusted communication numbers, allowing for restrictions on untrusted numbers based on the identification results, thereby improving network communication security.

[0080] In practical implementation, node information can at least include the call duration between lower-level nodes and higher-level nodes, as well as the target bridge centrality between lower-level nodes and the central node. The call duration and target bridge centrality can then be used to perform a credibility analysis on lower-level nodes, obtaining a corresponding credit score. If the credit score is greater than or equal to a preset threshold, the communication number corresponding to the lower-level node is considered a trusted communication number; if the credit score is less than the preset threshold, the communication number is considered an untrusted communication number. For example, the preset threshold can be set to 60, 70, or 80 points. When the credibility analysis shows that the credit score of the communication number corresponding to the lower-level node is greater than or equal to the preset threshold, it can be determined as a trusted communication number and added to the corresponding whitelist; when the credit score is less than the preset threshold, it can be determined as an untrusted communication number and added to the blacklist, restricting its normal calls and improving network communication security.

[0081] Specifically, for nodes in a communication relationship network, each lower-level node is connected to its upper-level node through a connection bridge. To calculate the credit score for each lower-level node, the following steps are taken: First, obtain the communication time threshold and the maximum bridging centrality (the communication time threshold can be a preset time threshold used to determine invalid communication; that is, when the communication duration between two communication numbers is less than the communication time threshold, the communication between them can be determined to be invalid; the maximum bridging centrality can be the path furthest from the central node). Then, the communication time threshold and call duration are weighted to obtain the credibility coefficient of the connection bridge corresponding to the lower-level node. Finally, the maximum bridging centrality, credibility coefficient, and target bridging centrality are used to perform credibility analysis on the lower-level node to obtain its corresponding credit score.

[0082] Optionally, in the process of assigning credibility scores to lower-level nodes, for a given lower-level node, there may be multiple communication links in the communication relationship network. The communication link with the shortest bridge centrality can be used as the target communication link (i.e., if a lower-level node has multiple bridge centralities, the smallest bridge centrality is used as the target bridge centrality). The target bridge centrality of the lower-level node in the target communication link is obtained, and then the corresponding credit score is calculated based on this target bridge centrality. If a lower-level node has at least two communication links with the same target bridge centrality in the communication relationship network (i.e., two communication links with the same and smallest bridge centrality), the difference between the credit scores corresponding to each communication link is used as the credit score corresponding to the lower-level node.

[0083] Furthermore, invalid communications can be removed from the communication relationship network. Specifically, lower-level nodes whose call duration is less than a preset communication time threshold can be removed from the network. For example, if the communication duration t1 between communication number a and communication number b is less than the preset threshold, then communication number b can be removed from the network. Similarly, if the communication duration t2 between communication number A and communication number a is less than the threshold, then communication number a can be removed. This allows for filtering of invalid communication numbers in the network based on call duration, reducing the burden of subsequent credibility analysis and improving the efficiency of number identification.

[0084] Optionally, untrusted communication numbers are removed from the communication relationship network, and the number of trusted communication numbers corresponding to each bridge centrality after removal is counted. This allows us to obtain the trusted communication numbers corresponding to the baseline communication number at different bridge centralities. Furthermore, even if a "good person" becomes a "bad person," trusted communication numbers can be effectively identified in the communication relationship network based on node information, thus effectively filtering out untrusted communication numbers and improving the security of network communication.

[0085] In this embodiment of the invention, during the identification of communication numbers, a base communication number and at least one lower-level communication number corresponding to the base communication number can be obtained. The base communication number is the calling number. Then, using the base communication number as the central node, a communication relationship network corresponding to the base communication number can be constructed based on the calling and called party relationships between the base communication number and the lower-level communication numbers. Then, the lower-level nodes in the communication relationship network, excluding the central node, are traversed from bottom to top to obtain the node information corresponding to each lower-level node. The node information represents the communication relationship between the lower-level node and the upper-level node, as well as the bridging relationship with the central node. Then, based on the node information, a credibility analysis is performed on the lower-level nodes to obtain the credibility results corresponding to the lower-level nodes. The credibility results include whether the communication number corresponding to the lower-level node is a trustworthy communication number or an untrustworthy communication number. By using a highly trustworthy communication number as the benchmark communication number and obtaining the communication numbers associated with it, a communication relationship network is constructed. Then, based on the node information corresponding to the lower-level nodes, a credibility analysis is performed to realize the credibility analysis of the communication number of each lower-level node, thereby identifying trustworthy and untrustworthy communication numbers. Furthermore, based on the identification results, untrustworthy communication numbers can be restricted to improve the security of network communication.

[0086] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, an example is provided below for illustration:

[0087] Step 1: Establish a pre-defined trusted user node (Spot) i

[0088] The card numbers of highly trustworthy individuals in society are selected as the initial central nodes.

[0089] Step 2: Construct the child node Node i

[0090] By filtering and analyzing the full call detail records, objects called from the previous node are obtained, and lower-level nodes (Nodes) are discovered and constructed. i Compared to calculating the total number M of nodes at each level. i .

