Description

Technical Field

[0001] The present application relates to the field of data security technology, and in particular to advertising delivery methods, devices, equipment, storage media and products. Background Art

[0002] With the development of the Internet, advertising has become an important means of corporate marketing. When companies with high-value data resources connect with advertising media to achieve accurate advertising, the data source often uses mobile phone numbers or device numbers as user primary keys, while data resource companies can only identify anonymous IDs (Identity Documents) as user primary keys. When one party initiates a data query request through inadvertent transmission, the queried party cannot determine which of its data is called by the other party, and it is difficult to grasp the data call situation. If the querying party obtains data multiple times and performs reverse reasoning, it is possible to decrypt the confidential information owned by the queried party, which poses a risk of information leakage.

[0003] The above contents are only used to assist in understanding the technical solution of the present invention and do not constitute an admission that the above contents are prior art. Summary of the invention

[0015] Based on the correspondence between the virtual identification number and the strategy identification number, determining a matching virtual identification number that meets the delivery strategy corresponding to the strategy identification number from the virtual identification number;

[0016] Based on the address query result corresponding to the matching virtual identification number, the matching address information that complies with the delivery strategy corresponding to the strategy identification number is determined.

[0017] In one embodiment, before the step of initiating an anonymous query request to the operator based on the encrypted number and the policy identification number so that the operator can feedback the corresponding delivery strategy, the step further includes:

[0018] The encryption number is matched with existing policy identification numbers to determine the policy identification number corresponding to the encryption number, the number of the existing policy identification numbers is less than the number of the encryption numbers, and there is no one-to-one correspondence between the encryption number and the policy identification number.

[0022] The authorization hash information is asymmetrically encrypted to obtain encrypted authorization information.

[0023] In one embodiment, the step of initiating an encrypted query request to the operator based on the encrypted authorization information so that the operator feeds back an encrypted number matching the authorization information includes:

[0024] Based on the encrypted authorization information, an encrypted query request is initiated to the operator, so that the operator queries the corresponding number information in the database according to the encrypted Internet Protocol address information and timestamp information, shuffles the order of the successfully matched number information, generates an encrypted number, and feeds back the encrypted number.

[0025] In addition, to achieve the above-mentioned purpose, the present application also proposes an advertisement delivery device, which includes:

[0041] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0042] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0043] The main solution of the embodiment of the present application is: collect the user's authorization information, and based on the encrypted authorization information, initiate an encrypted query request to the operator to enable the operator to feedback an encrypted number that matches the authorization information; based on the encrypted number and the policy identification number, initiate an anonymous query request to the operator to enable the operator to feedback the corresponding delivery strategy; based on the delivery strategy fed back by the operator, deliver advertisements to the user.

[0044] At present, when companies with high-value data resources connect with advertising media to achieve precise advertising delivery, the data source often uses mobile phone numbers or device numbers as user primary keys, while data resource companies can only identify users' anonymous IDs as user primary keys, posing a risk of information leakage.

[0045] The present application provides a solution. After the query party initiates a query request, a match is first performed based on the encrypted authorization information, and then a query request is initiated with the encrypted number obtained by matching, and finally a delivery strategy is output. The only parameter that needs to be input during the entire process is the user's authorization information, and the corresponding delivery strategy is output. The data from each data source can be automatically associated, matched, and aligned, and efficient database indexing technology and anonymous query protocols can be used to accurately identify the target audience and improve the accuracy of advertising delivery, thereby reducing resource waste and increasing the conversion rate of advertising. At the same time, data from different data sources are used as basic data to protect the query privacy of the query party and the data privacy of the data provider. While protecting data privacy, the accuracy and efficiency of advertising delivery are improved, solving the technical problem of information leakage risk in traditional advertising delivery methods.

[0046] It should be noted that the executor of this embodiment is a company with high-value data resources, that is, a data asset company. The data asset company can implement advertising through a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device that can implement the corresponding functions, an advertising delivery device, etc., and this embodiment does not specifically limit this. The following takes the advertising delivery device as an example to illustrate this embodiment and the following embodiments.

[0047] The present application embodiment provides an advertisement delivery method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the advertising delivery method of the present application.

[0048] In this embodiment, the advertisement delivery method includes steps S10 to S30:

[0049] Step S10, collecting the user's authorization information, and based on the encrypted authorization information, initiating an encrypted query request to the operator, so that the operator feeds back an encrypted number matching the authorization information;

[0050] It should be noted that with the rapid development of Internet technology, the development space of the Internet advertising industry is getting bigger and bigger. Due to its advantages such as wide popularity, high cost performance and excellent media quality, it now accounts for more than 50% of the advertising market share. It can be seen that improving the accuracy of advertising and enhancing the level of risk control have become the basic demands of industry customers when placing Internet advertisements.

