Not applicable.
Retailers and other marketers today spend large sums of money building marketing databases. These databases may contain records pertaining to millions of individual consumers, which may be actual customers of the retailer or prospective customers (“prospects”). For each consumer, the database may contain hundreds or even thousands of individual data points. The data may include demographic information, lifestyle information, purchasing habits, and other information pertinent to marketing efforts or marketing analytics. That data may be used to personalize offers, cross-sell products, or even introduce completely new products. In addition, the data is used to understand the effectiveness of the retailers' marketing activities so that they may refine their marketing processes, in order to increase their return on investment. While beneficial to the retailer, this refinement also benefits consumers by bringing those consumers more relevant offers and products, rather than blanketing the consumers with offers or marketing messages that are not relevant to them. Recent investigations reveal that while a small number of consumers wish to “opt out” of targeted marketing efforts and thus prefer to receive untargeted advertising, far more consumers prefer that—if they are to receive marketing messages—that those messages be tailored to accurately reflect those products and services in which they are in fact likely to be interested.
Historically, the effective use of consumer data for making offers and analyzing marketing campaign effectiveness has only been possible in marketing channels where consumer personalized information, such as name, address, telephone number, or email, was readily available. These channels include traditional “offline” channels, such as, for example, direct mail efforts, in which a mailing list of consumers and addresses is used to physically mail marketing offers to individual consumers. Online advertising efforts, such as banner advertising on web pages and various marketing messages that appear when using mobile devices such as smartphones and tables, have historically been largely untargeted efforts because of the lack of identifying information in these channels that makes targeted advertising possible. For example, a consumer browsing to a particular webpage during an online search typically does so without providing any personally identifying information, and consumers are reluctant to reveal such information to all but the most trusted websites and other online providers. Nevertheless, tying these online advertising channels to offline channels would be highly advantageous to retailers and other marketers, since this would allow the marketer to coordinate its marketing efforts across platforms. A marketer could thereby use a more unified, consistent approach in the modern world of multi-channel marketing. The marketer could also much more effectively analyze the results of its multichannel advertising efforts. For example, if such coordination were accomplished, the retailer might be able to better understand the degree to which its online marketing drives offline sales of its products. Thus a marketer who places an online banner advertisement might be able to know how many views of the online banner advertisement actually led to in-store sales at its physical retail locations. This would allow the marketer to more effectively gauge the effectiveness of its various online marketing options, and would thereby result in an advertising marketplace that is more efficient, and better reflects the return on investment for such efforts.
Although the ability to tie offline and online data would thus be highly beneficial to the marketer, the use of offline data in connection with online marketing—most specifically including PII such as name, address, telephone number, and email—creates a risk that the privacy of the consumer may be compromised in the use of this information. Furthermore, because of these important concerns about consumer privacy and in particular the use of PII in online marketing, the use of PII may be prohibited or restricted for certain online marketing applications by applicable laws or regulations, which can vary widely between jurisdictions. Protecting a consumers' online privacy has been recognized as a matter of paramount importance by consumers, governmental entities, individual marketers, and by industry and trade organizations that represent marketers, such as the Direct Marketing Association. Current efforts to improve and better understand the effectiveness of online consumer marketing are thus restricted relative to offline marketing, due to these important limitations on the use of PII for online marketing activities.
Retailers often work closely with marketing services providers in order to improve their marketing efforts. The marketing services providers may have access to large repositories of consumer data, which may include far more information about a retailer's customers than the retailer itself maintains. Such information may enable the marketing services provider to provide data hygiene (i.e., the standardization and deduplication of data) and the enhancement of existing data with additional information valuable in marketing efforts. Such services have long been provided in connection with, for example, direct mail advertising and telemarketing. But bringing this wealth of data into the online world raises important privacy concerns. A method of leveraging all of this data in online marketing, while also ensuring the privacy of personal information about the consumers to whom such marketing is directed, would be highly desirable.
