## Background
FIELD
The present disclosure relates to the field of systems that are used to provide anonymous data in response to request for information.
BACKGROUND
Individuals are concerned about privacy today and do not desire their personal information or identifying information to be shared without their permission. Businesses and other entities, however, often desire feedback from institutions on the results associated with actions taken by the business or entity. For example, a business is often interested in the characteristics of individuals responding to an advertisement.
Institutions would like to provide this information to the business but also retain the privacy of their customers or clients. Previously, institutions may have been able to provide semi-anonymous data by building multiple models at different scales but this approach is labor and data intensive, requires frequent updating and management, and can be overcome by an iterative approach that identifies personally-identifiable information.
Thus, there is a need for a system to provide anonymous data in response to a request for information.
SUMMARY
The following presents a simplified summary of one or more embodiments of the present invention, in order to provide a basic understanding of such embodiments.

DETAILED DESCRIPTION
Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident; however, that such embodiment(s) may be practiced without these specific details. Like numbers refer to like elements throughout.
Given the desire for privacy in today's society, individuals are hesitant to allow their personal information to be shared with other people or businesses. Nevertheless, businesses, health care providers, and educational system, among other entities, are often interested in characteristics of individuals meeting certain criteria. For example, a business may be interested in the characteristics of individuals responding to an advertisement in order to better understand or target advertisements for the future. Similarly, health care providers may be interested in who is responding to medication or treatment and the characteristics of those individuals. Providing anonymous data that mirror the reality of individual data but that is not a true representation of reality can improve targeted, predictive modeling while still retaining individual privacy. A system for providing anonymous data in response to a request for such information is therefore advantageous in a variety of fields including marketing, education, and health.
In an embodiment, the system transforms individual data, such as customer data present in financial institution records, by adding to the data and/or modifying the data. In this manner, the transformed data is presented to the user and/or downstream applications and is both responsive to the request for information and anonymous so that the data are compliant with laws, rules, and regulations. The transformation creates formatted data that is extracted from personally-identifiable data. In some embodiments, a key is inserted into the transformed data to confirm that the transformed data are anonymous. In an embodiment, the presence of this key in the transformed data improves or permits the system to send the anonymous data to the user.
In FIG. 1, a method 100 for providing anonymous data in response to a request for information, wherein the request has the potential to disclose personally-identifiable information, is provided in some aspects. In an embodiment, the method includes receiving a request for information relating to a population of interest from a user; determining criteria associated with the population of interest, wherein the criteria define an individual representative of the population of interest; determining a characteristic of the individual within one or more categories; classifying the characteristic of the individual into a cluster, the cluster comprising a subset of all possible outcomes for the category; classifying a plurality of individuals from a database into clusters based on the one or more categories; determining a subset of the plurality of individuals that are similar to the individual representative of the population of interest based on the clusters; transforming the characteristics of the individuals in the subset to generate anonymous data responsive to the request for information; and providing the anonymous data to the user.
In block 110, in some embodiments, the system receives a request for information relating to a population of interest from a user. For example, a user may be interested in the efficacy of an advertisement and request information from a financial institution regarding the financial institution customers that made a purchase when the advertisement was running. In another example, a user may be interested in receiving information regarding medical outcomes of a group of patients receiving a treatment. In a still further example, a user may be interested in receiving information regarding school choices of students and test scores. In each of these examples, laws, regulations, or policies limit disclosure of information that may identify individuals in the population of interest (i.e., financial institution customers, patients, students). Thus, a method of providing anonymous data associated with these populations of interest would comply with rules and regulations but assist users that are interested in information associated with the population of interest.
In an embodiment, a population of interest is a group of individuals that share one or more characteristics. In some embodiments, the population of interest is defined by an action taken by the individuals in the population. For example, each individual in the population may have made a purchase at a specific time, made a decision regarding matriculating at a school, or participated in a medical study. In some embodiments, the action is relevant to the user searching for information. For example, a merchant may desire to know the characteristics of individuals that made a purchase at a store during a specific period of time in order to gauge the success of a marketing campaign. Similarly, a doctor may desire to know the characteristics of a population of individuals in a medical study who were administered a specific medication. In some embodiments, the population of interest is a group of individuals that are also customers of a financial institution.