[0051] It can be understood that this embodiment involves the following participants: user mobile terminals, advertisers who pre-place advertisements, companies with high-value data resources (data asset companies), and operators with customer identity information. Advertisers entrust data asset companies to determine whether user mobile terminal A wants to place advertisements; user mobile terminal A authorizes data asset company B so that B has some user data, such as virtual ID, IPv6 (Internet Protocol Version 6) network information, timestamp, and placement strategy ID, etc. User mobile terminal A authorizes operator C so that operator C has user phone, IMEI (International Mobile Equipment Identity) and other identity ID information and IPv6 network information. The ultimate goal is that data asset company B initiates a request to operator C so that operator C can feedback whether to place advertisements without disclosing any of its own information and without seeing the other party's information. In this embodiment, the user mobile terminal can be a mobile phone or a tablet computer with a SIM (Subscriber Identity Module) card inserted, which is not specifically limited. This embodiment is explained by taking a mobile phone as an example.

[0052] In addition, it should be noted that the authorization information, i.e., the relevant information authorized by the user to the data asset company, at least includes Internet Protocol (IP) address information, timestamp information, and virtual identification number, wherein the Internet Protocol address information (IP address information) is the IPv6 address, the timestamp information is the timestamp corresponding to the IPv6 address, and the virtual identification number is the virtual ID, which is a set of unique user identification codes compiled by the data asset company based on the attributes of its own customers. Based on the IPv6 standard and a large amount of actual data testing and verification, it is known that if an IPv6 address is assigned to a mobile phone, the IPv6 address will no longer be assigned to other mobile phones, that is, the IPv6 address is a one-to-one relationship with the mobile phone, therefore, the IPv6 address can be used to query the relevant information of the mobile phone, such as: mobile phone number, IMEI number.

[0053] It is understandable that when users access advertising media platforms through mobile applications or web pages, if they confirm the authorization of the platform, the user's own relevant information will be uploaded to the media platform, and the user will receive a privacy policy notification to clarify how their data will be used. Media companies usually entrust data asset companies to locate user groups. Data asset companies use authorization information to query the operator for the corresponding number. The number can be a Phone number or an IMEI number. In this process, in order to ensure the security of data transmission and the privacy of data, the data asset company will encrypt the authorization information and use the encrypted authorization information to initiate a query request to the operator. The query request at this time can be considered encrypted, that is, an encrypted query request. The operator receives the encrypted authorization information and quickly matches the corresponding Phone / IMEI number in its own database based on the encrypted authorization information. The operator will also encrypt the matched Phone / IMEI number and generate an encrypted number to feed back to the data asset company.

[0054] In a feasible implementation, the steps in which a data asset company encrypts authorization information include: obtaining the user's authorization information, the authorization information including at least Internet Protocol address information, timestamp information, and a virtual identification number; hashing the authorization information to obtain authorization hash information; and asymmetrically encrypting the authorization hash information to obtain encrypted authorization information.

[0055] It should be noted that a secure hash algorithm can be used to process sensitive data in the authorization information. The secure hash algorithm can be a secure hash algorithm (SHA), such as SHA-256, which is not specifically limited. After the authorization information is processed by the secure hash algorithm, a corresponding hash value (a string of fixed length) can be obtained, which is the authorization hash information in this embodiment. Then the data asset company uses an asymmetric encryption algorithm to encrypt the transmitted data to ensure the security of the data during transmission. In this embodiment, the asymmetric encryption algorithm selected is the RSA (Rivest-Shamir-Adleman) algorithm.

[0056] In addition, it should be noted that not all authorization information needs to be encrypted for query. This embodiment performs hash processing and asymmetric encryption on the IP address information and timestamp information, and initiates an encrypted query request to the operator based on the encrypted IP address information and timestamp information, so that the operator can feedback a matching encrypted number.

[0057] In a feasible implementation, the step of initiating an encrypted query request to the operator based on the encrypted authorization information so that the operator can feed back an encrypted number that matches the authorization information includes: initiating an encrypted query request to the operator based on the encrypted authorization information so that the operator can search for corresponding number information in a database based on the encrypted Internet Protocol address information and timestamp information, shuffle the order of the successfully matched number information, generate an encrypted number, and feed back the encrypted number.

