The following will explain the caller end device, receiver end device and cloud server of a user data fingerprint verification operation provided by the present invention through implementations. However, these embodiments are not intended to limit the implementation of the present invention in any environment, application or method as described in these embodiments. Therefore, the description of the embodiments is only for the purpose of explaining the present invention, rather than limiting the scope of the present invention. It should be understood that, in the following embodiments and drawings, elements that are not directly related to the present invention have been omitted and are not shown, and the size of each element and the size ratio between the elements are only examples, and are not used to limit the present invention. The scope.

The first embodiment of the present invention is a user data fingerprint verification operation system 1, and its schematic diagram is depicted in FIG. 1. It should be understood that the user data fingerprint verification operating system 1 further includes a plurality of user devices connected to a cloud server, but the focus of the present invention is the "speaking end device", the "receiving end device" and the "cloud server" The mutual authentication operation between the two, so in Figure 1, only the "speaking end device", "receiving end device" and "cloud server" in the user data fingerprint verification operation system 1 are illustrated, and the others are not shown Other user devices that are not involved in this user data fingerprint verification operation. It should be noted that in the description of the present invention, when one of the user devices sends a communication request to another user device and wants to communicate, the present invention refers to the user device that sent the communication request as the "speaker device ", and the user device that receives the communication request is referred to as the "receiving device".

Next, the devices included in the user data fingerprint verification operating system 1 will be described. Please refer to Figure 1. The user data fingerprint verification operation system 1 includes a caller device 11, a receiver device 13 and a cloud server 15. The caller device 11 and the receiver device 13 are connected via the network and the cloud, respectively. The end server 15 is connected. It should be noted that these user devices (including: the caller device 11 and the receiver device 13) can be smart phones or other devices with basic communication and computing functions, and the cloud server 15 can be served by a third party The company provides, for example: application service providers, telecommunications service providers, etc. companies that have user device information. In some embodiments, the caller device 11 and the caller device 13 may only have a wireless communication channel when there is no data network.

It should be understood that FIG. 1 is only for illustration, and the present invention does not limit the number of caller end devices 11 and the number of caller end devices 13 included in the system for performing user data fingerprint verification operations. In other words, in other embodiments of the present invention, the system 1 for performing user data fingerprint verification operations may include one or more caller end devices 11 and one or more caller end devices 13 operating simultaneously, depending on the user data The fingerprint verification operation system 1 depends on the scale, and those with ordinary knowledge in the technical field to which the present invention pertains should be able to understand its content, so it will not be repeated.

The present invention mainly uses user data fingerprints to establish a verification mechanism. In order to facilitate understanding, the following paragraphs first describe the purpose and method of generating user data fingerprints. First, in order to verify each user device, the present invention needs to generate a set of spatially independent behavior identities, and pre-store the exclusive behavior identities of each user device, so that similar or similar behavior data can be used in the future. Determine whether the behavior data belongs to the same person/user device. Since the user data of each user device can better reflect the behavior characteristics of each user, and has unique and difficult to imitate characteristics, the present invention generates user data fingerprints by collecting user data of each user device. Later, the user data fingerprint is used to identify the legitimacy of the originating device that initiated the communication request.

Specifically, the user data fingerprint (Number FingerPrint; NFP) is Generated based on user data of each user device, and the user data includes one or a combination of a telephone user information, a call log, and a device information.

For example, the "phone user information" in the user data can include phone number, contact book, telecom name, app installed packages, number of notifications per day, and content of notifications Wait for information.

The "call log" in the user data can include call log, message log (SMS log) including event and content, display number, receiver report log, and Block log and other information.

The "device information" in the user data can include information such as battery log, device ID, model, and brand.

In this embodiment, user data fingerprints are mainly generated through destructive non-reversible decoding encoding processing (for example: Hash algorithm) and then assembled. Different encodings can be used for different types of user data. deal with.