[0091] Step 3: Construct a bridge connecting relationships i

[0092] By analyzing the calling and called party relationships in the communication behavior between upper and lower level nodes, a connection bridge is constructed. i Simultaneously, based on the communication duration (Time) in its call detail records, its Bridge is calculated. i Credibility coefficient K i .

[0093] Step 4: Construct a directed weighted relationship network

[0094] Construct the directed graph weighted relationship network as shown in i through the preset trusted user node Spot i , subordinate node Node i , connection relationship bridge Bridge i , and credibility coefficient K Figure 1 .

[0095] Step 5: Calculate the credit evaluation score Num of each node in the directed weighted relationship network i

[0096] For the trusted user node Spot i and subordinate node Node i , respectively count the credibility coefficient K i of their relationship bridge Bridge i , and the obtained features are as follows:

[0097] Node i -level: The shortest path from the current node Node i to the trusted user node Spot i in the directed weighted relationship network. <00​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​When applying it, it needs to be magnified 100 times for intuitive calculation.

[0105] Step Six: Filter Nodes from Bottom Up

[0106] Using a directed weighted relation network structure, nodes are selected layer by layer in a bottom-up manner. The specific rules are as follows:

[0107] Traverse the child nodes Node i Get the current node to the user node Spot i Shortest path Sp i If a node has multiple connections to a bridge i Generally, the minimum value Sp is taken. i As its Node i -level.

[0108] Step 7: Daily Data Statistics Iteration

[0109] Based on the nodes and network structure selected according to the rules in steps one through six, the credit rating score of each node is calculated daily, and its average value is calculated in the historical database. If a user node has no data updates for more than 7 days, it is removed from the number card whitelist. Simultaneously, the average credit rating score Num for each node is calculated. i The relevant level of it in the whitelist will be dynamically adjusted.

Those skilled in the art will understand that the electronic device structure involved in the embodiments of the present invention does not constitute a limitation on the electronic device. An electronic device may include more or fewer components than illustrated, or combine certain components, or have different component arrangements. In the embodiments of the present invention, the electronic device includes, but is not limited to, mobile phones, tablet computers, laptop computers, PDAs, in-vehicle terminals, wearable devices, and pedometers.

[0139] It should be understood that, in this embodiment of the invention, the radio frequency unit 401 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink data from the base station and processes it with the processor 410; additionally, it transmits uplink data to the base station. Typically, the radio frequency unit 401 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, etc. Furthermore, the radio frequency unit 401 can also communicate with networks and other devices through a wireless communication system.

[0140] The electronic device provides users with wireless broadband internet access through network module 402, such as helping users send and receive emails, browse web pages, and access streaming media.

[0141] The audio output unit 403 can convert audio data received by the radio frequency unit 401 or the network module 402 or stored in the memory 409 into audio signals and output them as sound. Furthermore, the audio output unit 403 can also provide audio output related to specific functions performed by the electronic device 400 (e.g., call signal reception sound, message reception sound, etc.). The audio output unit 403 includes a speaker, a buzzer, and a receiver, etc.

[0142] Input unit 404 is used to receive audio or video signals. Input unit 404 may include a graphics processing unit (GPU) 4041 and a microphone 4042. The GPU 4041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on display unit 406. The image frames processed by GPU 4041 can be stored in memory 409 (or other storage medium) or transmitted via radio frequency unit 401 or network module 402. Microphone 4042 can receive sound and process such sound into audio data. The processed audio data can be converted into a format that can be transmitted to a mobile communication base station via radio frequency unit 401 in telephone call mode.

[0143] The electronic device 400 also includes at least one sensor 405, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor. The ambient light sensor can adjust the brightness of the display panel 4061 according to the ambient light level, and the proximity sensor can turn off the display panel 4061 and / or backlight when the electronic device 400 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used to identify the posture of the electronic device (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. The sensor 405 may also include a fingerprint sensor, pressure sensor, iris sensor, molecular sensor, gyroscope, barometer, hygrometer, thermometer, infrared sensor, etc., which will not be described in detail here.

Specifically, user input unit 407 includes a touch panel 4071 and other input devices 4072. Touch panel 4071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 4071). Touch panel 4071 may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to the processor 410, which receives and executes commands from the processor 410. In addition, touch panel 4071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave.

[0146] Furthermore, the touch panel 4071 can cover the display panel 4061. When the touch panel 4071 detects a touch operation on or near it, it transmits the information to the processor 410 to determine the type of touch event. Subsequently, the processor 410 provides corresponding visual output on the display panel 4061 according to the type of touch event. It is understood that in one embodiment, the touch panel 4071 and the display panel 4061 are implemented as two independent components to realize the input and output functions of the electronic device.

By running or executing software programs and / or modules stored in the memory 409, and by calling data stored in the memory 409, it performs various functions and processes data, thereby providing overall monitoring of the electronic device. The processor 410 may include one or more processing units; preferably, the processor 410 may integrate an application processor and a modem processor. The application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 410.

[0150] The electronic device 400 may also include a power supply 411 (such as a battery) for supplying power to various components. Preferably, the power supply 411 can be logically connected to the processor 410 through a power management system, thereby enabling functions such as managing charging, discharging, and power consumption through the power management system.