In an embodiment, the request is received from a user. The user may be a private individual or corporation, a nonprofit organization, or a governmental agency. In some embodiments, the user is also a customer of the financial institution. For example, a business customer of the financial institution may desire to know which individual customers of the financial institution made a purchase in response to an advertisement campaign.
In an embodiment, the system receives the request electronically. For example, the user may submit the request via an online graphical user interface. The online graphical user interface may allow the user to specify various demographic and/or financial information-related characteristics of the population of interest. For example, the system may provide a list of types of data that the system can use to distinguish populations. Purchases, deposits, and transfers may all include information that can be used to define a population. In one example, deposits from employers or payor names on checks may be used to generate a population of individuals that work at or receive funds from a specific entity.
In some embodiments, the request comprises criteria for individuals in the population of interest. The criteria may be used to define the population. The criteria may be obligatory or aspirational when defining the population. In other words, in some embodiments, an individual must meet the criteria in order to be considered part of the population. In another embodiment, an individual should meet or come close to meeting the criteria to be considered part of the population. The criteria may be numerical (e.g., a minimum account balance or transaction amount), binary (e.g., the user is a home owner or the user is not a home owner), categorical (e.g., city of residence), ordinal (e.g., stages of cancer), geographic (e.g., location, proximity), temporal (e.g., time, elapsed time, date), or the like.
Providing information in response to the request for information would traditionally provide data that could be reverse-engineered and allow the identity of one or more individuals in the population to be determined. For example, an iterative approach could be used to identify a single individual in the population and associate that individual with personal information (e.g., financial account data, medical records, educational records, political records). In contrast, the disclosure herein discloses a system and method that provides information in response to the request for information, wherein the information is anonymous but still responds to the request for information.
In block 120, in some embodiments the system determines criteria associated with the population of interest. In a first embodiment, the system determines the criteria by receiving them from the user. In a second embodiment, the system determines the criteria by evaluating the request and generating criteria that when met would fulfill the request. For example, a merchant may request information on all individuals that purchased during a sale period. The system determines the criteria as being anyway that had a purchase transaction at the merchant during a specific time period. In some embodiments, the criteria are determined based on a combination of being received from the user and being determined in order to meet the request.
In some embodiments, the system identifies an individual representative of the population of interest in order to determine the criteria. In some embodiments, the individual meets all of the criteria requested by the user when submitting the request for information. For example, the user may have requested information on how many people purchased an item on a specific date between a certain time and for a certain amount (e.g., a range for the transaction amount). The individual representative of the population of interest will be selected by the system based on the individual meeting all of these criteria. In some embodiments, the system evaluates a database of individuals, such as a financial institution database comprising transaction history data, to identify the individual.
In an embodiment, no individual in the database meets 100% of the criteria selected by the user. In this situation, the system selects an individual that most closely meets the criteria selected by the user. For example, the system may select an individual that meets the location and time requirement but is outside the range for transaction amount. The system will, in this example, select an individual that is closest to the transaction amount range. In some embodiments, the user provides a hierarchy of importance to the different criteria used to define the population of interest. For example, in the context of educational decisions, the user may indicate that the hierarchy of criteria from most important to least important are test score, grade point average, legacy, in-person visit. In this way, if no individual in the database perfectly meets the criteria then the system will first attempt to identify an individual that meets all of the criteria except for the least important criteria (e.g., in-person visit).
In some embodiments, the system accesses public information regarding users to identify the individual or supplement information from the database. For example, the system may access social media sites to determine whether an individual is a fan of or likes a specific merchant.