Specifically, user data can be divided into static data that does not change (e.g. phone user information and device information) and dynamic data that may change (e.g. call history). Among them, static information can be obtained through a general message digest algorithm. (E.g. MD5 Message-Digest Algorithm) and cryptographic hash function algorithm (e.g. SHA-1 Secure Hash Algorithm) for encoding, and dynamic information can be encoded through artificial intelligence (AI) or machine learning (ML) ) Method to extract important features, generate digital feature information and then encode. Finally, these encoded data are combined into user data fingerprints. Those with ordinary knowledge in the technical field to which the present invention pertains should be able to understand the content of generating user data fingerprints through encoding processing, so it is not repeated.

In some embodiments, in order to enable the user device to have a connection relationship with the user himself. The cloud server 15 also provides users to bind users and numbers (such as SIM card numbers) to the user device through registration, number SMS verification, etc., and users can also log in to the user device through an account, so that the user’s User data, number, user device, and other information are integrated (that is, each number corresponds to a user data fingerprint). Therefore, the binding mechanism can further enhance the trust connection between the user device and the user, and can be used for the operation of the user device when verifying user behavior. Regarding the operation of the follow-up inspection user, I will elaborate on it later.

In this embodiment, the cloud server 15 pre-stores a plurality of user data fingerprints, and each user data fingerprint corresponds to one of the user devices. Specifically, the cloud server 15 may periodically receive each user data (for example, raw data about each user data) from each user device, and periodically according to each user The data generation corresponds to the user data fingerprint of each user device.

In some embodiments, each user device also stores its own user data, and also periodically generates user data fingerprints based on the user data. In addition, the cloud server 15 regularly checks/synchronizes with each user device based on the stored user data fingerprint. When the cloud server 15 finds the user data fingerprint of the user device and the use of the cloud server 15 When the difference degree of the fingerprint of the user data exceeds a certain threshold, a warning about the legality is issued. For example, when a user loses a mobile phone and is picked up by a stranger, the user data fingerprints generated by the user device will be different due to the different behavior characteristics, and the cloud server 15 will be able to use it through regular comparisons. The fingerprint of the user's data checks whether it meets the characteristics of the original user's behavior, and an immediate warning is issued to avoid unnecessary malicious behavior.

The following paragraphs will detail the operation of the system 1 for fingerprint verification of user data For details, please refer to Figure 1. In this embodiment, the calling device 11 and the calling device 13 can be connected via at least one communication method (for example, communication or data network), and both the calling device 11 and the calling device 13 execute a verification program ( Not shown). Specifically, the verification program can be provided by the aforementioned third-party service company (ie, application service providers, telecommunications service providers, etc. companies that have user device information), and each user device participating in the fingerprint verification operation of user data needs Pre-installed, the verification program is responsible for the operation of the cloud server 15.

First, the caller device 11 transmits a communication request 101 to the receiver device 13, and the communication request includes at least a display number. Specifically, the display number is the number that the caller end device 11 wants to display to the caller end device 13, for example, the phone number of the caller end device 11. Then, the caller device 11 needs to send the first data stream 103 to the cloud server 15 corresponding to the communication request 101 for subsequent identity verification through the cloud server 15, and the first data stream 103 includes at least a receiver number, for example : The telephone number of the receiving end device 13.

Subsequently, the cloud server 15 transmits the user data fingerprint 105 corresponding to the calling device 11 to the calling device 13 according to the receiving terminal number in the first data stream 103. Specifically, the cloud server 15 selects one of the user data fingerprints 105 corresponding to the originating end device 11 from the user data fingerprints, and corresponds to the user data fingerprint 105 of the originating end device 11 according to the receiver number. Transmit to the receiving end device 13.

Then, the receiving end device 13 will verify the authenticity of the display number through the cloud server 15. Specifically, the receiving end device 13 generates a second data stream 107 based on the display number and user data fingerprint 105, and sends the second data stream 107 to the cloud server 15 to query the display number and user Whether the data fingerprint 105 matches.

Subsequently, after receiving the second data stream 107, the cloud server 15 determines that the second data stream 107 Whether the display number in the stream 107 corresponds to the user data fingerprint 105. Specifically, if the cloud server 15 determines that the display number corresponds to the user data fingerprint 105, it means that the display number corresponds to the real number of the caller device 11. Conversely, if the display number cannot correspond to the user data fingerprint 105, it means that the display number provided by the caller device 11 is a forged number.