Certain limited efforts have been made in the art to address this disconnection between online and offline marketing, and/or to address concerns about the use of PII for online applications. Some attempts involve the reuse or mild obfuscation of identifiers assigned to consumers and linked to the consumers' PII before putting the identifiers in environments in which the consumers are intended to be de-identified. Because of the reuse of these identifiers, however, these environments do not adequately protect consumers from having their personas re-identified. Examples include using an encrypted identifier into a pixel call; picking up an identifier associated with an individual when logged into a webpage, and then passing that identifier along with site visitation data or ad impression data; and various attempts to use non-dynamic IP addresses.
Many current efforts for identification of online consumers rely on cookies, that is, small files that are written to and stored on a consumer's computer or other device when a particular website is visited. Cookies can contain information that identifies a device used by a consumer without including PII of that consumer. This cookie data is generally nothing more than an identification number. A single consumer may have multiple cookies assigned to their online persona, such as would result from using many different devices while interacting with the online world. Such devices may include a work desktop computer, a home laptop computer, a smartphone, and a tablet, for example. Likewise, a single cookie may actually be associated with multiple consumers, such as two or more people living in the same household who share the use of a single computer. Accurately resolving these cookies to a single instance of a particular consumer may be seen as critical to the success of efforts to use cookies as part of a targeted online advertising effort.
Existing attempts at cookie resolution are often inconsistent and unreliable, because their base system for identifying consumers is not sufficiently accurate. The use of PII to identify a consumer in the context of a cookie is not a workable solution, due to the privacy concerns that have already been described. An effective system for identifying multiple cookies that pertain to the same consumer, but that simultaneously avoids the transmission and/or remote storage of PII in order to protect the privacy of the consumer, would be highly desirable. It may be seen that the problem of cookie resolution is also a factor in analyzing the effectiveness of marketing campaigns; without effective resolution, it is not possible to accurately understand who is actually being marketing to and then attributing a sale (online or offline) to that marketing event. The result is a continuing inefficiency in the marketplace for online advertising, a lower return on investment for marketers, and the delivery of marketing messages to consumers who are uninterested in those messages or find them irrelevant.
The present invention relates generally to an apparatus and method by which marketers may associate their wealth of consumer marketing information with online consumers, but by which no personally identifiable information (“PII”) about the consumer is ever made available outside of a protected data environment. Because the PII is thus not exposed, this new approach allows for the advantages of resolution and accurate targeting of marketing messages in an online environment, without the privacy risks that would be associated with the transfer of this type of information. In various aspects, the invention allows online marketers the ability to associate their marketing data to the same consumers they do today, only without the presence of PII. The marketers are able to use this data to show targeted offers to consumers in an online environment, such as webpage banner ads, in a manner that is consistent with the marketing offers the consumer sees in offline channels, such as direct mail. In addition, because the data is being joined consistently across channels, marketers may analyze the impact of marketing campaigns across both “identified” efforts (i.e., using PII) such as direct mail and email, as well as “de-identified” efforts (without access to PII) such as online banner advertising. The result is seamless multichannel marketing, with increased marketing capabilities for the retailer and the delivery of marketing messages that are more likely to be relevant for the consumer, while simultaneously maintaining consumer privacy.
In one aspect of the invention, a marketing service provider maintains a cookie pool and ties one or more of those cookies to an anonymous link. This anonymous link is based on an internal consumer link used by the marketing service provider, but because it is anonymous may be used externally to protect privacy and avoid a distributor or other party from using the identifier in an inappropriate manner. The marketing service provider's cookie pool may then be tied to “foreign” cookie stores, such as those maintained by distribution partners of the marketing services provider. Data may then be uploaded from a marketer's environment (in which PII is maintained) into the marketing service providers' databases, in certain cases being special protected database areas that are de-identified, that is, that contain no PII data. Maintaining this de-identified data separately prevents misuse of PII. That data is then associated with a cookie ID for distribution based on the marketing service provider's cookie pool and the foreign cookie store.