In block 130, in some embodiments the system determines a characteristic of the individual within one or more categories. As used herein, a characteristic is facet associated with the behavior, account history, or demographics of the individual. For example, the characteristic may be the frequency with which the individual makes a purchase at a merchant, the average time between purchases, the percentage of time the individual votes early in elections, or the number of times a week the individual exercises. As will be discussed, the categories determined by the system will vary based on the request for information and, in some embodiments, be directly relevant to the request for information. For example, the number of times a week that the individual exercises may not be relevant to a request for information regarding individuals that made a purchase during a sale.
Examples of account history characteristics include balances, purchase or return history, contributions to accounts (e.g., retirement savings, auto-deposit of paychecks), specific types of transactions (e.g., student loans, mortgage payment), and the like.
Examples of demographic characteristics include location, age, income, home ownership status, family status (e.g., married, divorced, children), educational level, employment status, and the like.
In an embodiment, the system determines the characteristic of the individual by accessing records associated with the individual. For example, a financial institution may have records associated with the financial transaction history and the demographics of the individual. Behavioral characteristics may be determined from the transaction history. As discussed, in some embodiments the characteristics are selected based on their relevance to the request. In some embodiments, however, the system determines characteristics that are not directly relevant to the request. For example, the system may conduct a multivariate analysis (e.g., principle components analysis) to determine which of the characteristics are associated with the request for information (e.g., response to medical treatment or the like). In this example, characteristics that may not appear to be directly relevant are identified by the system as associated with the response variable and determined by the system. Without wishing to be bound by theory, in some embodiments these characteristics may co-vary with variables that are relevant but not measured.
In block 140, in some embodiments the system classifies the characteristic of the individual into a cluster, wherein the cluster comprises a subset of all possible outcomes for the category. As used herein, a cluster is a grouping of ranges or values for the characteristic. For example, if an individual is 37 years old, the cluster may classify the individual into a cluster of from 30-40 years old. In some embodiments, the cluster is a value or set of values from a categorical or binary grouping. For example, place of residence may include U.S. state as a characteristic. States in the southeastern United States (e.g., North Carolina, South Carolina, and Georgia) may be grouped together into a cluster.
In an embodiment, the cluster includes a subset of all possible outcomes for the category. For example, all possible outcomes for age include the range of all ages in the population of interest. For example, a medical database may include the age of all individuals in the medical study from age 23 to age 47. Here, the range in ages for the population is 23-47.
The clusters may be defined in a variety of ways and often the method for defining the clusters in the category will depend on the type of category. For example, clusters within age may be defined based on generation (i.e., divide individuals in the category based on which generation they fall into), legally-relevant divisions (e.g., under 18, between 18-65, over 65), natural breaks (e.g., every 5 or 10 years), or the like. In some embodiments, categorical characteristics are grouped based on underlying characteristics of the categories (e.g., state of residence may be grouped based on proximity to one another).
In block 150, in some embodiments the system classifies a plurality of individuals from a database into clusters based on the one or more categories. In an embodiment, the individual identified as representative of the population of interest (e.g., an individual that meets all or most of the criteria) is used to identify other individuals in the database that are similar. These other individuals, in one embodiment, make up a plurality of individuals that can be evaluated in order to provide anonymous data in response to the request for information.
In some embodiments, the characteristics of the plurality of individuals are identified and classified into clusters in the same manner as the representative individual. In one embodiment, all individuals in a database, such as a financial institution database, are identified and classified based on the characteristics. In some embodiments, the individuals in the database are pre-classified into a variety of categories and the system evaluates only those characteristics that are of relevance to the current inquiry. The resulting data include: (1) a single individual representative of the population of interest and categorized into clusters based on the request for information and (2) a plurality of individuals from the database classified into clusters based on the categories used to cluster the single individual. It should be understood that the criteria used to identify the representative individual may differ from the characteristics used to cluster the representative individuals and plurality of individuals from the database.
In block 160, in some embodiments the system orders the clusters based on a magnitude of the clusters and a distribution of the clusters in the population. In an embodiment, the system order the groups of clusters based on the magnitude of the clusters. For example, the individual representative of the population of interest is 42 years old and clustered into the age group of 40-50 years old. The remaining individuals in the population are classified into age groups from 20 (the youngest individual in the population) to 70 (the oldest individual in the population). The system has determined that clusters defined by decades of age generate an appropriate distribution in the population. By clustering the plurality of individuals into decades of age, the resulting population includes 5 individuals from age 20-30, 32 individuals from age 30-40, 27 individuals from age 40-50, 13 individuals from age 50-60, and 2 individuals from age 60-70. The system then orders these clusters by magnitude. For example, the clusters may be ordered by number of individuals in each cluster. In this manner, the clusters are ordered so that the first cluster includes the 2 individuals from age 60-70, the second cluster includes the 5 individuals from age 20-30, the third cluster includes the 13 individuals from age 50-60, the fourth cluster includes the 27 individuals from age 40-50, and the fifth cluster includes the 32 individuals from 30-40.
In this manner, the clusters have been ordered based on magnitude and a distribution. In this case, the distribution is from smallest magnitude to largest magnitude and generates a harp-shaped distribution. Turning briefly to FIG. 3A, the clusters ordered in the distribution are provided. As seen in FIG. 3A, the clusters are ordered by magnitude based on number of individuals within each cluster. The smallest cluster is the 60-70 year old group, with only two individuals, and the largest cluster is the 30-40 year old group, with 32 individuals. The representative individual falls within this group.
The magnitude of the clusters may be determined in a variety of ways. For example, the sum of the characteristics within the cluster may be used to determine the magnitude. In the above example, the ages of each individual within the cluster can be added together to get the magnitude of the cluster. For ease of calculation, assume that the age of each individual in the cluster is at the midpoint (e.g., 25, 35, 45, 55, and 65). The clusters include 5*25 (age 20-30), 32*35 (age 30-40), 27*45 (age 40-50), 13*55 (age 50-60), and 2*65 (age 60-70). These clusters, when ordered by magnitude determined by the product of the number of individuals in the cluster and their value, are cluster 1: age 20-30 (5*25=125 magnitude), cluster 2: age 60-70 (2*65=130 magnitude), cluster 3: age 50-60 (13*55=715 magnitude), cluster 4: age 30-40 (322*35=1120 magnitude), and cluster 5: age 40-50 (27*45=1215 magnitude). In this example, the order of the clusters based on magnitude from smallest to largest has changed. See FIG. 3B for an example of how the changing method of determining magnitude affects the ordering of clusters. As shown in FIG. 3B, the lowest clusters and highest clusters have changed from 60-70 to 20-30 at the lowest end, and from 30-40 to 40-50 at the highest end. The ordering of the clusters affects the function that will be determined based on them when a zeta function is used for fractal mirroring of the individuals.
As should be understood, there are a variety of ways that magnitude of clusters can be determined. For example, the magnitude can be determined based on pendency (e.g., length of account age), frequency (e.g., number of transactions), or most recent (e.g., time elapsed since last log-in).
The above-example provided an illustration using a distribution from smallest to largest of the clusters based on magnitude, however defined. In some embodiments, however, the distribution is a different type of distribution. For example, the distribution may be a normal distribution, an exponential distribution, a Poisson distribution, or the like. In an embodiment, the shape of the distribution is selected based on the request for information. For example, a normal distribution may be appropriate when a request for information is searching for a characteristic individual. The user is not seeking information on outliers at either end of a distribution but rather the most likely individual in the center of the normal distribution. In another embodiment, the user may be requesting information regarding anomalies or outliers and therefore select an exponential distribution.
In an embodiment, ordering the clusters based on magnitude and distribution is a step in a fractal analysis of the data. A fractal analysis order fractals strings or clusters into a self-similar set (i.e., clustering into groups based on similar characteristics) and then uses a Zeta function to determine an equation that represents the group or a plurality of groups. The benefit of a fractal analysis is that fractal representations are scale-independent. In other words, whether the user is looking at a small scale analysis or a large scale analysis, the representation of the population of interest will accurately portray the population all along the scales. This is in contrast to some methods of providing information on large populations, which use averages, because an average of a large population loses detailed information at finer resolution. The fractal mirroring method disclosed herein is capable of generating formula that defines various portions of the population of interest, such as a small population that closely mirrors the representative individual or a larger population that has greater differences between the population and the representative individual. In some embodiments, the formula describing the smaller populations can be aggregated to generate a formula describing the larger population.
In block 170, in some embodiments the system determines a function that represents the individual based on the ordered clusters and the distribution. In an embodiment, the function represents the individual in an anonymous manner. In other words, the function defines the characteristics of the individual but cannot be used to determine specific personal information about an individual.
In one embodiment, Zeta functions are used to determine a function from the ordered clusters. Zeta functions are known to one of skill in the art and permit a function to be determined based on an ordered set of groups based on a fractal analysis. In an embodiment, the Zeta function is the Riemann zeta function. In some embodiments, a variety of other zeta functions can be used, such as the Barnes zeta function, Hasse-Weil zeta function, Hurwitz zeta function, Matsumoto zeta function, or Shimizo zeta function. In some embodiments, the zeta function to be used is dependent upon the request for information, the distribution, and/or the nature of the data.
In some embodiments, the function is determined based on an average of the characteristics in the group. For example, a mean, a median, a mode, a standard deviation, and/or a range may be used to characterize individuals clustered within a group. For example, if it has been determined that a group of individuals is similar to the representational individual based on clustering analysis, then the average age of that group may be used as a representational age for the anonymous individual.
In an embodiment, multiple characteristics are used to identify individuals from among the plurality of individuals that are similar to the representative individual. In this way, age may be used to find a subset of individuals that are similar to the representative individual, and then state may be further used to identify individuals that are of a similar age and state to the representative individual. This may result in a smaller subset of individuals that are similar to the representative individual. It should be understood that the number of characteristics affects the number of individuals in the group that is characterized to respond to the request for information. Too many characteristics will result in a small group that will be difficult to obscure and therefore in some embodiments the system has a maximum number of characteristics or a minimum number of individuals in the identified group.
In an embodiment, the system deletes or erases the underlying data after the function representative of the population or individual of interest is generated.
In block 180, in some embodiments the system provides the function to the user, wherein the function responds to the request for information without providing identifying information for the individual. In some embodiments, the system provides the function electronically such as via an electronic transfer. In an exemplary embodiment, the system provides a numerical or representational value that responds to the request, e.g., a representational depiction of an anonymous individual responding to the advertisement. The representational depiction may include characteristics that are directly relevant to the request for information, such as amount spent, time of transaction, and the like, but may also include characteristics that are not directly related to the request for information, such as homeowner status and relationship status.
In an embodiment, the response provides anonymous information that is derived from the individuals identified by clustering of self-similar individuals in a group. As discussed, in one embodiment a Zeta function is used to characterize these individuals. In some embodiments, an average is used to characterize these individuals.
It should be understood that the steps disclosed herein are not limiting. Additional steps in the method of providing anonymous data in response to a request for information may be performed. Similarly, the order of the steps disclosed herein is not required. In some embodiments, the order may change based on the needs of the user.
Turning now to FIG. 2, a block diagram illustrates an environment 200 for providing anonymous data in response to a request for information. The environment 200 includes a user device 206, an institution system 208, and in some embodiments a third party system or device 210. The user 202 is associated with the user device 206 and can include an owner of the device 144, parties that have authorized access to the device 206, an employee, associate, and the like. The user device 206 can include any type of device such as a computing device, a mobile device, and so forth. The environment 200 further includes one or more other third party systems 292 (e.g., a partner, agent, or contractor associated with the institution system 208), and one or more external devices 296 (e.g., USB flash drives, hard drives, and other removable media).