Then, after the cloud server 15 verifies the second data stream 107, a verification result 109 is generated, and the verification result 109 is sent to the receiving end device 13. The receiving end device 13 can determine the validity of the communication request 101 sent by the speaking end device 11 according to the verification result 109.

According to the aforementioned verification mechanism, when the caller device 11 maliciously forges the display number, through the verification operation of the caller device 13 and the cloud server 15, the caller device 13 can learn that the caller device 11 is sending abnormal communication. Request (that is, different from the display number corresponding to the originating device 11).

In some embodiments, the user data fingerprint stored in the cloud server 15 further corresponds to a bank account, and when the communication request 101 sent by the caller device 11 to the caller device 13 includes a bank account. The user data fingerprint verification operation system 1 further performs the following operations: the second data stream 107 sent by the receiver device 13 to the cloud server 15 further contains the bank account number, so that the cloud server 15 further verifies the second data stream Whether the bank account number contained in 107 corresponds to the user data fingerprint 105 to generate a verification result 109. Accordingly, the receiver device 13 can determine the legality of the number displayed in the communication request and the bank account number according to the verification result 109.

It can be seen from the above description that the system 1 (including the originating device, the receiving device and the cloud server) operating through the fingerprint verification of user data provided by this embodiment, sends a communication request to the receiving device by requesting the originating device to send a communication request to the receiving device Device, it needs to send a first data stream (which includes at least the receiver number) to the cloud server in response to the communication request, and the cloud server According to the receiving terminal number, a user data fingerprint corresponding to the calling terminal device is sent to the receiving terminal device, and the receiving terminal device transmits the second data stream containing the display number and the user data fingerprint to the cloud On the server, the cloud server verifies the second data stream to generate a verification result, and prevents malicious behaviors by third-party counterfeiters through a cooperative verification mechanism of three-party devices.

In the present invention, by continuously checking the behavior characteristics of the user’s device, the user’s behavior can be continuously grasped through the user’s data fingerprint while maintaining the user’s privacy (that is, sensitive biological information is stored on the user’s end). The behaviors between them can be passed through the trust transfer process of a third party (ie, cloud server) to ensure the trust value between users. In addition, the present invention further solves the problem that the conventional technology lacks the ability to verify the caller device and account information. Therefore, the present invention can accurately and efficiently verify the identity, and prevent the intentional person from performing malicious behaviors by forging identity and information.

For example: "First" and "Second" in the first data stream and the second data stream are only used to indicate different data streams.

In summary, the user data fingerprint verification operation technology provided by the present invention (including at least the caller device, receiver device and cloud server), by requesting the caller device to send a communication request to the receiver device, In response to the communication request, a first data stream (which includes at least the receiving terminal number) needs to be sent to the cloud server, and the cloud server then according to the receiving terminal number The code sends a user data fingerprint corresponding to the calling end device to the receiving end device, and the receiving end device sends the second data stream containing the display number and the user data fingerprint to the cloud server. The cloud server verifies the second data stream to generate a verification result, through a cooperative verification mechanism of three-party devices, thereby avoiding malicious behaviors by third-party counterfeiters.

In the present invention, by continuously checking the behavior characteristics of the user’s device, the user’s behavior can be continuously grasped through the user’s data fingerprint while maintaining the user’s privacy (that is, sensitive biological information is stored on the user’s end). The behaviors between them can be passed through the trust transfer process of a third party (ie, cloud server) to ensure the trust value between users. In addition, the present invention further solves the problem that the conventional technology lacks the ability to verify the caller device and account information. Therefore, the present invention can accurately and efficiently verify the identity, and prevent the intentional person from performing malicious behaviors by forging identity and information.

The above-mentioned embodiments are only used to exemplify part of the implementation aspects of the present invention and to explain the technical features of the present invention, and are not used to limit the protection scope and scope of the present invention. Any change or equal arrangement that can be easily accomplished by a person with ordinary knowledge in the technical field of the present invention belongs to the scope of the present invention, and the protection scope of the present invention is subject to the scope of the patent application.