[0058] It should be noted that the database in this embodiment is the operator's own database. The operator will synchronize the hash processing of the IPv6 address and timestamp in its own database, and adopt the same secure hash algorithm as the data asset company, so that after decrypting the encrypted authorization information, it can match the corresponding Phone / IMEI number in its own database according to the authorization hash information.

[0059] It is understandable that the authorization information is usually in the form of a data group, that is, the IPv6 address and timestamp will be divided into multiple data groups, each of which contains multiple IPv6 addresses and timestamps corresponding to the IPv6 addresses. Therefore, the operator forms a corresponding number package according to the numbers matched to each data group. In order to ensure the security of data transmission, the order of the numbers in the number package can be disrupted and encrypted to obtain the encrypted number (package) of each data group. At this time, the order of the data in the data group is not one-to-one corresponding to the order of the corresponding encrypted number.

[0060] For example, assuming there are 10,000 IPv6 addresses and timestamps, the data is divided into 5 data groups, namely data groups a to e, each group contains 2,000 IPv6 addresses and timestamps, the 5 groups of data are encrypted at the same time, and a request is initiated to the operator. According to the uniqueness of IPv6, the Phone / IMEI number corresponding to each group of data is returned to the data asset company in the form of a number package. The number package corresponds to data groups a to e, which is 5 number packages. However, the numbers in the number package and the data order in the corresponding data group are not one-to-one corresponding, which further strengthens the security protection of the data.

[0061] In the specific implementation, the data asset company first collects the user's authorization information, including virtual ID, IPv6 address, timestamp, etc. These data are processed by a secure hash algorithm and then encrypted using an asymmetric encryption algorithm to ensure the security of data transmission. The data asset company initiates a query request to the operator, which contains the encrypted IPv6 address and timestamp information. After receiving the request, the operator will also synchronize and encrypt the data to ensure privacy protection during data processing. The operator uses its efficient database indexing technology to quickly match each group of IPv6 addresses with mobile phone numbers within X minutes before and after its timestamp in its own database (the value of X can be set according to actual conditions). After a successful match, the Phone / IMEI number package is encrypted and returned to the data asset company through a secure API (Application Programming Interface).

[0062] Step S20, based on the encrypted number and the policy identification number, initiating an anonymous query request to the operator, so that the operator can feedback the corresponding delivery strategy;

[0063] It should be noted that the delivery strategy refers to whether to deliver an advertisement. Generally speaking, when the delivery strategy is 1, it means delivery, and when the delivery strategy is 0, it means no delivery. The strategy identification number is the ID of the delivery strategy.

[0064] In addition, it should be noted that private information retrieval, also known as private information retrieval, is an information retrieval technology that protects user privacy. In private information retrieval, data asset companies can hide their query content through encryption or other means, so that operators cannot know the real query intention of the data asset company, so that information retrieval can be performed while protecting privacy.

[0065] It is understandable that the data asset company will initiate an anonymous query with the encrypted number + policy ID to the operator. The operator will query the corresponding delivery strategy of the number within the set time period in its own database and return several groups of data containing the delivery strategy to the data asset company.

[0066] Step S30: delivering advertisements to the user based on the delivery strategy fed back by the operator.

[0067] It should be noted that the data asset company determines whether to deliver advertisements to users corresponding to each number based on the delivery strategy corresponding to the number. If the delivery strategy corresponding to the number is 1, advertisements will be delivered to the mobile terminal belonging to the number. If the delivery strategy corresponding to the number is 0, advertisements will not be delivered to the mobile terminal belonging to the number, thereby achieving accurate delivery of advertisements.

[0068] This embodiment provides an advertising delivery method, which collects the user's authorization information, initiates an encrypted query request to the operator based on the encrypted authorization information, so that the operator can feedback the encrypted number that matches the authorization information; initiates an anonymous query request to the operator based on the encrypted number and the policy identification number, so that the operator can feedback the corresponding delivery strategy; and delivers advertisements to the user based on the delivery strategy fed back by the operator. After the query party initiates the query request, it first matches based on the encrypted authorization information, then initiates the query request with the matched encrypted number, and finally outputs the delivery strategy. The only parameter that needs to be input in the whole process is the user's authorization information, and the corresponding delivery strategy is output. The data of each data source can be automatically associated, matched, and aligned. At the same time, the data of different data sources are used as the basic data to protect the query privacy of the query party and the data privacy of the data provider. While protecting data privacy, the accuracy and efficiency of advertising delivery are improved.

[0069] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 , step S20 may include steps S201 to S203:

[0070] Step S201, based on the encrypted number and the policy identification number, initiate an anonymous query request to the operator, so that the operator can feedback the address query result and time query result corresponding to the encrypted number;

[0071] It should be noted that the data asset company initiates an anonymous query to the operator based on the encryption number and the policy identification number. The anonymous query adopts the Yao's protocol, a bilateral secure computing protocol. After using this protocol, the operator can perform the query operation without decrypting the data provided by the data asset company. Even if the data asset company and the operator do not trust each other, they can still perform data security applications and ensure data privacy.

[0072] It is understandable that the address query result refers to the IPv6 address that matches each number in the encrypted number, and the time query result refers to the timestamp that matches each number in the encrypted number. After the operator receives the anonymous query request from the data asset company, it will query the IPv6 address and timestamp corresponding to each mobile phone number within the set time period in its own database according to the number package. This process converts the encrypted Phone / IMEI number + policy ID into an IPv6 address + policy ID. The operator returns several groups of data containing IPv6 addresses and timestamps + policy IDs to the data asset company.

[0073] In a feasible implementation, before step S201, it includes: matching the encryption number with the existing policy identification number to determine the policy identification number corresponding to the encryption number, the number of the existing policy identification numbers is less than the number of the encryption numbers, and there is no one-to-one correspondence between the encryption number and the policy identification number.

[0074] It should be noted that the existing policy identification number is the existing policy ID. The data asset company can clearly know the meaning of each policy ID and the corresponding delivery strategy (whether to deliver). The operator is not clear about the meaning of the policy ID, but will get the corresponding relationship between the policy ID and whether to deliver. There is no substantial correspondence between the policy ID and the number in the encrypted number, and the number of existing policy IDs is much smaller than the number of numbers in the encrypted number. For example, 10,000 numbers correspond to 50 policy IDs. In this process, there will inevitably be a policy ID corresponding to multiple numbers. In other words, there is no one-to-one correspondence between the encrypted number and the policy identification number, which can avoid the situation where the mobile phone number is reversed through the policy ID when the number of policies is greater than or equal to the number of numbers.

[0075] Step S202, based on the address query result and the time query result, determining the matching address information that meets the delivery strategy corresponding to the strategy identification number;

[0076] In a feasible implementation, step S202 includes: determining the corresponding virtual identification number based on the address query result and the time query result; determining the matching virtual identification number in the virtual identification number that complies with the delivery strategy corresponding to the strategy identification number based on the correspondence between the virtual identification number and the strategy identification number; and determining the matching address information that complies with the delivery strategy corresponding to the strategy identification number based on the address query result corresponding to the matching virtual identification number.

[0077] It should be noted that the data asset company already has a corresponding relationship between each IPv6 address and policy ID, and finds the virtual ID corresponding to each set of address query results and time query results to achieve matching of the virtual ID and the policy ID. In other words, this process completes the matching of the delivery strategy.

[0078] It can be understood that the virtual ID is a set of unique user identification codes compiled by the data asset company based on the attributes of its own customers. Through the virtual ID, the data asset company can uniquely identify the behavior of the corresponding user on the media platform, and then determine which ones meet the needs through the correspondence between the virtual ID and the delivery strategy. The virtual ID that meets the needs is the matching virtual identification number, that is, the virtual ID that matches the delivery strategy corresponding to the strategy identification number, and the IPv6 address corresponding to the matching virtual identification number is the matching address information. For example, assuming that 10,000 IPv6 addresses are converted into corresponding virtual IDs, the data asset company can determine whether the corresponding user meets the strategy requirements based on the virtual ID. If it is determined that 3,000 meet the requirements, only these 3,000 users (IPv6 addresses) need to be mapped and delivered in the future to ensure the accuracy of the delivery.

[0079] Step S203: Based on the matching address information and the policy identification number corresponding to the matching address information, a stealth query request is initiated to the operator, so that the operator determines the matching number according to the matching address information and feeds back the delivery policy corresponding to the matching number.

[0080] It should be noted that the data asset company will send an anonymous query request to the operator with the policy ID corresponding to the matching address information. The operator will match the matching address information with the Phone / IMEI number again, and the successfully matched Phone / IMEI number is the matching number. Finally, the delivery strategy corresponding to the matching number is returned to the data asset company, so that the data asset company can determine the users who need to be advertised according to the delivery strategy and carry out precise advertising delivery.

[0081] Understandably, this process ensures that the advertising content is relevant and engaging to the audience, thereby improving the effectiveness of the advertisement and user satisfaction.

[0082] In the specific implementation, after receiving the Phone / IMEI number package, the data asset company matches these numbers with the existing policy ID. The data asset company will send an anonymous query to the operator with the matched number package and policy ID. The operator will query the corresponding delivery strategy for each mobile phone number within the set time period in its own database, and return several groups of data containing the delivery strategy to the data asset company. According to the delivery strategy returned by the operator, the data asset company will accurately deliver advertisements to a specific group of people.

[0083] This embodiment provides an advertisement delivery method, which initiates an anonymous query request to an operator based on an encrypted number and a policy identification number, so that the operator can feedback the address query result and time query result corresponding to the encrypted number; determines the matching address information that meets the delivery strategy corresponding to the policy identification number based on the address query result and the time query result; initiates an anonymous query request to an operator based on the matching address information and the policy identification number corresponding to the matching address information, so that the operator can determine the matching number according to the matching address information, and feedback the delivery strategy corresponding to the matching number. After the query party initiates the query request, it first matches based on the encrypted authorization information, then initiates the query request with the encrypted number obtained by matching, and finally outputs the delivery strategy. The parameters that need to be input in the whole process are only the user's authorization information, and the corresponding delivery strategy is output. The data of each data source can be automatically associated, matched, and aligned, and the efficient database indexing technology and anonymous query protocol are used to accurately identify the target audience, improve the accuracy of advertisement delivery, thereby reducing resource waste and improving the conversion rate of advertisements. At the same time, the data of different data sources are used as basic data to protect the query privacy of the query party and the data privacy of the data provider, and improve the accuracy and efficiency of advertisement delivery while protecting data privacy.

[0084] For example, to help understand the implementation process of the advertising delivery method obtained by combining this embodiment with the above-mentioned embodiment 2, please refer to Figure 3 , Figure 3 A brief flowchart of an advertisement delivery method is provided, specifically:

[0085] In the overall business interaction, there are two usage scenarios. The first is that the data asset company queries the operator for the Phone / IMEI number package corresponding to IPv6 through the IPv6 address and timestamp. The second is that the data asset company queries the operator for the delivery strategy through the Phone / IMEI number package, and finally delivers advertisements to specific groups of people accurately.

[0086] The first usage scenario: query the corresponding Phone / IMEI number package through IPv6 address and timestamp.

[0087] Data preparation and encryption: Data asset companies first collect users' authorized data, including virtual IDs, IPv6 addresses, timestamps, etc. These data are processed by a secure hash algorithm (such as SHA-256) and then encrypted using asymmetric encryption technology (such as RSA) to ensure the security of data transmission.

[0088] Initiate a query request: The data asset company initiates a query request to the operator. The request contains the encrypted IPv6 address and timestamp information. After receiving the request, operator C will also synchronously encrypt the data to ensure privacy protection during data processing.

[0089] Database matching and return results: The operator uses its efficient database indexing technology to quickly match each group of IPv6 mobile phone numbers within a certain period of time before and after its timestamp in the database. After a successful match, the Phone / IMEI number package is encrypted and returned to the data asset company through a secure API interface.

[0090] The second usage scenario: query the delivery strategy through the Phone / IMEI number package.

[0091] Policy ID matches mobile phone number to prevent reverse inference: After receiving the Phone / IMEI number package, the data asset company matches these numbers with the existing policy ID. There is no substantial correspondence between the policy ID and the number in the number package, and the number of policy IDs is much smaller than the number of numbers, to avoid reverse inference of mobile phone numbers through policy IDs when the number of policies is ≥ the number of numbers.

[0092] Initiate an anonymous query request: The data asset company will send the matched number package and policy ID to the operator to initiate an anonymous query. Using Yao's protocol, the operator can perform the query without decrypting the data, thus maintaining the privacy of the data.

[0093] Query the delivery strategy and return the result: The operator queries the database for the delivery strategy corresponding to each mobile phone number within the set time period, and returns several groups of data containing the delivery strategy to the data asset company.

[0094] Precision delivery execution: Based on the delivery strategy returned by the operator to the data asset company, the data asset company delivers precise advertising to a specific group of people, ensuring that the advertising content is relevant and attractive to the audience, thereby improving the effectiveness of advertising and user satisfaction.

[0095] In both scenarios, data privacy and security are fully considered and guaranteed. Through the application of encryption technology and anonymous query protocols, participants can effectively cooperate to achieve accurate advertising without leaking sensitive information.

[0096] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the advertising delivery method of the present application.
