Patent Application
20230023325
This disclosure is directed to computers, and computer applications, and more particularly to computer-implemented methods and systems for recommending and/or approving a header for an electronically communicated message.
In current messaging systems, a sender who would like to send a message in commercial communications, such as promotional messages, needs to register a header which would identify the sender. The header is shown as the “message from” information for the promotional messages. The header signifies who is the sender and thus plays an important role to grab the attention of the customer/recipient. The header provides immediate information to identify the sender but may also provide information identifying the content of the message.
In the current header registration process, headers are provided by the registering entity or can be requested by the sender. This results in a high probability of the header being similar to an existing header. Moreover, with the header being chosen by the sender, the headers can be easily obtained by actors that can pose as another. In addition, the message header chosen may include special characters that can cause a threat to the system by means of phishing.
In some embodiment, a computer implemented method for recommending a header for a message is disclosed. In one embodiment, the method includes the steps of receiving a request from an entity for a header for a message, generating at least one proposed header in response to the request based on at least one of a name of the entity, a brand of the entity, a category of a product identified in the message and content of the message, classifying the at least one proposed header using a machine learning model trained based on historical complaints on previously used headers related to the at least one of a name of the entity, a brand of the entity, a category of a product identified in the message and content of the message used to generate the at least one proposed header and recommending at least one of the at least one proposed header to the requesting entity based on the classification. In one embodiment, the at least one proposed header is generated using a machine learning model trained based on the at least one of a name of the entity, a brand of the entity, a category of a product identified in the message and content of the message.
In one embodiment, in a case where the request for a header includes a specific header requested by the entity, the method includes classifying the specific header using a machine learning model trained based on historical complaints related to the at least one of a name of the entity, a brand of the entity, a category of a product identified in the message and content of the message, approving or disapproving the specific header based on the classification. In one embodiment, in a case where the specific header is approved, receiving a selection of one of the recommended header and the approved specific header from the entity and registering to the entity the selected header for the message.
In one embodiment, the method includes training the machine learning model by parsing the previously registered headers of the historical complaints into a plurality of datasets, computing a Levenshtein distance comprising a number of edits required to get the same header using the datasets, forming a trigram from the previously registered headers, computing a Jaccard distance and learning a decision tree classifier using the plurality of historical complaints datasets, the Levenshtein distance and the Jaccard distance, that can learn rules based on the Levenshtein and Jaccard distances that may lead to wrongful association activities. In one embodiment, the method includes retrieving a list of registered headers similar to the at least one proposed header, computing the Levenshtein and Jaccard distances between each pair of the at least one proposed header and the similar registered header and using the rules from the decision tree classifier to flag whether or not the specific header should be approved.
In one embodiment, the method may include training the machine learning model to learn a threshold wherein headers having a classification greater than the threshold are not recommended as having a high probability of being wrongly associated with the requesting entity and headers having a classification lower than the threshold are recommended as having a high probability of not being wrongly associated with the requesting entity.
In one embodiment, the method may include approving the at least one recommended header based on a dissimilarity variance with distributed registered headers. In one embodiment, the method may include approving the at least one recommended header using a distributed computation protocol while preserving privacy of the entity across a network of message operators.
A computer system that includes one or more processors operable to perform one or more methods described herein also may be provided.
A computer readable storage medium storing a program of instructions executable by a machine to perform one or more methods described herein also may be provided.
Further features as well as the structure and operation of various embodiments are described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.
In one embodiment, there is disclosed a system and method that recommends or approves a header for a message based on past complaints on headers of a similar nature that were previously registered, as well as information related to the sender such as one or more of the categories of product dealt in by the sender, the name of the sender, a brand of the sender and content of the intended message. In one embodiment, the recommendation is provided by an artificial intelligence (AI) model using machine learning. In one embodiment, the system and method approve a header submitted by the sender based on the AI model trained using the historical complaints data of wrong association and the list of registered headers. In one embodiment, a dictionary-based AI model recommends headers based on the category and subcategory of the products dealt in by the sender. In one embodiment, different header options can be provided by the system based on the brand, a sub-brand, or it can be derived based on the content of the message which the sender would like to send. The method and system to recommend headers that avoid misusage of brand names and popularity of the sender such that the probability of activities from wrong association can be minimized. In one embodiment, the system and method approve the recommended header based on dissimilarity variance with distributed registered headers across the network of operators. In one embodiment, the method and system approve a new header using a distributed computation protocol while preserving privacy of the sender across the network of operators. In one embodiment, the method and system provide recommended headers with efficient and differential scrubbing capability based on the association between the recommended header with the category and message template.
The method and system are an improvement over prior art header registration systems by providing optimal granularity for generating headers for recommendation thereby avoiding misusage of brand names and minimizing the probability of activities from wrong association.
In step S14, the at least one proposed header is classified using a machine learning model trained based on historical complaints on previously used headers. In one embodiment, in step S14, the classification is based on historical complaints on previously used headers related to the at least one of a name of the entity, the brand of the entity, the category of a product identified in the message and content of the message used to generate the at least one proposed header. In step S16, at least one of the at least one proposed header is recommended to the requesting entity based on the classification. In one embodiment, step S16 includes training the machine learning model to learn a threshold wherein headers having a classification greater than the threshold are not recommended as having a high probability of being wrongly associated with the requesting entity and headers having a classification lower than the threshold are recommended as having a high probability of not being wrongly associated with the requesting entity.