Again in one or more aspects of the invention, identifiers are associated with each of the consumers in the protected environment, but the identifiers are anonymous links specially created for this environment. A hash algorithm is used to ensure that these identifiers may not be used to reconstruct the actual internal consumer link used by the marketing services provider. These special identifiers, in certain embodiments, may also be particularly calculated with respect to each individual partner that uses this data to result in partner-encoded links; in this way, the marketing services provider may prevent multiple partners who use its services from surreptitiously sharing data using the identifiers in a way that would circumvent privacy laws or applicable industry standards. This special encoding further protects the privacy of the individuals about whom the information pertains.
In these various aspects, the invention supports a variety of new business initiatives involving marketing and marketing analytics, as well as continuing to support strong privacy protection as set forth by applicable regulations and best industry practices. The invention allows for the use of PII-based marketing data from the offline world by moving the data into the de-identified online world without including the actual PII. Existing marketing databases, formerly only usable for offline marketing efforts, are thus extended into new channels. Retailers and other marketers may thus leverage their traditional marketing data for online targeting, and they are also able to analyze the impact of their anonymous, online campaigns on sales or other conversion metrics where PII exists, in a way they could not achieve prior to the current invention.
These and other features, objects and advantages of the present invention will become better understood from a consideration of the following detailed description of the preferred embodiments and appended claims in conjunction with the drawings as described following:
Before the present invention is described in further detail, it should be understood that the invention is not limited to the particular embodiments described, and that the terms used in describing the particular embodiments are for the purpose of describing those particular embodiments only, and are not intended to be limiting, since the scope of the present invention will be limited only by the claims.
In various embodiments, the invention allows for the use of consumer information pertaining to an individual that is based on Personally Identifiable Information (PII) such as name, address, telephone number, and email, but which can be de-identified in a manner that does not allow the data to be re-identified by an outside party. In this way, the data may be used for online marketing without a loss of privacy for the consumer about whom the information pertains. The software, processes and computer hardware utilized for these methods and systems further allow data, once de-identified, to be associated with online cookies for individual consumers. In doing so, the data that originated offline can now be utilized in the online ecosystem to provide a more comprehensive, multi-channel marketing experience. Data from a database that contains PII information may thus be imported into an environment where online, non-PII data is maintained about consumers, such as web browsing, without allowing the PII to be transferred outside of a secure environment.
In one of many possible applications, an automobile brand owner may wish to target its online advertising to those consumers who are currently in the market for an automobile, and whose income would be appropriate to the range of vehicles offered by this brand. It may be seen that the automobile brand does not necessarily need the name of the individual consumers in order to achieve its objectives, but rather requires only that its online advertisements are in fact delivered to those consumers mostly likely to make a purchase based on the identified characteristics. In various embodiments, the invention provides the ability for the automobile brand to target its advertisements to a particular segment (identified, for example, by being in market and within a certain income range) without providing any PII concerning these persons to the marketer. Furthermore, in various embodiments the invention allows for the automobile brand to perform analytics on its marketing campaign, using online advertisement delivery and views, and correlate those accurately to the sales that actually resulted at its dealerships in the offline world, again without providing PII that pertains to the online marketing effort.
The present invention in various embodiments operates in offline and online marketing spaces that include a number of different roles for various providers. Marketing Service Providers (MSPs) are companies that have provided traditional offline database marketing services and often manage the offline prospect or customer databases for large companies. They are typically entrusted with the client's marketing data and the processing of that data, including the ability to recognize consumers based on PII. Match partners are typically companies that have websites or relationships with companies that have websites that collect a consumer's PII, usually in exchange for content, or services (ring tones, coupons, giveaways, ecommerce sites, and the like). These match partners are required to give careful notice to consumers of how their information will be utilized, as well as a choice to opt-out. Distribution partners are typically any online company that utilizes data for targeted advertising or to pass the data on to other online companies that can provide targeted online advertising based on the data. These companies typically are working only with cookies, and cannot or do not want to be exposed to PII about the consumer. Examples include an ad exchange, an ad network, a data management platform (DMP), or demand-side platform (DSP). A reach partner is a company that has the ability to tag many web pages and therefore has an opportunity to do an identifier synchronization of cookies with multiple other companies. A reach partner then facilitates the sharing of IDs between these various companies.
In broad overview, a process according to certain embodiments of the invention may be described with reference to
Anonymous links used in the uploaded, non-PII area of MSP block 16 allow data to be passed from the PII environment to the non-PII environment and correctly overlaid in the non-PII environment to the same consumer, only with no personally identifiable elements that will connect the data to the identity of the consumer. The anonymous link is created through a number of one-way, secure, and irreversible transformations utilizing a multi-step process and standard cryptographic functionality as set forth herein. These processes make it theoretically, let alone practically, impossible to reconstruct the original identifier consumer link from the anonymous link by a party outside of the marketing services provider. Data may thus be correlated with a particular individual for online marketing purposes, but the identity of that individual cannot be determined based on the information that is provided for online marketing.
Referring now to
In a first step of the process for moving information about such customers into an environment that is secure for online marketing, an extract file 12 is constructed that contains information concerning all or a subset of the consumers about whom data is maintained in client PII-based database 10. Various data elements may be included in extract file 12, based on the application for which the data is provided, for example age, gender, marital status, income level, or purchase history.
The data in extract file 12 may be structured, in certain embodiments, in a typical format in which the file consists of a large number of records, each record pertaining to a particular customer, and each such record being divided into multiple fields that each contain a certain type of information about the customer associated with the record. Alternatively in certain embodiments, the data in such records may be taxonomized, either prior to processing as described herein or as part of the processing of pulling the data from a traditional field format into a taxonomized format. Taxonomizing is the replacement of typical field names and positions with standardized IDs that pertain to particular data and are generally known to the parties that are utilizing the data. For example, male gender may be taxonomized as “3001,” and an income of $75,000 per year may be taxonomized to “13027.” It may be seen that by using taxonomization, the data is no longer reliant upon field position or the knowledge of any particular fields or data format, as long as the taxonomy IDs are known to each party using the data. Thus the data may be presented in any order in the records. Taxonomization has been shown to improve file processing speeds, which is particularly important on very large files that contain a large number of consumer records with many data points concerning each consumer.
In addition to the other data in the records of extract file 12, whether taxonomized or in a standard format utilizing fields, one or more consumer links may be supplied for each customer record in order to uniquely associate the data that pertains to a particular customer in a record with that customer's identity. Various types of consumer links may be used in various embodiments of the invention. These consumer links may be fields that comprise numbers, alphanumeric characters, or any combination in various embodiments. In one example, the consumer links may be those as used in the AbiliTec consumer linking product offered by Acxiom Corporation. The AbiliTec linking system providers an identifier that is unique across a universe of consumers, such as, for example, all consumers in the United States. There are identifiers in the AbiliTec linking system that uniquely identify particular consumers (AbiliTec Consumer Link) and particular addresses (AbiliTec Address Link) as well as households (AbiliTec Household Link), and the connection between a consumer and an address over time may be represented by connections between these types of identifiers. (For purposes herein, “consumer link” will generally refer to all types of possible links, including but not limited to all types of AbiliTec links, including the AbiliTec Consumer Link, AbiliTec Address Link, and AbiliTec Household Link.) Using these types of associations, each identifier may be uniquely associated with a particular consumer, regardless of whether there are multiple records that contain information about that individual consumer. Multiple records that contain information about the same consumer or same address are those associated by the fact that they are both linked to this same consumer link. This allows the system to accurate determine that two records actually pertain to the same individual consumer, such as a consumer who has moved or changed names due to marriage. If the data in client PII-based database 10 is not already linked with AbiliTec identifiers or other such consumer links due to earlier processing, then those may be applied to the data in each record that is to be included in extract file 12, either before or after extract file 12 is constructed. The use and construction of AbiliTec identifiers, and the association of those identifiers with consumer data, is described in U.S. Pat. Nos. 6,523,041 and 6,766,327, which are each incorporated by reference as if fully set forth herein.
In various embodiments, a control file 14 may also be constructed along with extract file 12. The purpose of control file 14 is to provide instructions for the automatic processing of data from extract file 12 by the provider offering the services described herein. For example, it may specify the meaning of PII fields in extract file 12 and/or contain taxonomization instructions for the data elements in extract file 12. In alternative embodiments, control file 14 may be incorporated with extract file 12, or may be omitted in lieu of other forms of instructions from or related to the client who maintains client PII-based database 10 to the provider offering these services. Both extract file 12 and control file 14 may be sent by any of numerous known means, including by electronic transfer of the file over a network connection, such as by transfer over the Internet.
Once extract file 12 is created from client PII-based database 10 and control file 14 is prepared, the marketing services provider receives extract file 12 into restricted-access area 16. Restricted-access area 16 may be implemented as a database or multiple databases in any of many known forms of computer storage media. The purpose of restricted-access area 16 is to provide a secure data storage facility where data can be manipulated without the use of PII in order to ensure the privacy of data used in, for example, online marketing transactions. The data from extract file is initially received in landing zone 5 of restricted-access area 16. Landing zone 5 provides are area where PII may be removed from the data before it is passed into an area where PII is not allowed for further processing. In certain embodiments, the data may at this point be analyzed to determine if AbiliTec identifiers or other consumer links are present, and if not, then the data may be cleaned, standardized, and processed to receive consumer links. The records in this data will then be appended with the consumer link for each consumer in such case. Once this is completed, the data is stripped of all PII other than the consumer links. In this way, the data is made ready for further processing in the anonymous area 19 of restricted-access environment 16, where no PII is allowed in order to fully protect consumer privacy.
Although all PII other than the consumer links has now been stripped out of the consumer records, the consumer links themselves may pose a risk because they are used internally by the marketing services provider to link data associated with a particular individual. The consumer links are in these systems associated with PII for the consumers about which they pertain. A party wishing to maliciously reconstruct PII from data in anonymous area 19 might thus use the consumer links in an effort to achieve this objective. In order to prevent any possible misuse of the consumer links by a party that might wish to surreptitiously identify the consumers associated with each of the records, these consumer links are modified in a manner to prevent any such misuse. The process results in the creation of an anonymous link from each consumer link. The anonymous link is a de-identified link that is privacy friendly and completely anonymous, because it is not stored in any systems anywhere, either within the marketing service provider's systems or outside of them, in conjunction with a name, address, telephone number, email address, or other PII associated with a consumer, and further cannot be reverse engineered to an identifier that is stored in any database with PII for a particular consumer.
In certain embodiments, the anonymous link is created from a consumer link in a process as illustrated in
In second hash step 36, a second secure salt from salt store 32 is used to again apply a one-way hashing algorithm, this time being applied to intermediate value 34. Various hash functions may be applied at step 36 as are known in the art, including the application of SHA-1 in this second hash step as well as the first hash step. The output of this step is hashed value 36, which in certain embodiments may be a 20-byte hash, which is then converted and stored as a base-16 encoded, 40-character alphanumeric string. Although two one-way hash functions are applied in this particular embodiment, the invention is not so limited, and may utilize only a single hash or be extended to the application of any number of hash functions.
In order to utilize this process in global marketing efforts while simultaneously keeping identifiers separate for particular regions, an optional region code step 40 may be conducted, in which a regional code identifying a region (such as a particular country) may be applied to hashed value 38. In certain embodiments, this is a two-character code that is prefixed to hashed value 38 as a concatenation. The final result is anonymous link 26, which in certain embodiments is a 40-character (or, in the case of a regional code being prefixed, 42-character) alphanumeric string. For example, a consumer link 22 for initial processing could be “0000US01ABCDEFGH,” and the resulting anonymous link could be “183FC2C3A760B11C863856A46C2DEDBECC21512345.”
It may be noted that the salts from secure salts store 32 are secure in certain embodiments because they are stored in the system configuration in an encrypted form; the encryption is certain embodiments is password-based AES, with the password hidden within the programming code, so that it would be impossible for a layperson or an intruder to see the password. It will be apparent from the process described herein and illustrated in
Taxonomization, as described above, may in certain embodiments be performed on records 20 at this point after the anonymous link 26 is created for each record. Control file 14 may optionally contain instructions for providing taxonomization processing to the records, such that data that is values distributed in columns or data in standard data fields is turned into order-independent numeric data through the taxonomization processing.
An optional step in certain embodiments once anonymous links 26 are created is to randomly sort the records such that they are presented in an order that is different, and unmatchable, to the order that the records were originally provided into the restricted access area 16. This is a further security measure to prevent a party that obtained access to both the input and output versions of extract file 12 from being able to compare them and re-identify the data that is now associated only with the anonymous links 26 and no PII data.
In the match partner processing as described above with reference to
In certain embodiments, the process for creating partner-encoded links 50 is as set forth in
The partner-specific encryption key that corresponds to the partner for which this data will be used is read from partner-specific encryption keys store 54. These encryption keys are created prior to processing. At step 55, it is determined if the encryption will include a random initialization vector, which are generated as needed. Use of the random initialization vector will result in a different partner-encoded link 50 from the anonymous link 26 each time the process is performed. There may be cases, however, where this is not desirable, such as where the partner-encoded link 50 is serving simply as a disguised anonymous link 26, and it is important that the same partner-encoded link 50 be generated with each processing. Encryption occurs at step 52 for the case of a random encryption result, or at step 53 for the non-random result, in either case using the appropriate encryption key from partner-specific encryption keys 54.
At encoding step 56, the result of encryption is encoded using the standard Base64, URL-safe codec. In the event of a single anonymous link 26, the result will in certain embodiments be a 43-character string, while with two underlying anonymous links that were concatenated as described above, the result will be a 64-character string. A partner ID from partner IDs database 60 is then prefixed to this string at prefix step 64. The purpose of the partner ID is to uniquely identify this partner from the universe of all possible match partners. If an initialization vector was used, it is also prefixed to the result. The partner ID and initialization vector are necessary in order to make decryption of the partner-encoded link 50 possible. The final result is either 49 or 70 characters long in certain embodiments. In a particular illustrative example, the anonymous link 26 may begin as the character string 183FC2C3A760B11C863856A46C2D5DBECC21BF2512345, and the resulting partner-encoded link 50 may be the character string QE1005HX1fqX1cljgWLFwLGrBY92f3NO5FEdpPaouxQ0a5qEE. In this case, “QE” is the initialization vector and “1005” is the partner ID.
Referring now to
Real-time processing utilizing the partner-encoded links that are now overlaid onto the match partner's data may be described with reference to
Referring now to
It may be seen that the ability of this process to produce meaningful results relies upon the overlap between the marketing services provider and the distribution partner; the greater the overlap in their cookie pools, then the more effective this process will be at ultimately delivering targeted advertisements that are meaningful to the consumer. To help increase the overlap between the marketing services provider cookie pool and distribution partner cookie pools, a reach partner may be utilized as shown in
The foregoing processing enables the pushing of data from restricted-access area 16 to a distribution partner as shown in
It may be noted that there may be a many-to-many relationship of anonymous links to cookies in the various embodiments. In the case where there are many anonymous links associated with a single cookie, which corresponds to the case of numerous individual consumers using a single device, in certain embodiments the latest individual seen will be used to associate data to that cookie. In the case where one anonymous link is associated with many cookies, indicating a single individual using multiple devices, then this individuals' data will be associated with each of the cookies tied to it.
It may be noted that the various embodiments of the invention do not in all cases require the particular order shown in the illustrated embodiments, or necessarily require any sequential order, to achieve desirable results. In addition, other steps may be provided, or steps may be eliminated, from the illustrations, and other components may be added to, or removed from, the described systems.
Each of the various systems as used in communication with the marketing services provider, distribution partner, match partner, reach partner, and other parties may be implemented as standard computer servers or groups of servers, as are well known in the art. These machines may be specially programmed with software to implement the algorithms as described herein, the result being special-purpose computing machines. These machines may be connected together using networks such as the Internet. Standard web browser software or other software used to access the Internet from various client devices may be used. Such devices include desktop computers, laptop computers, smartphones, and tables, as non-limited examples.
Unless otherwise stated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present invention, a limited number of the exemplary methods and materials are described herein. It will be apparent to those skilled in the art that many more modifications are possible without departing from the inventive concepts herein.
All terms used herein should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced.