The operator A of network 16 submits the request for a header to the header recommendation system 18. The header recommendation system 18 includes several data repositories, including Entity Name 20, Message Content 22, Product Category 24, and Brand 26. The data repositories also include Complaint Registry 28. The header recommendation system 18 also includes AI model 30.
The header recommendation system 18 receives the request 14 from the entity 12 for a header for a message. The header recommendation system 18 generates at least one proposed header in response to the request based on information from one or more of the name of the entity from repository 20, a brand of the entity from repository 26, a category of a product identified in the message from repository 24 and content of the message from repository 22. In one embodiment, the at least one proposed header is generated using the machine learning AI model 30 trained based on the at least one of the name of the entity, the brand of the entity, the category of the product identified in the message and content of the message.
The header recommendation system 18 classifies the at least one proposed header using the AI model 30. In some embodiments, the AI model 30 is a machine learning model trained based on historical complaints in complaint registry 28. The classification is based on complaints on previously used headers related to the at least one of the name of the entity, the brand of the entity, the category of a product identified in the message and content of the message used to generate the at least one proposed header.
The header recommendation system 18 recommends at least one of the at least one proposed header to the requesting entity 12 based on the classification. For example, recommendation 32 of header ABC is sent to the entity 12. In one embodiment, the AI machine learning model 30 is trained to learn a threshold wherein headers having a classification greater than the threshold are not recommended as having a high probability of being wrongly associated with the requesting entity and headers having a classification lower than the threshold are recommended as having a high probability of not being wrongly associated with the requesting entity.
Upon acceptance of the recommended header 32 by the requesting entity 12, The operator A of network 16 registers the header in header registry 34 and transmits at 36 the message content 38 with the ABC header 40. Header 40 may also include characters identifying the network operator, in this case shown as OA.
Also shown in
Upon acceptance of the recommended header 48 by the requesting entity 42, The operator B of network 46 registers the header XYZ in header registry 50 and transmits at 52 the message content 54 with the header OB-XYZ 56. As a result of the header recommendation system 18, both messages 38 and 54 give a clear differentiation to the network subscriber 58 on the sender based on the different headers 40 and 56.
In one embodiment headers being registered by the operator may include characters to identify certain meta-data which at a later point in time during scrubbing would be useful to enhance the scrubbing process. In addition, in one embodiment, the added characters to identify certain meta-data could also be useful in handling of the complaints with faster resolutions. In one embodiment, the added characters can reduce the number of validation steps for a recommended header as the category, and relation with a template would be correctly mapped.
In one embodiment, the header may include a prefix which identifies if the header finally registered is recommended by the system or selected by the requesting entity. This information can help at later stages of complaint handling and in analytics to determine which kind of header have a high percentage of being wrongly associated and may be the result of a fraud. In one embodiment, the prefix can be used by the header recommendation system 18 to determine which headers have a higher complaint rate in comparison and flagging those headers that have a rate above a threshold for disapproval as being possibly wrongly associated.
In one embodiment, the first character of the header can be set as an R for recommended or S for selected. For example, the header OA-RG-ABCBNK specifies a system recommended header for the entity ABC, whereas OA-SL-XYZBNK specifies a header which has been chosen by entity XYZ.
In one embodiment, the header may include characters which identifies if the sender is a local entity or a global entity. For example, the first character could be G for global or L for local, thus OA-RG-ABCBNK specifies a global entity ABC, whereas OA-SL-XYZBNK specifies a local entity XYZ.
As shown in
Step S32 includes forming a Trigram from the previously registered headers. Trigrams are a special case of the n-gram, where n is 3, the n-gram being a contiguous sequence of n items from the text of the header. The trigram is used for performing statistical analysis of the text of the header. The items can be phonemes, syllables, letters, words or base pairs of the header.
Step S34 includes computing a Jaccard distance. Jaccard distance measures the dissimilarity between the data sets obtained from the parsed headers. The Jaccard distance is obtained by subtracting the Jaccard similarity coefficient from 1.
Step S36 includes learning a decision tree classifier using historical complaints data, the Levenshtein distance and the Jaccard distance that can learn the rules based on the Levenshtein and Jaccard distances that lead to wrongful activities.
The execution of the model for the submitted header includes step S38 of retrieving a list of registered headers similar to the submitted header, step S40 of computing the Levenshtein and Jaccard distances between each pair of the submitted header and the similar registered headers and step S42 of using the rules from the decision tree classifier to flag if the submitted header should be approved or not.
In step S46, regular scrubbing is done against these hashes to deliver an SMS header. In step S48, a new header is received from an entity by the network operator, such as a telephone service provider (TSP). In step S50 the TSP initiates set up of a multi-party computation (MPC) protocol between different TSPs. In step S52 the TSP shows that the data used by each party in the MPC is consistent with the hash of the header registered in Step S46. In step S54, a selected similarity metric is computed. The similarity may be any one of a Jaccard distance, a Hamming distance, a Levenshtein or other similar distance metric. In one embodiment, the Hamming distance measures binary data strings of the headers and the distance between two strings of equal length is the number of bit positions at which the bits are different. In step S56 if the metric is similar within a threshold distance to any of the registered headers by any of the TSPs, in S58 the output will be 1 (disapproved) else in step S60 the output will be 0 (approved).
In one embodiment, the MPC Task Specification may take the form:
In one embodiment, a new header approval based on MPC execution may take the form: registered header public data grounded by each TSP is:
